The power of the 1.5-litre turbocharged engine is roughly equivalent to that of the 2.0-litre naturally aspirated engine. Turbocharging technology is a simple and effective means to improve engine power. Turbocharging technology can increase the intake volume of the engine without increasing the engine displacement. When the intake volume increases, the injection volume will also increase accordingly, which can improve the power of the engine.

Turbocharging technology has been used in automobile engines for a long time, but at the beginning of its birth, it was not used in automobile engines, but in aircraft engines. Turbocharging technology can solve the problem of insufficient air intake of aircraft engines at high altitude. Later, turbocharging technology was widely used in automobile engines.

The principle of turbocharging technology is very simple. Turbocharged engines have turbochargers, which are composed of two parts, one is the compression turbine and the other is the exhaust turbine. The exhaust turbine is coaxially connected with the compression turbine, the compression turbine is connected with the engine intake manifold, and the exhaust turbine is connected with the engine exhaust manifold. When the engine reaches a certain speed, the exhaust gas has enough energy to drive the exhaust turbine to rotate, and then the compression turbine will also rotate. When the compression turbine rotates, the air can be compressed and delivered to the engine cylinder, thus increasing the air intake.
