  They’ll run on CNG

    No they won’t, unless they’re built with a gasoline based engine, which almost no one orders, because the mileage to fuel ratio, cost, and power are terrible for OTR hauls.

    Diesels will run on lots of less refined oils using only the heat of compression, like kerosene and fuel oil, as well as being able to run on their own oil (diesel runaway). However CNG, Propane, Gasoline, and other commonly sparked fuels will, in very short order, catastrophically destroy your diesel engine because they detonate at much lower compression than diesels require.

    Furthermore, you’d ruin your high pressure fuel pump as gasoline doesn’t have the required lubricity. The injectors would probably be fine, but your pump and your cylinders/pistons/crank/rods/mains would be having extremely bad days.

      Somebody down voted you for making them learn something from a shitpost hehe

      Diesels get modified to run CNG all the time where I’m from, but I’m not entirely sure how much extra modification they require. LPG conversations on gasoline engines are much simpler, but the diesel CNG conversions exist too - just not for passenger cars generally.

      I assume that have to lower the compression ratio somehow and that’s why they cost so much more than the gasoline to LPG conversions

        Diesels that run CNG/Prop run it WITH the Diesel as an additive/power boost/starter aid. It is not a replacement fuel.

        Propane/CNG injection is done through the intake manifold, not the injectors/fuel system. A diesel cannot and will not run solely on sparkable fuel.

  Shhhh, let him fire it up

    I mean, it will run on gas once…

    Make sure to make a video.

    If you can also write an article, you can call it ‘science’

  I wouldn’t be surprised if an old mechanical injection diesel would run on petrol. You can definitely run them on a mixture of both petrol and diesel, as well as kerosene.

    Old mechanical injection diesels use the same principles of physics as the new ones do, just with electronic timing and fuel injection. I mean, the engine may on this stuff at least once. For some length of time. You can also do pretty much anything at least once. It’s the consequences that are the issue. You’re just doing the damage slower by diluting the fuel that doesn’t belong.
