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)
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
The Dongfeng Xiaokang K07S is superior to its peers in terms of space, power, and load-bearing capacity, making it one of the best new economy micro passenger models. In terms of appearance, the Dongfeng Xiaokang K07S adopts a brand new family style design, with two simple front air grilles and round and full front headlights complementing each other, making it more approachable and recognizable. Its door design adopts a combination of driver and passenger double doors and side sliding doors, It also facilitates passengers to board the car from the middle row, and to some extent improves its aesthetics. The Dongfeng Xiaokang K07S is also the most spacious model in its class, with body dimensions of 4070mm in length, width, and height, respectively × 1560mm × 1910mm, with clever spatial layout, its maximum cargo capacity can reach 4.14m ³, In addition, the rear seats are detachable, allowing for flexible use for carrying passengers and cargo, making it highly practical
