Environmental indicators of dual-fuel hydrogen engine

E3S Web of Conferences, 2023
Hydrogen is considered as a promising gas engine fuel for diesel engines. The problems that occur when converting engines to work on hydrogen are presented. Reliable ignition of hydrogen in the engine is achieved by implementing a two-fuel cycle. In this case, hydrogen ignites from the diesel fuel combustion.

Dual fuel diesel engine operation using LPG [PDF]

IOP Conference Series: Materials Science and Engineering, 2016
Diesel engine fuelling with LPG represents a good solution to reduce the pollutant emissions and to improve its energetic performances. The high autoignition endurance of LPG requires specialized fuelling methods. From all possible LPG fuelling methods the authors chose the diesel-gas method because of the following reasons: is easy to be implemented ...
