The unit pumps controlling fuel flow for each cylinder and injectors optimizing fuel-air mixture means high thermal efficiency, low fuel consumption and reduced exhaust emissions.

In combination with well-matched components optimized for genset applications this gives fast response to load variations and high system efficiency. The reliable and powerful D5A/D7A marine gensets can be delivered with complete classification certificates.
