Diesel Engine Egr System Diagram

This increases fuel economy by ensuring that all of the diesel fuel has been consumed.

Diesel engine egr system diagram.

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. 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. Exhaust gas recirculation egr is the most common technology to reduce nitrogen oxides no x emissions on diesel internal combustion engines ice. Soot buildup due to exhaust gas re circulation egr in turbo diesel engines is a big problem.

Hybrid combined dual loop egr. In internal combustion engines exhaust gas recirculation egr is a nitrogen oxide no x emissions reduction technique used in petrol gasoline and diesel engines egr works by recirculating a portion of an engine s exhaust gas back to the engine cylinders this dilutes the o 2 in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce. Page 9 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. 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.

Not only does it reduce engine efficiency but also reduces po. This type of egr architecture is also called dual loop egr system. Egr takes exhaust gases from the exhaust manifold and reintroduces them into the intake manifold mixing them with fresh air. Duramax diesel engines are installed on many of general motors light and medium capacity pickup trucks.

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.
