Abstract

본 발명은 엔진의 과도 상태에서 흡기 포트의 벽류량을 측정할 수 있는 흡기 포트의 벽류량 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring an amount of wall flow of an intake port capable of measuring an amount of wall flow of an intake port in a transient state of an engine.

측정하고자 하는 실린더 헤드(30)와, 상기 실린더 헤드(30)에 연료를 공급하기 위한 연료 공급 장치(20)와, 실린더 본체 대용으로서 실린더 헤드(30)의 하부에 체결되는 유량 측정 장치(40)로 구성된다.A fuel supply device 20 for supplying fuel to the cylinder head 30 and a flow rate measuring device 40 which is fastened to the lower portion of the cylinder head 30 as a substitute for the cylinder body, .

이와 같이, 과도 상태에서 실린더로 흘러 들어가지 않고 흡기 포트의 백면에 남아있는 연료의 벽류량을 측정할 수 있기 때문에 상기 벽류량을 최소화하기 위한 인젝터의 분사 위치, 분사 방향 및 분사 각도를 개선하여 엔진의 성능을 향상시킬 수 있다는 효과가 있다.Since the wall flow amount of the fuel remaining on the white surface of the intake port can be measured without flowing into the cylinder in the transient state in the transient state, the injection position, injection direction and injection angle of the injector for minimizing the wall flow amount can be improved, It is possible to improve the performance of the apparatus.
