After the Roewe 350 replaces the timing chain the timing is good with a special tool , the idle spe

How to solve this problem, I have encountered this problem now, and I can't go up 2,000 revolutions no matter how much I step on it.

I advise you to repair the 4S shop and make it difficult to do it yourself.

The specific operation steps of the timing chain system calibration of the Roewe 350S are as follows:

1. The timing point of the crankshaft corresponds to the special marking point of the chain.

2. The intake camshaft corresponds to a special marking point.

3. The exhaust camshaft has special marking points.

4. The two marking points of the intake balance shaft correspond to the special marking points.

5. The two marking points of the exhaust balance shaft correspond to the special marking points.

Rotate the flywheel to the flywheel pin hole and align with the body pin hole, insert the body timing pin hole and the flywheel pin hole with the flywheel locking special tool, lock the flywheel, lock the camshaft phase with the camshaft locking special tool, check whether the parts are damaged, oil, rust before assembly, if damaged, shall not be used, if there is oil stain, it must be wiped clean, the chain guide rail is put into the upper end of the right side of the guide rail compartment, respectively, the pivot pin is tightened for the last time, and the tightening torque is 22-28nm.

The ignition is not right to the car has a great impact, the combustion of gasoline in the engine must be ignited by the spark plug jumping out of the spark, to make the engine start smoothly, and burn well, the spark of the spark plug must be strong enough, but more importantly, the time when the spark jumps out must be appropriate and correct, too early and too late will affect the horsepower of the engine.

If there is no detonation sound, that is, the ignition time is late, the fixing screw of the distributor shell should be loosened, and the distributor shell should be rotated a little in the opposite direction of the distributor shaft rotation, if the detonation sound is serious, that is, the ignition time is early, the distributor shell should be rotated in the opposite direction until it is suitable.

The reason for the Roewe 350 timing chain jumping gear is that the chain is installed incorrectly and needs to be re-corrected.

Hello, I am glad to serve you and give you the following answers: the reasons for the problem: 1. The tension of the timing chain is not suitable, which increases the fuel pressure of the engine and increases the fuel consumption; 2. The wear of the timing chain is serious, and the fuel pressure of the engine increases and the fuel consumption increases.

Solution: 1. Check the tension of the timing chain, if it is not suitable, you need to adjust the tension of the chain; 2. Check the degree of wear of the timing chain, if the wear is serious, you need to replace the new timing chain. Steps:

1. Check the tension of the timing chain: first, keep the engine coolant temperature within 80 degrees, and then open the engine compartment cover to check the tension of the timing chain. 2. Check the wear degree of the timing chain: open the engine compartment cover to check the wear of the timing chain, if the wear is serious, you need to replace the new timing chain.

Knowledge of early jujube shed: The timing chain can ensure the timing operation of the engine and reduce fuel consumption. The tension of the timing chain must be adjusted according to the specified tension to ensure the timing of the engine.

The degree of wear and tear of the timing chain also needs to be checked regularly, and once the wear is found to be severe, it needs to be replaced with a new timing chain.

Summary. Hello dear, according to the relevant regulations of the manufacturer, the timing chain of Roewe 350 is maintenance-free for life. First, this depends on the degree of maintenance and care related to the vehicle, if it is usually maintained and maintained on time, this is related.

The timing chain does not need to be replaced. Second, if the vehicle has had oil loss or high temperature before, it is easy to lead to the elongation of the timing chain, then this normal specific depends on the number of kilometers traveled by the vehicle, generally after 150,000 kilometers. Third, the relative cost of replacing the timing chain is relatively high, which is generally about 1500 to 2,000.

Charges vary by region**. Hello, I wish you a happy family, if necessary, you can continue to consult, I will always wait for you to reply Kiss

There is no loss of engine oil, high temperature, and I need to change it after driving 130,000 kilometers at present.

Speak. Hello friends, there has been no oil loss, there is no high temperature, then this does not need to be replaced.

Pacific Automobile Network] 150,000 kilometers to replace on the line, the service life of the timing chain has a lot to do with the oil used in the usual maintenance of the car. The main function of the engine timing belt is to drive the valve mechanism of the engine, so that the engine intake and exhaust valves can be opened or closed at the appropriate time, so as to ensure that the engine cylinder can be suction and exhaust normally.

How many kilometers does the Roewe 350 timing chain change? The Roewe 350 timing chain is recommended to be changed once every 150,000 kilometers. The main function of the engine timing belt is to drive the valve mechanism of the engine, so that the engine intake and exhaust valves can be opened or closed at the appropriate time, so as to ensure that the engine cylinder can be inhaled and exhausted normally.

Here are the steps to replace the timing chain:

1. Disassemble the valve chamber cover, disassemble the crankshaft pulley, and remove the chain shell when the finger is arguing; Rotate the crankshaft, turn the crankshaft to the top dead center of a cylinder, screw the crankshaft fixing screw, and fix the crankshaft;

2. Rotate the intake and exhaust camshaft, there is a groove at the rear end of the camshaft, align the grooves of the two camshafts in a balanced manner, and snap the special tool into it;

3. Remove the old chain and replace it with a new one. The crankshaft belt bumper wheel is without a slide key, and when installed, there is a round hole on the top of the pulley, which is aligned in the groove above the chain shell;

4. The crankshaft position sensor can be adjusted, and the gap should be adjusted in place during installation, otherwise the fault code will be reported; Both the crankshaft sprocket and the pulley rotate freely.

Not a major overhaul

Generally, the life of the belt tensioner is 2 times that of the belt. That is, if the belt life is 60,000 kilometers, then the tensioner life is 120,000 kilometers. If it is a chain tensioner, its life is equivalent to the chain, and now many cars are maintenance-free, that is, they do not need to be replaced for life.

The main significance of the timing chain is to simply say that the power from the crankshaft is transmitted to drive the valve mechanism of the automobile engine to ensure that the cylinder piston of the automobile engine can normally complete the four strokes of suction, combustion, work and exhaust to ensure the normal operation of the automobile engine. Generally, timing chains are used normally at 150,000 kilometers, and most of them are inspected after the car has been driven for 200,000 kilometers. If the car is overloaded and high-speed for a long time, it must be considered for 5 years or 75,000 kilometers must be inspected, and if the wear is serious or there is other damage, it must be replaced in time.

In general, the reliability of the timing chain is very high, and it still depends on the driving environment and other external aspects of the key due to slippery grinding. According to the use conditions and environment, the inspection is carried out on time, and the burial is replaced if necessary. With the continuous development of automotive technological innovation capabilities over time, the timing belt of some automobile engines has been replaced by automobile engine chains, which are reliable, durable and space-saving compared with traditional belt drives.
