Is the Chery A5 engine 481F and 481H the same?

The A5 series uses the ACTECO series engine. There are three versions of 0, 8 and 6, which are similar, but the displacement is different. Although Chery claims to have many new engines with independent intellectual property rights, the actual application is the ACTECO engine. Almost. That's all I can think of.

There are currently two models of the Chery A5 series, one is A520, one is A516, both of which are standard models equipped with the ACTECO engine independently developed by Chery. The other is 0 liters and 6 liters, which is one of the engines with the highest technical level in China at present, which is comparable to imported engines.

The specific corresponding engine models are 6-liter Chery SQR481FD, 8-liter Chery SQR481FC and 0-liter Chery SQR484F.

The steps and methods of timing adjustment of Chery a5SQR481H engine are as follows. 1. Remove the engine belt, jam the tensioning wheel bolt with a wrench, and use force counterclockwise to remove the engine belt. Two. Remove the right suspension bracket of the engine, hoist the engine with a small crane, remove the right suspension bolt of the engine, and remove the right suspension bracket.

It is also easy to jump teeth when the engine load is heavy or the power is impacted, which may cause the top valve, thus damaging the engine. It is best to adjust the elasticity of the belt until it is 10mm loose and can be turned over 90 degrees.

Aim the arrow of the Chery A5481 engine balance shaft at the white link of the large chain. Aim the arrow of the Chery A5481 engine intake camshaft at the purple link of the chain. Aim the exhaust camshaft arrow on the right side of the Chery A5481 engine at the blue link.

sqr481f engine parameters

SQR481FD series independently developed 6L engine , the maximum power is 85kW/6150rpm, and the maximum torque is 147N·m/4300rpm. Such data should be said that the engine of the same level should be a moderate one.

Ruihu 3 is divided into three models in terms of displacement: the 6L displacement engine of the model SQR481F, the 8L displacement engine of the model SQR481FC, and the Mitsubishi 4G63 engine with a displacement of 0L. Through data comparison, the engine performance parameters of Ruihu 8L displacement exceed those of the 4G63 engine.

Due to the larger displacement, the maximum power of the 8-liter engine is 97kW and the maximum torque is 170Nm. The Chery SQR484F engine is matched with the 0-liter Chery A3 model.

Chery 481 engine idling shaking after replacing the timing belt

Many times the phenomenon of shaking when changing the timing belt at idle; if it is confirmed that it is caused by shaking after changing the belt, in the accessory type If the number is correct, it may be necessary to insist on whether the timing is right or not. The deviation will cause weak shaking. Please check again.

After replacing the timing belt, the idle jitter is correct. First, check whether the timing is correct. Improper assembly will lead to idle jitter. Secondly, checkWhether the ignition system is faulty or not, the poor operation of spark plugs, high-voltage wires and ignition coils will also lead to unstable idle speed.

Solution: It is recommended to clean the engine carbon frequently. Empty air filter: If it is not replaced in time, it will cause insufficient air intake and lower engine idle speed, resulting in engine shaking. Solution: Replace the empty air filter.

The engine has serious carbon accumulation. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

Specific reasons and solutions for unstable idling after the car starts: intake manifold leakage: when the air, gasoline vapor and combustion exhaust gas that should not enter the intake manifold, the mixture is too thick or too thin, resulting in unstable idling of the car. Solution: Check the manifold and replace it in time if there is air leakage.

Ruihu 481 engine 1.6 engine thermostor position

1. Chery thermosulator is located at the outlet pipe of the engine, that is, the water pipe on the water tank. Working principle of thermoster: The thermoster automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, changes the circulation range of the water, so as to adjust the heat dissipation capacity of the cooler and ensure that the engine works within the appropriate temperature range.

2. In the pipe between the sewer pipe and the engine interface, pull out the pipe to see the thermosulator. The delicate paraffin in the thermosulator is solid. The thermostrot valve closes the channel between the engine and the radiator under the action of the spring, and the coolant returns to the engine through the water pump for small circulation in the engine.

3. Generally speaking, the thermoster is installed at the water outlet of the upper part of the engine;The water temperature sensor is installed on the engine body behind the thermostat, that is, between the water pump and the thermostat. Sensors can be roughly divided into air intake system, oil supply system and ignition system according to their systems.

4. The thermoster is in the water pipe leading to the water tank on the cylinder head, and there is a small water pipe connected to the water pump next to the thermoster. There is a child's hand-sized cavity next to the valve cover, on the side of the belt, where it is connected to the water pipe of the water tank.

5. In the past, the installation position of the engine thermoster has been proved in practice that the installation of the thermostat at the outlet of the upper part of the engine will make the engine unstable during warm-up, and the fuel consumption will be high, which will make the engine performance worse and accelerate the wear of the engine.

6. The thermostat must maintain a good technical condition, otherwise it will seriously be affected by the engine.Normal operation, there is no thermosulator installed on the car water tank, which is installed in the water pipe leading to the water tank on the cylinder head. Next to the thermosulator, there is a small water pipe connected to the water pump, on the belt side next to the valve chamber cover, in the cavity connected to the water pipe of the water tank.
