Abstract: A vehicle remote diagnosis service system includes a remote diagnosis server that transmits a first collection rule to at least one vehicle; and the vehicle that transmits an identification number and a failure detection signal collected according to the first collection rule to the remote diagnosis server when a failure corresponding to the first collection rule has occurred, and transmits information collected according to a second collection rule to the remote diagnosis server when the second collection rule is received from the remote diagnosis server.

Abstract: A self-diagnosis method for an ignition coil includes receiving and confirming a current flag (C/F) signal through monitoring of primary current of an ignition coil; monitoring secondary current of the ignition coil upon receiving the C/F signal and confirming whether a fault flag (F/F) signal for determining whether misfire of the ignition coil occurs is input; and determining whether an abnormal signal of the ignition coil is generated based on the result of confirming the C/F signal and the F/F signal respectively.

Abstract: A method for releasing a catching of a locking pin may include a control application step of releasing the locking pin from a locking pin hole by an electronic control unit (ECU) so that a catching phenomenon of the locking pin due to friction force into a rotation direction of a cam is prevented, and a cam shaking prevention control logic alternately performing, by the ECU, a holding control stopping a rotation of the cam and a rotation control of the cam into a target direction so that it is prevented that the cam is rotated in a direction which is opposite to a rotation target direction of the cam when the releasing of the locking pin is completed.

Abstract: An apparatus for supporting a waste gate module includes a support bracket connecting the waste gate module and a turbocharger housing, and a coupling protrusion formed on a face of the support bracket and that faces the waste gate module, where the coupling protrusion has an end coupled to the waste gate module.

Abstract: A method for controlling an exhaust gas recirculation (EGR) system includes a first step of determining whether the EGR system is in an operation section under an ignition-on state, a second step of calculating a catalyst deterioration index with catalyst deterioration-diagnosing logic in a section that is determined to be the operation section of the EGR system, and for sensing an occurrence of a misfire in an engine with misfire-sensing logic, a third step of deciding whether the catalyst deterioration index is abnormal on a basis of a first predetermined value and whether a frequency of the misfire is abnormal on basis of a preset value for a reference duration, and a fourth step of controlling an opening amount of an EGR valve based on the decision of the abnormality of both the catalyst deterioration index and the misfire frequency.

Abstract: A method of controlling a CVVT includes: a very low temperature condition deciding step of deciding whether or not an engine is in a very low temperature condition state on the basis of information received from the engine at the time of starting up a vehicle in a controlling unit; an operation number confirming step of confirming the number of operations of the CVVT after starting up the vehicle when the engine is in the very low temperature condition state; and a very low temperature condition applying step of applying a very low temperature condition at the time of controlling the CVVT when the number of operations of the CVVT after starting up the vehicle is less than a predetermined number input to the controlling unit.

Abstract: A fuel cutoff system for a liquefied petroleum injection (LPI) vehicle includes a bombe that stores liquefied petroleum gas (LPG) fuel. At least one injector is connected to a fuel pump, which is disposed in the bombe, through a fuel supply line, and the at least one injector is provided in an engine to supply the LPG fuel fed through the fuel supply line to the engine. A fuel return line interconnects the engine and the bombe, separately from the fuel supply line, through which the LPG fuel returns to the bombe from the engine. At least one fuel cutoff valve is provided on the fuel supply line. The at least one fuel cutoff valve is electrically connected to an ignition key and activated by an ignition power supplied depending on whether the ignition key is in an On or Off position.

Abstract: The present invention includes a VCM apparatus, and method of use, to create tumble in an engine combustion chamber while suppressing costs of engine manufacture by appropriately diagnosing failure conditions such as a deformation of a flap and a damage of a link connecting the flap to a VCM actuator without the need for an additional sensor mounted near the flap.
