Diesel Engine Egr System Diagram

Series 60 egr technician s manual introduction the series 60 egr technician s guide is intended to be used by a qualified service technician familiar with detroit diesel electronically controlled ddec diesel engines and to provide a better understanding of the egr system to improve the diagnosing of a series 60 egr system.

Diesel engine egr system diagram.

Soot buildup due to exhaust gas re circulation egr in turbo diesel engines is a big problem. Egr systems have been commercialized as a nox reduction method for a wide range of diesel engines from light medium and heavy duty diesel engines right up to two stroke low speed marine engines a number of considerations must be taken into account when designing egr systems including. Duramax diesel engines are installed on many of general motors light and medium capacity pickup trucks. Hybrid combined dual loop egr.

Deposit accumulation contaminants engine lubricant system packaging and more. The advantage of this architecture is that combines the benefit of both low and high pressure egr systems switching between them depending on the operating point of the engine speed and. This increases fuel economy by ensuring that all of the diesel fuel has been consumed.

Exhaust gas recirculation egr is the most common technology to reduce nitrogen oxides no x emissions on diesel internal combustion engines ice. Not only does it reduce engine efficiency but also reduces po. Egr takes exhaust gases from the exhaust manifold and reintroduces them into the intake manifold mixing them with fresh air. Exhaust gas recirculation egr is a system that takes exhaust gas from a diesel s exhaust manifold and reintroduces it into the intake of the engine to reduce the combustion chamber temperature.

The engines are all equipped with an egr valve system which operates by recycling a portion of the exhaust through the engine.
