Typically, engine discharges such as those from internal combustion engines in cars, motorcycles, and industrial machinery, utilize check valves. These valves are crucial for directing the flow of exhaust gases out of the engine and preventing backflow, which could lead to engine damage or inefficient operation. Check valves operate automatically, opening to allow exhaust gases to escape when pressure from the engine's combustion process builds and closing to prevent backflow once the pressure subsides. Their reliability and simplicity make them ideal for managing the high-temperature, high-pressure gases produced by engines. Additionally, in more complex systems, exhaust gas recirculation (EGR) valves are used to reduce NOx emissions by recirculating a portion of an engine's exhaust gas back to the engine cylinders, ensuring cleaner and more efficient combustion.
Butterfly valve is typically used on engine discharges.
An engine stalling at idle can be attributed to several factors, commonly including issues with the air-fuel mixture, spark, or air flow. Dirty or malfunctioning idle air control valves (IAC), clogged fuel injectors, or faulty spark plugs can disrupt the engine's ability to maintain idle by either starving the engine of necessary air/fuel or failing to properly ignite the air-fuel mix. Additionally, vacuum leaks can upset the air-fuel ratio by allowing extra, unmetered air into the engine, leading to a lean condition and stalling. Regular maintenance, such as cleaning the IAC valve, replacing spark plugs, and ensuring the fuel system operates efficiently, can prevent stalling at idle. It's also worthwhile to inspect for vacuum leaks and address them promptly to ensure smooth engine operation.
Engine braking is not entirely prohibited, but it's restricted in some areas due to the loud noise it creates. The mechanism of engine braking in large vehicles like semi-trucks involves opening exhaust valves in the cylinders after the compression cycle, which releases compressed air straight out of the vehicle. This process creates a loud noise similar to the sound of a gun.
Many residential areas, public spaces, or towns have local noise ordinance laws to maintain peace and quiet, and thus prohibit engine braking. It is worth noting that it's not the act of engine braking itself that's banned, but rather the noise it produces.
Engine braking isn't generally an issue for smaller vehicles, because their mechanisms are different and do not create the same levels of noise. Moreover, engine braking can be a beneficial driving technique as it helps control the speed of the vehicle when going downhill and reduces wear on brakes.
