Abstract: A method for diagnosing cold start strategy monitoring of a vehicle is provided to improve the marketability of a vehicle by satisfying OBD-II without additionally installing hardware. A method for diagnosing cold start strategy monitoring of a vehicle comprises a step of determining if state information detected when a vehicle starts satisfies a catalyst heating function(S103). If the state information satisfies the catalyst heating function, an engine RPM is added up during the catalyst heating function(S106). If the catalyst heating function has been completed, a diagnosis mode for cold start strategy monitoring is performed(S108). The added engine RPM is compared with an engine RPM addition value mapped with a reference value(S110). If the added engine RPM is smaller than the engine RPM addition value mapped with the reference value, an error code is output by determining that the cold start strategy monitoring is abnormally performed(S114).

Abstract: PURPOSE: A method for calculating an amount of injection fuel is provided to improve the safety of an engine by preventing the great amount of air to suddenly flow into a cylinder of the engine. CONSTITUTION: A control section detects pressure information in surge tank by analyzing signals applied from a negative pressure detecting section(S101). Then, the control section analyzes negative pressure information based on data set in a memory section and converts negative pressure information into an amount of air(S102). The control section determines whether the amount of air introduced through a throttle valve is identical to the amount of air introduced into each cylinder(S103). If the amount of air is different from each other, the variation rate of the throttle valve is measured(S104). Then, the control section predicts the amount of air to be compensated(S106), and calculates the amount of fuel to be injected into the cylinder. Then, the driving time of the injector is determined(S107), and the injection of fuel is carried out(S108).
