碩士 === 逢甲大學 === 材料與製造工程所 === 100 === In this study, a small SI engine (Mitsubishi EY20D) is analyzed theoretically and select a small turbocharger (Hitachi HT06) for matching. The intake and exhaust pipe is designed, and the fuel mixture ratio, ignition timing and valve clearance are adjusted to complete the experimental equipment of a suck-through small carburetor gasoline single-cylinder turbocharged engine. The Nm and Brake Horse Power (BHP) are obtained by electric-dynamometer. The bsfc is determined in a fixed speed by the fuel consumption measurements. The CO (in %) and HC (in ppm) are determined by non-dispersive exhaust gas analyzer. The above experiments are recorded in tables, and the experiment steps are repeated to be compared with naturally aspirated engine and turbochargered for analyses and discussions. The technology of the small turbocharger SI engine is expected to be more advanced by means of the research.
