As one of the core components of a car, the importance of the engine naturally goes without saying. The development and manufacturing of the engine is even more of an issue for automotive manufacturers. Therefore, each manufacturer has its own unique engine technology, and these technologies have brought us even better cars.
Lifting a car engine seems to always bring back people's curiosity. What parts of the engine constitute? How was it made? How to assemble it? ... Do you want to learn about the engine story? Then follow Xiaobian together to explore the manufacturing process of the engine!
The engine that we are going to talk about next time is not an assembly line product of an auto manufacturer. It is an amateur amateur work of mechanical enthusiasts. Its exquisiteness is no less than the mass production of the engine. It is enough for us to understand the whole The engine's construction, processing, and assembly process.
Before processing, prepare a large piece of aluminum. Then through the planer, milling machine, it slowly polished, processed into the engine's cylinder.
In order to reduce the processing difficulty, the processor designs the crankshaft to be synchronized, that is, the crankshaft is in the same position during operation. Although reducing the difficulty of processing, but this approach has amplified the power output deficiencies, so that the power output of the blank part is greater, but also not conducive to solve the problem of engine jitter.
This small carburetor requires a lot of effort, not only requires high precision machining, but also takes into account the impact on the intake and intake pressure, or some technical difficulties.
Formed engine block and cylinder liner, placed next to a coin, can be used as a reference, in order to speculate the size of the whole machine. The cylinder liner, on the other hand, has a very high requirement for machining accuracy. This is the basic condition for ensuring the reliability and normal operation of the engine. The piston is the same.
The engine valve, which is the “throat†that controls the “breathing†of the engine, is a diesel engine and a gasoline engine.
The camshaft is used to control the valve operation. The above figure shows the camshaft being processed. It can be seen that several bumps have been machined on the originally smooth iron and the opening and closing of the valve is controlled by them.
Assembled parts are assembled, the engine is basically formed, but the engine can not run at this time, but also need more parts to match.
In order to ensure the smooth operation of the engine, it is necessary to go through some testing procedures when processing components to ensure the accuracy and reliability of the parts.
This exquisite fan blade will be installed behind the cooling water tank and act as a cooling fan. The completely hand-made blade is like a craftwork, and people can't help but want to collect it.
The fully-formed engine still cannot work immediately, and some adjustments need to be made to see whether the phase of the camshaft and the crankshaft piston meets the running angle, whether the valve can seal the cylinder, the carburetor oil intake amount and atomization effect. Whether the cooling system can control the temperature of the engine, etc. This is the time to really test the technology of the makers.
Take a look at how many accessories are needed for a complete engine! After the V4 engine was completely dismantled, its parts covered the entire table. It was not easy to make an engine!
A complete engine must have the following accessories: cylinder, crankshaft, camshaft, piston, piston rod, cylinder, cylinder liner, valve, valve linkage, cylinder head, oil pan, fuel supply, seal ring, Heat sinks, flywheels, etc. Of course, these are just basic configurations of the engine.
If you want the engine to have more power and higher operating efficiency, you must also have these technologies: turbocharged, in-cylinder direct injection, high pressure common rail, valve timing, multi-point EFI, graphite coating, variable cycle , variable compression ratio, lean combustion, stratified combustion, etc. (PS: diesel engine and gasoline engine technologies have all been mentioned). However, these technologies must have sufficient funds to support R&D. Therefore, although the enthusiasts of the engine can produce an exquisite engine, the lack of follow-up equipment technology is still a certain distance away from the normal use of the engine.
Independently designing and manufacturing an engine requires a good understanding of the structure of the engine, as well as superb Cnc Machining capabilities. Parts also require patience. The master who processes this engine must be a veteran industry insider. To see this, do you want to start with one? Oh, endless fun!
3D Printing (3DP) is a kind of Rapid Prototyping technology, which is a kind of technology to construct objects by layer-by-layer printing based on digital model files by using powdery metal or plastic and other adhesive materials.
3D printing is usually realized by digital technology material printer.It is often used in mold manufacturing, industrial design and other fields to make models, and then gradually used in the direct manufacturing of some products. There are already parts printed by this technology.The technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields.
