Car & Truck Turbo Chargers & Parts

The turbocharger is a motor-driven device that boosts the horsepower of a car or truck engine without adding enormous weight to the vehicle. It is normally found in high-performance race cars and large construction equipment engines or motors and consists of various components.

What are the main parts of a turbocharger?

The main components of a turbo include:

  • Turbine - It propels the entire turbocharger. The exhaust flow turns the wheel in the turbine which then propels the rest of the turbo. It consists of two components: the turbine housing and the wheel.
  • Compressor - This facilitates the burning of more air and fuel. It does this by compacting the air into the cylinders thus creating extra room.
  • Air filter - The air filter is vital in that it protects the automobile from contaminants and harmful particles. The air that is sucked in goes through the filter prior to entering the engine itself. It prevents negative effects due to contaminants.
  • centre hub rotating assembly - This encompasses the shaft that connects the compressor impeller to the wheel. It has a bearing system that suspends the shaft and spins it at great speeds with little to no friction.
  • Wastegate - This is the second passage for surplus air to pass through. A certain amount of exhaust is required so as to have the right pressure amount. Ultimately the car will produce extra output to propel the turbocharger. The wastegate is a valve that discharges excess output to balance the pressure amount in the turbo.
  • Intercooler - This is fitted to cool down the hot air from the turbocharger. It works like a radiator except that it uses air for cooling instead of water. It comes in different sizes and can be top-mounted or front-mounted.
  • Light compressor wheel - This is useful in reducing lag since they are made from a lightweight metal alloy. As they are lighter, they spin easily.
  • Turbo timers - These help keep the engine operational for a specified amount of time after being shut off, allowing all the components to cool down and circulate the oil out of the turbocharger.
How does a turbocharger work?

The turbo incorporates the exhaust flow starting from the engine to turn a turbine. The turbine then spins an air pump. It is responsible for allowing extra air into the car's existing cylinders, increasing the fuel amount the automobile can burn. This increase in fuel burned creates extra power.

What are the benefits of a turbocharger?

  • It is economical on fuel consumption.
  • It makes little noise.
  • Its performance and power generation improves with an increase in altitudes. This is due to the great pressure difference between the air ahead of the turbo and low pressure.
  • It has a smaller size and weight for an automobile producing a certain amount of power. Thus, it is more efficient.
  • Due to the small size of a turbocharged engine, it creates fewer emissions.
