Other features of this state-of-the-art unit include an advanced high-pressure fuel system and Variable Valve Timing (VVT), ensuring full flexibility; a four-valve dual overhead camshaft (DOHC) arrangement; variable swirl intake ports and a primary and secondary balanced cranktrain.

This advanced research machine, together with the laboratory equipment also supplied, will support DFCV fundamental research and investigation on key areas such as efficient and low soot combustion systems, combined precise injection, exhaust gas recirculation (EGR) and boosting strategy, all of which are instrumental to the development of next-generation clean and fuel efficient diesel engines for heavy duty applications.
