Switch the throttle control unit reports on the status of the throttle at idle. The control unit opens or closes the throttle through the servomotor and thus maintains a stable idle speed. Coolant temperature sensor and the temperature of the air entering the engine by changing its resistance when the temperature reported by the engine control unit corresponding to the temperature. Fuel vapor recovery system consists of an activated carbon filter and the solenoid valve. Activated carbon filter prevents fumes penetrating fuel from the fuel tank into the atmosphere and evaporating the fuel is accumulated in the activated carbon. When the engine fuel vapors under the control of the solenoid valve again fed into the engine for afterburning. The oxygen sensor It measures the oxygen content in the exhaust stream. The control unit in its signal supports the content of harmful emissions in the exhaust gases at the lowest level. On vehicles with the catalyst composition of the exhaust gas is maintained at a level that ensures the best possible post-combustion in the catalyst. Knock sensor serves to detect the onset of knock in the engine cylinders and based on this information, the engine control unit reduces the ignition timing. If there are faults ignition control unit shuts off the fuel to the corresponding cylinder. The engine 1,8-I ADR, V6 engine
In these engines, the air supply system is applied to the motor of variable length, which, depending on operating conditions of the engine changes the length of the path of air entering the cylinders. For this purpose, butterfly valve, actuated pneumatically. At low engine speeds the air flows along a longer path and by using resonance, is a more complete filling of the engine, thereby increasing torque. The V6 engine
In these engines, depending on the engine speed occurs dovorachivanie distributor tion camshaft operating intake valves, resulting in altered valve timing. Set the optimum valve timing for the respective engine speed increases engine power at all engine speeds.
