    From watching various large diesel truck videos it is noticed that the new diesel trucks that have all the latest in emissions control equipment such as selective catalytic reduction and diesel particulate filters now have a serious reliability problem. The problem is that these emission control systems break down frequently resulting in the truck spending a lot time in the repair shop and less time on the road. These breakdowns are very expensive for truck drivers and truck companies. So there is a great need for the emission control systems to be a lot more reliable and last a long time.

    A lot of comments and even the video will mention that a diesel engine is more fuel efficient and then fail to explain why.
    Two of the big reasons:
    1) when under load a diesel engine uses excess air in the cylinder as a coolant whereas a gasoline engine uses excess fuel. I.e. a diesel will run very lean and use the excess air to carry heat away whereas a gas engine will run rich and use excess fuel to carry heat away.
    2) compression ignition results in very rapid combustion whereas a gas engine has a relatively slow flame front. The rapid combustion combined with the high compression/expansion ratio enables more useful work to be extracted from the energy in the fuel.
    Also, yes diesel fuel is more dense than gasoline but that is not relevant in a thermal efficiency calculation.

    Most semi truck engines like cummins don’t rev past 2100 rpm. Cat c15 and c16 are around 2400 rpm.
    I also wouldn’t say newer Diesel engines are better. Cus they all have sensor and missions issue, I’ve seen more and more company and even owner operator, sell there new trucks and buy older truck that is pre emissions. So anything be before 2007 or older. You see a lot 1990 to 2005 trucks still on the roads with older Cat engines. Cus new engines are SHIT. Newer trucks always in shop while older trucks are running circles around any new truck.
    They plug up, sensors and computer issue, along def and emission issue. Simple because these new turbo diesel emissions can’t breathe. So they slowly kill itself. They not more efficient Cus spend more time in shop for repairs.
    I’ve seen few videos where truckers are looking at diesel hydrogen as option. Cus let’s diesel burn cleaner and hotter. Cummins is working on hydrogen engines.

    Torque is a result of power divided by rpm. The lower rpm an engine has the more torque it produces. With the right gear ratio you get the same torque to the wheels, which is what matters.
    It's the torque curve that's different between a gas and a diesel engine:
    A gas engine produces the maximum torque at a pretty high rpm and at idle the torque is pretty poor.
    A "free breathing" diesel produces it at a pretty low rpm and torque is there already at idle. With a turbo- or supercharger you can extend the maximum torque to a wider rpm range on a diesel, which makes it more "flexible" than a gas engine. This is why turbochargers have been used on diesels a lot before on gas engines.

    Because gasoline engines aren't used in trucks or other heavy machines anymore is the reason why they don't need to be so so robust and heavy. A long time ago, before diesels were used in trucks, gas engines were pretty heavily built. A gas engine can last as long as a diesel, if they are built the same way.
    Diesel fuel has an approx. 13% higher density than gasoline. The energy content per weight unit is pretty much the same for both, but you need more volume of gas to get the same energy.

      Yes and no. You can generate the electricity without emissions. But even if you would use coal for it: 1) electric motors are way more efficient (less KWh needed). 2) bigger generators (powerplant) are more efficient then a small one (onboard combustion engine)

      @@1987tijgertje electric motors aren't much more efficient then a transmission in power losses. Every time power is converted there's losses involved.
      With a electric vehicle you are
      1. Generating electricity
      2. Transmitting it
      3. Stepping it up
      4. Stepping it back down
      5. Stepping down again
      6. (Assuming fast charging) stepping up again.
      7. Charging the battery
      8. Transmitting
      9. Converting the electricity to a magnetic field to make rotational force
      At each step, power is being lost.
      On a ice vehicle you're
      1. Generating power
      2. Transmitting through the transmission
      3. Transmitting through the diff (skipping this step in the case of a front wheel drive)
      The reason electric seems more efficient is that the power isn't being made on sight. The engine is the generator off sight making it so the car is all transmission, so the efficiency of a electric car is the power losses only. A apples to apples is to compare the power losses through the transmission only of a ice vehicle.
      Also because of the limited power density, electric cars themselves are built to be as efficient as possible, being made more aerodynamic, having stiffer tires and such while also doing tricks such as regenerative braking (a trick that ice vehicles are capable of even without using electric hybrids). Because of the increased energy density of gasoline or diesel compared to a battery, a ICE vehicle can be build without as much consideration to sheer efficiency of the rest of the vehicle, so they can use softer tires with less idealized tread patterns and they can afford to have less efficient shapes.
      The effect of this is shown most starkly when a electric vehicle is asked to tow, or haul oversized odd shaped cargo that ruins the base vehicle's aerodynamics and rolling resistance. While on a ICE vehicle when towing and hauling, the range changes only slightly, on a electric vehicle, the range decrease is upwards of 3/4 of the original range. A prime example of this is people who found while towing a car with their Ford lightnings and similar with rivian, the range dropped from 300 to 500 miles down to sub 100 miles.
      When a ICE vehicle is built around pure efficiency, their efficiency is eye watering. Examples would be like VW's diesel car that was rated between 200 to 250 miles, per gallon.
      Emissions free power generation all has its negatives though, such as the massive landfills needed for wind turbine blades. Disruption of marine life due to very loud vibrations from off shore wind. Creating blinding hazards for pilots and cooking birds from the sky in the case of solar. Disruption of fish migrations, halting sediment flows, flooding habitat for both humans and animals and even altering the planet's rotation in the case of hydro.
      That's to say nothing of the environmental and humanitarian disaster that is mining for the various elements in batteries. My personal favorite is the plan to scrape the deep ocean floor causing untold permanently damage to a environment we don't understand and don't understand the impact of.

    The future will remain DIESEL! But hybridized with electricity. Best of both worlds, fuel efficient burning of Diesel to generate electricity at optimized engine RPM and electric motors with instant torque from zero speed. Imagine 50% reduction in diesel consumption. The best kept secret or the most difficult thing for common people to understand/grasp is that once an object on wheels start moving, you do not need to provide the same amount of force to maintain that motion. Still do not get it, have a look at diesel locomotives which uses electricity to turn the wheels but the diesel to generate the electricity on the tracks themselves. The diesel engines will require a common rail which works at 2,000 bar and stratified injection.

    Diesel has Longer run time because it burns slower due to its thicker density. more torque due to high compression. Has less maintence and less parts needed. relies on its high compression for ignition.
    Gas engines have lower compression thus has less torque numbers. Spark is needed to run the engine. Also gas has thinner density and is why it burns faster.
    Both fuels are very different
    In fuel density
    Diesel burns slower and has thicker density Diesel has a longer run time.
    Gas burns faster and has thinner density Gas has a shorter runtime.

      Less parts and less maintenance is true only for old "mechanical" diesels that didn't need electricity for running. I'm pretty sure that modern diesels with common rail fuel injection and all kind of emission control and reducing systems don't have less parts than gas engines and they need electricity to run too. Gas engines don't need "AdBlue" or other systems that don't even seem to be very reliable.

    Stop it with the torque myth. Torque is pretty much what dumb people say when they want to sound smart. There is nothing special about torque making it extra suitable for truck engines. All ICE engines have gear boxes. If the engine was less torque, it would simply be geared differently.
    What does matter is how wide the torque band is, and diesel engines really dosn´t have that wide of a band.
    Similarly, while diesel engines tend to be more durable, this is really a effect of them being built to be more durable, not that they automatically are more durable.
    It alls come down to efficiency.
