Definitions
- Exhaust gas recirculation assemblies are used in direct injection diesel engines in order to reduce NO x emissions which are particular problem in engines designed to run at high temperature.
- a proportion of the exhaust gas is led from the exhaust system into the body of a heat exchanger through which liquid coolant from the engine is passed in order to cool the exhaust gases which then pass out of the body of the heat exchanger through an outlet connection.
- the cooled exhaust gases pass, possibly via a linking tube, into the inlet connection of a separate flow control valve having an outlet connection which communicates via another tube with the air intake manifold of the engine.
- the flow control valve is controlled by the engine management system to give the required amount of exhaust gas recirculation depending upon the amount of NO x being produced under the prevailing engine conditions.
- the housing comprises a second chamber in which the adjustable flow control valve member is mounted, the second chamber communicating with the first chamber so that the exhaust gas flow passage extends through these chambers.
- Fig. 1 is a part cut-away schematic view of an exhaust gas recirculation system according to one example of the present invention.
- the exhaust gas recirculation system according to the present invention further comprises a flow control valve indicated generally by arrow 40, and an exhaust gas heat exchanger 42, each of which is formed as a separate sub-assembly.
