detonator>yilongThe engine
The mechanism that converts internal energy into kinetic energy is called the engine, and the engine is mainly in the form of cylinders and pistons as the internal combustion engine of the converter. Depending on the fuel and the type of ignition, it can be divided into a gasoline engine or diel engine, or an engine with hydrogen, natural gas, and oil and gas as fuel, and its combustion form is less different from that of gasoline engines. According to the work cycle and piston stroke characteristics, it can be divided into two stroke and four stroke engines.
Engine
To be able to translate into kinetic energy of the body known as the engine, car engine is the main form of the cylinder and piston of internal combustion engine as a conversion mechanism. According to the fuel and ignition forms can be divided into different gasoline engine or a diel engine, or hydrogen, natural gas, petroleum gas as fuel to the engine, the gasoline engine combustion form and smaller differences. According to the working cycle and piston stroke characteristics, and can be divided into two stroke and four stroke engine,

The construction and working principle of internal combustion engine
The structure and working principle of internal combustion engine
The working chamber of reciprocating piston type internal combustion engine is called cylinder, and the inner surface of the cylinder is cylindrical. The piston of reciprocating motion in the cylinder is hinged by the piston pin and the connecting rod, and the other end of the connecting rod is connected to the crankshaft, which forms the crank connecting rod mechanism. Therefore, when the
初一英语上册单词表piston is reciprocating in the cylinder, the connecting rod pushes the crankshaft to rotate, or vice versa. At the same time, the volume of the working chamber is constantly changing from the smallest to the largest, then the largest to the smallest, and so on. The top of the cylinder is clod with a cylinder cover. The intake and exhaust doors are mounted on the head of the cylinder head, and the intake and exhaust valve is mounted upside down to the top of the cylinder. Through the opening and closing of the inlet and exhaust doors, the air cylinder can be filled up and out of the cylinder.
The opening and closing of the exhaust door is controlled by camshaft. The camshaft is driven by the crankshaft through the toothed belt or gear or chain. The inlet, exhaust valve and camshaft and other components form the gas distribution mechanism. This structure is usually described as a gas distribution mechanism with a roof valve. The modern internal combustion engine adopts the roof valve distribution mechanism without exception. The parts that make up the cylinder are called the cylinder block, and the part of the supporting crankshaft is called the crankca, and the cylinder body and the crankca are called the body.
Reciprocating piston internal combustion engine working chamber called the cylinder, the inner surface of the cylinder. In the cylinder for reciprocating motion of the piston through the piston pin an长沙出国留学
d one end of the connecting rod is hinged, the other end of the connecting rod is connected with the crankshaft, form the crank connecting bar mechanism. Therefore, when the piston in the cylinder for reciprocating motion, the connecting rod drives the crankshaft to rotate, or the opposite. At the same time, a working chamber volume is also constantly from the smallest to the largest, again by the maximum to minimum, so the cycle. The top end of the cylinder by cylinder lid closure. The cover of the cylinder is provided with the inlet valve and exhaust valve, intake, exhaust valve head down tail up upside down in the cylinder top. Through the inlet, exhaust valve opening and closing to within the cylinder to cylinder exhaust gas and. Inlet, exhaust valve opening and closing is controlled by a camshaft. Cam shaft by the crankshaft via a toothed belt or a gear or chain drive. Inlet, exhaust valve and the cam shaft and other parts compod of gas distribution mechanism. Often
called the structural form of the gas distribution mechanism for overhead valve mechanism. Modern car engines are invariably us overhead valve mechanism. To form the cylinder parts called cylinder body, supporting the crankshaft parts called the crankca, cylinder block and crankca casting body known as the body.
The working principle of
suerThe working principle of a four-stroke gasoline engine
The four-stroke reciprocating piston internal combustion engine completes the four process of intake, compression, work and exhaust during the four piston trips, namely, only one process is carried out in one piston stroke. As a result,
The piston stroke can be named after four process.
1. Air intake stroke
The piston moves from the top to the bottom of the crankshaft. The exhaust valve clos and the intake valve opens. During the movement of the piston, the cylinder volume gradually increas and a certain vacuum degree is formed in the cylinder. The mixture of air and gasoline is inhaled through the intake valve and further mixed into a combustible mixture in the cylinder.
2. The compression stroke
At the end of the intake stroke, the crankshaft continues to
drive the piston from the bottom to the top stop. The inlet and exhaust doors are clod. As the piston moves, the cylinder volume decreas, and the mixture in the cylinder is compresd, and its pressure and temperature ri simultaneously.
3. Work trip
At the end of the compression stroke, the spark plug that is installed on the cylinder head generates an electric spark, which ignite the combustible mixture in the cylinder. The flame quickly travels through the combustion chamber, releasing a lot of heat energy. The volume of combustion gas expands rapidly, and the pressure and temperature ri rapidly. Under the action of the gas pressure, the piston is moved from the top to the bottom, and the crankshaft rotates to work through the connecting rod. The inlet and exhaust doors are still clod.
4. The exhaust stroke
Exhaust stroke, the exhaust valve opens, the inlet valve is still clod, the crankshaft by connecting rod drives the piston by the next check point moves to the first check point, the combustion gas after the expansion at this time (or gas) on residual stress and its own under the impetus of the piston, through the exhaust discharge outside the cylinder. When the piston reaches the upper stop, the exhaust stroke ends and the exhaust gate clos.
