Denso says it has developed a compact exhaust gas recirculation (EGR) valve unit, a major component of EGR systems that helps make diesel engine emissions cleaner.
The new unit, which Denso claims is the first in the world to integrate an air intake throttle valve and an EGR valve, is half the size of conventional models and requires fewer components.

The unit will be installed in a diesel passenger vehicle to be sold in Europe from later this year.
