Yangtze River 750 turns on the headlight engine shakes

1. The headlight engine shake may be caused by insufficient power generation of the generator or battery power loss. Check whether the generator belt is aging or too loose. The reason why the engine shakes when the headlights are turned on: 1.

2. The headlight engine shaking may be caused by the low power generation of the generator or the lack of power of the battery. It is necessary to check whether the belt of the generator is aging or too loosely adjusted.

3. Not only turn on the headlights, but also turn on other larger electrical equipment. At this time, the power generationThe increase increases the load of the engine (the power of the engine is very low at idle speed), resulting in jitter. A high-power engine is much better. The solution is to stabilize the idle speed when turning on the headlights.

4. If there is no problem with the voltage of the generator, turning on the headlight is equivalent to increasing the load to the engine. It is normal for the idle speed to drop, especially for vehicles with a long service life. If the carbon in the intake system and engine combustion chamber can be removed, this shaking phenomenon may be alleviated.

5. First of all, the most common reason for car shaking is that the throttle is too dirty or the fuel injector accumulates too much carbon. When the engine accumulates too much carbon, the gasoline sprayed by the cold-start injector will be absorbed by a large amount of carbon, resulting in thin cold-start mixture and difficult start-up. In this case, it is easy to drive only when the carbon-absorbing gasoline is saturated.

6. The reasons for the serious shaking of the engine are excessive internal carbon accumulation and lack of cylinder in the engine. The specific reasons and solutions are as follows: excessive internal carbon accumulation: carbon accumulation occurs in the valve and air intake of the engine, which can absorb an appropriate amount of fuel and cannot achieve the required power performance, resulting in the car to start shaking. The solution is to clean the system.

There are several types of Yangtze River 750 engines

According to the official data, the engine displacement of this car has reached 643cc, and the parallel twin-cylinder water-cooled 8-valve double-top camshaft design, with a maximum power of 52kW (70 .7Ps)/8500rpm, the maximum torque is 62Nm/7000rpm, and the German BOSCH electric injection system is adopted for oil supply, and the power performance is very strong.

Hello, there is not much difference in appearance, mainly due to different engine models, different engine structures, and different output horsepower. The early Changjiang 750 had a voltage of 6 volts, 22P horsepower, and no electric start. Later, the 24P version is a 12-volt voltage, an external distributor, a side valve, and an electric start.

Now the revived Changjiang 750 is equipped with a spring breeze 650cc displacement engine. The extreme output of this twin-cylinder engine can reach 52 kilowatts, which is the level of more than 70 horsepower. The peak torque of 62 Nm is also very reliable. The water-cooled heat dissipation module can meet the needs of long-distance driving.

The Yangtze River 650 has now been resumed, using the parallel twin-cylinder 650 engine of Spring Breeze. The original Yangtze River 750 is a horizontally opposed engine, which is the same as the BMW motorcycle. In fact, it is an imitation of BMW.

Changjiang 750 has strong power performance. It adopts a carefully designed multi-mode motor, with a maximum power of 240kw and a maximum torque of 3000nm, so that the vehicle has enough power under any road conditions and meets the owner's high driving safety performance. Requirements.

Depending on different models, there are reverse gears and some without reverse gears. The early engine cylinder head was cast iron without reverse gear, and later the engine cylinder head was made of aluminum alloy, which was double-started.

Changjiang 750 is easy to turn off in the first gear

1. There are three main reasons. If it is a motorcycle with a side bracket take-off and landing insurance, the engine will turn off when you turn on the bracket and hang up the gear.

2. Add some throttle. Many novices dare not refuel when starting, which is also an important reason for starting the engine to turn off. Maybe you will feel that you are boomming the accelerator? That's because the clutch is not loose to the linkage point or is too slow. When the vehicle moves, the clutch can be released at a steady speed to start smoothly.

3. Six reasons and solutions that are easy to turn off in the first gear; engine cylinder carbon accumulation is serious. Solution: Clean up the accumulated carbon. The engine power is insufficient. Solution: Go to the repair shop to find out the cause and repair the engine. The engine gasket is aging. Solution: Find a professional to replace the machine mat. Lack of tank.

Which of the 24-horsepower or 32-horsepower Changjiang 750 engine has more faults? Why

1. The main reason is that the engine model is different, the engine structure is different, and the output horsepower is different. The early Changjiang 750 had a voltage of 6 volts, 22P horsepower, and no electric start. Later, the 24P version is a 12-volt voltage, an external distributor, a side valve, and an electric start.32P is also a 12-volt voltage, but it is a top valve, click to start.

2. Good. The 32-horsepower one consumes more power and cools faster than the 24-horsepower one. The two only have different power and have nothing to do with durability. The Yangtze River 750 faithfully retains almost all the features of the BMW R71.

3. There is a big difference. The 24-horsepower diesel engine model is L24 or ZS1115 diesel engine. Their cylinder liner diameter is 115 m, while the 32-horsepower diesel engine model is 1130, and the cylinder liner diameter is 130 m. The diameter is different, the combustion volume is different, the cylinder block is different, and the greater the horsepower, the higher the work efficiency.
