Mixed Gas Compression Combustion Test Device And Combustion Simulation

Engine is the power output device which is the biggest energy consumer, and also the largest client in consumption of the Petroleum Energy. Worldwide energy problem and the our country energy safety problem are big problem now. At the same time, the emission of engine caused great destruction, bringing the photochemical smog, acid rain and many other severe pollution, bringing indelible physical and psychological harm to many people. HCCI mode is different with the existing combustion mode. It has the advantages of high thermal efficiency, good fuel economy, low harmful emissions, and it is adapt to various types of fuel and other advantages. It meets the need of the energy problem and the environment problem.This article which as part of HCCI foundation research designed a HCCI test system. We designed a test device which can simulation the combustion part of HCCI engine. This test device consists of the cylinder compression device, the excessive transmission device, a power cylinder, the bench and the air compressor. This paper introduces the designed and built process of the test system. Depend on this HCCI test system, we studied how to accurately control the mixture combustion on different fuel, compression ratio and temperature. We observed the fuel combustion status about different fuel, initial compression temperature and compression ratio. According to the obtained actual combustion status we analysis the characteristics of various fuel and the requirements for the engine. And this paper introduced the use of the test system HCCI test research process and our experience. This paper also uses CHEMKIN to simulation the HCCI engine.
