Are diesel’s days numbered? A view from a trip to BYD’s electric bus factory
I hate seeing this conversation about diesel when we should be having this discussion about gasoline.<p>Gasoline engines have lesser thermal efficiency and lesser torque potential than diesel engines. If you&#x27;re going to get rid of one or the other, get rid of gasoline vehicles.<p>Diesel engines have a longer stroke, cooler combustion, more flexibility with air&#x2F;fuel ratios, extreme wear tolerance, lower rotational speeds, and cost the same with similar complexity to gasoline engines. They are also more economical in practice because their extra low-end torque gives them (arguably) a drivability advantage which lends itself to increased MPG.<p>They are superior to gasoline engines in every way. And because they can run with air&#x2F;fuel ratios anywhere from 10:1 all the way to 60:1 they can easily run a mutitude of different fuel&#x27;s with only minor software adjustments.<p>So please, stop shitting on diesel. It&#x27;s ignorant to the fact that you probably drive a gasoline powered car that does more damage to the environment per gallon of fuel burned than a diesel bus.
