Is 8 Cylinder Pressure Normal?

[VanEthan]

An 8-cylinder pressure is considered normal for a car, and for a 4-cylinder engine, a pressure of no less than 7 is within the normal range. Not every engine has the same cylinder pressure; Japanese cars typically have around 1100 KPa, while European and American cars range around 1200-1300 KPa. Modern direct injection engines tend to have even higher pressures. More details about car cylinder pressure are as follows: 1. The cylinder pressure data varies by vehicle model. Generally, large vehicles (such as Dongfeng 140 and Jiefang 141) have pressures between 6-8 kg, while small cars are normal above 8 kg. If the pressure is below the normal range, it can indicate an engine fault. 2. Since different cars and models have varying cylinder bores and strokes, this data also differs. The simplest way to check cylinder pressure is to ensure that all four cylinders have the same pressure. If one cylinder's pressure differs from the others, it means that cylinder is not functioning properly.
