WebbIn the case of pink discharge, it can be said that it is normal as long as it occurs in the following stages: when you are ovulating, if you are pregnant or if your period has just ended. In these three reasons, the pink discharge is considered normal, although not all women present it in one of these stages. Knock occurs when the peak of the combustion process no longer occurs at the optimum moment for the four-stroke cycle. The shock wave creates the characteristic metallic "pinging" sound, and cylinder pressure increases dramatically. Effects of engine knocking range from inconsequential to … Visa mer In spark ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the … Visa mer Due to the large variation in fuel quality, atmospheric pressure and ambient temperature as well as the possibility of a malfunction, every modern combustion engine contains mechanisms to detect and prevent knocking.

Webb25 nov. 2024 · Ping is a knocking noise that can indicate a problem with the engine. It is usually caused by a build-up of deposits on the piston or in the cylinder, which can cause the engine to run less efficiently. Other potential causes include a lean fuel mixture, incorrect ignition timing, or a problem with the carburetor. WebbIn an SI engine, knocking occurs after the mixture is ignited by the spark plug. In a CI engine, knocking occurs at starting of the combustion process. 2] Knocking causes due to low ignition lag.
