Who can tell me what kind of engine CY4102-C3B is?

Represents the model meaning of the diesel engine: 1-Product change code: missing position, basic type;X, new type; B, R, generation change logo 2-Cylinder number (digital) 3-Cylinder arrangement form: missing position, series; V, V-shaped arrangement. 4-Cylinder diameter (mm). 5- Some series of special codes.

If it is a Guangyang GY6 engine, you can buy a completely brand-new original engine for 600-700. It's true that you can buy it. I'm in Changzhou. My friend drove it. I've done it. In Changzhou, but if you drive, you will hang a trademark of Changzhou Guangyang on the facade. It's too easy to buy accessories and the whole machine in Sanqiaotou Auto and Motorcycle Market.

The role of the car engine. The car engine is a device that powers the car. It is the heart of the car and an energy conversion device. Its function is to expand the thermal energy of gasoline (diesel) through combustion in the sealed cylinder, pushing the piston to work and convert it into mechanical energy.

I). Check the ignition timing. Generally, check the starting engine, raise the coolant temperature to 80℃ and accelerate rapidly. If the speed cannot increase immediately, feel stuffy, or there is a sudden sound in the exhaust pipe, indicating that the ignition is too late; if there is a similar metal knocking sound, it means that the ignition is too early.

What's wrong with the high temperature and low speed of the cy4sk251 engine?

1. As a result of excessive water temperature, first, it may be due to the lack of coolant of the vehicle. It is necessary to supplement the coolant after the water temperature cools down, and avoid replenishing at high temperature, which is easy to burn the skin; secondly, it may be due to the failure of the thermosulator, so that the cooling system cannot operate normally, and thirdly, it may be due to the heat dissipation fan. Insufficient rotation speed or malfunction.

2. If the throttle position transmitter is damaged, there will be phenomena such as not being able to add fuel and driving at a uniform speed.

3. Poor engine sealing; the crankshaft oil seal on one side of the engine fails and leaks air; the joint surface of the crankcase is leaking; the crankcase and the cylinder junction surface leaks or the piston assembly direction is wrong. ( 3) The reason for the engine flute spring valve: the flute spring valve is damaged;The rotary valve is installed in reverse, causing reverse spray. Two. The oil-rich mixture is too thick, causing the car to accelerate weakly at low speed.

How about the Chaochai cy4sk151 engine

1. This engine is good, 4 valves, 125kW. Both the dynamic and the economic type are relatively excellent.

2. Chaochai 4sk151 bump changer is better than second-hand engines in terms of cost-effectiveness, which can save more money. Chaochai 4sk151 bump replacement machine is better than second-hand engines in terms of maintenance convenience, and maintenance is more convenient and faster.

3. The engine is weak and the noise is loud and the vibration is loud. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc.The engine was first born in England, so the concept of engine also comes from English. Its original meaning refers to the kind of mechanical device that generates power.

4. The performance of Yunnei and Chaochai engines is basically similar! But Yunnei is more suitable for mountain roads! Chaochai is better for plains.

5, CY4BK151 gear shifting is occasionally not smooth, high fuel consumption, small horsepower, powerless to drive, loud noise, technology can't keep up and too many small problems, etc.

CY4102 engine common disease

1. The distance between the catheter exposed to the cylinder head plane is not standard, which may be caused by rocker arm impact or in-cylinder valve head impact.

2. The most serious thing is now because of the shaft in the pressure box.If the bearing is broken, resulting in the complete scrapping of the pressure box teeth and secondary variable speed, the manufacturer does not include it. Nanjun's common disease: water tank desoldering.

3. The engine is not suitable, and the firewood is suitable for running on flat roads and light load conditions. For year-round overload, it is recommended to choose Yunnei 4102, which is solid, durable and worry-free. Chaochai has more problems after 2 years of use. If you are unlucky, it will spend as much as you earn. Ha ha, I hope it will be helpful to you.

4. The fuel consumption of an empty car is seven or eight liters of oil. When carrying goods [under the standard quality], it is about eight liters of oil, and the overweight mass is two hundred percent of the fuel.

How about the cy4sk251 engine? Guowu

Chaochai cy4sk251 engine is of good quality, powerful and no noise.Chaochai 4SK has a large low-speed torque and harder to climb hills. You can drive in the second gear without refueling, and then you can drive in the third gear and the fourth gear without refueling.

Good. The technologically advanced Chaochai CY4SK four-valve series diesel engine is a new generation of high-quality diesel engine developed by Chaochai Company and AVL Company. It adopts electronically controlled high-pressure common rail, cooling EGR and SCR post-treatment. The quality can be guaranteed, the service life is long, and there is after-sales service, which is very good.

Aoling's new MRT is equipped with a full wood 490 national five engine 4B2-115C50.
