Diesel Engine Egr System Diagram

Egr takes exhaust gases from the exhaust manifold and reintroduces them into the intake manifold mixing them with fresh air.

Diesel engine egr system diagram. The engines are all equipped with an egr valve system which operates by recycling a portion of the exhaust through the engine. Hybrid combined egr system integrates both high pressure egr and low pressure egr on the same engine. 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. Soot buildup due to exhaust gas re circulation egr in turbo diesel engines is a big problem.

This type of egr architecture is also called dual loop egr system. 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. Deposit accumulation contaminants engine lubricant system packaging and more.

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. 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.

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.
