To start an internal combustion enginean enriched combustible mixture is required. In order to prepare it in the power system, a starter is provided. In the classical version, this role is played by the air damper. To start the engine, the throttle remains slightly ajar, and the air damper is closed. Now, when the crankshaft is cranked when starting the engine, a vacuum is created inside the carburetor, which facilitates the flow of fuel from the nozzles in the main dosing system of the idling system. Equipping the air damper with valves with springs leads to an automatic air supply when the engine starts.
As the engine warms up and startsto work stably, the flap is opened. In the future, with all modes of engine operation, the air damper is completely left open. To control the air damper, a hand grip is used, which is located in the cockpit.
The throttle is controlled in two ways. Or by grip during warming up the engine, fix the desired frequency of rotation of the shaft, or a foot pedal, returned by the spring to the starting position.
Progress does not stand still, and modern cars with incredible speed are equipped with the latest technological "gadgets", they embody and original technical solutions.
The throttle was also not left outin this plan. Electronics was replaced by mechanical traction and cables. The electronic throttle drive not only "cultivated" the engine compartment of the car, relieving the excess of mechanical components, but also introduced additional comfort and convenience into the vehicle's control. The fact is that, having got rid of mechanical control, the new system allows you to control the operation of the throttle not only to a person, but also to electronics, which is much more efficient in coping with this task.
Having thoroughly studied the structure of his car,You can actively fight the emergence of many different problems in his work. For example, a rather irritating effect is the vibration of the engine in idle. Among the reasons that cause it, there may be low-quality gasoline, poor technical condition of supports, and candles that have served their time. One of the reasons for the vibration may be a throttle valve block, or its failure, or contamination with crankcase gases.
The throttle plate plays an important role instable operation of the motor, and its operating state is influenced by many factors. A worn engine can itself throttle the idling channels with oil and soot along the ventilation of crankcase gases. A clogged air filter can also cause scaling.
Malfunctions mass, but "treatment" of them occurs on the same algorithm.
First we check and replaceair filters, candles, high-voltage wires. Then we clean the idle channels with a carburettor cleaner. We regulate the idle speed with an electronic regulator, as well as a bimetallic plate.
Flushing the throttle valve often givesfantastic results. The engine, which is poorly wound up and did not produce the required power, acquires a new force, it works smoothly and starts, which is called a half-turn. This procedure does not require special skills, it can master any driver, who knows a screwdriver and another tool. To the aid will come the means of modern autochemistry, as well as a manual for the operation and repair of your car.
Also it is necessary to take care of high-quality fueland oils, it is necessary to monitor the performance of other consumables. Often, regular maintenance of the car is much cheaper than the subsequent repair.
