摘要：Carbureted 2-stroke engines are a worldwid e pandemic. There are over 50 million 2 -stroke cycle engines in Asia alone, powering motorbikes, mopeds, "three-wheelers", "aut o-rickshaws", "tuk-tuks", and "tricycles". These carbureted 2 -stroke engines are characterized by high levels of hydrocarbon (HC), carbon monoxide (CO), and particulate matter (PM) emissions. Direct injection is a technology that has shown a great ability to reduce these emissions while at the same time improve fuel economy. A prototype kit has been designed for use in retrofitting existi0ng carbureted two -stroke engines to direct injection An external compressor was added to supply compressed air to the system. The carburettor was refined with a throttle body outfitted with a position indicator, and an encoder system was added to provide speed and position feedback to the engine control unit (ECU). Once design and manufacture of the system was complete, it was installed on the motorcycle the system was also tuned in real world road tests for drivability. When calibrations were complete emissions and fuel consumption measurements were taken for the vehicle .It has been performed on a Yamaha rx135.
