The exhaust valve is an indispensable auxiliary component in the
pipeline system. It is widely used at the highest point or elbow on
the pipeline or in places with air locks to remove the gas in the
pipe to clear the pipeline and achieve normal operation. From the
appearance, the overall mechanism design is like a throttle valve
with a relatively simple structure, on which a butterfly valve and
vacuum actuator can be seen. Through the suction of engine vacuum,
the valve can be opened and closed. As long as the valve is
installed at the appropriate position in the exhaust pipe system
and the opening and closing timing is used correctly, the engine
can have balanced torque and horsepower performance. The principle
of this system is to set up a variable valve in the exhaust pipe.
When the rotational speed is low, the valve will close to allow the
airflow to be discharged from a smaller pipe diameter position or a
single pipe. This maintains the back pressure in the exhaust pipe
and allows low rotational speed. Torque is not lost; at high
speeds, the valve will open, and the exhaust gas will be discharged
directly through a large diameter pipe or double pipeline, allowing
the exhaust gas to have more channels and outlets to vent, thereby
reducing the back pressure in the exhaust pipe, so As a result, the
continuity of horsepower will be more ideal.
