The idea behind this approach is that cEGR
is more important for fuel efficiency at mid and high loads (initial state of the tip-out) compared to hot internal residual.

These technologies include dual turbochargers, cooled exhaust gas recirculation (cEGR
), selective catalytic reduction (SCR), and diesel oxidation catalysts (DOC) to clean emissions in the exhaust system without interfering with engine performance.
Marringa added, "Because excavators run with little change to engine speed, CEGR
technology was the best choice for efficiency and convenience."
These recent gasoline examples as well as others [20, 21, 22] using different approaches (dedicated EGR; Miller cycle, high compression ration, cEGR
; compression ignition) show that gasoline engines have much room for improvement with many different concepts and are approaching modern diesel engine efficiencies.
The CX210D meets Tier 4 Final emissions standards through a combination of cooled exhaust gas recirculation (CEGR
), selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) technologies.

The SCR design on the 621F and 721F also contributes to machine uptime by eliminating the need for manual diesel particulate filter (DPF) regeneration and the associated downtime that occurs with wheel loaders that use cooled exhaust gas recirculation (CEGR

It features Tier 4 Interim-certified cooled exhaust gas recirculation (CEGR
) technology that burns cleaner while delivering superior horsepower.

CNH agricultural equipment features two technologies to meet the Tier 4 emissions standards without compromising engine performance: selective catalytic reduction (SCR) for medium- and heavy-duty engines, and cooled exhaust gas recirculation (CEGR
) for light-duty engines (less than 100 horsepower).
