Suzuki BURGMAN AN650 (2003) [171/463] Compensation of injection time volume

Содержание

6 10 Fl SYSTEM CVT SYSTEM COMPENSATION OF INJECTION TIME VOLUME The following different signals are output from the respective sensors for compensation of the fuel injection time volume SIGNAL ATMOSPHERIC PRESSURE SENSOR SIGNAL ENGINE COOLANT TEMPERATURE SEN SOR SIGNAL INTAKE AIR TEMPERATURE SENSOR SIGNAL HEATED OXYGEN SENSOR SIGNAL E 02 19 BATTERY VOLTAGE SIGNAL ENGINE RPM SIGNAL STARTING SIGNAL ACCELERATION SIGNAL DECELERATION SIGNAL DESCRIPTION When atmospheric pressure is low the sensor sends the signal to the ECM and reduce the injection time volume When engine coolant temperature is low injection time vol ume is increased When intake air temperature is low injection time volume is increased Air fuel ratio is compensated to the theoretical ratio from density of oxygen in exhaust gasses The compensation occurs in such a way that more fuel is supplied if detected air fuel ratio is lean and less fuel is supplied if it is rich ECM operates on the battery voltage and at the same time it monitors the voltage signal for compensation of the fuel injection time volume A longer injection time is needed to adjust injection volume in the case of low voltage At high speed the injection time volume is increased When starting engine additional fuel is injected during cranking engine During acceleration the fuel injection time volume is increased in accordance with the throttle opening speed and engine rpm During deceleration the fuel injection time volume is decreased INJECTION STOP CONTROL SIGNAL TIP OVER SENSOR SIGNAL FUEL SHUT OFF OVER REV LIMITER SIGNAL DESCRIPTION When the motorcycle tips over the tip over sensor sends a signal to the ECM Then this signal cuts OFF current sup plied to the fuel pump fuel injectors and ignition coils The fuel injectors stop operation when engine rpm reaches rev limit rpm
