Tianjian and Feizhi engine one Is it like?

The biggest difference is that the names of the two cars are different. Tianjian 150 is obviously released later than Feizhi, and it is the same engine. Tianjian is a low-configuration version of Feizhi, which is a shrinking version of Feizhi 150. If you have more money, buy Feizhi 150, and if you have less money, buy Tianjian 150.

Engine displacement: Tianjian 150Z is equipped with a 149 cc single-cylinder air-cooled engine, while the Feizhi 250 is equipped with a 249 cc single-cylinder air-cooled engine.Horsepower: The maximum horsepower of Tianjian 150Z is about 15 horsepower, while the maximum horsepower of Feizhi 250 is about 23 horsepower.

The configuration is different. Tianjian 150 air-cooled engine, displacement of 150cc, maximum horsepower of 16PS, maximum torque of 17N.M, and maximum power of 3KW. The displacement of the Feizhi 150 air-cooled engine is 155cc, the maximum horsepower is 16PS, the maximum torque is 17N.M, and the maximum power is 13KW. The price is different.

Universal. The Sky Sword King is a motorcycle under the Yamaha brand, which has been replaced by the modern Feizhi as early as the National Three Era. Feizhi is an upgraded version of the Sky Sword King, which shows that the former abbreviation is universal. Yamaha's new Feizhi 250 was officially announced on the official Weibo on April 20, 2018.

The displacement of Tianjian 125 is 125cc, the displacement of Feizhi 150 is larger than that of Tianjian 125, and the speed of Feizhi 150 is faster. In terms of engine. The Tianjian 125 engine is a Yamaha ybr engine, and the Feizhi 150 engine is an air-cooled OHC four-stroke two-valfe single-cylinder engine. The Feizhi 150 engine is better than the Tianjian 125 engine, and the Feizhi 150 accelerates faster.

Where is the oil channel of the Yamaha Tianjian 125 engine

1. Hello: Write down the cylinder head. The oil channel on the engine cylinder head is at both ends of the cylinder head, and you can see an oil hole in each, one One is the main oil channel, and the other is the main oil channel. For other oil channels, after you remove the axle, you can see the oil channel on the bearing seat.

2. Most Suzuki pedal motorcycles have two ports to put oil, one under the bottom of the right side of the engine, and the other at the front position at the bottom of the left, and the screw mouth is facing the left.

3. In Yamaha Tianjian 125 motorcycle, the oil switch position can be divided into two situations. In general, the oil circuit switch is on the left, and the position is designed uniformly. It is not left or right. You only need to choose according to your own habits. In this case, you can find it under the safety helmet or on the right side of the engine.

4. There is a large plug at the bottom right of the engine, which is equipped with an organic oil filter. In general, during regular maintenance, the oil filter can be removed for inspection and cleaning. Generally, as long as the qualified oil is replaced regularly, it will not be blocked and does not need to be disassembled and cleaned frequently.

The working principle of Tianjian YBR engine, please summarize, thank you

1. This single-cylinder 149cc electric injection engine with "Chuangxin Technology" is the power source of YBR150Z. Its original roller rocker arm and advanced balance shaft technology enable the engine to achieve high efficiency and low vibration.The test drive is carried out around Fuxian Lake. Although the light rain continues, it has little impact on the performance of YBR150Z.

2. Yamaha Tianjian YBR150Z is designed to take into account the load of goods. The seat is relatively low and flat, integrated with the straight rear shelf, which is convenient to load objects. The shock absorber is equipped with a dustproof cover, etc., to be more suitable for bad road conditions. Yamaha Tianjian YBR150-6 bracket adopts a large-diameter steel pipe diamond bracket with simple, rigidity and excellent strength balance.

3. Yamaha YBR250 adopts SOHC engine. It can effectively save fuel, theoretically save about 5% of fuel consumption, and maintain the comprehensive fuel consumption at 8L/100km. The factory's conservative maximum speed is 123km/h, and some have run 140km/h.

4. Power StartThe type of machine is air-cooled 4-stroke SOHC2 valve, the number of cylinders is single cylinder, and the total exhaust volume is 123cm cubic meters. Due to the optimal design of various sizes of the car body, the stability of safe walking is achieved from low speed to high speed, and you can also walk at will in curves, achieving the characteristics of lightness.

5. As for China, we can hardly see it, but we can order the Chunfeng CF650, the water-cooled electric injection twin-cylinder 650CC engine. Build YAMAHA's YBR250 Tianjian "King", single-cylinder air-cooled electric injection 250 engine. Jialing JH600 single-cylinder water-cooled electric injection 4-bal valve 600CC engine.

The Yamaha Tianjian K engine rattles when running

1. GasExcessive door clearance: Excessive valve clearance will cause loud engine noise, and the noise will be more obvious when the accelerator is increased. The solution is to let the gas distribution mechanism adjust the valve gap.

2. The reasons for the sound are: the gap between the piston and the cylinder wall is too large; the piston pin assembly or the connecting rod bearing assembly is too tight; the gap between the rod and its guide hole is too large; the contour of the gas distribution cam is worn; sometimes, the starting grip is loose and the pulley to sound (obvious when the speed changes).

3. There are two cases of scoring: it will sound in idle gear, that is, the piston ring is worn and needs to be replaced.

4. Tianjian is a motorcycle of Chongqing Construction Yamaha Motorcycle Company. The reason why there is an abnormal sound in the valve after 20 minutes of running is that the oil is inappropriate, and the oil viscosity is too high, which will lead to insufficient lubrication during engine operation, resulting in friction, resulting in abnormal noise.

5. If the valve gap is too large, it is most likely to cause abnormal noise, which mainly comes from the collision between the rocker arm and the valve. The gap between the small head of the crankshaft connecting rod and the piston pin is too large, and its left and right swing is too large, and the connecting rod is worn, resulting in a sound.

6. The effect is not guaranteed. The ruler is not expensive. Mine is the tool I bought and adjusted it by myself according to the method searched on the Internet. The effect is good. You can also change the engine oil to 10w-40, or 15w-40 model four-season oil. The engine oil must be authentic. It's best to go to the after-sales service to change it. Don't worry.
