Fuel Injection of a Two-Stroke Cycle Spark Ignition Engine 820952

A study of fuel injection during the open cycle of a small spark ignition two-stroke cycle engine has been carried out. A manually controlled electronic fuel injection system has been used as this appears to have many advantages over mechanically controlled equipment. Various injection locations were considered and injection timing and air/fuel ratio varied at each position to determine optimum power and bsfc requirements. The results presented are compared with baseline carburation and with fuel injection into the intake to assess the potential improvements gained from each injector location.
