臺灣博碩士論文加值系統

本實驗利用8051微電腦單晶片作為汽油噴射系統的ECU，以HONDA GX-270化油氣引擎為本體，改變進氣系統，並製作專用供油電腦，透過不同轉速與不同節氣門開度之噴油脈寬的調整，改善並增加引擎之馬力與扭力。
近年來電子產業的快速發展使單晶片成本降低，穩定性提高，本實驗用之單晶片擁有ISP功能，透過ISP可直接修改系統參數，運用於Go-Kart分秒必爭的比賽上，將得到更佳的即時效能。
實際測試本噴射引擎於油門開度85%所表現之性能已與化油器相當，油門全開狀態下之馬力更提升到7 kW，性能提升約12%。

In this study, using a 8051 microprocessor to make an ECU with an electronic fuel injection, we use a HONDA GX-270 gasoline engine. The carburetor system was replaced with a fuel injection system. A special purpose ECU was made to control the injection duration based on the engine’s rotational speed, and throttle angle in order to improve and increase the horsepower and torsion of the engine.
Given the fast development of the electronics industry the cost of single chips have reduced in recent years with increasing chip stability. The microprocessor used in this study has ISP function; it can revise systematic parameters directly through ISP. As a result, when used in application for Go-Kart racing, there is better instant efficiency.
The fuel injection system has already equal performance to a carburetor system engine with a 85% throttle angle. With it’s throttle angle at 100%, the engine has a horsepower 7 kW, with a performance improvement at about 12% in comparison to a carburetor one.
