Background technique
EP 1 405 995 B1 disclose a kind of engine system, this engine system comprises explosive motor, have the turbine in the outlet pipe that is arranged on explosive motor and be arranged on the compressor in the suction tude exhaust turbine supercharger, have the exhaust gas recirculatioon pipe that is arranged on the inlet in the outlet pipe in the turbine upstream and is arranged on the outlet in the suction tude in the compressor downstream, and be arranged on the exhaust gas treatment device of the close-coupled (close-coupled) in the exhaust gas recirculatioon pipe.Prove in practice: by means of having inlet that is arranged on closely-coupled exhaust gas treatment device upstream in the exhaust gas recirculatioon pipe and the bypass tube that is arranged on the inlet in turbine downstream in the outlet pipe, described engine system can be worked constantly with extremely low exhaust emissions and optimum NVH performance.
DE 102 59 702 A1 relate to a kind of vent systems that is used for heat engine.This heat engine comprises outlet pipe, in this outlet pipe exhaust heat exchanger is set so that all blast airs are crossed this heat exchanger.In addition, the recirculation that provides the EGR pipe to be used for the part exhaust, the EGR pipe is connected to the downstream side of heat exchanger with respect to exhaust.
The report 2003-01-0629 of SAE (SAE) discloses a kind of explosive motor, this explosive motor comprises the EGR pipe with threeway position control valve, the EGR pipe in the turbine upstream of turbosupercharger from this valve branch and depend on that the operation point is communicated to (opens out in) suction tude in the upstream or the downstream of compressor.The report 2006-01-0047 of SAE discloses a kind of explosive motor of the EGR of having pipe similarly.This EGR pipe is communicated to suction tude in the turbine upstream from outlet pipe branch and in the compressor downstream.In this EGR pipe, be provided with on the cooler for recycled exhaust gas and the flow direction and the EGR valve be set in the downstream of this cooler for recycled exhaust gas in exhaust gas recirculation.The report 2007-04-0034 of SAE relates to a kind of heat exchanger, and this heat exchanger transmits heat to freezing mixture from exhaust.
Turbo charged explosive motor has higher delivery temperature, and this makes needs fuel enrichment so that the material of protection exhaust line (exhaust strand) and the material of turbocharger housing are avoided fire damage under the high load of explosive motor and high-engine rotating speed.In order to address the above problem, developed the highest level (about 870 ℃ of turbine upstream) that exhaust gas recirculatioon (EGR) system is reduced to delivery temperature diesel engine.In order to reduce delivery temperature, will be relatively at high proportion the exhaust gas recirculatioon of (high to 25%) in explosive motor.Yet the exhaust of recirculation was cooled off by cooler for recycled exhaust gas before entering suction tude.Simultaneously, heat exchanger (exhaust heat exchanger) is set in outlet pipe, the heat exchanger expection can be quickened the warming-up process of explosive motor, and this is owing to two reasons as example:
At first, expection reduces CO
2Discharging.By means of heat is delivered to the freezing mixture from exhaust, thereby by means of the oil of heated engine as a result as the heat that absorbs the freezing mixture dissipation, even after cold starting, also can obtain the viscosity of reduction owing to the rapidly pre-warming of engine oil relatively apace, so that frictional force levels reduces.
Secondly, owing to exhaust gas heat is offered corresponding cabin heating system, can advantageously after the cold starting of explosive motor, realize vehicle cabin heat supply faster by freezing mixture.
As mentioned above, need cooler for recycled exhaust gas to be used to cool off exhaust gas recirculation.Regulate the ratio of exhaust gas recirculation by the modulating valve (EGR valve) that on the flow direction of exhaust gas recirculation, is arranged on cooler for recycled exhaust gas upstream or downstream.
High pressure gas recirculating system and low pressure exhaust recirculating system all are known.
