COMMON-RAIL is a common rail diesel power system. (A diesel engine supply system in which a high-pressure pump delivers fuel to a common battery – rail, and fuel is supplied to the engine cylinders using electronically controlled nozzles. The system operates at high pressures, more than 100 MPa, and provides better performance, fuel economy and lower noise of diesel operation).

CTPS – contact tire pressure sensor. (A sensor installed in the pneumatic tire, the signal from which is used to inform the driver about the pressure in each specific tire of the car).

CVT (Continuously Variable Transmission) – – continuously variable transmission with variator.

DCG (Direct Shift Gearbox) – direct shift gearbox (Automatic transmission with parallel driven shafts, in which gear shifting occurs without breaking the power. Developed by Audi and used in series on the company’s cars)

DOHC (Double Overhead Camshaft) – Timing with two shafts in the cylinder head. (The drive of such gas distribution mechanisms is carried out from the crankshaft of the engine using a chain or belt drive).

It provides the most optimal braking force on the axles, changing it depending on specific road conditions (speed, nature of the coating, vehicle loading, etc.). Mainly to prevent rear axle wheels from locking. The effect is especially noticeable on cars with rear-wheel drive. The main purpose of this unit is the distribution of braking forces at the time of the start of braking of the car, when, according to the laws of physics, under the action of inertia forces, a partial redistribution of the load occurs between the wheels of the front and rear axles.

Electronics compares loading parameters, vehicle speeds and evaluates the condition of the roadway. When driving on good tracks, the EDC “orders” the shock absorbers to become softer, and when cornering at high speed and driving undulating sections, it adds rigidity and provides maximum traction.

Power Steering (power steering) – A system consisting of a pump and hoses to facilitate steering. Power steering especially helps when turning wheels on a stationary vehicle and with low-profile rubber, because in this case “the contact patch of rubber with the road is maximum, and there is no rolling. Of the power steering disadvantages, it can be noted that when the steering wheel is turned quickly, the pump may not have time to pump fluid and overheating, which will lead to resistance in rotation.Fortunately, this is unlikely on modern cars.

The EUR (electric power steering) is the same as the power steering, but instead of a pump that pumps liquid, the role of an assistant is performed by an electric motor. In case of overheating, the EUR will turn off for 3-4 seconds, then turn on again.
