A major new family of mid-range diesel engines, designated Q14, which are primarily turbocharged with charge-cooled and naturally aspirated options, has been designed by Perkins Engines Group to meet the needs of on and off-highway applications. The family of 3, 4, 5 and 6 cylinder inline engines will initially be brought to production with a top rating of 170 kW.
The ever more stringent and in some cases contradictory requirements of today's market place have received assiduous attention during the evolution of the engine. Design, development and manufacturing needs have been closely coordinated to ensure a product that meets all requirements including all current and proposed controls on gaseous emissions, smoke and noise, even at high volume production, but which still has a satisfactory cost structure.
In this paper the six cylinder engine concept and design are described together with the subsequent engine application development.
