Re: compression ignition
Gasoline engines run on spark ignition , not compression ignition . Because diesels run such high compression, they have to be built of much stronger materials than gasoline engines . To run a gasoline engine with the compression ratio of a diesel would require a super high octane gasoline and I don't think there exists any such a blend . Also , the gasoline engine would require such extensive strengthening modifications that it would not be economically viable to do so . The diesel engine can be easily modified to not only outperform the gasoline engine , but it also will get better mileage !
