Low Pressure Egr System

Low Pressure Egr System. Further lower emission levels can be achieved by adopting a system that combines lpl egr with a nox storage and reduction (nsr) catalyst. Low pressure loop (lpl) egr systems are effective means of simultaneously reducing the nox emissions and fuel consumption of diesel engines.

Utilising the exhaust gas after the turbocharger enables flexible engine operation and makes it easier to switch engine operation modes between with or without egr system when sailing in. Low pressure egr systems draw low pressure exhaust from downstream of an engine's turbine and direct the exhaust to a location upstream of the engine's compressor. 3rd scheme (low pressure egr used by pumpe duse vag's engine) use throttle at the intake pipe to make intake manifold vacum, and so the exhaust pressure is higher than the intake and part of the exhaust gases can now be sucked back to the intake.

In a low pressure egr system, the exhaust gas is taken after the turbine and reintroduced into the intake manifold before the compressor, thus in the low pressure zone of both exhaust and intake manifolds. 3rd scheme (low pressure egr used by pumpe duse vag's engine) use throttle at the intake pipe to make intake manifold vacum, and so the exhaust pressure is higher than the intake and part of the exhaust gases can now be sucked back to the intake.

The lp system takes exhaust gases from the exit of the diesel particulate filter (dpf) system, and mixes it with the fresh air intake into the turbocharger. Low pressure loop (lpl) egr systems are effective means of simultaneously reducing the nox emissions and fuel consumption of diesel engines.

An example of a low pressure egr system was disclosed in u.s. These keep the benefits of high pressure egr, as well as adding in a low pressure egr (lp egr) system, sometimes referred to as long route egr. Adapting to different systems and environments is critical to effective emission control.

Further Lower Emission Levels Can Be Achieved By Adopting A System That Combines Lpl Egr With A Nox Storage And Reduction (Nsr) Catalyst.

Among the various solutions for enhanced no x control, low pressure exhaust gas recirculation (lp egr) circuits appear to be an interesting option when compared to traditional high pressure egr (hp egr), selective catalyst reduction (scr) and lean no x traps (lnt), as they allow the egr rate to be increased while controlling intake temperature level with a lower. Low pressure loop (lpl) egr systems are effective means of simultaneously reducing the nox emissions and fuel consumption of diesel engines. The lp egr system is used on eu5 and eu6 market vehicles only.

Low Pressure Egr Systems Draw Low Pressure Exhaust From Downstream Of An Engine's Turbine And Direct The Exhaust To A Location Upstream Of The Engine's Compressor.

Cooled, external exhaust gas recirculation (egr) can be effective for improving fuel economy and for suppressing knock in turbocharged, spark ignition engines [11]. Low pressure egr takes exhaust gas from further downstream of the turbine, often after a dpf, routing it into the intake stream, before the turbo compressor. The egr flow is controlled by the egr valve downstream of the cooler.

The first passenger car automotive application with low pressure egr system was marketed on the vw jetta with a 2.0 liter tdi engine, compliant with tier 2 bin 5 emission. The egr loop inlet is positioned upstream of the exhaust particulate filter and downstream of the turbine to utilize backpressure created by the exhaust particulate filter to insure egr flow in the loop. 2006/0156724 (the '724 publication) by dismon et al.
