Read an article, what are the forms of automobile engines

1As we all know, the engine works by burning mixed gas, so the way of mixing with fuel and air is called the oil supply method of the engine. The oil supply method is also called the fuel injection method, which is mainly divided into manifold injection (electric injection), in-cylinder direct injection and hybrid injection.

2. The so-called monomer means that there are several cylinders, and there are several corresponding monomer oil pumps. Compared with the traditional mechanical oil pump, the monomer pump system has two main differences in structural form.

3. However, mechanical supercharging is simply driven by the rotation of the crankshaft. As long as the engine works, the mechanical supercharging will work synchronously. The higher the engine speed, the stronger the mechanical supercharging ability, the stronger the power, and there is no lag at all. The power output is smooth, and the large-displacement self-priming engine. Comparable to.

four, three-cylinder engine model recommendation: Angola intake stroke Driven by the crankshaft, the piston moves from the upper stop to the lower stop. At the same time, the intake valve is open and the exhaust valve is closed.

What kind of car engines are there? What's the difference? What kind of performance is good!

Four-stroke (four-stroke) engine, two-stroke (two-stroke) engine; single-cylinder, two-cylinder, multi-cylinder (three-cylinder or more) engines according to the number of cylinders; according to the cooling method, it is divided into water-cooled and air-cooled; according to the arrangement method, it is divided into in-line L-type, H-type, W-type, V-type arrangement, etc. Wait.

Car engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrid power according to different power sources: diesel engines The advantages of diesel engines are large torque and good economic performance.

The H-type engine is arranged horizontally, the center of gravity of the whole vehicle is very low, and the vehicle drives more smoothly. In addition, the torque generated by the pistons on both sides of the engine cancels each other, which reduces the vibration of the engine and reduces noise. Subaru uses this kind of engine.

Under normal circumstances, cars equipped with diesel engines have large torque, simple structure, high reliability and good fuel economy, and are mostly used in large vehicles.

According to different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle electric motors and hybrid engines, etc. 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.

Therefore, the types of automobile engines are mainly as follows: (in-line L, V-type, horizontally opposed, W-type and rotor engine (triangular piston engine, RE) in-line (line) is abbreviated as L, such as L4, L6, etc., and the general exhaust volume is less than 2000cc Most of the engines adopt this kind of structure.

The difference between an automobile three-cylinder engine and a four-cylinder engine

The number of cylinders is different: a three-cylinder engine has three cylinders; a four-cylinder engine has four cylinders. The structure is different: the structure of the three-cylinder engine is simple, small in size, light in weight and easy in layout; the structure of the four-cylinder engine is relatively complex.

The difference between the three-cylinder engine and the four-cylinder engine of a car: the number of cylinders is different: the three-cylinder engine has 3 cylinders; the four-cylinder engine has four cylinders. Different weights: three-cylinder engines are small and lighter; four-cylinder engines are larger and heavier than those.

The difference between a three-cylinder engine and a four-cylinder engine is that the displacement and the number of cylinders are different. The displacement is different: most of the displacements of 3-cylinder engines are less than 1 liter;The displacement of a 4-cylinder engine is 1 to 5 liters. The number of cylinders is different: the number of cylinders in a 3-cylinder engine is 3; the number of cylinders in a 4-cylinder engine is 4.

The structure of a three-cylinder engine and a four-cylinder engine is different, and the cost is also different. The price of the three-cylinder model is cheaper than that of the four-cylinder model. If the three-cylinder turbocharged model is compared with the four-cylinder naturally aspirated model, the price of the three-cylinder model will be more expensive.
