Experimental Study on An In -vehicle Compressed Air Supply System for the Diesel Engine
Abstract：When public traffic bus equipped with the turbocharged diesel is going to start or ac- celerate, exhaust emission increases due to low engine speed and delayed turbocharger response. In order to solve this problem, a compressed air supply system is developed. While the engine speed is idle or reduces, the auxiliary air compressor is used to charge air into the gas - tank with higher pressure. When the engine is accelerated, the compressed air in the gas -tank with lower pressure is injected directly into the intake pipe through a solenoid valve operated by an electronically con- trolled unit so that the cylinder charge increases. The in - vehicle experiment results show that prac- tical application is much satisfactory due to usage of this system and smoke emission is lower while the diesel engine is accelerating.
