Ethereal 3. 5. Displacement intake valve timing control cylinder group 1 what is the fault

First, the ignition timing does not have a great impact on the car, 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, the time when the spark jumps out of the spark plug is the so-called ignition timing. It is generally expressed in terms of the angle of how many crankshaft turns before the piston goes to the top dead center, such as 10° before the top dead center, rather than in time.

2. Ignition timing adjustment.

1. Adjust the gap between the power-off contacts of the distributor.

The size of the contact gap not only affects the strength of the spark, but also affects the opening and closing of the contact. If the contact gap is adjusted after adjusting the ignition timing, even if it is a small change. It will destroy the ignition time that has been adjusted, so the contact gap must be adjusted before the ignition timing adjustment, and the gap must be adjusted to 0

35～0.40 mm range.

2. Find out the position of the top dead center of the compression stroke of the first cylinder, and loosen the spark plug of the first cylinder.

Slowly shake the crankshaft, when you hear a deflating sound, it means that the first cylinder is compressing the stroke. Open the sight hole cover on the flywheel housing and slowly shake the crankshaft so that the timing mark is aligned.

3. If there is an octane number selector, it should be adjusted in"0"on the scale position.

4. Determine the position where the contact of the cut-off is just opened.

Unscrew the fixing screws of the distributor housing, and turn the shell along the direction of rotation of the distributor shaft first, so that the two contacts are in a closed position. Then turn on the ignition switch and turn the shell of the distributor in the opposite direction of rotation of the distributor shaft while facing the high-voltage wire of the ignition coil against the tie iron (about 2 3 mm) until a spark is found. Finally, tighten the set screws of the distributor housing.

5. Connect the high-voltage line according to the ignition order

Replace the fire divider, insert the first cylinder high-voltage wire into the plug-in hole where the distributor cover and the conductive piece of the distributor head are aligned, and plug in the high-voltage wire of each cylinder in the order of clockwise direction.

6. Start the inspection:

Start the engine to run to a normal temperature, accelerate suddenly, and if the engine makes a short and slight knocking sound and disappears immediately, the ignition time is appropriate. If there is no knocking 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. If the detonation sound is severe, that is, the ignition time is early, the distributor shell should be turned in the opposite direction of the above until it is suitable.

Hello, clean the variable timing solenoid valve. It is possible that the solenoid valve is stuck.

Summary. If there is this failure, it means that there is a problem with the control of your intake valve, this is not your timing is wrong, but your variable timing system has a problem, generally speaking, you can check whether there is a problem with the solenoid valve, you can replace a solenoid valve first, if there is no effect after replacing the solenoid valve, you should consider replacing your variable timing wheel, this is mainly because the variable timing wheel can not act before this failure will occur.

The Ethereal P0011 intake valve timing control B1 is because the timing is wrong.

If there is this failure, it means that there is a problem with the control of your intake valve, this is not your timing is wrong, but your variable timing system has a problem, generally speaking, you can check whether there is a problem with the solenoid valve, you can replace a solenoid valve first, if there is no effect after replacing the solenoid valve, you should consider replacing your variable timing wheel, this is mainly because the variable timing wheel can not act before this failure will occur.

Is it a VVT solenoid valve?

Yes, replace this vvt solenoid valve first, if the solenoid valve is okay, you should consider replacing the timing wheel inside.

Report this failure, the power goes up, and it rings.

If this fault occurs, it will definitely lead to a lack of power in the vehicle.

1. Open the cover (the engine oil injection port cover is rotated counterclockwise and pulled out), remove the engine protective cover (there are 3 triangular fixed points, and it is slightly laborious to disassemble and assemble), and twist the oil cover clockwise to prevent dust from entering the tank.

2. Check the intake and exhaust solenoid valves.

3. Remove the solenoid valve buckle and set aside.

Hold the small card with a functional tool, and take out the buckle from the left shake part.

The intake valve buckle is facing outwards and is unloaded. The exhaust is facing inward, which is a little troublesome.

4. Unscrew the screw of the solenoid valve with a special sleeve, pull out the old valve, and remove the buckle (the card connecting the wire) connected to the solenoid valve with a tool. Always be careful when removing the old valve and do not allow dirt to fall into the valve hole. Carefully wipe off dirt such as dust and oil from the surrounding area.

