What is the difference between Yuchai Power and Yuchai Boat Power

1. According to the introduction of Yuchai Ship Electric Engine and Yuchai Machinery Co., Ltd., the two are different and belong to different companies.

2. Both diesel engines are better, and there is not much difference. Introduction to diesel engine: Diesel engine is an internal combustion engine that uses diesel as fuel. The diesel engine is a compressed ignition engine, and it is often called the Diesel engine after the main inventor Dissel.

3. Yuchai has four major business sectors: vehicle power, marine electric power, general power and new energy power, and has built excellent independent research and development capabilities, integrated application capabilities, rapid market response capabilities, first-class production and manufacturing capabilities, high-quality customer resources and a complete marketing service network.

4. Different concepts: Yuchai power usually refers to the output power of the engine, that is, the maximum power that the engine can output, while Yuchai power refers to the total amount of energy consumed by the engine during operation.

What are the engines of Yuchai 20 liters or more

1. There are 489 Yuchai engines on sale, some of which are listed as follows: Yuchai YC4S160-50160 horsepower 8L Guowu diesel engine.Yuchai YC4FA130-50130 horsepower 3L Guowu diesel engine. Yuchai YC4E160-56160 horsepower 26-liter Guowu diesel engine. Yuchai YC4EG185-50185 horsepower 73-liter Guowu diesel engine.

2. Yuchai YC4S170-50170 horsepower 8L Guowu diesel engine. Yuchai YC6JA240-50240 horsepower 87L national five diesel engine. Yuchai YCK15650-60650 horsepower 15L national six diesel engine. Yuchai YC4S150-50150 horsepower 8L Guowu diesel engine. Yuchai YC4EG200-50200 horsepower 73-liter national five diesel engine.

3. There are three types of engines used by bj40, which are 20-liter turbocharged gasoline.The 20-liter turbocharged diesel engine and the 23-liter turbocharged gasoline engine have 150 horsepower and 350 Nm. The maximum power speed of the engine is 4,000 rpm, and the maximum torque speed is 1800 to 2800 rpm.

4. There are 489 Yuchai engines on sale, some of which are listed as follows: Yuchai YC4S160-50 160 horsepower 8L Guowu diesel engine Yuchai YC4FA130-50 130 horsepower 3L Guowu diesel engine. Yuchai YC4E160-56 160 horsepower 26L Guowu diesel engine. Yuchai YC4EG185-50 185 horsepower 73L Guowu diesel engine.

5. Yuchai YC6JA180-50180 horsepower 87-liter Guowu diesel engine.Yuchai YC4S130-50130 horsepower 8L Guowu diesel engine Yuchai YC4FA115-40115 horsepower 3L Guowu diesel engine. Yuchai YC6J180-33180 horsepower 5L Guosan diesel engine.

6. The common model of Yuchai 1400 horsepower engine is YC6MK1400N. This engine belongs to the high-power series of Yuchai, which is widely used in heavy commercial vehicles, construction machinery, ships and other fields.

What is the cylinder pressure of Yuchai 4108 engine

1, brand Yuchai model YC4108C fuel diesel number of strokes 4 number of cylinders 4 standard speed 1500 (rpm) continuous output power 40~ 50 (kw) rotation counterclockwise application range marine, power generation, vehicle, engineering machinery.

2. The power of Yuchai 4108 supercharged engine is about 115KW, and the horsepower is 140 horsepower.

3. The lack of power of Yuchai engine is caused by the following reasons. Insufficient cylinder pressure: There are several kinds of reasons that usually lead to insufficient cylinder pressure of internal combustion engines. The valve seat is corroded, not sealed or fallen off; the valve spring is too soft and does not work well; the cylinder pad is not sealed and eroded; the piston ring is bitten or opposite; the piston and cylinder gap is too large.

Yuchai Marine Engine and Cummins Marine Engine have the same horsepower and usefulness, which one is fuel-saving

1. This is only relative. Cummins is suitable for running in plain areas and saving fuel. The cylinder diameter of Yuchai engine is larger than Cummins under the same power, and the torque is large. It is suitable for use in bad road conditions such as dump trucks in mountainous areas. Pulling the same weight, with the same gearbox and rear axle, the Yuchai engine starts faster and runs faster than Cummins waste oil.

2. Durability and fuel economy must of course be Cummins' engine. Cummins 190 horsepower is a 6-cylinder B series model.The cylinder diameter is 102mm, and the Yuchai 180 horsepower should also be a 6-cylinder engine, and the cylinder diameter is 105mm.

3. If it is the same 10 tons, with the same horsepower, the fuel consumption of Cummins is slightly lower, and the consumption of Yu diesel is slightly higher. Cummins is recognized as fuel-saving.

4. It is better to use NTA855 for marine generators. Cummins' unit has low fuel consumption, low failure rate and large power. Compared with Yuchai, Cummins' unit has high reliability to a certain extent.

5. Take Cummins as an example: The Cummins engine has always been famous for its fuel saving. As an engine that feels lukewarm to use, its fuel saving is its biggest feature, so it is generally installed on logistics trucks, which can save a lot of money for long-distance driving, but the explosive power should However, it is not as powerful as the Yuchai engine.

6. Yuchai has always been the leader of domestic diesel engines, and the sales volume has always been the first in domestic diesel engines! And it ranks second in the world's diesel engine sales! Second only to the sales of Cummins engines in the United States, it can be seen that Yuchai has not only gained wide recognition in China, but also gained high popularity in the world.

How about the 1600 horsepower host of Yuchai Ship

1. The acceleration is different. The acceleration of 140 is still inferior to that of the real 160. The fuel consumption is different. The fuel consumption of 140 is still narrow compared with the real 160. Top: 140 Bottom: 160 The climbing ability is different. The climbing ability of 140 is still poor compared with the real 160.

2. Yuchai 1200 horsepower ship diesel engine has 400 rpm. The main diesel engine of container ships and passenger ships is a four-stroke machine, with a speed of three or four hundred rpm, which is irreversible. It needs to reduce the gearbox to reduce the speed of the host to a propeller or a pitch paddle.

3. This is only relative. Cummins is suitable for running in plain areas and saving fuel. The cylinder diameter of the Yuchai engine is larger than Cummins under the same power, and the torque is large. It is suitable for use in bad road conditions such as dump trucks in mountainous areas. Pulling the same weight, with the same gearbox and rear axle, the Yuchai engine starts faster and runs faster than Cummins waste oil.

4. Select according to the host power and rotation speed. Matching of marine gearbox and marine diesel engine: The transmission capacity of the marine gearbox should be greater than the ratio of the rated power to the rated speed in the parameters of the diesel engine.

5. It is caused by friction between the piston ring and the cylinder mirror during normal wear, also known as friction wear. The maximum wear position of the cylinder mirror is near the first ring when the piston is at the upper stop point, which often forms an obvious step.

6. Yuan. To calculate the fuel consumption of an 800-horsepower engine for ships, you need to know the specific fuel consumption rate of the engine and the local fuel price.
