DESIGN OF A CONSTANT VOLUME COMBUSTION CHAMBER WITH OPTICAL APPROACH TECHNIQUE

Abstract

The combustion process in the internal combustion engine is realized as the core of the engine's power and exhaust emission formation. This paper describes the design of a constant volume combustion chamber (CVCC) to simulate the combustion process of the diesel engine with the optical approach technique. The technical design standards of the chamber were based on the actual conditions of diesel engines with a compression ratio of 16 to 28 and an injection profile with a fuel pressure varying between 400 and 1600 bar. The system included 2 quartz crystal windows that allow observing the entire process of fuel injection and combustion taking place inside the chamber. The structural strength analysis of the design under simulating pressure was carried out by ANSYS software. The results revealed that the chamber met durable standards with each type of material based on design criteria with a pressure of 200 bar selected as the ambient pressure inside the chamber.
