What engines are equipped with each model of Chang'an Star?

"New Chang'an Star" will be equipped with JL473Q engine with a displacement of 1243ml. Although its displacement is slightly smaller than that of the 1298ml model of Chang'an Golden Bull Star, the output power has increased significantly.The maximum power of the new engine is 72kw, and the maximum power of Chang'an Taurus is 60kw.

Chang'an Star: 6350 is a 472 engine, 6350A is a 465Q1 carburetor car, 6350B is a 474 engine, 6350C is a 465Q5 engine, 6371A is an upgraded version of 6350C, front bumper and rear bumper and 6350C Different. 6 stands for a van, and 371 stands for its total length of 371 cm.

There are 3 kinds of engines. They are 465Q539KW and 474Q760KW respectively. 46616V51KW.

The engine of Chang'an Star 6363 is JL466Q1 engine.

The body size of the new Chang'an Star is 3980/1620/1890mm, the wheelbase reaches 2560mm, which is 210mm longer than the first generation of Chang'an Star.

Which side of the CB10 engine tile mouth

1. General connecting rod tiles, all The same direction as the fuel injector, because the side pressure of the fuel injector is high.So they are all towards the fuel injector. { Most}.

2. The original is like this: the piston is concave on one side of the oil nozzle; the tile mouth of the connecting rod is on the left from the front (this is related to the direction of crankshaft rotation and the position setting of the oil channel, such as the small tile oil channel hole above is in the most hungest place). I hope you can really understand, so that no matter what kind of car it is.

3. When the connecting rod tile is assembled, the upper and lower marks cannot be correct or wrong, the direction of the tile mouth cannot be reversed, and the screws need to reach the corresponding torque. The tile mouth of the connecting rod looks to the left from the front, which is related to the direction of crankshaft rotation and the setting of the oil channel position. The connecting rod tile notch is facing the direction of the oil pump, and the direction of the piston arrow and the direction of the connecting rod with words are facing the timing gear.

4. Yuchai 4102 engine connecting rod tile mouth should face the front of the vehicle.

5. Some engines have a groove similar to the valve on the top. When installing, according to the arrangement of the valve on the cylinder head (the intake valve is in front or the exhaust valve is in front); there is also a mark on the connecting rod. In general, the side with words faces the front end of the engine, or the groove with the connecting rod tile is facing the oil pump. It is best to disassemble it again and pay attention to the tile mouth. To.

6. The Great Wall, Yangchai. Generally, the connecting rod tile mouth of the engine and the large tile mouth are in the same direction, and the piston is generally marked forward. Some pistons will draw the direction of the flywheel, and the direction of the oil filter is the right one. You can see which side has a notch according to your own machine, and then which side to face.

What is the cause of Chang'an CB10 engine piston erosion

.The fuel injector works poorly. When the fuel injector has oil dripping, secondary injection, poor atomization, etc., the local temperature at the top oil of the piston is too high, and the thermal stress increases, resulting in erosion. 5. The engine caused an explosion.

The main reason why the engine burns oil is basically caused by the piston ring being stuck with carbon, which is also a common problem of many cars burning engine oil, and it is also the reason why many cars are overhauled to solve the problem of engine oil burning.

The piston gap is too large. If the vehicle is used for a long time, there will be insufficient combustion carbon accumulation on the piston ring. If it is not treated for a long time, it will cause the piston ring on the engine piston to be loosely sealed with the cylinder block, and the oil will easily enter the combustion chamber, causing oil burning phenomenon. If it is serious, it will also lead to The phenomenon of "exploding the cylinder" of the motive.

Causes for piston breakageThere are many. The following are the reasons for your reference: the temperature is too high - when the engine is running for a long time, if it runs at a high temperature, it may cause the piston to burn or break.

How to plug in the cb10 engine ignition coil

Open the ignition coil cover on the top of the engine; use the inner five-pointed wrench to remove the ignition coil fixing screw; remove the ignition coil power plug; use a screwdriver to gently Turn it up, take out the ignition coil; put in the new ignition coil and fasten the screw; connect the power plug and cover the top cover.

