Analysis of Thermo-Mechanical Behaviour of Air Compressor in Automotive Braking System

Abstract—The modern automotive vehicles with air brake system and air assisted hydraulic brake system use reciprocating air compressor with disc, reed or ring valves. Automotive compressors are run by engine itself. Well designed compressor will consume less power and deliver maximum flow of air thereby reducing the power taken from the I.C. engine. This indirectly reduces the fuel consumption of engine and thereby pollution. The mathematical model will be an effective tool in compressor design and for analysing the thermo-mechanical behaviour of compressor in working condition. This paper aims at analysing the thermo-mechanical behaviour of the air compressor used in automotive braking system using compressor model developed with the help of fundamental equations and experimental results. Experiment results are obtained from a 160 cc air cooled compressor with 80 mm bore and 32 mm stroke to validate the developed model performance. The effect of operating parameters, like, discharge pressure, compressor speed, etc., on thermodynamic and mechanical behaviour of compressor such as cylinder pressure, cylinder volume, cylinder temperature, valve lift and resultant torque at different crank angles and free air delivered and indicated power of the compressor was analysed.

Index Terms—Volumetric efficiency, free air delivered, reed valve, peak pressure, valve lift.
