most gasoline !.How much diesel is released by buses compared to cars?
Hopefully, not diesel at all - that would indicate a leak in the fuel system.

As for unburned hydrocarbons in the exhaust, particulates, CO2 etc. etc. than almost certainly the bus. But per passenger for a less-than-empty bus, the bus is greener.



I found a couple of figures for NOx - between 25-50 grams/mile for a diesel bus engine, and between 2-5 for a carHow much diesel is released by buses compared to cars?
A bus should not emit any diesel into the air. If they did there is a leak somewhere. Most cars run on gasoline and cannot emit diesel.
a lot