Wiring method: one end of the primary coil is connected to the low-voltage power supply (+) on the vehicle, and the other end is connected to the switchgear (power breaker). One end of the secondary coil is connected to the primary coil, and the other end is connected to the output end of the high-voltage line to output high-voltage electricity.

The five wires of the engine, the black wire is the magnetic motor stator ignition coil, connected to the socket of the igniter's two plugs, blue/white and green/white are the stator trigger coil, connected to the four plugs of the igniter, red (should be pink) and yellow are the lighting coil, connected to the rectifier.

The first picture black/red is the ignition coil output line, blue/white and green/white are the trigger coil output line. These three are connected to the igniter. If your original igniter plug is out, you can plug it in as shown in the figure below.

How to install the double camshaft of Chang'an Star CB10 engine?

Turn the camshaft, the large pump, and the crankshaft will turn their respective notations.Intermediate teeth, assemble the abc or 123 on the intermediate teeth with the camshaft, large pump, and the abc or 123 pair on the crankshaft respectively. After the middle wheel is in place, the three marks need to be checked. They must be completely in the middle to be correct.

Use a card to jam the timing wheel of the Chang'an Star 16v engine, which is convenient for proofreading the chain on the camshaft. Find the blue chain on the camshaft of Chang'an Star 16v engine. Point the blue chain teeth of the Chang'an Star 16v engine at the small dots on the camshaft.

The operation method is as follows: First, use the camshaft shaft to jam the camshaft to prevent the camshaft from jamming the timing chain during the timing chain proofreading process. Then use a wrench to loosen the screw on the camshaft to facilitate the later timing proofreading. Then open the top of the shaft on the back of the camshaft, otherwise it cannot be proofread.

Align the positioning pin hole on the sprocket with the positioning pin hole on the camshaft, and then install the sprocket on the camshaft. The tightening torque of the camshaft sprocket bolt is 20N-; m; lubricate the timing sprocket and chain with oil. Turn the crankshaft twice to check whether the engine timing mark is aligned.

The crankshaft tooth mark of the engine of this car is a point. There are two points on the camshaft. It is possible to connect the three points into a line. The crankshaft must be at the upper stop point, or look at the timing shell mark, and the arrow is connected into a line.

Why does the new Chang'an CB10 engine anti-heat?

1. Improper configuration of the heat dissipation system. According to the information on the official website of Chang'an Automobile, the reason why the Chang'an 4500 is replaced with a new engine and the high temperature is that the heat dissipation system of the new engine is improperly configured and used, resulting in poor heat dissipation effect, and the heat generated by the engine cannot be effectively dissipated, causing high temperature problems.

2. The water temperature of the Chang'an Star engine is high, but the actual temperature is not high. It is possible that the water temperature sensor is broken, because the actual temperature is not good. The water temperature sensor detects the temperature of water.

3. From a microscopic perspective: ΔH=E absorption-E release (microscopic), in which: E absorption indicates the total energy absorbed when the reactant breaks the bond, and E release indicates the total energy released when the product becomes a bond; ΔH is "+" to indicate the heat absorption reaction, and ΔH is "-" to indicate the exoactive reaction.

4. There is a problem with the ternary catalyst. The screw is loose due to the installation that is not installed well. Check whether the ternary catalyst is blocked, and it is best to do a comprehensive maintenance of the engine. In addition to replacing the spark plugs and ignition coils, it is also necessary to check and remove the carbon in the combustion chamber.

5. And the heat of the reaction must be under isothermal conditions, because the reactants and products constitute a whole system.

6. The common cylinder pad erosion is caused by high-temperature and high-pressure gas impact cylinder pad, resulting in cylinder leakage, lubricating oil and cooling water. When an erosion cylinder pad failure occurs, the engine power decreases and the cylinder pressure is insufficient; the exhaust pipe discharges, and the cylinder pad should be replaced immediately. After the car is replaced with the cylinder pad, there will be a certain devaluation of the car.
