DEVELOPMENT OF A NEW TYPE CYLINDER HEAD FOR PISTON COMPRESSORS

摘要

The main purpose of the present work is to show the influence of a developed cylinder head on the free run performance characteristics of the piston compressors used in the brake systems of the heavy vehicles. When the discharge chamber pressure reaches to the desired value, the compressor delivers the air to the atmosphere through the suction or discharge port of conventional cylinder heads. In the developed system, the pressurized air is used to recuperate the energy taken from the vehicle engine. Therefore, less energy is consumed compared to that for conventional types of cylinder heads. Effects of three different cylinder heads on the performance of piston compressor in the free run mode are studied experimentally. The detailed cylinder pressure and torque measurements are used to explain the low energy consumption.
