The electronic MRT system is installed on cars with engines having two camshafts, and controls the traction force with a pound of drive wheels, thereby preventing wheel slip, regardless of the condition of the road or tires. This is especially important when driving on slippery roads.
The RTU system is controlled by an electronic control unit, which receives information from the anti-lock braking system electronic control units (ABS) and Motronic (engine). Four wheel-mounted ABS sensors (chapter 9), constantly monitor the traction force of the front wheels by comparing their speeds of rotation with the speeds of the rear wheels. The corresponding signal is sent to the RTU electronic control unit, which actuates the auxiliary throttle, which reduces the speed (and torque) engine to the optimum level.
The RTU system throttle is installed in a housing located between the main throttle housing and the intake manifold. The throttle valve is actuated by the control motor through the connecting rod. A potentiometer is located in the control motor, which supplies information to the RTU control unit about the position of the throttle valve.
If desired, this system can be turned off with a button on the center console. This may be justified in some cases, such as when driving in deep snow or soft ground (sand).
