SINOTRUK HOWO truck Engine Cylinder Block AZ1246010049​ Now most of the cars, motorcycles and other internal combustion engines are used, the internal combustion engine is a heat engine, which is characterized by the liquid or gas fuel combustion within the machine to generate heat, and then converted to mechanical energy available to the car, a car forward momentum . Take our common car engine, it is a four-stroke reciprocating piston engine. Here are a few concepts need to explain to everyone: first, "Pistons," we should not be difficult to understand, have seen the pump? Pump is to rely on it to work, in fact, the working principle of the engine piston and pump The basic principle of the same; say "reciprocating", that is, the meaning of repeated back and forth, the pump is not to rely on the piston back and forth to the basketball or football sports inflatable what; Finally look at the "stroke", as long as we used the pump to know that the piston From this end to the other end, that is, the piston's entire path of movement, the piston finished the trip path, also completed a stroke (also can be said to complete a trip), although the engine is not used to cheer, but the piston Exercise is about the same, except that the engine needs to complete two more work cycles than the pump. If you are not clear about these concepts at the moment, let's take a petrol engine as an example to explain to you the most basic working principle of the engine. After we understand its working principle, we will understand. First of all, we should know that the engine is to provide power to the car, then what is its source of power? Is the fuel, the most common than gasoline, diesel, now the world is facing the energy crisis and environmental needs, other fuels such as Natural gas, methane, alcohol, hydrogen, etc. also have as a source of power. Common sense tells us that if the fuel is naturally burned in the air, it emits far less energy to drive a car, in order to solve this problem, we need to atomize the fuel, and then compressed to make it under high pressure Burning, so that you can get instantaneous high power, thus driving the car. In order to understand this process, we simply divided the process of the engine into four phases, corresponding to four strokes (intake, compression, work, exhaust). The first stage is "intake": in order to facilitate combustion, gasoline first needs to be atomized outside the cylinder and mixed with the air (we call this mixed gas "mixture"). When the intake valve is open, As the piston moves downward from the top of the cylinder, the pressure in the cylinder becomes smaller and smaller, and the mixture enters the cylinder under the pressure difference between inside and outside. When the piston moves to the lowermost end, the intake stroke ends, Intake valve closed. The second stage is "compression": when the intake valve is closed, the piston begins to move upward, compressing the mixture in the cylinder to prepare for subsequent combustion and ending the compression stroke as the piston moves to the top of the cylinder. In this process, the intake and exhaust valves are closed. The third stage is "doing work": when the piston moves to the top of the cylinder, the mixture has become a high-pressure, high-temperature gas, at which point the ignition (spark plug) ignites them and the mixture begins to burn violently , It burst out of the powerful energy will push the piston down to provide power for the car. In this process, the intake and exhaust valves are closed. The fourth stage is "Exhaust": when the burning gas pushes the piston to the bottom, it releases no energy and the exhaust valve opens and the piston begins to move up again. After combustion Of the exhaust gas is discharged from the cylinder. When the piston reaches the top of the cylinder, the exhaust gas is almost discharged. At this time, the exhaust valve is closed, so that one working cycle is completed. At the same time, the intake valve opens and the piston moves downwards to begin a new working cycle. First to understand the body group. The role of the body as the engine of various agencies, the assembly of the system substrate, and itself is crankshaft connecting rod mechanism, with gas institutions, supply systems, cooling systems and lubrication systems and other components. The cylinder head and cylinder block inner wall together form a part of the combustion chamber, is to withstand high temperature, high pressure parts. Engine body group generally includes the cylinder head, cylinder block and oil pan. We all know that the human respiratory tract is used to inhale and exhaust, and the engine's valve train also has similar functions. Its role is to make the combustible mixture into the cylinder in time and exhaust gas from the cylinder in time. Valve body mainly includes intake valve, exhaust valve, tappet, spring, rocker arm, camshaft and convex
