This increases flexibility in terms of engine design, promotes lower exhaust and fuel consumption levels, and results in even quieter operation. Combined with exhaust gas recirculation and SCR systems, Bosch high-pressure injection systems make a significant contribution to reducing fuel consumption and nitrogen oxides.

These researchers have investigated this mode of combustion—PREmixed Mixture Ignition in the End-gas Region (PREMIER)—in previous studies with natural gas. Because of mixture autoignition in the end-gas region ahead of the propagating flame front, a transition occurs resulting in a rapid increase in the heat release rate.
