What are the classifications of car engines?

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

Car engine classification: according to the power sourceDifferently, 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.

Diesel engine Diesel engine is an engine that burns diesel to obtain energy release. Is it by the German inventor Rudolf? Rudolf Diesel invented it in 1892. In memory of this inventor, diesel is represented by his surname Diesel, and the diesel engine is also called Diesel engine.

The classification of automobile engines can generally be divided into three categories, such as internal combustion engine, electric motor and gas turbine engine. Internal combustion engine and internal combustion engine refer to the main power device that uses the thermal energy of the internal combustion engine to make full use of the energy of the fuel to drive the car.According to the different types of fuel, internal combustion engines can be divided into gasoline engines, diesel engines, etc.

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.

Engine classification

Gasoline Engine Gasoline Engine is an engine that uses gasoline as fuel. Due to the small viscosity and rapid evaporation of gasoline, gasoline can be sprayed into the cylinder with a gasoline injection system. After compression to a certain temperature and pressure, it is ignited with a spark plug to expand the gas.

Engine type: According to the fuel usage of the engine, the engine can be divided into two types, one is a gasoline engine and the other is a diesel engine. The volume of the gasoline engine is relatively small, the mass is light, and the noise is relatively small. The diesel engine is relatively large, the power is strong, the economic performance is good, and the noise The sound is relatively loud.

According to the fuels used, there 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.

●Classified by valve mechanism type: side valve (SV) engine, side camshaft (OHV) engine, overhead camshaft (OHC) engine, variable gas (VTEC) engine and Desmo valve mechanism engine. ● Classified according to the fuel supply method: carburetor engine, electric injection engine, direct injection engine.

According to the fuel used, it can be divided into gasoline engines, diesel engines, liquefied petroleum gas engines and dual-fuel engines. Classify according to the number and arrangement of cylinders.According to the number of cylinders, it can be divided into single-cylinder engines and multi-cylinder engines.

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

What are the types of car engines?

The types of automobile engines can be divided into naturally aspirated and turbocharged according to the working mode of the air 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 the journey, it can be divided into four-stroke internal combustion engine and two-stroke internal combustion engine.The itinerary mentioned here is the completion of the internal combustion engine.. According to the cooling method, it can be divided into water-cooled engine and air-cooled engine.
