Abstract

Since LPG has a higher octane number and a lower maximum combustion temperature than gasoline it is getting more popular for reducing emissions from the vehicle This paper when an LPG engine works in the range of idle analyzed the operating range preciously an provides reducing method of emissions for the LPG engine. An electronic control unit(ECU) for the LPG engine using a feedback mixer is presented. The ECU is built by using a microcontroller MC68HC05. A PI-controller is imple-mented in the ECU in order to handle to handle Air/Fuel ration control. The experimental results exhibit that the required engine performance are satisfied at idle.
