| Research Abstract |
Gas fuels generated from biomass resources have been applied to an HCCI engine (Homogeneous Charge Compression Ignition) to achieve higher thermal efficiency. The difficulty is that the gas fuels have the variation of its composition and the ignition and combustion of HCCI largely depends on the chemical reaction. Then, in-situ sensing method of ignition and combustion was studied and control algorithms were developed. For the fuel composition change in the order of minutes, the engine control system achieved stable operation and higher thermal efficiency.
