DENSO creates new EGR valve unit

ABR Staff Writer Published 18 February 2014

Global automotive supplier DENSO has created a new an exhaust gas recirculation (EGR) valve unit to enable diesel engine to produce cleaner emissions.

The new EGR valve unit features an air intake throttle valve and an EGR valve. Air intake throttle valve controls the amount of air entering the engine and the EGR valve controls the amount of exhaust gas to be recirculated into the engine.

The company will equip a new diesel passenger vehicle, to be introduced in Europe later this year, with this new unit.

The new unit is claimed to reduce as it integrates the two valves and needs only one motor and one sensor. The air intake throttle valve and EGR valve are connected through a flexible coupling, cam-link mechanism.

Using the cam-link mechanism, both the valves enable the new unit to meet various engine parameters, including displacement and output.
