Multi-dimensional adjustable combustion chamber testing device based on constant volume bomb

Abstract

The invention provides a multi-dimensional adjustable combustion chamber test device based on a constant volume bomb, and belongs to the field of basic test research of internal combustion engines. The problems that in the prior art, the position and angle of a simulation combustion chamber cannot be adjusted in a constant volume bomb, and different test variable conditions cannot be met are solved. The device comprises a constant volume bomb, a combustion chamber, a nozzle and an oil sprayer, the combustion chamber is a multi-dimensional adjusting combustion chamber, the constant volume bomb comprises a plurality of constant volume bomb side covers, the combustion chamber is located in the constant volume bomb and installed on one of the constant volume bomb side covers, and the oil sprayer is installed on the constant volume bomb side cover opposite to the combustion chamber. And the nozzle is communicated with the oil sprayer. The depth of the slice combustion chamber in the constant volume bomb is mainly adjusted by taking the X-axis sliding rail as a reference, and the height of the slice combustion chamber in the constant volume bomb can be mainly adjusted by the Y-axis sliding rail, so that the requirements of different fuel injector assembly positions are met.
