Assessment of Fuel Economy Technologies for Light-Duty Vehicles

Light-duty compression-ignition (CI) engines operating on diesel fuels have the highest thermodynamic cycle efficiency of all light-duty engine types. The CI diesel thermodynamic cycle efficiency ...

The first vehicle with a direct-injection diesel engine may be older than you realize

If you think direct-injection diesel engines made their debut in the 1980's, think again. The first diesel without extra ...
