The clutch slips until the input and output RPMs are matched. This happens relatively quickly typically (0.2 - 2 sec). When the current is removed from the clutch, the armature is free to turn with the shaft. Springs hold the friction disks away from each other, so there is no contact when the clutch is not engaged, creating a minimal amount of ...
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
July 2018) (Learn how and when to remove this message) An idle air control actuator or idle air control valve ( IAC actuator / valve ) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed ( RPM ). [ 1 ]
Based upon the size of the clutch or brake, the speed and the inertia, wear rates will differ. For example, a machine that was running at 500 rpm with a clutch and is now sped up to 1000 rpm would have its wear rate significantly increased because the amount of energy required to start the same amount of inertia is a lot higher at the higher speed.
Historically, a dual-clutch transmission shifts faster than a standard hydraulic automatic transmission with a torque converter or a single-clutch automated manual transmission. This is possible because the DCT can pre-select the next gear and transfer torque from one clutch to the next clutch with the pre-selected next gear, thus reducing ...

In such an air conditioning system, the accumulator also prevents the liquid refrigerant from reaching the compressor during low cooling demand periods. The air, often after being filtered by a cabin air filter , is blown by an adjustable speed electric powered centrifugal fan across the evaporator, causing the liquid part of the cold ...
Cars with manual gearshift use a clutch. Clutches are controlled from pedal by bowden cable or hydraulic systems, some use the fluid in common with the brake system. As a dead end of the hydraulic system, the slave cylinder is equipped with a bleed screw.
