Abstract: A method for controlling abnormal signal of a throttle position sensor is provided to determine abnormal signal of the throttle position sensor and maintain a proper air-fuel ratio, thus ensuring the normal combustion of engine. A method for controlling abnormal signal of a throttle position sensor comprises a step of determining whether the throttle position sensor generates abnormal signal when a fault code of the throttle position sensor is not generated(S301,S305); and a step of determining an injection time through the throttle position sensor based on the fuel supply amount except for fuel compensation amount when the throttle position sensor generates the abnormal signal while determining an injection time through the throttle position sensor based on the fuel supply amount including fuel compensation amount when the throttle position sensor does not generate the abnormal signal(S307,S309). It is determined that the throttle position sensor generates abnormal signal when the signal change rate in the acceleration is greater than the maximum signal slope(DeltaP[+]) of the throttle position sensor in the acceleration.

Abstract: A fuel supply apparatus of an LPI(Liquefied Petroleum Injection) engine is provided to prevent excessive emission of hydro carbon during an early stage of engine start caused due to excessive fuel in a combustion chamber, by circulating fuel remaining in an injector to a fuel tank after stoppage of the engine. A fuel supply apparatus of an LPI engine, comprises a pressure regulator(100), a pulsation sound absorber(200), and a third cutoff valve(300). The pressure regulator is interposed between a fuel pump(2) of a fuel tank(1) and a first cutoff valve(3), and circulates fuel to the fuel tank if the supply pressure of the fuel pump is higher than a preset pressure level. The pulsation sound absorber is arranged at a fuel return line(7) of an injector(5), and removes pulsation sound generated during operation of the injector. The third cutoff valve prevents fuel from returning to the fuel tank during operation of the engine, and opens to allow fuel remaining in the injector to return to the fuel tank when the engine stops.
