There was a conflict between NOx emission and engine power of modified natural gas engine. Influence facters of NOx emission and emission characteristics of existing modified engine were studied. Emission and engine power of natural gas engine modified from gasoline and diesel engine were compared. Then some sugesstion are brought out for designing low NOx emission natural gas engine and promote engine power.

Parameters of natural gas engines were calculated with the aim to determine the optimal way of their working process organization. Analysis of calculations results demonstrated that quality power level control ensured the improvement of parameters of investigated engines. Calculations showed that compared with the diesel engine, the gas engine with quantity power level control, internal mixture formation and glow plug ignition of the gas-air mixture ensured the decrease of СО2 emissions by 26.8%, and the natural gas engine with quality power level control, external mixture formation and gas-air mixture ignition by a small pilot portion of fine atomized diesel fuel supplied by a Common Rail fuel system – by 25.5%. Therefore, one can choose one or another method of diesel engine conversion for operation on gas fuel considering available technical opportunities and with minimal expenses.