The specific operation steps of Nissan Teana engine timing are as follows:

1. The intake camshaft of the Dongfeng Nissan Teana engine.

The mark is aligned with the black mark of the chain.

2. Align the exhaust camshaft mark of Dongfeng Nissan Teana engine with another black Xianheling chain mark.

3. Rotate the Dongfeng Nissan Teana crankshaft.

of timing gears.

4. Let the timing mark point of the crankshaft of the Dongfeng Nissan Teana engine be aligned with the yellow brother chain mark.

5. In this way, the timing operation of the Dongfeng Nissan Nessan Teana engine is completed.

Summary. Kiss <>

Expansion: Exhaust valves are used in independent heating systems, central heating systems, heating pots, air conditioners, floor heating and solar heating system pipe exhaust. When there is a gas overflow in the system, the gas will climb up along the pipeline, and finally gather at the highest point of the system, and the exhaust valve is generally installed at the highest point of the system, when the gas enters the valve cavity of the exhaust valve and gathers in the upper part of the exhaust valve, with the increase of gas in the valve, the pressure rises.

You are very happy to answer your <>

Nissan Teana P0014 Exhaust Valve Timing Control Cylinder Group 1: Camshaft Position-Timing Caused by Excessive Advance. If the camshaft is mechanically stuck in front or the actuator valve is stuck in the open position, the timing system is premature.

The inspection team asked me to check whether the engine was not working properly due to lack of oil.

Kiss,**Received. The timing control of the exhaust valve is faulty.

There was a bit of sludge in the engine before, and it was all cleaned.

Kiss,**Received. The timing control of the intake valve in the exhaust valve is faulty.

Kiss, there is too much sludge inside the engine, it is best not to clean it. Use the cleaning agent to pour the engine cleaner into the fuel tank. After 5 to 10 minutes of idling, Chang Shixiao drains the old engine oil with cleaning agent into the engine empty, which is more resistant to changing the oil filter and adding new oil.

Cleaned with cleaning oil.

Thank you. Kiss, clean with cleaning oil, okay.

Dear, glad to answer for you. What does the first stroke of the fault code of the P0345 cylinder group 2 refer to Answer: Dear, the first stroke of the fault code of the P0345 cylinder group 2 refers to the first stroke caused by the speed sensor, and the fault phenomenon is no ignition, no fuel injection, and more directly, the ignition cannot be started.

If this kind of failure still occurs after replacing the sensor, it seems that the timing problem was not paid attention to during the assembly process after overhauling the engine, and it is recommended to re-align and install it to ensure that the timing is correct. Also, after replacing the sensor, be sure to clear the fault**.

There should be a problem with the variable air intake system.

Solution: 1. It is recommended to change the engine oil to give it a try, because after the oil becomes dirty, the cam rotation is not flexible or unpunctual.

2. Look at the timing mark of the engine.

3. Whether the connecting wire of the camshaft position sensor is loose. It is recommended to go to the 4S store to use, decode, coder, and check the data stream.

If it is all right, it is recommended to replace the ECU.

The cavity in which the piston is placed on the cylinder block of an internal combustion engine. It is the track of piston movement, in which the gas burns and expands, and through the cylinder wall, it can also dissipate a part of the explosive waste heat transmitted by the gas, so that the engine can maintain the normal operating temperature. The types of cylinders are integral and single-cast.

The single-cast type is divided into two types: dry type and wet type.

When the cylinder and the cylinder block are cast into a whole, it is called an integral cylinder; When the cylinder and cylinder block are cast separately, the single-cast cylinder barrel is called a cylinder liner. The cylinder liner is in direct contact with the cooling water and is called the wet cylinder liner; Those that do not come into direct contact with the cooling water are called dry cylinder liners. In order to maintain the tightness of the contact between the cylinder and the piston and reduce the friction loss of the piston in the movement, the inner wall of the cylinder should have high machining accuracy and precise shape and size.

It should be that there is a problem with the 3-cylinder variable air intake system on the side of the water tank, focusing on checking the solenoid valve [car problem, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello! It is recommended to refer to the following manual, which has detailed instructions.
