How to Reduced exhaust air resistance and makes exhaust gas more open?

March 24, 2022

Exhaust Fan more useful in our life. And their's valve mechanism has been widely used in the past nearly one hundred years due to its simple structure, easy construction, and low cost, and can meet the requirements of gas engines for general gasoline engines.

However, in recent years, with the application of electronic control, gasoline injection and turbocharger technology in automotive engines, it is clear that the two-valve mechanism is not sufficient to ensure that the engine has good ventilation quality, so as to give full play to the engine's dynamic performance and economy. The potential, then, multi-valve engine is born and developed in this context.

The so-called multi-valve engine refers to an engine that has more than two valves per cylinder. The current multi-valve mechanism includes three-valve four-valve and five-valve, among which four-valve, that is, two intake valves and two exhaust valves are the most common because the multi-valve mechanism can improve the quality of the engine's ventilation, so that it has Higher power and better fuel economy, so since it first appeared in Japan. It has been widely noted by the automotive community around the world. In addition, the reason why the exhaust valve is clear and how many valves have recently achieved such a good effect is because the increase in the number of valves makes the passage of intake and exhaust gases important. .

Therefore, the application of the multi-valve mechanism is currently limited to medium and high-grade passenger car engines. This is the direction in which the automobile industry has changed its development direction. Can be transmitted to the precise location of the vehicle, so the GPS can be regarded as the key to the vehicle information communication. The GPS technology was originally developed by the US military to guide the nuclear missile to accurately fly to the target. The signals received from one or more satellites are triangulated to determine the precise location of the vehicle.
