ENGINE introduce

The engine assembly, also known as the engine, is a machine that can convert one form of energy into another more useful form of energy, usually converting chemical energy into mechanical energy The electric motor, which converts electrical energy into machine energy, is sometimes applicable to both power generation devices and the entire machine including power devices. For example, gasoline engines, aviation engines, and automotive engines generally obtain kinetic energy through internal combustion of gasoline (diesel), so automotive engines are internal combustion engines. According to the different fuels used, they can be divided into gasoline engines and diesel engines. Gasoline engines and diesel engines have their own characteristics; Gasoline engines have high rotational speed, low quality, low noise, easy starting, and low manufacturing costs; Diesel engines have a high compression ratio, high thermal efficiency, and much better emission and economic performance than gasoline engines. Secondly, according to the piston motion mode, piston type internal combustion engines can be divided into two types: reciprocating piston type and rotary piston type. The former piston moves back and forth in a straight line in the cylinder, while the latter piston rotates in the cylinder. Thirdly, according to the number of cylinders, it can be divided into single cylinder engines and multi cylinder engines. Engines with only one cylinder are called single cylinder engines; An engine with two or more cylinders is called a multi cylinder engine. Modern car engines often use three cylinder, four cylinder, six cylinder, and eight cylinder engines. According to the arrangement of cylinders, they can be divided into single row, double row, and three row engines. The cylinders of a single row engine are arranged in a row, usually vertically, but sometimes they are arranged in a tilted or even horizontal position to reduce height. A double row engine arranges the cylinders in two rows, The angle between two columns)

What does the engine assembly include

The engine assembly includes a cylinder block, flywheel housing, transmission gear compartment, water pump, fan, transmission mechanism, timing gear, intermediate gear, filter, oil pan, oil pump, V-belt, crankshaft, connecting rod, piston, flywheel, etc

cowry introduce

The Great Wall Jiayu MPV, also known as COWRY in English, is the first MPV independently developed by Great Wall. It is positioned as a high-end business vehicle for enterprises, with 5 doors and 7 seats, a length of 4574 mm, a width of 1704 mm, and a height of 1845 mm. The entire vehicle has full and smooth lines, strong visual impact, and the tail wing is integrated with the body and headlights. Its prominent features are: abundant power, advanced technology, innovative interior style, fashionable appearance, spacious driving and comfortable space. The internal space is relatively small compared to commercial MPVs, Compared to the larger space of household MPVs, the moderately sized MPV market in China is precisely a blank spot, while Great Wall Jiayu has a relatively moderate space, filling the gap in this MPV market. Its 2.0-liter displacement gives it an inherent advantage in energy conservation and environmental protection, making it a model of the business MPV market
