A variable intake system includes a pair of surge tanks connected in a communicating manner to a main intake pipe through a low speed communication pipe and a high speed communication pipe, a middle speed communication pipe for connecting the pair of surge tanks, and a noise reducing member integrally provided at the middle speed communication pipe to reduce noise.

Variable intake system

An idle throttle valve control method of a diesel vehicle, may include a first step of determining whether an idle entry condition of the vehicle may be satisfied, a second step of controlling a throttle valve based on an air amount map and controlling an exhaust gas recirculation (EGR) valve based on an EGR map, when the first step may be satisfied, a third step of determining whether an idle release condition may be satisfied during the second step, and a fourth step of determining whether an EGR return condition may be satisfied, when the idle release condition may be satisfied in the third step.

Control method of diesel vehicle

An apparatus for reducing transmission shock of an automatic transmission may include a piston operated by a control pressure, a clutch performing a clutching operation by an operation of the piston, and a cushion spring arranged between the piston and the clutch which varies by stages in stiffness of the spring with an operating position of the piston. The cushion spring may be formed with one or more sets of a plurality of curved-surface springs bent in an operating direction of the clutch and connected with each other, each set of the plurality of curved-surface springs having a different bending height.

Apparatus for reducing transmission shock in automatic transmission

A method of controlling a transmission of a vehicle may include generating a first synchronization force between a shift gear of a target gear and an output shaft to shift gears from a current gear to a lower gear set as the target gear in response to deceleration of the vehicle, so as to form a first synchronization, removing the first synchronization force between the shift gear and the output shaft after the generating of the first synchronization force, and generating a second synchronization force between the shift gear of the target gear and the output shaft after the removing of the first synchronization force, so as to form a second synchronization.

Method of controlling transmission of vehicle

A method of controlling a transmission of a vehicle may include beginning synchronization between a speed shift gear of a target gear and an output shaft to shift gears from a current gear to a lower gear set as the target gear in response to deceleration of the vehicle, after the synchronization between the output shaft and an input shaft by the speed shift gear of the target gear has been completed, maintaining the synchronized state therebetween for a predetermined time period, and completing engagement with the target gear to complete the shifting of the gears after the maintaining of the synchronized state.
