Experimental study on the effect of load and air+gas/fuel ratio on the performances, emissions and combustion characteristics of diesel–LPG fuelled single stationary ci engine

Engineering Reports, 2023
Due to the issue of combustion stability when using natural gas and the problem of knocking when using both natural gas and hydrogen, liquefied petroleum gas (LPG) is then a good candidate to use for the dual‐fuel concept since it has been proven to be a

Environmental impact evaluation of diesel engine fuelled with CNG [PDF]

Archives of Environmental Protection, 2023
The uncertainty in the supply of crude oil, increasing the number of vehicles and rising air pollution, especially in urban areas, has prompted us to look for alternative fuels. It is understood that using Compressed Natural Gas (CNG) in IC engines could

Effects of combining EGR and supercharging on the combustion characteristics of a diesel dual fuel engine with induced natural gas

Nihon Kikai Gakkai ronbunshu, 2018
This paper describes the results of a combination of EGR and supercharging applied to a diesel dual fuel (DDF) engine using natural gas (CNG) introduced from an intake pipe. The oxygen concentration in the intake charge were varied from 21% (without EGR)
