4, engine components
valve, Valve, is an important component of the engine. The valve function is responsible for the input air into the engine and exhaust gas after combustion.
From the structure of the engine, into intake valve (inlet vAlve) and an exhaust valve (exhaust valve). The intake valve action is air drawn into the engine, the fuel is mixed with combustion; exhaust valves effect the exhaust gas after combustion is discharged and heat dissipation.
valve material is usually divided into 40Cr, 4Cr9Si2,4Cr10Si2Mo, 21-4N and 23-8N total of five kinds in mainland China. 5Cr8Si2,4Cr9Si3,21-2N, 21-12N, 23-8N, XB, have been used in large quantities in a number of imported models. High temperature nickel-based alloy began to apply a high load on the engine exhaust.
Category from the finished valve structure, usually divided into the whole root valve, the valve and the hollow double metal welding charge valve sodium and the like.
Additional process is typically a top lug, a top surfacing, tapered welding, surface nitriding, chrome surface treatment.
5, valve – valve car
Function valves are dedicated input fuel into the engine and exhaust emissions, the conventional engine has only one intake valve per cylinder and one exhaust valve, which kinds of design structure is relatively simple, low cost, easy maintenance, good low speed performance, power drawback is difficult to improve, especially at high speed, low charging efficiency, performance is weak. In order to increase intake and exhaust efficiency, and now use more multi-valve technology, it is common for each cylinder four valves are disposed (there are three or five cylinder valve designs, the same principles, such as the Audi A6 engine), a total of four cylinders that is, 16-valve, we often see the information on the car’s “16V” says 16-valve engine. Such multi-valve structure can be easily formed in a compact combustion chamber, fuel injector arranged in the center, which can make the combustion air mixture more rapid and more uniform, and the weight reduction of the opening degree of each valve properly, the valve opening or closing faster.
