| Abstract: | Natural gas is very different from liquid fuels, such as gasoline and diesel fuel, in ignition characteristics, mixture formation process, combustion speed and so on. These characteristics greatly influence the cycle variation in the engine. The influence on lean-burn combustion is larger than that on stoichiometric combustion and the influence has not yet been sufficiently studied. In this paper, several factors for the stabilization of combustion of spark ignition natural gas lean-burn engines are clarified by means of experimental investigations using such parameters as ignition condition, swirl and compression ratio. |
