Abstract: A method for controlling a variable swirl valve is provided to prevent the variable swirl valve from making contact with a stopper by limiting a minimum value and a maximum value of a duty for controlling the variable swirl valve. A controlling method for a variable swirl valve comprises the step of starting a variable swirl valve-protection mode, if a turn-on signal of an engine is detected(S103). A variable swirl valve-control duty is read(S104) and it is determined if the variable swirl valve-control duty is suitable for controlling an initial opening control state or an initial closing control state(S105,S110). If the variable swirl valve-control duty is suitable for the initial opening control state or the initial closing control state, it is determined if the variable swirl valve-control duty is continuously output(S106). If the variable swirl valve-control duty is continuously output, the variable swirl valve is controlled such that the variable swirl valve has an operation speed corresponding to a half of a normal operation speed of the variable swirl valve(S107). Then, it is determine if an opening control duty and a closing control duty are below a minimum limit and above a maximum limit(S108,S113), respectively. If the opening control duty is below the minimum limit, a lowest value of the opening control duty is limited. If the closing control duty is above the maximum limit, a highest value of the closing control duty is limited(S109,S114).

Abstract: PURPOSE: A method for controlling engine torque for a power take-off using CAN communication for an electronic-type diesel engine is provided to optimize the capability of a power take-off. CONSTITUTION: It is judged whether a clutch switch of a vehicle mounted with an electronic-type diesel engine is operating(110). If so, it is judged whether a power take-off switch is operating(120). If so, a lamp of a power take-off is lighted(130). A car speed is compared with a predetermined speed(140). If the car speed is lower than the predetermined speed, an RPM(Rotations Per Minute) of the engine of the vehicle is compared with a predetermined RPM(150). If the RPM of the engine is smaller than the predetermined RPM, a torque increase required by the power take-off is transmitted to an ECU(Electronic Control Unit) through CAN(Controller Area Network) communication(160). The ECU changes the torque increase into a fuel amount of the engine to increase a spray amount(170).

Abstract: PURPOSE: A noise reduction system of an EGR(Exhaust Gas Recirculation) valve is provided to reduce noise by removing the hysteresis of an EGR valve. CONSTITUTION: An intake manifold(20) is installed at one side of an engine. An EGR path(22) is formed separate from an exhaust path(21). An EGR valve(23) is driven by the pressure difference of the EGR path. A vibration modulator(25) modulates vibration pressure from a vacuum pump(24) and supplies the modulated vibration pressure. A hysteresis logic(26) suppresses frequent on/off motion of the EGR valve. The hysteresis logic determines an EGR uppermost limit value and an EGR lowest limit value depending on engine rpms.

Abstract: PURPOSE: A control system for preventing the rapid start of a vehicle and wrong operation of an accelerator controls fuel injection, engine rpm(revolutions per minute) and fuel injecting time when rapid start is occurred or an accelerator pedal is maintained to be pushed without being trod. CONSTITUTION: Rapid start preventing action is implemented if engine rpm signal, throttle position sensor signal and brake switch signal are all inputted in an engine control device. At least one of the signal is not inputted, the rapid start preventing action is released. Thus, fuel injection, engine rpm(revolutions per minute) and fuel injecting time are controlled, thereby preventing the rapid start of a vehicle and the wrong operation of an accelerator pedal.
