Investigation of Main Injection Quantity Fluctuation due to Pilot Injection in High Pressure Common Rail Fuel Injection System
High pressure common rail (HPCR) fuel injection system is the main development trend for fuel injection system of diesel engine. Precise controlling of injection pressure and multiple injections are the advantages and key features of the HPCR system. Affect of pilot injection quantity (PIQ) and pilot-main interval (PMI) on main injection quantity fluctuation (MIQF) has been investigated in this...
متن کاملNumerical and experimental investigation of common rail fuel injection system and evaluating influence of fuel pressure on injection characteristics and pressure fluctuations
The combustion processes, engine performance, fuel consumption, exhaust-gas composition, and combustion noise in the diesel engine are closely linked to appropriate mixture of air-fuel in combustion chamber. The fuel-injection parameters such as injection start point, discharge rate curve, injection time and injection pressure are defined by the quality of the mixture formation. The numerical m...
متن کاملESO-based iPI Common Rail Pressure Control of High Pressure Common Rail Injection System
This paper presents an ESO-based iPI control for common rail pressure. First, a detailed mathematical model of High Pressure Common Rail Injection System (HPCRIS) is built. The mathematical model is validated by the software Matlab and commercial software AMESim. For the considered HPCRIS, an effective model free controller which is called Extended State Observer based intelligent Proportional ...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Numerical investigation the effect of accumulator on reducing the pressure waves in a common rail fuel injection system of diesel engine
Pressure fluctuations during fuel injection are one of the factors that negative effect on performance of diesel engine. These fluctuations are caused by the rapid opening and closing of the nozzles and the creation of pressure waves in the fuel rail. One way to control these pressure fluctuations is to change the injector design and use an accumulator in the injector. This study is performed t...
