Efficient light-duty engine using turbulent jet ignition of lean methane mixtures [PDF]

International Journal of Engine Research, 2019
Diesel engines use diffusion-controlled combustion of a high-reactivity fuel and offer high efficiencies because they combine lean combustion with a high compression ratio. For low-reactivity fuels such as gasoline or natural gas, premixed combustion is used, which leads to lower efficiency levels as usually stoichiometric combustion is combined with ...
