Hydrogen Engine

Cummins Paves the Way with Hydrogen Engine of The Future

Hi everyone, Kary here and today I’m going to be talking about how Cummins is paving the way in the world of Diesel Trucks. It’s not news that the price of diesel has steadily been on a hike, defeating the purpose of why we all love and choose diesel trucks.

Do you remember when we talked about Cummins claiming they have a fuel agnostic internal combustion engine that can practically run on any fuel? Well, it looks like they’ve gone ahead of the times and made it a reality.

The current state of the world and the push for cleaner-burning fuels, more energy, less waste and the state of the diesel market makes Cummins’s choice a very timely one. As a pioneer in the engine making industry, with decades of experience and the release of countless diesel-powered motors, their current development is genuinely pleasing to the ears.

At an event in California earlier in the second week of May, Cummins had us at a standstill and unveiled their futuristic design- a hydrogen-powered 15-litre engine. This new motor is a part of Cummins new fuel-agnostic platform. The platform features a wide array of engines capable of functioning on different fuel types.

It is remarkable indeed what Cummins has in store. If you’ve ever felt bad about diesel from your truck polluting the environment, then the opportunity and choice to do better and keep it safe might be coming to you soon- well, if ‘5 years from now can be considered soon.

Cummins announced that the hydrogen-powered monster engine will hopefully be making it into production in 2027. The project’s entire purpose is to reduce pollutants and emissions that lead the earth further away from sustainability and being green. Looking at the bottom components of the engine, everything seems familiar, but the real magic is at the top of the gasket. That is where each power unit will use various components for the different types of fuel. This is thanks to the necessity of varying fuel injector and valve designs.

Cummins says there will be two options for this masterpiece, a 15-litre engine and a 6.7-litre displacement engine. Testing and major additions are underway to have it released on time 5 years from now. With major companies like Ford and Yamaha teasing us about switching to hydrogen-powered internal combustion vehicles, I truly have high hopes for Cummins. Do you?

In the meantime, we continue to hang on to our diesel engine trucks, of course, because the world’s economy would not survive without heavy-duty trucking. Thankfully, the conversion of the current vehicles into hydrogen-powered ones does not require much modification, according to Cummins. There’s no need to be afraid of the change; instead, let’s look forward with hope and anticipation for what’s to come in the world of truckers.

Trust me when I say we are super excited at Modern Diesel, and we will surely be keeping our eye out to update you with the latest.

Diesel Truck: Best Hacks and Safety Tips to Keep in Mind

Hi this is Kary with Modern Diesel, I’m back to you today with a new blog that is going to help you a lot if you drive a diesel truck. Choosing a cost-effective fuel to meet our auto needs represents the major reason why diesel trucks are preferred by many. Diesel is priced higher than gasoline but more energy can be derived from diesel. This is mainly due to the high mileage of diesel as against the same volume of gasoline.

Diesel trucks make use of compression ignited-injection systems, unlike gasoline vehicles that make use of spark-ignited systems. This method of operation causes air to be drawn into the engine which is subjected to high compression that generates heat.

This creates a very high temperature in the engine. Owing to this extreme temperature and pressure, diesel that is let into the engine ignites. Therefore, there is a need to keep the engines relatively cool at all times. Cooling diesel engines are achieved either by air or liquid.

Vehicles are used across all seasons which includes diesel trucks. Extreme temperatures during summer and winter affect diesel trucks differently and therefore require special care to keep them working properly.

Here are safety tips to keep in mind while using diesel trucks.

Safety Tips For Diesel Trucks

Safety while driving a truck is of highly essential to ensure the preservation of our lives and property. Large trucks are used in conveying bulky goods and fuel. If trucks are not well maintained, the event of an accident could cause a catastrophic disaster. Hacks for driving a diesel truck safely include the following:

  • General safety tips for diesel truck drivers.
  • Summer safety tips for diesel trucks drivers
  • Winter safety tips for diesel trucks drivers.

 General Safety Tips For Diesel Truck Drivers

The following are standard safety practices for truck drivers.

  • Putting On Personal Protective Equipment: Personal protective equipment like a hardhat, safety boots, eye protection, and hand protection should be worn before and while driving the truck. The equipment should also be inspected for faults before usage and replaced if worn out.
  • Carefully Mounting And Dismounting The Truck: All points of contact according to the truck manual should be observed to avoid accidents while mounting or dismounting.
  • Check For Repairs: Check the truck thoroughly for parts that might need repair or maintenance before riding. Also ensure emergency kits such as fire extinguisher, eye wash, spill kit, and first aid kit are in the truck. All hoses, valves, and latches should be secured properly
  • Clean Up Regularly: Windscreen, steps, windows, and mirrors should be cleaned properly to remove all debris and dust. Also, enjoying outings in your truck regularly can enable the accumulation of gunk dirt that can pose a threat to your vehicle. Regular cleaning and removal of gunk is a nice hack for your truck safety.
  • Careful Parking: Diesel trucks should be parked on level ground that is safe from hazards and at least 300ft away from water.
  • Proper Gear Selection: Gear failure is one of the major causes of diesel truck accidents. Therefore, proper gear selection is paramount to maintaining control while driving.
  • Ensure To Meet TDG Requirements: It is of highly essential to have your proof of TDG training handy as well as play cards and other shipping documents while driving a truck especially when traveling.

