cylinder, 12-cylinder, 16-cylinder, of course, these engines will have L series, V-type and W-type layouts respectively. As we usually see, there are basically in-line three-cylinder engines, in-line four-cylinder engines, in-line six-cylinder engines, v-type six-cylinder engines, v-type eight-cylinder engines, etc.
Automotive engine maintenance knowledge inventory Common engine faults First of all, pay attention to the maintenance of the running-in period, which is the basis for extending the service life of the engine. Be careful of the two common diseases of the engine: 1) Engine wear.
Basic knowledge reserve of automobile engine oil span What is oil pan? The oil pan is located in the lower part of the engine: it can be disassembled and installed, and the crankcase can be sealed as the shell of the oil storage tank.The oil pan shell is mostly stamped by thin steel plate, and the more complex shape is generally cast and molded by cast iron or aluminum alloy.
The exhaust volume of ordinary economy car engines also tends to increase. The two most basic parameters for measuring engine performance indicators are: the number of cylinders and the working volume of the cylinder, the latter is the usual exhaust volume.
At present, the most widely used and numerous automobile engines are water-cooled, four-stroke turbocharged internal combustion engines, among which gasoline engines are used in cars and light passenger cars and trucks, while the engines of large buses and medium and heavy trucks are mostly diesel engines. A small number of cars and light passenger and truck engines also use diesel engines.
Some dry knowledge about automobile generators and batteries. Cars rely on engines to drive generators to generate electricity. Car engines are not only used to drive vehicles, but also power many systems in the car.The engine crankshaft has two ends, one end of which is connected to the flywheel, which needs to be docked with the gearbox to drive the vehicle.
Diesel engine is relatively bulky and large in volume; diesel engine's fuel injection pump and nozzle The manufacturing accuracy requirements are high, so the cost is high; the diesel engine works roughly and the vibration noise is loud;Diesel is not easy to evaporate, and it is difficult to start when the car is cold in winter; diesel engines burn diesel, and the price of diesel is cheap.
The differences between gasoline engines and diesel engines are: different ignition methods of fuel, different combustion methods, and different power control methods. The ignition method of fuel is different. The gasoline engine uses spark plugs to ignite the oil entering the cylinder, while the diesel engine relies on the high temperature generated by the compressed air of the piston to make the diesel burn itself.
The difference between gasoline engines and diesel engines mainly lies in the compression ratio, ignition method, fuel used and use. The compression ratio refers to the ratio of the maximum volume and minimum volume of gas in the cylinder when the piston moves in the cylinder.
The difference between the two lies in the difference in combustion mode, torque, speed, emission, etc. The most important thing is that the combustion mode of gasoline engines and diesel engines is completely different. The gasoline engine is premixed flame transfer combustion, while the diesel engine is mainly diffuse combustion.
1. Brands of diesel engines are Weichai, Yuchai, Shangchai, Xichai, SINOTRUK, etc. Weichai Founded in 1946, Weichai is one of the earliest manufacturers in China to produce diesel engines. At present, it is one of the automobile and equipment manufacturing groups with the strongest comprehensive strength in China.
2. The brands of diesel engines are as follows: 1. Judging from the sales volume and comprehensive ranking, Yuchai has always been the leader of domestic diesel engines. The quality and performance are indeed good, but Yuchai is basically not used for heavy tractors. Huaichai is also good. Now it is rising, ranking second only to Yuchai. Dongfeng Cummins can rank third.
3. Diesel engine brands Weichai, Yuchai, Xichai and Quanchai are good, and these brands are recommended.Weichai Weichai is the largest auto parts enterprise group in China. It is the only national key laboratory of internal combustion engine reliability enterprises in the industry, a modern "national enterprise technology center" and a first-class product experimental center in China.
