Abstract

Two important issues for liquid LPG or propane PFI engines were shed unacceptable HC emissions during cold starts and long hot start times. The poor cold start performance was linked to deposits forming within the fuel injectors and the long hot start times were due to the vapourization of the fuel within the fuel rail during hot soak and hot start. Solutions for both of these problems were developed. To determine the effects of fuel composition on the formation of deposits, 5 sets of fuel injectors were mileage-accumulated on road for 6400 km with 40 hot soaks using identical vehicles operating with fuels of different compositions or different injector designs. Each set of mileage-accumulated injectors was installed in a test vehicle and standard FTP emission tests were performed on a vehicle chassis dynamometer using a standard fuel.
