Cross baffle built-in constant volume combustion chamber employing gasoline as fuel

Abstract

The invention relates to an internal fixed-cubage combustor, which adapts gasonline as fuel, belonging to the combustor burning area, mainly comprising body (1), diaphragm, front end cover (24), back end cover (27) and visual window (25) so on. The figure of body is cuboid. The inside is the space with cuboid in the middle and semi-circular structures at two ends. There are N pairs of transversal slots on the inner wall of body (1) and the diaphragm is set into one pair of transversal slot. There are holes on the diaphragm. The diaphragm divides the inner space of body (1) into upper and lower parts. There is a spark plug (14) at the center position of upper part and there is an air pressure sensor (10) at the center position of lower part. The invention adopts the internal diaphragm to divide a uniform combustor into upper and lower combustors. The upper combustor (49) is used for the burning study of spark ignition and the lower combustor (50) is used for the burning study of compression ignition or pilot ignition.

Description

technical field [0001] The invention relates to a built-in diaphragm constant volume combustion chamber (CVCC) using gasoline as fuel, which is mainly used for analyzing various factors affecting gasoline constant volume combustion, and then optimizing the performance of a gasoline engine in practical application, belonging to The field of internal combustion engine combustion, specifically the research field of gasoline / air mixture combustion. Background technique [0002] Existing devices at home and abroad to study gasoline constant volume combustion are constant volume combustion chambers or constant volume incendiary bombs. The main structure of the existing constant volume combustion chamber or constant volume incendiary bomb is a closed uniform space in the shape of a sphere, a barrel, or a cube, and gasoline and air are mixed and burned in this space. The main disadvantages of the existing constant volume combustion chamber are: (1) the combustion chamber is a unifi...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defect that the existing constant volume combustion chamber cannot be used for compression ignition combustion and pilot combustion research, and propose a built-in diaphragm constant volume combustion chamber using gasoline as fuel. The diaphragm divides a unified combustion chamber into an upper combustion chamber and a lower combustion chamber. The upper combustion chamber is used for spark ignition combustion research, and the lower combustion chamber is used for compression ignition combustion or pilot combustion research.
