What is Turbocharger

Turbocharging refers to a technology that drives and compresses air through a turbocharger to increase the intake air volume of the engine, so that the fuel is fully burned, thereby obtaining greater torque and power, and improving engine horsepower.

Classification of turbocharging systems

The turbo system is divided into a single turbo system and a twin turbo system.

Single turbo

The supercharging system with only one turbo is a single turbo system. In addition to the turbocharger, the turbocharging system also includes an intake bypass valve, an exhaust bypass valve and an exhaust bypass valve control device.

Twin turbo

The twin-turbo system of the six-cylinder petrol-injected engine. Among them, two turbochargers are arranged in parallel in the exhaust pipe. According to the working order of the cylinders, cylinders 1, 2, and 3 are used as one group, and cylinders 4, 5, and 6 are used as another group. The exhaust of three cylinders in each group is driven a turbocharger. Because the exhaust intervals of the three cylinders are equal, the supercharger turns smoothly. In addition, grouping the three cylinders into groups prevents exhaust interference between the cylinders. In addition to the turbocharger, intake bypass valve, exhaust bypass valve and exhaust bypass valve control device, the system also includes intercooler, resonance chamber and boost pressure sensor.
