엔진을 retard(지연)한다는 것이 무엇을 의미하는가?
처리 내용
엔진의 Advanced(진각) 또는 Retard(지각) 조정은 스파크가 발생하는 시간을 약간 앞당기거나(진각) 또는 늦게(지각) 조정하는 것을 의미합니다. 일반적으로 점화 타이밍은 상사점(TDC)보다 약간 전에 스파크가 발생하도록 설정됩니다. 공기-연료 혼합기가 연소하고 팽창하는 데 시간이 걸리기 때문에, 혼합기가 TDC 직후에 완전히 연소되는 것이 이상적입니다. 스파크가 너무 일찍 발생하면 피스톤이 내려가기 시작하기 전에 팽창이 일어나 노킹이 발생하고 엔진 손상 가능성이 있습니다. 스파크가 너무 늦게 발생하면 피스톤이 이미 상당히 내려가 있어 출력 손실, 연비 악화, 과열 가능성이 발생합니다. 필요한 정확한 타이밍은 엔진 속도, 부하, 연료 옥탄가, 온도 등 여러 요소에 따라 달라집니다. 예를 들어, 엔진 속도가 빨라질수록 연료가 여전히 연소할 시간을 확보하기 위해 타이밍을 더 진각 조정해야 하며, 사이클은 짧아지지만

Collected this yesterday. I had been waiting for the right spec car since Christmas. I wanted; Clubsport pack, PDK, dual zone climate, either shark or gentian blue, yellow sticking, leather dash, sports chrono, rear camera, FPSH and Porsche warranty. Everything that came up matching that was either over budget, sold before it was advertised or sold the day it was advertised. I even lost out on a car to Jay Kay, cool story, bro. I left my details and requirements with the likes of RPM and JZM in the hope of a call before a car was advertised. There was some time pressure. I naively booked a tra
