Intake and exhaust
Intake- and exhaust systems are the breathing of an angine. The more cold air is going through the engine, the more fuel can be injected and the more power can be squeezed. To get more air info cylinder, turbochargers are often used.
But first, the air needs to be cleaned and therefore tractors have big air filters combined with ejector and cyclone systems. Due to extremely dusty conditions when working on the field, the filters may need maintenance daily. As we are talking about tractors nowadays, we can say that they have vacuum sensor on the intake pipe to indicate when it is necessary to clean or change the air filter.
The turbocharger is a turbo-compressor driven by exhaust gas. As said, it has turbine side and compressor side. Exhaust gases escaping the engine are forcing the turbine to turn. The compressor gets drive from the shaft coming from turbine side and pushes cleaned air to the cylinders. Then the air is going to air cooler which can be air-to-air or air-to-water type. The need for intake air cooling comes from the principle that if you compress gas (air in this case), then it will get warmer. The cooler the air is, the more kilos of air can go into engine.
Exhaust gas coming from engine cylinder head is collected by exhaust manifold and directed through turbocharger turbine side to exhaust pipe.
