THE AUTOMATIC CONTROL SYSTEM FOR OPERATION OF PETROL INJECTION ENGINE AT IDLE APEED MODE

The purpose of research is improving the petrol fuel injected (injector) motor vehicles in mode independent of idling by the fuel-air mixture composition control adjustment by an automated control system that provides reconfiguration (reprogramming) of standard motor controller for the air / fuel mixture corresponding to the specified high-speed idling. The article is devoted to solving problems related to the operation of the engine with injected fuel at low rpm model of independent mode is idle (at stops and Parking of motor vehicles with the engine running) that is due to poor mixture formation is characterized by impaired flow of operating the process of the cylinders. Developed a new way of working gasoline engine with fuel mode injection independent of idling and automated system for its implementation, allowing the air / fuel mixture adjusting through the regular reprogramming the engine control module on the air-fuel mixture corresponding to the specified high-speed idling. The advantage of this system is the compactness, wide availability of components and the ability to quickly connect to the circuit established to the engine controller. Studies show that the use of the automated system control the operation of a fuel injected engine in a mode independent of idling allows to reduce the minimum stable engine speed is up to 300-600 min-1, the operational fuel consumption by 15-20%, the content of harmful substances in exhaust gases by 30-60% compared to engine operation in normal configuration
