Contaminated throttle can cause malfunction of the engine, causing a significant drop in output and the deterioration of the vehicle acceleration dynamics.Over time, this element tends to become dirty, so to avoid similar problems with the car, you need to know how to properly clean the throttle.Today we look at how you can do it with your hands.
Why need this item?
For starters take a few words intended throttle and its role in the operation of the engine and the vehicle as a whole.The main function of this element is to feed air into the manifold.In operation, the valve is in its fully open position.After the air is mixed with fuel, formed by the fuel-air mixture.Then it enters the combustion chamber of the engine.Thus, the concentration and the proportion of air in the mixture directly affects the quality of the motor, as well as its power and traction characteristics.When the engine stops working, the valve closes and the air flow is stopped.But not always the valve closes when the motor is shut.This happens when the engine is running.All you need to do - just let the gas pedal.By the way, at the muffled engine when pressed on the accelerator, we also open the valve.It works silently, but if the pedal is abruptly released from under the hood, you will hear a click - it will be the sound of closing the throttle.A pedal binds to this element by means of mechanical drive.That's the way most of today's dampers.
What signs indicate a clogged valve?
Firstly, this may indicate a problem with frequent starting of the engine.Secondly, clogged valve sometimes provokes jerks while driving, especially at the start.Also noticeably worse operation of the engine at idle speed (revolutions begin willfully "float").And thirdly, it is a marked deterioration in the auto acceleration dynamics.
Nuances
However, to say that all of these signs indicate a problem it flaps impossible.There are numerous other factors.Therefore, you first need to check the condition of the spark, the fuel filter (which also has the ability to clog over time) and the throttle position sensor.If all these elements are in good condition, most likely, the shutter does require cleaning.
Why is this happening?
mixture of oil and air, as well as various microparticle dust of the road, passing through the air filter may gradually covers the surface of the parts and components of the engine compartment, thereby greatly suffer throttle.It happens rarely, but the item must be cleaned at least once a year.Otherwise, incorrect operation of the engine will be inevitable.
treatment options
Before tell you about all the stages of cleaning, we note that the throttle can be processed in any solvent, and both surface and fully.Among such means can distinguish gasoline, mineral spirit and WD 40. But compared with the specialized materials designed specifically for cleaning valves, they are less efficient and therefore suitable only for external processing.This is used only if the items are not much stubborn dust and dirt.In more advanced cases, it is best to use a thorough cleaning.It is the most effective and efficient.
How to clean the throttle yourself?Training tools
Before you begin this operation, you need to prepare the following tools and materials:
- Allen Key to 13.
- means for flushing the throttle (these are usually sold in auto stores), such as Abro.
- Set freezing and Phillips screwdrivers.
- pair of rubber medical gloves.They will protect your skin from possible dripping cleaner.For complete safety, of course, you can wear and goggles, but it is not necessary.
If you have just set, you can safely get to work.
Cleaning the throttle body assembly with his own hands?
First we need to find a place where the given item.A throttle valve is located before the inlet manifold.So, first remove the decorative plastic engine cover (if any design of your car).Next, unscrew the expansion tank cap.So we reduce the level of pressure in the cooling system of the car.After that, take out the air ventilation hose nozzle.The last item should be checked for signs of oil.If they are present there, then, in the throttle assembly packed thin channel ventilation.
Now, actually, about how to clean the throttle.Next, we take a Phillips screwdriver and weaken the two clamps.Then dismantle the pipe heating valve (can stifle automotive spark plugs).After taking out the hose of the fuel tank ventilation system (this one screwdriver unscrew the clamp).Now we have to remove the rope and two nuts throttle knot.
half the work we have already done, you can start most responsible step - cleaning the valve components from dirt and other deposits.To do this, take the purchased cleaner and washed out damper and all its channels.Pay attention and forced ventilation channel.It is this node is most coked (sometimes to clean it you want to apply a steel needle or a long needle).Throttle sensor also takes over the dust, so it can also remove and clean from deposits.
Then unscrew two bolts of fastening of a regulator of idling car.And then the IAC is removed outside.How to clean the throttle after that?Now, the channel should be rinsed in the housing unit.By the way, if the regulator has not changed idling more than 100 thousand kilometers, it is best to install in its place a new one.Also if necessary changing rod IAC (but only if it has a large backlash or charred to such an extent that it can not fully clear).Pay attention to routing of the throttle assembly.It is recommended for cleaning damper immediately replaced.Everything at this stage the question "how clean the throttle sensor and assembly of parts" can be considered closed.Then you need to collect all the parts in reverse order and check the result.As a result, the engine must get a "second wind."After cleaning the valve it will begin to work normally, without jerking and falling output.
Conclusion So, we figured out how to clean the throttle."Priora" (VAZ-2170) and many other cars are repaired by such principle.Therefore, these instructions can be used for absolutely any SUV or cars.As you can see yourself from dirt and dust, and can choke on their own.The main thing - to choose a really quality cleaner and do not forget about security measures when dealing with such means.
