Petroleum products HS code insights

Specifically, the engine can be classified in the following ways: according to the ignition mode.According to the ignition method, it can be divided into ignition engines (gasoline engines, liquefied petroleum gas engines and dual-fuel engines) and compressed combustion engines (diesel engines and heavy oil engines). Classify according to the working cycle.

The types of automobile engines can be divided into naturally aspirated and turbocharged according to the working mode of the intake system. According to the cylinder arrangement, it is divided into in-line engine, V-type engine, W-type engine and horizontally opposed engine, etc. Naturally aspirated engine: air enters the cylinder by the suction of the piston.

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.

●Classified according to the cylinder arrangement: Internal combustion engines can be divided into single-row, double-row and three-row according to the different cylinder arrangement. The cylinders of the single-row engine are arranged in a row, generally arranged vertically, but in order to reduce the height, the cylinders are sometimes arranged in an inclined or even horizontal one.

Classified according to the fuels used are: gasoline engines (referred to as gasoline engines), diesel engines (compressed combustion engines) and special fuel engines (such as natural gas, hydrogen and alcohol engines). Classified according to the cooling method: Internal combustion engines can be divided into water-cooled engines and air-cooled engines according to different cooling methods.

What is the working principle of the rotor engine

The working principle of the rotor engine is: the rotor engine, like the engine in the car, is an internal combustion engine, but its working method is completely different from that of the traditional piston engine. In a piston engine, four different operations must be completed alternately in the same space (cylinder) - intake, compression, combustion and exhaust.

Working principle: Generally, the engine is a reciprocating motion engine, and the workWhen the piston does a reciprocating linear motion in the cylinder, in order to convert the linear motion of the piston into rotary motion, the crank connecting rod mechanism must be used. The rotor engine is different. It directly converts the combustion expansion force of combustible gas into driving torque.

The principle of the engine is to immediately convert the ignition expansion force of the combustible gas into driving torque. Compared with reciprocating engines, rotor engines eliminate useless uniform linear motion, so rotor engines of the same power have great advantages in smaller size, lighter net weight, lower vibration and noise.

Most engines are reciprocating engines. When working, the piston makes a linear reciprocation in the cylinder. In order to convert the linear motion of the piston into rotational motion, the crank slider mechanism must be used. The working principle of the rotor is to directly convert the energy of the combustible gas into driving torque, thus driving the engine.The monthly salary is more than 3,000 yuan.

Rotor The role of the rotor is like the piston and connecting rod in the reciprocating engine. In order to make the shape of the inner package route, it is designed into a triangular cone (the grooves on the side are related to the compression ratio). The intake and exhaust ports will automatically open and close according to the state of rotation, so that it has both The function of the exhaust door.

Usually, a rotor engine is a simple mechanism in which the rotor and the eccentric shaft rotate relative to each other. The number of teeth of the inner ring of the rotor is 51, and the number of teeth of the central axis is 34. Therefore, the crankshaft rotates three times, and the rotor only rotates once (51-34=17, 11 Mazda rotor engine working principle: 1.
