There are two ways to make an internal combustion engine more powerful. The first is to increase the engine volume, the second is to increase the fuel supply and the amount of air into the engine cylinders. The consequence of an increase in engine volume is an increase in fuel consumption and engine size (which is not always appropriate). But the forced increase in the amount of air in the engine cylinders does not entail such disadvantages. So, engines equipped with such a device are called turbocharged.

Types of turbocharging

There are three methods of increasing the amount of air. The first is the use of kinetic energy in the intake manifold (resonant method), which does not require a supercharger. The second is that the air is pumped using a compressor, which operates using an engine (mechanical method). The third is the use of exhaust gases for supercharger operation (gas turbine method).

Resonant boost

This method is used in most cases in engines with distributed fuel injection. That is, in engines where each cylinder has its own nozzle "fixed". The computer gives a command and the injectors supply a certain amount of fuel to the collector section, near each of the cylinders.

The task of such a boost is to provide an increased pressure of the fuel mixture (fuel + air), at sufficiently high speeds, namely 3 – 3.5 thousand (revolutions per minute). However, increased blood pressure is not required all the time. It only needs to increase at the moment when the valve closes, and an additional amount of fuel mixture gets there. In words, everything is quite simple and clear, but there is one caveat. The valve opens at different speeds of the crankshaft for different times. In this regard, pipelines of variable length began to be used. This is probably the end of the process of developing such a boost. In parallel with this, there was already a more productive turbocharging.

Mechanical supercharger

This method of supercharging involves the joint operation of the engine crankshaft and supercharger. Namely, the supercharger is powered by the crankshaft. A belt drive is used to connect these devices. The advantage of this method is reliability, and it does not require "high-quality" fuel, as in the example with a gas turbine boost.

Gas turbine boost

Exhaust gases enter the turbine, where their energy helps to unwind the turbine rotor, and only then these gases enter the muffler.

The compressor takes air from the air filter, then the pressure is increased by 30 to 80 percent and further supplied to the engine. It is located on the same shaft as the turbine wheel. The turbine wheel reaches a very high rotation speed of 10,000 (revolutions per minute), and it heats up to 1,000 degrees Celsius. In this regard, special bearings made of high-strength steel are used there. It is not difficult to understand that such a device will require high-quality lubrication.
