What is the control of the idle speed of the antelope car? Thank you

Antelope's engine, the earliest is also imported parts assembled in the Jiangling factory, model JL474Q1, in fact, it should be called Suzuki G13B, is a front-wheel drive gearbox for cars, when the Antelope was installed, the basic type of Antelope was sold, luxurious, the Antelope machine at that time was absolutely first-class, there was no such noise as the Antelope now, there was no idle jitter, fuel consumption was lower, and the quality and durability were better. Later, Suzuki and Chang'an discord, their own in Chang'an Suzuki company to build an engine production line, the production of the current antelope and swift engine, after the localization rate increased, the quality went downhill, but compared to the Jiangling plant, the small Japan control is much stricter, the EFI system still uses Japan DENSO, the swift is like the Chang'an Star to remove the distributor and replace it with a double ignition coil, the model is JL474Q5, which is the little Japan used to fool consumers, in fact, the engine of the antelope and the cylinder block of the Chang'an Star, The cylinder head and other structures are the same, single overhead camshaft (SOHC) 16 valves, it is belt driven, but it can not be universal, the displacement is also different Antelope 1301, Changan 1310, due to the difference in the design of the intake system, the power torque is different, the Antelope is slightly higher at 63kw, 110Nm, Changan 60kw, 100Nm, the actual use of power is still enough, the speed is pulled up after the stamina is very strong, the idle condition is relatively, there are obvious noises of "click", The shaking of the Antelope steering wheel is more serious (the Swift is said to not shake after improvement), the noise control is better than the Antelope Chang'an, the high-speed 130 or more two machines have the low-frequency jitter and noise of "Huohuo", the small problems are much less than Chang'an, and the overhaul mileage is also much better than the Antelope, but the 500,000 kilometers of the Antelope taxis boasted on the Internet are not overhauled, which are all early imported carburetor 472 engines, Suzuki G10 series, not the current Antelope Swift engine, and the current machine will reach 500,000 kilometers? Four words:

It's even harder, or four other words: Arabian Nights!

The idle speed of the car is controlled by the idle valve, the car with the carburetor can adjust the idle speed by the adjustment screw on the carburetor, and the EFI car can only adjust the idle speed of the car by adjusting the air intake.

What is the control of the idle speed of the antelope car? Thank you Idle 650 700 750 There is not much difference, Shenyang is ethanol fuel, it may be to catch up with the fuel impurities when refueling caused by the combustion of bad with jitter, so to speak, according to the traditional experience, will tell you to add a few good fuel will be good. In fact, it is not, because once the fuel contains impurities and colloidal moisture exceeds the standard, it is useless for you to use any fuel, because the fuel itself does not have the ability to clean these substances, so you need to use a detergent to clean these substances that affect the combustion of the oil circuit.

So how do gas stations try to avoid these impurities, moisture, etc.? It is the regular cleaning of gas stations, and gas stations also need to clean underground oil tanks, not to mention private car owners. Now it's clear.

I have also encountered the same problem, why the new car is so shaking, the problem is here, including the old car like most of the continuous slight shaking is caused by this reason, of course, the old car also has carbon deposition factors, because long-term combustion is not good, a large amount of carbon precipitation affects the combustion more intensely, and the old car is weak and shaky. My experience is that according to the size of the fuel tank, use one to three Siyoupu additives to add to the fuel tank, and this problem will be solved after 1 to 3 tanks of oil after normal driving, saving trouble, effort and money. You can learn from this real experience.

The cause of high idle speed of a car is the situation caused by excessive carbon deposits in the engine of the car.

The solution is: go to the 4S shop or repair shop of the car in time to clean up the carbon deposition of the car engine in time to solve the problem of high idle speed of the car, if it has not been solved, it is recommended to overhaul the car engine.

Generally speaking, the common causes of high idle speed of the automobile engine are: throttle stagnation and poor closing; Failure of the idle control valve; Faulty water temperature sensor; The air intake system is leaking, and the air conditioning switch and power steering pressure switch are faulty. Carbon deposits that cause the idle control valve to act, the hairpin or the throttle valve to close inadequately will prevent the ECU from making accurate idle adjustments to the engine.

