인테이크 매니폴드 러너 길이, 부피, 캠 프로파일, 압축비 등이 엔진의 파워 커브에 어떤 영향을 미치는지 이해하고 싶음
처리 내용
인테이크 매니폴드 러너 길이는 실린더 헤드의 흡입 포트 페이스에서 모든 실린더가 공유하는 공통점(스로틀 바디가 있는 플레넘 또는 개방 대기)까지의 직선 거리입니다. 인테이크 러너 부피는 이 흡입 시스템 구간의 부피, 즉 단면적에 길이를 곱한 값입니다. 짧고 넓은 흡입 러너는 토크 커브를 고회전 영역으로 이동시키고, 길고 좁은 러너는 저회전 영역으로 이동시킵니다. 이 효과는 러너 내의 상대적으로 높고 낮은 압력의 펄스 웨이브(압력파)에 의해 발생합니다. 흡입 밸브가 열리면 엔진 측 러너에 저압이 생기고, 공기가 러너를 통해 실린더로 흘러들어갑니다. 밸브가 닫힐 때 그 공기의 흐름이 멈추면서 압력파가 발생하여 파워 커브 특성에 영향을 미칩니다.

BMW M5
I started this thread really with a question about pros and cons of putting an AJP or something else in my scrap Cerbera and it has morphed into a project build thread over time. Brief history:I was thinking about buying myself a fun sports car, there's nothing new in the £50-80k range I would particularly be interested in. Had to feel special, had to be light, "analogue" and not overly-assisted. Had to be manual and i prefer a large capacity NA to forced induction. Ford Mustang maybe, perhaps not quite special enough and a bit porky. Emira - I love Lotus and have had a few but i'm not a fan o
BMW X5
After writing off my BMW 320d halfway through the month, I suddenly found myself in the market for a new car.Once the insurance payout landed, I had just under £5,500 to play with after paying my excess. I spent hours trawling AutoTrader trying to find the right replacement.I'd lined up a BMW X5 that was slightly over budget and was due to view it today... only for it to sell yesterday before I got the chance. Frustrating, but that's just how it goes.I kept looking, but nothing else really grabbed me.Then I spotted a Range Rover Sport on AutoTrader just five miles away. I called the dealership
