가솔린 기관 연료 펌프 계통의 유량·압력 특성

다국어 초록 (Multilingual Abstract)

In this study, the flow and pressure pulsation in a high pressure fuel pump for gasoline engine is investigated. The pump changes a low pressure flow supplied from fuel transfer pump to high pressure flow in order to improve the engine efficiency. The pump supplies a high pressure fuel to common rail. It is the core part in the fuel supply system. It is essential to have a excellent durability because it should be operated in poor working condition. Pulsation and vibration is related on the pump durability. In this study, the author analyzes the operating principle of this pump and performs the experiment focusing on pulsation. The characteristics of the fuel pump is investigated and a reliable simulation model is developed by AMESim software. The simulation model is verified by comparing simulation results with experiments.
