What Pressure Does Turbocharging Increase?
2 Answers
Turbocharging refers to increasing the intake air pressure. Below is an introduction to turbocharging knowledge: 1. Concept of turbocharger: A centrifugal compressor and turbine are combined into one unit, called a turbocharger. 2. Difference between turbocharging and gas turbine: The main difference from a gas turbine is that this unit does not have a combustion chamber and corresponding systems. The turbine operates using the exhaust energy from reciprocating internal combustion engines, and its centrifugal compressor provides compressed air as the charge for reciprocating internal combustion engines. In a turbocharger, the compressor impeller and turbine are assembled on the same rotating shaft, called the rotor. Also mounted on the same rotor shaft and rotating together are sealing components and thrust bearings, among others.
Turbocharging refers to increasing the intake pressure of the engine, which is the pressure of air being forced into the engine before combustion. When driving my small turbocharged car, I can clearly feel the power boost, especially during high-speed acceleration—that surge comes from the compressed intake pressure. Simply put, when the engine exhausts, the pressure of the exhaust gases drives a turbine, which then compresses the incoming air, making the air denser and allowing more fuel to burn, thereby generating greater horsepower. The advantage of this design is that it allows small-displacement engines to deliver high power while being more fuel-efficient for daily city commuting, unlike larger-displacement cars that consume more fuel. Of course, the downside is occasional turbo lag—a slight delay in response when you floor the accelerator—which can be mitigated by improving turbo design or adding an intercooler. Overall, turbocharging has become a standard feature in modern cars, effectively enhancing efficiency and performance, making driving more exhilarating and eco-friendly.
