Abstract

TO ENABLE CALCULATION OF FUEL INJECTION AMOUNT BY DETECTING INTAKE AIR MASS WITHOUT USING AN AIR FLOWMETER. A COMPRESSION AND EXHAUST TIME CALCULATING SECTION 3 RESPECTIVELY CALCULATES COMPRESSION STROKE START AND END TIMES TC1 AND TC2 AND EXHAUST STROKE START AND END TIMES TEL, TE2 BASED ON THE PERIOD OF CRANK PULSES GENERATED BY A CRANK ANGLE SENSOR (2). AN INTAKE AIR MASS CALCULATING SECTION 4 (104) CALCULATES INTAKE AIR MASS USING EQUATION AS "INTAKE AIR MASS OC [{ (1/TC1) 2-(1/TC2) 2}_{ (1/TE1) 2-(1/TE2) 2}]". CALCULATED INTAKE AIR MASS IS INPUT TO A FUEL INJECTION AMOUNT CALCULATING SECTION 5 (105), WHICH CALCULATES FUEL INJECTION AMOUNT CORRESPONDING TO INTAKE AIR MASS ACCORDING TO A TARGET RATIO OF AIR TO FUEL. A FUEL INJECTION VALVE (16) IS DRIVEN AT A DUTY CYCLE DETERMINED ACCORDING TO THE CALCULATED FUEL INJECTION AMOUNT, TO SUPPLY AN APPROPRIATE AMOUNT OF FUEL TO THE ENGINE 1.
