What pressure does turbocharging increase?

Turbocharging is a technology that utilizes the operation of an internal combustion engine to generate exhaust gases that drive a compressor. Here is more information about turbocharging: 1. In daily life, when people talk about turbocharging, they are mostly referring to the supercharging technology of automobile engines. Essentially, it uses the exhaust gas flow from the engine to drive the turbine inside the turbocharger, which in turn drives the coaxial impeller. The impeller then pushes and pressurizes the air filtered by the air cleaner. 2. When the vehicle's engine and operating speed increase, the speed of the turbine also increases in sync with the engine's speed. Similarly, the impeller compresses more air, forcing it into the turbine. The more compressed air inside the turbine, the more mixed gas enters the vehicle's cylinders. With more thorough combustion of the fuel, the engine's speed increases, thereby enhancing the engine's performance.
Turbocharging primarily increases the air intake pressure when the engine inhales, utilizing exhaust gases to drive the turbine rotation, which in turn powers the compressor to compress air and forcibly inject it into the cylinders. With higher pressure, the engine can intake more oxygen, and when combined with the right amount of fuel, it delivers stronger explosive power, significantly boosting the car's horsepower and providing a strong push-back sensation during acceleration. I often work on these systems and have found that while they enhance performance, attention must be paid to oil lubrication and cooling. Prolonged high-speed driving can lead to overheating and damage to the turbine blades, making regular maintenance crucial.
From a driving experience perspective, turbocharging increases the air pressure before it enters the engine. The engine requires a large amount of air during combustion, and the turbo squeezes it in at a higher density, allowing more oxygen to be packed in. This enables more fuel to be injected, generating stronger power. After adding a turbo to my family car, the acceleration is noticeably faster than naturally aspirated engines, especially when climbing hills in mountainous areas without much effort. However, higher pressure means dealing with heat issues, and aging oil coolers can cause delays. It's recommended not to stomp on the accelerator immediately after a cold start.
Turbocharging increases the pressure in the intake system. It allows the engine to inhale compressed air, optimizing the combustion process, so that small-displacement engines can also deliver high horsepower, being both fuel-efficient and eco-friendly. I've driven many cars, and those with turbos typically consume 20% less fuel with reduced nitrogen oxide emissions, making them very suitable for urban commuting. However, high pressure may cause air leaks in the intake pipes, so it's necessary to check the sealing rings from time to time.
