Abstract
The paper addresses two important issues in the design and operation of liquid LPG (Liquid Petroleum Gas) port injected engines: unacceptable HC (hydrocarbon) emission during cold starts and long hot start times. The poor cold start performance of these vehicles has been traced to deposits forming within the fuel injectors. The long hot start times have been attributed to vaporization of the fuel within the fuel rail during hot soak. The experimental research into solutions for both of these problems is reported in the paper.
