How Advanced EGR works to reduce emissions in the engine.
When temperatures in an engine's combustion chamber get too hot, oxides of nitrogen (NOx) form. When NOx combines with hydrocarbons, they produce the ugly haze we call smog. EGR (Exhaust Gas Recirculation)re-circulates this exhaust back into the intake stream. Since the exhaust gases have already combusted, they don't burn again. These gases displace some of the normal intake, slowing and cooling the combustion process, which reduces NOx formation.
The challenge in reaching 2010 levels of emissions is to precisely control the flow of re-circulated exhaust. MaxxForce Advanced EGR engines achieve that goal with increased injection pressure, improved combustion and refined calibrations. The result is an engine that treats NOx in-cylinder, and therefore requires no extra effort from our customers.
MaxxForce Advanced EGR is a better solution:
- It reduces emissions without having to use added fluids
- It doesn't require extensive new training for drivers and mechanics
- It doesn't require operational changes for drivers
- It doesn't require any change in maintenance and service requirements for mechanics
