Abstract: PURPOSE: A pre-ignition detecting apparatus and a high performance engine operation method using the same are provided to optimize all the operation ranges of an engine by calculating a pre-ignition starting point based on measured enthalpy value. CONSTITUTION: A pre-ignition detecting apparatus comprises an enthalpy sensor (21) and an engine control unit (ECU) (30). The enthalpy sensor is installed in a combustion chamber of an engine with a spark plug (3) to detect the enthalpy of the combustion chamber. The ECU has a logic to determine whether or not the pre-ignition of the combustion chamber is generated based on the enthalpy of the combustion chamber.

Abstract: The present invention discloses an apparatus for estimating the temperature of exhaust gas from a vehicle, which detects the surface temperature of an exhaust system component in a non-contact method and accurately estimates the temperature of exhaust gas from the surface temperature of the exhaust system component. The apparatus for estimating the temperature of exhaust gas from a vehicle comprises an engine which generates power by combusting air and fuel at a mixing ratio and discharges exhaust gas at a high temperature; a non-contact sensor which includes an exhaust system component for purifying harmful substances contained in the exhaust gas through oxidation and reduction by being mounted in an exhaust manifold and which detects the surface temperature of the exhaust system component in a non-contact method in order to provide the information for a control unit; and the control unit which estimates the temperature of the exhaust gas from the surface temperature of the exhaust system component provided from the non-contact sensor.
