FUEL CONTROLLER FOR INTERNAL-COMBUSTION ENGINE

摘要

PURPOSE:To improve the fuel economy of engine and operationability by providing a flow measuring resistor and a temperature compensating resistor then correcting the ratio between the differential temperatures of flow measuring resistor and fuel measuring resistor to low level under specific conditions. CONSTITUTION:A flow speed detecting resistor 73A having temperature dependent resistance and a temperature compensation resistor 73B are arranged at each side of Wheatstone bridge. It is corrected such that the ratio DELTATa/DELTATf will decrease as the fluid temperature increases, where DELTATa is the differential temperature between an air flow measuring resistor 73A while DELTATf is the differential temperature between a fuel flow measuring resistor 73A and temperature compensation resistor 73B. Consequently, the supply fuel flow accuracy can be improved resulting in improvement of engine fuel economy and operationability.
