PROPOSED METHOD TO ACQUIRE AN EXTENDED DIAGRAM FOR A GASOLINE ENGINE

Abstract

This paper presents a noninvasive method to obtain an extended diagram for a single cylinder four-strike cycle engine. In order to draw such a diagram we designed and built an experimental test bench. In the first part of this paper we described how one can make a piezoelectric pressure transducer that allows measuring the pressure within the internal combustion engine cylinder. We also drew the extended diagram for the single cylinder four-stroke engine using the aforementioned software. The diagrams that were obtained by means of experiment allow us to perform studies on how the motive fluid behaves inside the engine cylinder. This is achieved by studying the shape of the drawn curves, the process duration compared to the duration of the processes obtained by calculus, functionality anomalies or parameter variation laws.