 Summer Safety Tips For Diesel Truck Drivers

Summer is all about the heat and the thrill of having fun in the sun. However, the same heat can pose a threat to the cooling system of your diesel truck.

Here are essential hacks to help you enjoy your truck and save its cooling system from damage despite the heat.

  • Check the Air Conditioner: As soon as the summer heat sets in, take your truck to a professional mechanic for repair and maintenance to ensure the cooling system is working properly. Delaying till it gets too hot can pose a threat to your truck.
  • Inspect the Tires: Tires undergo wear and tear faster in summer periods as a result of the increase in heat which sometimes gets trapped in them. The safety measure to consider is to ensure a mechanic checks it properly to fix or replace worn-out tires. Also, there are special summer tires that are designed to adapt to the heat of the season.
  • Check the Air Filter: The issues with the air in your truck are not always because of the summer heat. The problem may be your air filter. When the filter is dirty, the truck works extra hard to keep you cool. So, cleaning the filters might be all that is required to have a cool ride.
  • Inspect the Coolant System: The diesel truck can break down once the coolant system malfunctions. It would be very frustrating to have your truck break down under the increasing summer heat. Therefore, having a professional mechanic inspect the coolant system of your truck at the inception of the summer season is great.
  • Replace Fluid Regularly: Checking up on truck fluids regularly ensures the smooth running of your truck. One important fluid check is the oil. Although changing oil is a regular practice for both car and truck drivers, the summer season is a period where truck drivers need to be more frequent in changing the oil. This is because summer is a holiday period that brings about lots of driving travel that burns more truck oil.
  • Inspect The Exhaust System For Repair: The exhaust system of the truck needs to be checked regularly as it could affect the health and environment directly. Problems should be attended to early as soon as they surface. The exhaust system is easily prone to damage.

Winter Safety Tips For Truck Drivers.

The sudden weather change associated with winter poses challenges to many people. The chill from frigid winds, slippery surfaces, and cloudy skies are not felt by individuals alone. Automobiles also freeze in winter weather and therefore adjust to keep working effectively.

Diesel trucks unlike other automobiles require special maintenance to work effectively in winter. Below are ways winter affects trucks.

  • Tires lose pressure when at rest as a result of the cold weather but bounce back once in motion and have gained a little heat.
  • Fluids protecting the engines sometimes cool and thicken which can affect the performance.
  • Other parts of the truck such as the windscreen, wiper, engine batteries all change in the chill of winter weather.

Diesel engines require a great deal of care when temperature drops in winter and here are safety hacks to keep your truck running smoothly in winter.

 Fluid Change In Late Fall: As soon as you approach the end of fall, the time to prepare your truck for the winter weather also begins. One important hack is to change the oil. This is because changing the oil in colder months is difficult as the oil might thicken with the decreasing temperature.

Draining bad oil is difficult when the engines are cold in the winter months. However, driving with bad oil running in the engine all through the chill period can be hazardous.

Aside from oil change, all fluids used in the truck need to be changed at the end of the fall as well. The disadvantages of changing the oil in the winter months are also applicable to other fluids.

There is winter-friendly diesel with zero paraffin wax which makes it perfect for the winter months.

Carry Out Pre-Winter Inspection: Some truck dealers offer pre-winter maintenance of diesel trucks. Getting your truck checked by the dealer at the inception of winter is very important.

Have a complete check of truck parts to rule out faults of any kind to enable a smooth ride in the cold months ahead.

Parts known to be vulnerable in winter such brake cylinders and calipers due to the slippery surface should be checked properly.

Ensure a professional mechanic checks all fittings and make sure they are well greased to avoid squeaking. Also, have the lights and other electrical compartments checked.

Have the batteries checked and replaced if necessary? Since most diesel truck batteries come in twos, it is essential to change both at the same time.

Safety Tips in Winter Months:  Adjusting storage and driving habits in winter months can enable ease of driving diesel trucks. Some of these adjustments include;

  • Before operating, give ample time for the truck to warm up properly.
  • Ensure to park the truck in a heated garage or near walls so that engines do not get cold.
  • Use an engine block heater to keep the engine warm regularly.
  • Remove corrosion build-up from battery terminals regularly.
  • Reduce unnecessary driving as much as possible to save your truck from breaking down in the cold. Trips can be combined or scheduled.

Repair Faults Immediately: In winter, little truck problems can turn into huge ones if left unattended. Repairs should therefore be carried out as soon as they are noticed. Here are some common problems diesel truck drivers complain about in the winter months.