First clean the intake system, once again dismantle the throttle, check whether the idle motor is broken, and later found that there is no problem with the idle motor, in fact, for the antelope this broken car, after the generator heats up, the idle motor, the oxygen sensor, it doesn't matter if it works or not... The idle motor only controls the idle speed of a cold car, and the adjustment effect of the oxygen sensor is not very large.

The negative pole is removed from the battery.

Tear it down and see the structure inside.

Since I don't know how to wash it, I spray it casually with carburetor cleaner first...

Take apart the motor and take a look... There are two small Phillips screws, just unscrew them.

<> is like this, the egr waste valve is actually a small motor.

This is the bearing of the rotor...

Next, my brother suddenly found that there are two screws on the base of the EGR valve, 13mm. Find a wrench to take it apart and take a look...

It's taken down.,Wow.,That's a lot of carbon deposits.。。。

<>10.Damn.,The hole above is actually blocked.。。

11.If you look at it from the inside, there is a thin tube in the blocked tube, so it is easy to get blocked...

12.Piercing it with a needle and awl, you have to use a lot of strength, and it takes a lot of effort. . .

13.Next, the exhaust gas pipe of the EGR was dismantled, the metal pipe was also covered, and the insulation layer was wrapped. 、。I don't know why、。。 Two screws, 17mm...

14.Yes, the pipe was removed, and there was carbon deposits in the pipe. Install it back after cleaning.。。

15.Install the reset. EGR valve base. It's best to apply some sealant...

<>16.Install the egr valve and install the plug. In fact, the abandoned ** system is of little significance to antelopes, especially the old antelopes.

17.Next, the pump pressure relief valve is connected to the intake manifold. I found that it was not blocked...

18.This is the angle grinder I just bought online, 70 oceans, ready for sheet metal painting, last time I bought an air pump and spray gun, 300 oceans...

19.Go ahead and remove the throttle body... The two tubes in the picture below are still not hot, I guess it has a lot to do with the cylinder gasket.

20.Idle air valve,Remove it again and observe,See if there was a problem with the installation last time.。。

<> to be continued.

Common causes and solutions for antelope car idling instability:

1.The engine has a lot of carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposition after the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more the presence of carbon deposits will affect the cold start.

Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug tripping condition is not good, which will also lead to this kind of failure.

Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad and spark plug, etc., and still found that the body shakes when idling, it is recommended that you go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is not good, the body shake will be triggered.

Solution: Check the oil pressure and replace the parts if necessary.

4. Aging of engine parts.

Car jitter is also related to the aging of the engine feet (also known as claw pads). The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

Workaround: Replace the parts.

Check it, first, to see if it is not high, if it is, then adjust the bottom point; The second one is likely to be that the throttle is dirty and needs to be cleaned.

Go check it out:

See if it's high, and if so, adjust the bottom point.

This is most likely because the throttle is dirty and needs to be cleaned.

Only when the air conditioner is turned on will it idle unsteadily, there are the following reasons:

1.The engine control logic is faulty and cannot receive the signal that the air conditioner is on. When it is not possible to determine whether the air conditioning is turned on or not, the engine control unit (ECU) mistakenly thinks it is a short-term high load in an attempt to increase the rpm to counteract the drag at idle.

When the engine speed drops, it cannot bear the load of the air conditioning compressor and increases the speed again. Back and forth, it behaves as unstable idling.

2.The air conditioner control circuit is faulty and cannot send the air conditioner on signal. In the same way as the first one, because it is impossible to determine the state of the air conditioner on, the ECU will continuously adjust the idle speed, which will behave as an unstable idle speed.

3.The air conditioner circuit is faulty, causing the air conditioner to work intermittently. When the air conditioner is not working, the air conditioner compressor belt is idling and no-load state, so it will not affect the engine load.

The continuous intermittent operation of the air conditioning compressor causes the engine to continuously adjust the idle speed, which is manifested as unstable idling.

Under normal circumstances, almost all vehicles will have an increase in idle speed when the air conditioner is turned on, and it is normal to increase by 100 to 150rpm.

When the air conditioner is turned on, the air conditioner compressor is driven by the air conditioner compressor belt, and the belt drive force comes from the engine. Therefore, in order to ensure that the idle speed will not be stalled due to additional engine load in the idle state, the idle speed of the vehicle with EFI control and belt drive air conditioning compressor will increase.

EFI engines all have an engine control unit that controls and adjusts the appropriate idle speed to keep the engine running in a low-power state and not being extinguished.
