Another trump not believing in clean air for or future

Oh look a political stunt.

Ok, before we even get into the electric aspect of this lawsuit.... I've always been taught that diesel engines do not work by combustion. They work by compression.
Have I been lied to? Or is this lawsuit missing the mark? But either way, I do not see electric engines as being a viable alternative any time soon.

No diesel is still internal combustion. The difference is that diesel combusts due to compression as opposed to a spark plug like gasoline.

Ok, thanks for clarifying. So, where does the spark come from? What's the source of ignition? Sorry- my question is not directly related to the original post, but I'm still curious.

Diesel engines have a much higher compression rate than gasoline engines. Diesel engine compresses just air and then at peak compression, the fuel is injected and the heat of the compressed air combusts the fuel. Gas engines have the air fuel mixture compressed and then the spark plug fires and combusts the fuel. Diesel can have a 14:1 to 28:1 compression ratio, which means that the volume of the cylinder at bottom dead center is 14 to 28 times larger than the volume at top dead center. While gas engines have a compression ratio somewhere between 8:1 to 12:1. The reason for fancier cars needing higher octane gas is because the octane prevents predetonation (which would be combusting off of compression instead of spark) engine knocking is literally the sound of gas igniting in the cylinder before the spark. This is not good because everything is timed precisely to have the cylinders work together to produce peak power. When the engine knocks it is literally forcing the piston back down when it is still supposed to be traveling up

Well, I'll be damned. I believe I've misunderstood for all these years. That's an excellent explanation, btw. Thank you!
