Traditional gasoline engines use port fuel injection, where fuel is mixed with air before entering the combustion chamber.

This paper presents experimental test results of a new compressed natural gas direct injection (CNGDI) engine that has been developed by modifying a multicylinder gasoline port injection engine. The ...

Diesel truck owners often look for ways to get better fuel economy, add torque, and reduce emissions. One modification that’s ...

This paper introduces a complete simulation model of a direct power injection (DPI) setup, used to measure the immunity of integrated circuits to conducted continuous-wave interference. This model ...

The dual permanent magnet machine (DPMM) possesses the characteristics of high torque and low speed which is suitable for direct-drive equipment. Because of the low magnetic reluctance of this motor, ...

Injecting fuel directly into the combustion chamber, however, lets the engine use a higher compression ratio without fear of early detonation as the fuel actually acts to cool the chamber. That can ...
