Understanding How Turbos Work in Diesel Engines

When modifying an engine, there are many ways to add additional power or attempt to increase the machine's efficiency. Installing a turbocharger is one of the most beneficial enhancements for a diesel engine. Understanding how turbos work in diesel engines is all about knowing what the turbocharger does and how its actions benefit your machine.

What Does a Turbocharger Do?

Turbochargers work by sucking in the exhaust gas and sending it through a turbine wheel. The turbine wheel spins alongside a compressor wheel that sucks in air and compresses it, making it denser and hotter. As the thick air flows through a cooling system, it becomes even denser before making its way into the engine. This allows the engine to burn more fuel and increase power and efficiency.

Difference Between Diesel and Gas Turbochargers

When it comes to understanding how turbos work in diesel engines, it's a good idea to look at the differences between how turbochargers affect two primary types of machines. While the turbo principle is roughly the same, diesel differs by having a difference in combustion. Diesel requires much more pressure and higher temperatures to combust in the engine, which typically means more RPMs on the compressor wheel and less cooling as it goes into the machine.

Benefits of Turbocharging Diesel

There are several positive effects to running a turbocharger through your diesel engine. Aside from improved horsepower for faster speeds, turbocharging your engine increases fuel efficiency. Diesel is already more fuel-efficient than gasoline, and a properly turbocharged engine offers better mileage and a cleaner burning engine.
