TL;DR: In this article, a stoichiometric methane-hydrogen-air freely propagated laminar premixed flames at normal temperature and pressure were calculated by using PREMIX code of CHEMKIN II program with GRI-Mech 3.0 mechanism.

TL;DR: In this article, the authors investigated the combustion characteristics of a direct-injection spark-ignited engine fueled with natural gas-hydrogen blends under various ignition timings and lean mixture condition.

TL;DR: In this article, a direct injection engine operating on various fractions of natural gas-hydrogen blends was investigated and the results showed that the brake effective thermal efficiency increased with the increase of hydrogen fraction at low and medium engine loads and high thermal efficiency was maintained at the high engine load.

TL;DR: In this article, the combustion characteristics of a direct-injection natural gas engine under various fuel injection timings were investigated and the results showed that fuel injection timing had a large influence on the engine performance, combustion and emissions and these influences became largely in the case of late injection.

TL;DR: In this paper, the effect of hydrogen addition on cycle-by-cycle variations of a spark ignition engine fueled with natural gas-hydrogen blends with hydrogen volumetric fraction of 0, 12, 23, 30% and 40% was analyzed.
