Classification of exhaust bellows

Views:0     Author:Site Editor     Publish Time: 2021-08-13      Origin:Site

Above we introduced the basic information of the exhaust bellows, and then we introduce several basic types of the exhaust bellows. According to the different styles of the exhaust bellows, the operation mode of the exhaust bellows is also different.

Here is the content list:

Backpressure tube

Halfback pressure exhaust bellow

Straight through exhaust bellow

Semi-through exhaust bellow

Semi-double valve variable exhaust bellow

 

Backpressure tube

It is more environmentally friendly than the original exhaust bellows, and the principle is the same as the original exhaust bellows, but the sound will be better than the original exhaust bellows. Most of the original exhaust bellows use this kind of tube. It is mainly based on the grating muffler in the exhaust bellows tube or the volume change of the tube to generate a pressure that will return to the cylinder. When the exhaust bellows engine is ignited, the exhaust bellows piston starts a radial stroke.And the exhaust bellows exhaust valve will open before the piston reaches the bottom dead center. At this time, the backpressure in the exhaust bellows tube will block the exhaust gas from rushing out, allowing the exhaust bellows mixture to achieve complete combustion. However, if the backpressure of the exhaust bellows is too strong, the exhaust bellows exhaust gas cannot be completely discharged from the cylinder, causing the exhaust bellows exhaust gas and the mixture to burn together to reduce the combustion efficiency. Of course, the most direct thing is to affect the horsepower output of the exhaust bellows. Advantages: the exhaust bellows have low noise and good low-speed torque.

 

Halfback pressure exhaust bellows

This kind of exhaust bellows has lower back pressure force, and the compliance of exhaust is better than that of backpressure pipe. Simply put, it has moderate backpressure between the backpressure pipe and the straight pipe to obtain the starting torque and exhaust compliance. Better than the backpressure tube, of course, the torque of the middle and high speed is also greater than the back pressure tube. Advantages: the torque performance is good at the middle and tail speeds

 

Straight through exhaust bellows

The acceleration will be better than the exhaust bellows of the backpressure pipe. The exhaust bellows have extremely low back pressure, no resistance to exhaust bellows, poor low-speed torque, and high-speed torque. Advantages: The exhaust bellows have smooth exhaust and strong high-speed torque.

 

Semi-through exhaust bellow

The semi-through exhaust bellows are the same as the semi-return pressure exhaust bellows, but the exhaust diameter is larger than that of the half-return pressure exhaust bellows. Advantages: the starting torque is lower than the half-return pressure, but the mid-to-high speed torque is larger.

 

Semi-double valve variable exhaust bellow

A variable exhaust system is connected to the exhaust bellow pipe, and a side pipe is added to the exhaust bellow. When one exhaust bellow pipe is fully opened, the other exhaust bellow pipe is completely closed. Compared with the single-valve variable exhaust bellow, the exhaust bellow has a better sound effect, and the opening degree of the exhaust bellow is 1/3 At that time, the sound effect of exhaust bellow was more single-valve exhaust the same. The sound can be switched on and off, and the exhaust can change the size of the sound.

Variable exhaust bellow The exhaust bellow is controlled by a valve to achieve the best sound and performance.