  • Fuel injector failure.
  • Metal rust in the undercarriage.
  • Wobbly steering wheel.

Diesel trucks are great to have, help in fuel management and can convey bulky goods which make their maintenance of immense importance. Some of the best hacks and safety tips to keep in mind enumerated above would guide drivers in both cold and hot weather.


7 Issues Indicating Your Diesel Truck Engine Needs Repair

Hey everyone, this is Kary Sabedra back with another edition of Kary Talks Diesel. Did you know that most trucks in America run on diesel? Diesel offers more fuel efficiency and generates a greater low-end torque, which is more suitable for big trucks.

You can expect a diesel engine to keep running for a long time. As long as you keep up with the right maintenance and repairs needed to keep it in tip-top shape. You should be aware of the common signs that could indicate that your truck requires diesel engine repair services. This way, you can prevent a small problem from turning into a bigger and more expensive problem.

Here are a couple common issues that should have you looking for reliable diesel engine repair services.

Increase In Fuel Consumption

One of the main reasons why people usually choose a diesel-powered engine is that it is more fuel-efficient. You get more mileage from your diesel engine with less fuel. Thus, if you notice that you are making more stops at the gas station or your truck is not traveling as far as it used to on a full tank, then it may be time to take your truck for repair.

A professional diesel engine mechanic can help you diagnose what the problem is and get your diesel truck back to its fuel-efficient ways.

Excessive Knocking Sounds

Anyone who has ever used a diesel engine can attest that these engines are usually louder than their gas-powered counterparts. However, when your engines start producing too much noise. This may be a sign that something is amiss.

A sound you should definitely be looking out for or excessive knocking sounds, or any other sounds out of the ordinary. Knocking sounds that are too loud can be a great indicator that your fuel injectors have an issue. If your fuel injector has an issue. This can mess with the compression of your vehicle, and eventually lower your vehicle’s performance.

Thus, if your vehicle is producing too much noise that you cannot explain, you need to get diesel engine repair as soon as possible.

Too Much Black, Blue, or White Smoke

When it comes to your diesel engine. Too much smoke under your hood or from the tailpipe is always a good indicator of something wrong. Different types of smoke can be great indicators of different issues with your diesel engine.

If your diesel truck is emitting too much black smoke, this can be an indicator of an imbalance in the fuel-to-air ratio. Usually, this means your truck is burning up more fuel than air during its combustion process, causing the truck to release more black smoke. This can be an indication of problematic fuel injectors, a malfunctioning fuel injector pump, or bad air filters.

If your truck is emitting blue smoke, this can indicate that your diesel engine is burning oils. This can be an indicator your oil is leaking into other parts of your truck, which can be a very serious problem.

White smoke, on the other hand, means your truck has leaked into the engine, causing it to burn coolant along with fuel. Not addressing these issues soon can cause even more damage to your engine.

Hard To Start

It is not out of the ordinary for diesel engines to crank a bit before they start running. However, if you notice your engine is taking more time to crank up, or you cannot start at all. This could indicate that something is wrong with the engine.

You need to call your diesel engine repair mechanic as soon as possible. A diesel engine that is hard to start can be an indicator that something is wrong with your fuel delivery or your truck’s compression.

Oxidized Oil

A regular oil change is extremely vital for the health of your vehicle. This is especially true for a diesel truck that has been idle for a long period, say maybe throughout the winter. If your diesel truck stays idle for a while, the oil can get oxidized. This means that air gets into your oil causing bubbles into it and causing contamination. Oxidized oil is a less effective lubricant.

When your truck does not have enough lubrication, this can cause a lot of damage to the moving parts due to increased friction, which can eventually damage your truck engine even more. Thus, you should take your vehicle to your truck for an oil change. Especially if it has gone unused for a while.


Your truck overheating can be a clear-cut sign that your diesel engine has a problem. There are so many reasons why your engine is overheating. Perhaps you have a coolant leak. This is especially common in hot months. Leaking coolant can be an indication that your vehicle’s gasket is damaged or has cracks and requires repair as soon as possible.

A broken cooling fan can also cause your diesel engine to overheat, which may be because of an electrical issue that can be easily repaired if caught early.

Therefore, ensure you are always checking your temperature gauge to see if the engine is hot or if steam is coming out of your hood. It may be time to take your truck for diesel engine repair services.

Losing Power

It is a well-known fact that diesel engines are powerful. Nonetheless, if you notice that your truck is losing its power. Perhaps it no longer accelerates or starts as efficiently as it used to. This could be a key indicator that something is wrong with your truck’s fuel injectors, you have dirty filters, or a loose throttle.

If you start noticing that your track is lacking in power, now may be a good time to visit a diesel engine auto repair shop.

There you have it, 7 signs that could help you know when it is time to reach out to a licensed mechanic like those from Modern Diesel. We help you get a proper prognosis for your diesel truck and ensure it is properly repaired to keep it on the road for as long as possible.
