Is there any difference between Yuchai 6k and 6MK engines? Or what are the technical improvements?

1. Compared with Yuchai 6mk engine, Yuchai 6mk engine and 6l engine are more fuel-efficient.

2. The technology used in Yuchai engine The Yuchai engine adopts an integrated cylinder head design, and the intake pipe is integrated into the cylinder head. The structure is very compact, and its high efficiency and reverse cooling technology.When the coolant cylinder head flows into the cylinder block for cooling, its flow rate is large and more efficient, thus solving the high load problem when the natural gas engine warms up.

3. Very good. The 6MK model adopts a fuel-saving design with four valves per cylinder, and the engine structure adopts an integral cylinder head, which adheres to the greatest advantages and characteristics of Yuchai's traditional product quality and stability. Yuchai's new generation heavy engine YC6MK375-40 won the 2012 "Quality Engine of the Year" honor.

4. The displacement is different: 6K10 and 6K12 displacement 2113 are 10 liters and 12 liters respectively. The displacements of these two are different, among which the displacement of 6K12 is more than that of 6K10.

Which one is more powerful, the engine of the train or the plane?

In its most powerful configuration, this monster generates a total of 1360,000 Newtons of traction with four jet engines, which is 5 times the most powerful train engine in the world! Now, what's more terrifying is that there is such a plane that can pick up and carry the above-mentioned locomotives and carry 500 slightly overweight passengers by the way.

The research and development capacity of aircraft engines is very poor, about 40 years behind the world's advanced level. The car engine is stronger, but it is still behind Germany, Japan and the United States. Personally, I think about 15 years. The internal combustion engine of an ordinary locomotive is similar. However, the core technology of the high-speed rail engine is still not good, and we have to rely on it.

The engine used by the train is piston-type, which used to burn coal, then burn oil, and now use electricity. During World War II, the engine of the aircraft was piston type, and later it was replaced with turbojet, turbofan, turboprop and other engines.When changing the engine of a fighter plane, some people say that there is a new engine, and the piston engine can be thrown into the trash can.

The plane flies fast because of the low air pressure, small air density, small resistance, and no substantial friction. Moreover, the driving force and thrust of the plane is quite large, which is not comparable to the locomotive of the train at all. As for the flight route, several people on the top of the flight route are lays, and the plane does not fly in a straight line. But it has nothing to do with speed.

Horsp represents the power generated per unit of time, which can also be understood as the magnitude of the power. In trains, horsepower is usually used to describe the output power of the train engine, that is, the amount of power generated by the engine over a certain period of time. Greater horsepower means more powerful power.

What does the train power rely on

1. Internal combustion locomotives, the front of the car is equipped with a diesel engine, which is fueled by diesel. The front of the electric locomotive is equipped with a traction motor, which is powered by electric current. Powered by the contact network.

2. Most trains use electricity and use electricity as the power source. Of course, there are also a few trains that burn diesel or coal.Trains are generally divided into electric locomotives, internal combustion locomotives and steam locomotives. Electric locomotives use electricity as the source of power. The locomotive itself does not have a prime mover, and mainly relies on the current sent by the pick-up contact network as energy.

3. Electric locomotive The power of electric locomotive is electricity. The electric locomotive itself does not have a prime mover. It receives the current sent by the contact network as energy, and the wheels of the locomotive are driven by the traction motor.

4. There is a high-power diesel engine in the internal combustion locomotive, which is used to drive the synchronous main generator to generate electricity and use this electricity to drive the traction motor. The train has a traction motor on each axle, and the motor is used to drive the train.

What is the basic structure of the train and the functions of each part?

Engine: The engine is the power device of the car.It is composed of 2 major mechanisms and 5 major systems: crank connecting rod mechanism; gas distribution mechanism; fuel supply system; cooling system; lubrication system; ignition system; start system.

Railway vehicles are generally composed of car body and bottom frame, hook decelerator, running part, braking part, and in-car accessory part. Railway: Railway refers to the transportation route for trains to run. It consists of roadbeds, roadbeds, sleepers and steel rails, including bridges, tunnels and various auxiliary facilities along the route. Railways are also called railways.

Locomotive body, wheels, power system, control system, brake system. The locomotive is the front part of the train, which is composed of multiple components. The locomotive body is the main part of the locomotive, which is welded by steel plate. It is equipped with cab, engine room, transmission room, electrical room, etc. inside.

Generally speaking, the basic structure of the vehicle consists of five major parts: the body, the undercar, the running part, the hook buffer device and the brake device. The body is the part of the vehicle for loading goods or passengers, and it is also the basis for installing and connecting other components of the vehicle.

What is the power principle of train internal combustion engine?

The fuel burns in the cylinder, and the high-temperature and high-pressure gas generated expands in the cylinder, pushing the piston to move back and forth. The connecting rod drives the crankshaft to rotate to do external work, and the thermal energy of the fuel is converted into mechanical work.

Both internal combustion locomotives and electric locomotives were born at the end of the 19th century. The working principle of the internal combustion locomotive is to let the diesel or gas fuel burn in the cylinder, and use the high-temperature and high-pressure gas generated during combustion to push the piston and drive the wheels forward.Electric locomotives, on the other hand, use electricity to turn the wheels through electricity.

There is a high-power diesel engine in the internal combustion locomotive, which is used to drive the synchronous main generator to generate electricity, and use this electricity to drive the traction motor. The train has a traction motor on each axle, which relies on the motor to drive the train, so the internal combustion locomotive relies on direct transmission, not the engine like the car. It directly acts on the wheels.

Steam locomotives and internal combustion locomotives are two completely different models. How can internal combustion locomotives burn coal? Internal combustion locomotives are for drinking oil! ~ The internal combustion locomotive drives a large generator to generate electricity through the diesel engine, and then drives the electric motor. The motor rotates and then runs with the car.

The internal combustion locomotive is made of diesel.If coal is used, it must first go through the process of "coal into oil", and the coal can be turned into oil before it can be supplied to internal combustion locomotives. It is a high-power diesel engine.

The power of the electric locomotive is electricity. The electric locomotive itself does not have a prime mover and relies on the current sent by the contact network as energy. The power of the internal combustion locomotive is diesel, and the generator is driven by the diesel engine. The power of the steam locomotive is coal, and the train uses coal as raw material. Boiling water produces steam, which is used to promote the reciprocating movement of the piston in the cylinder.
