Fabrication of Fuel Injector testing equipment

Abstract

Fuel injection is a technology used in internal combustion engines to mix the fuel with air prior to combustion. As in a traditional carburetor, fuel is converted to a fine spray and mixed with air. However, where a traditional carburetor forces the incoming air through a venturi to pull the fuel into the air stream, a fuel injection system forces the fuel through nozzle under pressure to inject the fuel into the air stream without requiring a venturi. The modern electronic systems that cars are equipped with today utilize a number of sensors to monitor engine conditions, and an electronic control unit (ECU) to accurately calculate the needed amount of fuel. Thus fuel injection can increase fuel efficiency and reduce pollution.
