Effect of pressure transducer position on measured cylinder pressure diagram of high speed diesel engines

摘要

The cylinder pressure diagram is a valuable source of information for reciprocating internal combustion engines. If processed, it provides information concerning the combustion process inside the engine cylinder. During this process, a problem that usually arises is the proper mounting of the press- ure sensor on the cylinder head. The optimum is to flush-mount the transducer to the cylinder head so that if can be directly in contact with the gas. Unfortunately, in many cases, and mainly in small size high speed commercial engines, this is not always possible.
