Study and Improvement A Box Control Engine Piston One System Injection for use Gasohol E85 as Fuel

Abstract

The objective of this research was to study the modification of the injection control system and performance tests of motorcycle engine to use gasohol E85. The injection control system is Programmed Fuel Injection (PGM FI).This research has designed the new fuel injection system used in conjunction with the ECM of the motorcycle. The final results showed that the engine power using gasohol E85 was same as gasoline. But the rate of fuel consumption and higher pollution output will be lower than gasoline engines. However the modification of engine needed to compensate the lower energy content of ethanol in gasohol E85 and avoid problem of cold start due to its lower vapor pressure. This can be concluded that gasohol E85 have a good tendency to be used as alternative fuel. It give higher thermal efficiency than gasoline while more than brake specific fuel consumption due to the lower heating value of ethanol.
