Soon after this, different types came out in the same category because all manufacturers needed to remember emission guidelines before making any innovations. 6.0L, 6.4L, and 6.7L came one after the other. The 6.7L is the one to keep an eye on today. It has a single turbocharger and is quite lightweight while being extremely strong. It is compatible with B20 Diesel and comes with rocker arms valve operation. It also has an inverse-flow configuration.

Duramax Engine

The latest Duramax Engine is the 6.6L Duramax L5P, which has a great number of exciting features such as Venturi Jet Drain Oil Separator, Exhaust Gas Recirculation System, electronically controlled turbocharger, lower exhaust emissions, 6-speed automatic transmission, and cold-start system when the weather conditions are not favorable.
