The work order of the six-cylinder four-stroke engine is generally

The ignition interval of the four-stroke V-type six-cylinder engine is still 120, and the three cranks are 120 each other. The working order is R1-L3-R3-L2-R3-L1. Facing the cooling fan of the engine, the right cylinder is represented by R, and the cylinder numbers from the front to the rear are RRR3 respectively; the left exhaust cylinder is represented by L, and the cylinder numbers are LL2 and L3 respectively.

The ignition interval of the four-stroke in-line six-cylinder engine is 120°, and the six bends are 120° to each other. The working order is 1-5-3-6-2-4 or 1-4-2-6-3-5.If it is a V-type six-cylinder engine, the interval angle is still 120°, and the three bends form 120°.

The cylinder is 120 degrees after the upper stop point of the intake stroke, and the 6 cylinder is 120 degrees before the stop point on the compression stroke. For a 2-stroke engine, the 3 cylinder is at the compression stop point, the 5 cylinder is working, the 1 cylinder is working, the 4 cylinder is in the air intake, the 2 cylinder is in compression, and the 6 cylinder is in compression.

The ignition order of the in-line six-cylinder engine is: 4 or 5. Each cylinder works in a certain interval and in order to make the engine run continuously and smoothly. At the same time, the six-cylinder engine avoids the continuous fire of two adjacent cylinders, which can reduce the bearing load.

The work order of a four-cylinder four-stroke engine is generally 2 or 3; the work order of a six-cylinder four-stroke engine is generally 4. Knowledge expansionExhibition Four-cylinder four-stroke engine is a common internal combustion engine, which is widely used in automobiles, machinery and equipment and other fields.

The working order of the four-stroke inline engine is 1-3-4-2 or 1-2-4-3. It is customary to use 1 tank as the standard, 1 tank to do the work, followed by 3 tanks to do the work, and so on. The cylinders of the four-stroke in-line engine cycle in the order of 1-3-4-2 and work continuously.

How do the engine working steps work?

1. Working process: air intake-compression-oil injection-combustion-expansion work-exhaust. The working quality that enters the cylinder is pure air. Due to the small resistance of the intake system of the diesel engine, the intake end pressure pa=(0.85~0.95) p0, higher than gasoline engine. The intake end temperature is Ta=300~340K, which is lower than that of a gasoline engine.

2. Before starting, first turn on the ignition switch to the energized position, start the gasoline pump to provide pressure to the fuel supply system, energized the primary winding of the ignition coil, and the engine electronic control system is ready. Then, turn the ignition switch to the starting position, the starter is energized, the engine crankshaft rotates, and the engine works.

3. Engine working process: air intake-compression-fuel injection-combustion-expansion work-exhaust. An engine is a machine that can convert other forms of energy into mechanical energy. It was first born in the United Kingdom. It is suitable for both power generators and the whole machine including power generators. Air intake stroke The quality that enters the cylinder is pure air.

4. During the intake process, the crankshaft rotates, and the piston moves from the upper stop point to the lower stop point. At this time, the intake valve is open. Due to the downward action of the piston, the volume above the piston increases, resulting in vacuum suction. The fuel and air are atomized into a combustible mixture by the carburetor, and are sucked into the cylinder through the intake valve.

Introduction to the working sequence of the automobile engine

The working process of the engine includes four basic stages: intake, compression, combustion (ignition) and exhaust. An engine is an energy conversion device that converts the chemical energy of fuel into thermal energy, and then converts thermal energy into mechanical energy to drive the vehicle.

To move it, you first need to move its external force.The external force is generally provided by the starter. Early engines did not have a starter, and the engine was rotated by shaking the steering wheel, pulling the rope and other forces. Nowadays, cars are generally started by electric starters.

Intake stroke The intake stroke sucks the flammable gas mixed with gasoline and air into the cylinder. After the intake stroke begins, the intake valve opens, the exhaust valve closes, the crankshaft rotates, the piston moves from the upper stop point to the lower stop point, the volume above the piston increases, and the pressure decreases. The combustible mixture of gasoline and air enters the cylinder due to the pressure difference.

Car engines generally use 4-stroke engines. ( Mazda's rotor engine will not be discussed here. The automobile picture newspaper has introduced it) The 4 strokes are: intake, compression, combustion and exhaust. After completing these 4 processes, the engine completes a cycle (2 laps).

What is the working order of the 4-cylinder engine?

1. The working order of the four-cylinder engine is generally 1-3-4-2 or 1-2-4-3. The different crankshaft structure determines that the 4 cylinders are the same as above and the 3 cylinders are the same as above. But there are two processes between the two. There are four processes in the engine. The intake process and the work process are the downward movement of the piston, and the compression process and the exhaust process are the upward movement of the piston.

2. Analysis of the workmanship sequence of the four-cylinder engine: the ignition order of the four-cylinder engine is 1-2-4-3 or 1-3-4-2.

3. There are two kinds of working order of four-cylinder engines: 1-2-4-3 or 1-3-4-2. The working order of four-cylinder engines depends on the structure of the crankshaft and other factors.The working cycle of a four-stroke gasoline engine consists of four piston strokes, namely intake stroke, compression stroke, work stroke and exhaust stroke.

4. Automobile four-cylinder stroke engine, the working order of the four-cylinder engine is 1-2-4-3 or 1-3-4-2. The working order of the four-cylinder engine depends on the crankshaft structure and other factors. The working cycle of a four-stroke gasoline engine consists of four pistonstrokes, namely intake stroke, compressionstroke, workingstroke and exhauststroke.

5. Cylinder arrangement and engine ignition order: When arranging the ignition order of multi-cylinder engines, attention should be paid to keep the two cylinders as far away from each other as possible to reduce the load of the main bearing. Therefore, the work order of 4-cylinder engines is generally 1-3-4-2, or 1-3-2-4.

6. The order in which the engine cylinder is ignited in a working cycle is called the engine ignition sequence. The reasons that affect the ignition order of the four-cylinder engine are as follows: the bend on the crankshaft is the biggest influencing factor. The 1-4 cylinders of the four-cylinder engine are on the same plane as the bend, and 2-3 are on the same plane.
