유량 제어 밸브 방식이 dme 고압 연료 펌프의 성능에 미치는 영향

TLDR: In this article, the effect of flow control valve type on the performance of wobble plate type fuel pump for the stable DME fuel supply was described, and different four flow control valves (ITV, SCV, IMV and MPROP) were installed on the fuel pump, and fuel flow rate, torque and temperature variation of pump were investigated under various operating conditions by using pump performance test system.

Abstract: This experimental work described the effect of flow control valve type on the performance of wobble plate type fuel pump for the stable DME fuel supply. In order to study this, different four types of flow control valves (ITV, SCV, IMV and MPROP) were installed on the wobble plate fuel pump, and fuel flow rate, torque, and temperature variation of pump were investigated under various operating conditions by using pump performance test system. It was revealed that wobble plate type fuel pump worked well with ITV and SCV control valve, and the flow rate and torque of fuel pump was in proportion to the value of valve open duty. The maximum flow rate and torque of fuel pump were achieved around the 50% duty of control valve. Temperature variation at all pump measuring points were under 60℃ which is acceptable.
