Each engine is a product handmade by a technician. The high-performance M139 is the most powerful mass-produced four-cylinder engine at present, with a power of 421 horsepower.

The Great Wall Haval 5T diesel engine is a high-performance engine with German technology. Its power output is smooth, low noise, energy-saving and environmental protection. SAIC GM 6T diesel engine is a high-quality power system with excellent performance and stability.

The fourth is Ford. Ford is also relatively advanced in turbocharged engines above 0T. Its 3T inline four-cylinder gasoline engine is very strong. For example, it is equipped with the domestic Focus RS. Its maximum horsepower is 350Ps and the maximum torque It is 440N.M.

Quanchai Quanchai was founded in 1949 and is currently the largest four-cylinder diesel engine research and development and manufacturing enterprise in China. It is the only listed company in the internal combustion engine industry in Anhui Province, and a key high-tech enterprise of the National Torch Program. The diesel engines it produces are powerful and the technology is at the leading level.

Acura 5T four-cylinder fuel engine Acura is very popular in the North American market, and can even compete with BBA. It is also one of the most popular luxury brands in the United States. The maximum output of this engine is 204 horsepower, and the peak torque is 260 Nm. The power performance is excellent, which can be called the strongest 5T fuel engine.

Honda has won the title of Ward's top ten engines 16 times. Honda's engines are as famous as Toyota's, especiallyThe 0L naturally aspirated inline four-cylinder engine developed by Honda has won many technical awards, and Honda Accord, Honda Civic and other models are also equipped with this engine.

What are the current mainstream engines in the market? What are they all?

According to different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrid engines. According to the working mode of the air intake system, it can be divided into four types: natural intake, turbocharging, mechanical supercharging and double supercharging.

At present, the models that can be seen in the domestic automobile market are basically front engines, that is, the engine is in front of the front axle.

There are many kinds of engines, and the working principle and purpose are also different.Most engines are aimed at outputting effective shaft power, that is, driving one or several axes to rotate. Such engines mainly include: piston type. Turbine type.

2 gas turbine engine. The most widely used. Including turbojet engines, turbofan engines, turboprop engines and turbine shaft engines, all have compressors, combustion chambers and gas turbines.

At present, most mainstream family cars on the market are L4. The disadvantage of in-line engines is low power. There is a certain angle between the cylinders of the V-type engine, which looks like the letter V from the side. Its advantage is that the inclined cylinder can shorten the height and length of the engine, thus leaving more space for the cabin.

Horizontal engine: the direction of the crankshaft and the body is at a right angle, and the vertical startMachine: The crankshaft is parallel to the direction of the car body. According to the structural form of the engine, it can be divided into: in-line engine: all cylinders are lined up side by side into a plane. V-type engine: the cylinders are arranged in a V-shape.

How does the Dewei D25pro engine perform in the domestic market?

Dewei D25pro engine adopts advanced German FEV technology, double overhead camshaft, four-cylinder sixteen valves optimized design, with high thermal efficiency and better power performance; it adopts a timing chain transmission system, with high engine stability and further reduced noise, for light truck For a comfortable driving experience for passenger cars.

According to an article by Truck Home, the power performance of the Yunnedeway D25Pro160 horsepower 5L Guoliu diesel engine fully meets the expectations of users. In addition, the engine's heavy-load climbing ability is well-known.

The power of Dewei D25pro is very good. Under the standard load, the vehicle is very fast in terms of starting, speeding up and overtaking, and the partners who run together can't catch up with me. The engine adoptsDouble overhead camshaft technology, large low-speed torque, good climbing performance, particularly strong power output, and the transportation efficiency is still very good.

There is no problem with the quality. I have been using it for three years, and there has been no malfunction. It is good to drive. The four-velve engine is much better than the two-velve engine. The key is to save fuel consumption. The price is not bad, not expensive.

The Dewei engine is still quite resistant to manufacturing. I specialize in pulling equipment. The engine is Dewei D25, which is the national six. The technical level is relatively mature and reliable. The round trip from Tongzhou, Beijing to Wuqing, Tianjin is about 80 kilometers, which is quite fast from the start and the highway, and it is not bad to drive.

The quality of Dewei engine is recognized by many users. Now the Dewei engine meets the national six emissions.Standard, and it has also been lightweighted. The sprocket chamber and sprocket chamber cover of the Wei engine are made of cast aluminum material. The same state mass is much lighter than that of the gear transmission engine, which can attract a lot of goods.
