Abstract:
At present, some of the changes of global climates, power crisis, environmental pollution, noises and fuel consumptions are caused by fuel and fuel injector. Therefore, biodiesel has been introduced to overcome the above problems. In this paper, we design a piezoelectric fuel injector for biodiesel injection using analysis of spray pattern and ignition time, and control of corrosion in diesel engine. In IC engines, noises, emission and fuel consumptions can be decreased and process of diesel injections is controlled directly by using the piezoelectric fuel injector. The fuel has not been mixed entirely in the process of conservative piezoelectric fuel injectors. Hence, the some modifications are made by us in piezoelectric fuel injector design for biodiesel injections. The piezoelectric fuel injector is designed in three phases that are piezo actuator with self sensing control model, the thermal compensator and the body of valve to improve the work of fuel injector that can be used to reduce the fuel consumption. The computational fluid dynamics (CFD) and Reliability Centered Maintenance (RCM) methods are combined to analyze the spray pattern for reduction of ignition time delay. This kind of spray pattern analysis used to improve the accuracy and to reduce the complex operation during the injections of biodiesel in fuel injector. CFD method can use the numerical analysis to find the problem of functions of location of fuel injector, spark plug, valve body, four strokes and
