Why Do Engines Need Backpressure?

In truth, engines don’t really need back pressure. This is one example of a common misconception among those who are not that familiar or not an expert when it comes to automobile matters. Well, back pressure in fact is the one that maintains and regulates the release of the car’s exhaust into a slower stream. This is the one whichenables the temperature of the exhaust valve in order for it to function well and consistently not to mention the fact that it eventually makes the life of the engine live longer and do its purpose better.

If you are not yet convinced, let us try to go further and once again ask this confusing statement about engines and backpressures: “an engine should have a backpressure in order for it to work and function correctly.” Is this true? In the strictest sense, the answer is a big no. It would be categorically more acceptable to assert: “Awell-functioning stock engine which cannot adjust its fuel delivery requires backpressure so as to function work properly.”

Indeed, this idea is but a proven myth. As with all the myths, however, it is always a given fact that there could also be a hint of truth with this statement. Most people especially those who work in vulcanizing shops who did not undergo formal education, considers backpressure the same as torque, and most automobile owners are worried that a small amount of this backpressure mightactually causes the valve to burn.

Basically, the possible reason in which the exhaust valves may burn is due to the fact that the engine is in fact burning lean. Every ordinary car engine can manage lean burning for a just a bit, however, it may not be able to tolerate for a prolonged period of time. This system of car engines brings us to the reality that every engine does not need a back pressure.
