TL;DR: In this paper, the effect of injecting assistance gases (air and N 2 ) on the combustion characteristics of a single-cylinder methane spark ignition engine was investigated, and the results showed that the assistance gas injection at 70 crank angle degree (CAD) before top dead center (BTDC) increased the combustion speed and the indicated mean effective pressure (IMEP) because the gas jet induced strong turbulent flow within the cylinder.

Effect of ammonia addition on combustion and emission characteristics of hydrogen-fueled engine under lean-burn condition
TL;DR: In this paper , the authors investigated the suppression of the heat release rate (HRR) of a hydrogen-fueled engine through the addition of ammonia (NH 3 ), and the results showed that small amounts of ammonia reduced the combustion rate of the fuel mixture, prolonged the flame development period (CA0-10) and propagation durations (CA10-90), and reduced the peak in-cylinder pressure and peak HRR under lean-burn conditions.

Effect of hydrogen direct injection on natural gas/hydrogen engine performance under high compression-ratio conditions
TL;DR: In this article , the inner mechanism of hydrogen direct injection on methane combustion was optically studied based on a dual-fuel supply system, and the results showed that lean combustion can improve methane engine's thermal efficiency, but is limited by cyclic variations under high excess air coefficient conditions.
