What does the production process of automobile engines include?

Each part of the engine is separated by its own assembly line, and x0dx0a is then summarized in the assembly workshop of the engine for assembly testing.

In the automobile production process, the four processes of automobile manufacturing are the most critical &mdash&mdash, namely stamping, welding, painting and final assembly. Let's take a look at the content of the automobile production process with the car series of this site.What does the automobile production process include&mdash&mdash introduction Stamping: the production of more than 70% of the body parts.

The whole production line includes the engine assembly line and the cylinder head assembly line, including logistics system, pallet fixture, logistics trolley, tightening machine, marking machine, inspection machine, pressing machine, flipping machine, suspension crane, steel structure, lighting fan system and other equipment and tools.

The working processes of automobile engines are the following 4. The first air intake, the second compression, the third and fourth work, and the fourth exhaust, four processes.

The whole process of the automobile engine assembly line is as follows: the bottom of the cylinder block is facing down, the cylinder block, crankshaft, camshaft feeding, cleaning, blowing, diesel engine model, marking printing. After the cylinder block is flipped 180°, type the number to confirm. After the cylinder is turned over, the bottom of the cylinder is facing up.

The valves are arranged in a row to make the gas distribution mechanism simple, but the spark plug is placed high in the wedge-shaped combustion chamber, and the flame propagation distance is longer. The Cherokee car engine adopts this form of combustion chamber. ( 3) Basin-shaped combustion chamber Basin-shaped combustion chamber, the cylinder head has good technology and low manufacturing cost, but because the valve diameter is easily restricted, the inlet and exhaust effect is worse than that of the hemispherical combustion chamber.

specific workflow of the engine

Before starting, first turn on the ignition switch to the energized position, start the gasoline pump to provide pressure to the fuel supply system, the primary winding of the ignition coil is energized, 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.

The working process of the engine includes four basic stages: air 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.

Engine start-up process I: When the key is turned to the ON position, the ECU is energized when we turn the car key to the ON position. After the ECU is energized, the corresponding sensor is powered on through each pin and the sensor information is obtained to facilitate the control of engine operation. At the same time, the gasoline pump in the fuel tank is energized for 3-5 seconds to provide sufficient pressure on the oil supply system.

The working volume of the cylinder refers to the gas volume swept by the piston from the upper stop to the lower stop, also known as the single cylinder displacement, which depends on the cylinder diameter and piston stroke.Engine displacement is a very important engine parameter. It can represent the size of the engine more than the cylinder diameter and the number of cylinders. Many indicators of the engine are closely related to the exhaust volume.

What is the correct process to start the engine?

Steps to start the car correctly: 1. After getting on the car, adjust the seat to suit you, and then fasten your seat belt. Start the car, then step on the clutch with your left foot and put it in first gear. Turn on the left turn signal and signal with the horn.

After starting, the gear is put in D gear, slowly release the brake, and the vehicle will move forward. If it is a manual transmission, you need to step on the clutch and start the engine, then hang it into 1st gear, slowly release the clutch, move the right foot from the brake pedal to the accelerator pedal, and refuel slightly.The throttle and clutch are used together, and the vehicle moves forward slowly.

The process of starting the engine can be briefly summarized into four steps: air intake, compression, ignition and exhaust. First, the engine is started by a battery or starter, and the air is sucked in from the air filter. At the same time, gasoline is transported from the gasoline pump to the fuel tank to form a fuel-air mixture for air intake.

Automotive Engine Production Process

Each part of the engine is completed separately by its own assembly line, and x0dx0a is then summarized in the engine assembly workshop for assembly testing.

Parts preparation and accompanying process parts, unpacking, cleaning, delivery assembly line. The process of assembly of engine parts. Cylinder head: press-install the valve oil seal → install the inlet door → install the valve lock clip → install the rocker arm assembly → install the inlet manifold → send the general assembly.

The production process of automobiles is a very complex and huge industrial production, but to put it simply, it is: stamping--welding-painting--general assembly. The painted body is assembled in the interior department, such as instruments, glass, chairs, lines, etc.The chassis department installs the engine, transmission, drive axle, tires, etc. on the chassis.

In general, at present, the engine is composed of two major mechanisms and five major systems. The crank connecting rod mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion. It is composed of a fusele group, a piston connecting rod group and a crankshaft flywheel group.

Step 1 The whole process of the automobile engine assembly line is as follows: the bottom of the cylinder block is facing down, the cylinder block, crankshaft, camshaft feeding, cleaning, blowing, diesel engine model, marking printing. After the cylinder block is flipped 180°, type the number to confirm. After the cylinder is turned over, the bottom of the cylinder is facing up.
