A Study of the Combustion Completion on the 2-Stroke HCCI Engine with n-Butane/air Mixture - Investigation of the Composition and the Exhaust Mechanism of the Exhaust Gas -

The exhaust gas composition was analyzed by gas chromatography, and combustion completion was investigated in a 2-stroke Homogeneous Charge Compression Ignition (HCCI) engine. The experiment was performed using n-Butane as a typical pure fuel to easily identify the origin of exhaust gas components. The effect of maximum gas temperature on combustion completion was investigated by both the experiment and the calculation. From the measurements of unburned n-Butane emission, the thickness of the quenching layer was estimated.
