METHOD FOR ACTIVATING FUEL SUPPLY SYSTEM OF INTERNAL COMBUSTION ENGINE OF VEHICLE, FUEL SUPPLY SYSTEM FOR INTERNAL COMBUSTION ENGINE OF VEHICLE, AND CONTROL ELEMENT FOR CONTROLLER OF INTERNAL COMBUSTION ENGINE OF VEHICLE

摘要

PROBLEM TO BE SOLVED: To identify an increase in toxic substance discharge based on obtained fuel amount, by checking whether or not combustion has occurred in the cylinders and obtaining the fuel amount supplied to the cylinder in which combustion has not occurred.;SOLUTION: A fuel amount M which should be injected into each cylinder of an internal combustion engine is obtained (S21) and the total sum of the fuel amount M injected into each cylinder is also obtained (S22). A check is then done to confirm whether the fuel amount injected into the ignited in each cylinder has actually combusted (S23). If combustion is found not to have occurred in the cylinder, the fuel amount M injected first is led as unburned fuel amount Munverbrannt and summed up. Only a portion of the total unburned fuel Munverbrannt reaches the exhaust pipe. This component MAhgasroht of the total unburned fuel Munverbrannt that reached the exhaust pipe is obtained by a weighting factor a that relies on the engine temperature (S24).;COPYRIGHT: (C)2000,JPO
