butterfly valve, first of all, It is defined as a rotating plate mounted on an axis. Its main function is to control the amount of air that flows through it., and this is achieved by positioning it at a certain angle.
In engine applications, The engine throttle valve is usually strategically located in the intake system, specifically between the air filter and the manifold. What makes this valve even more impressive is its ability to be electronically controlled.. The management of the opening and closing of the valve is under the domain of the Electronic Control Unit (ECU), which receives crucial information from various sensors distributed throughout the engine.
These sensors, strategically located at different points of the engine, perform measurements of various parameters that directly influence the combustion process, such as temperature or humidity. At ECU, taking into account this valuable information, emits precise signals that adjust the position of the engine throttle valve optimally.
In summary, The throttle valve is an essential part of the engine intake system., and its ability to be electronically controlled through sensor feedback guarantees efficient and adaptive performance in the combustion process., which contributes to the optimization of the engine in various operating conditions.
Diesel engines are also equipped with a throttle valve but, in this case, It is a regulation valve whose function is to control the recirculation of exhaust gases. Thus, will reduce excess pressure in the intake duct.
The intake throttle valve is located in front of the intake manifold., and it is an essential part for the renewal of the particle filter.
Types of butterfly valves:
- Mechanically Actuated Butterfly Valve: They are activated by pressing the accelerator pedal, because they are tied to it through a mechanical cable. This type of butterfly valve is currently obsolete..
- Electronic Actuated Butterfly Valve: They are activated through a digital signal. They allow greater control of engine power and are much more precise. Consequently, Its operation is more efficient with a lower level of emissions. Currently, It is the most used type of butterfly valve.
