What are the categories of Petrol Car engines?

Classification according to the intake system: Internal combustion engines can be divided into naturally aspirated (non-supercharged) Petrol Car engines and forced induction (supercharged) Petrol Car engines according to whether the intake system adopts a supercharged method.

Classification according to the cylinder arrangement: Internal combustion engines can be divided into single-row, double-row and three-row types according to the cylinder arrangement. The cylinders of a single-row Petrol Car engine are arranged in a row, usually vertically, but in order to reduce the height, the cylinders are sometimes arranged tilted or even horizontally. A dual-row engine arranges the cylinders in two rows. The angle between the two rows is <180° (usually 90°). It is called a V-type gasoline engine. If the angle between the two rows = 180°, it is called an opposed engine. Roewe Car engine. Generally, Roewe Car are divided into 6-cylinder and 8-cylinder Petrol Car engines, and are also divided into in-line cylinders and V-row cylinders. The three-row engine arranges the cylinders in three rows to become a W-type Petrol Car engine.
Classification according to the number of cylinders: Internal combustion engines can be divided into single-cylinder Petrol Car engines and multi-cylinder Petrol Car engines according to the number of cylinders. A Petrol Car engine with only one cylinder is called a single-cylinder Petrol Car engine; a Petrol Car engine with more than two cylinders is called a multi-cylinder Petrol Car engine. Such as two-cylinder, three-cylinder, four-cylinder, five-cylinder, six-cylinder, eight-cylinder, 12-cylinder, 16-cylinder, etc. are all multi-cylinder Petrol Car engines. Modern automotive gasoline engines mostly use four-cylinder, six-cylinder, and eight-cylinder gasoline engines.
Classification according to cooling method: Internal combustion engines can be divided into water-cooled Petrol Car engines and air-cooled engines according to different cooling methods. Water-cooled Petrol Car engines use the coolant circulating in the cylinder block and cylinder head cooling jacket as the cooling medium for cooling; while air-cooled engines use the air flowing between the radiators on the outer surface of the cylinder block and cylinder head as a cooling medium. cooling medium for cooling. Water-cooled gasoline engine has uniform cooling, reliable operation and good cooling effect, and is widely used in modern automotive gasoline engines.
Classification according to the fuel used: Internal combustion engines can be divided into gasoline engines and diesel engines according to the different fuels used. An internal combustion engine that uses gasoline as fuel is called a gasoline engine; an internal combustion engine that uses a diesel engine as fuel is called a diesel engine. Gasoline engines and diesel engines have their own characteristics; gasoline engines have high speed, low mass, low noise, easy starting, and low manufacturing costs; diesel engines have large compression ratios, high thermal efficiency, and better economic performance and emission performance than gasoline engines.
