Any diesel engine with a turbocharger is referred to as turbodiesel, often spelled turbodiesel or turbo diesel. Like turbocharging other engine types, turbocharging a diesel engine may considerably improve its efficiency and millage.
The air entering a turbocharged diesel engine is compressed before fuel is injected, significantly changing from a standard gasoline engine.
Here, the turbocharger is crucial for the performance and efficiency of the diesel engine. The job of the turbocharger is to compress more air that flows into the engine cylinder. When air is compressed, the oxygen molecules stick closer together. It can increase the air pressure and you can save your fuel consumption cost.
How does a turbocharger work?
Now let us look, how it actually works. A turbocharger consists of two main parts:
- The turbine
- The compressor
The turbine consists of the turbine wheel and the turbine housing. The function of the turbine housing is to guide the exhaust gases into the turbine wheel. The energy of the exhaust gases rotates the turbine wheel and the gas exits from the turbine housing through an exhaust gas outlet area.
The compressor works in the opposite direction to that of the turbine. The compressor wheel is connected to the turbine by a forged steel shaft and, as the turbine rotates the compressor wheel, the high-speed rotation draws in air and compresses it. The compressor housing then converts high-speed, low-pressure airflow into high-pressure, low-speed airflow through a process called diffusion. This is how diesel turbo work.
What are the advantages of turbochargers in diesel engines?
Diesel Turbo offers several benefits, including:
- Fuel Efficiency: Diesel is more fuel-efficient than gasoline, and Diesel Turbo further increases diesel fuel efficiency. It can save your fuel consumption cost to a great extend and you can use such diesel turbo in your heavy vehicles too.
- Enhanced Performance: Increasing power reduces emissions and improves altitude compensation. Turbocharging an engine increases power output for a given engine weight.
- Higher Torque Output: Additional air entering the cylinder increases air density and pressure, so more fuel is injected, generating more torque, leading to more power. Low-speed torque is also improved.
- Better Towing Loads: The engine has higher towing loads than conventional gasoline and diesel engines. This makes a turbo engine the best choice for agricultural machinery and vehicles that handle heavy loads and must be used off-road.
- Eco friendly: Greener: Turbocharging enables automakers to downsize the engine while delivering power and performance. Smaller engines emit fewer greenhouse gases.
How does the turbocharger work in practice?
For the most part, a diesel turbo consists of two small fans that sit on the same metal shaft so that both fans rotate together. One of these fans is the turbine, located in the exhaust gas flow from the cylinders. You can find two sections in a turbocharger, such as a turbine and a compressor. But, both these parts have several micro parts. For example, a turbine consists of the turbine wheel and turbine housing, and you can find these same parts in a compressor too. The compressor can convert the energy of your diesel engine, and it can convert the high-velocity energy to low-velocity and vice-versa. Every turbocharger consist a turbine wheel, turbine housing, exhaust gas outlet area, compressor wheels, compressor housing, forged sheet shaft and compressed air converter.
Conclusion:
A diesel turbo is a beneficial device used to increase the volumetric efficiency and fuel efficiency of an engine. It uses the energy from the exhaust gases emitted by the engine and uses it to supply compressed air to the engine.
