The cost of a DISC engine is best estimated from the cost of a diesel engine, since the fuel injection system complexity rivals ...
The major advantage of the diesel engine over the gasoline engine is its high fuel efficiency. Diesels are more fuel efficient t ...
design results in smoother combustion with less noise and lower NOX emissions. However, heat transfer from the prechamber and pr ...
test results for 1994 cars were utilized to develop estimates of diesel fuel efficiency benefit over a gasoline engine.6l Table ...
The key to diesel’s future in the United States is its ability to further reduce emissions. The manufacturers interviewed by OTA ...
These benefits are not necessarily additive but hold the promise of a total NOX reduction of over 50 percent from the current ba ...
DI diesel over a two-valve gasoline engine is $1,160 to $1,260. Costs for a V-6 are estimated $1,570 to $1,680, and for a V-8 at ...
