What should I pay attention to when customizing valve exhaust?

Exhaust gas is the exhaust gas discharged after engine combustion. If you turn off the exhaust gas, you can't get it out. If the air can't get out, new air can't get in. The engine won't explode without air. Lack of motivation is only the initial phenomenon. If the gas is turned off for a long time, it will be turned off. The exhaust pipe can be modified but cannot be closed.

1. Is there any damage to the automobile with modified valve exhaust?

Because the opening and closing of this valve does not match the characteristics of the engine, it is universal, and there will be power lag from the closing stage to the opening stage, unless it is a variable valve that matches the speed and valve technology, the best effect can be obtained. At present, the variable valve popular on Taobao only takes the speed signal and throttle signal as the judgment standard. In daily use, the valve is closed, and the back pressure and exhaust flow are almost the same as those of the original car, which will not damage the low torque.

2. Aerodynamic aircraft:

Pneumatic cars use pneumatic engines to drive cars by converting the pressure energy of high-pressure gas into mechanical energy. Compared with the traditional internal combustion engine, the pneumatic engine has no high-temperature and high-pressure gas combustion process in the cylinder, and only achieves the purpose of outputting power through simple gas expansion, so there is no need for a complex cooling system, and the engine body can also choose low-strength and lightweight materials and a simple structure, so it has simple structure, small volume, light weight and low cost.
