Economic power

    Utilises advanced combustion technology to deliver durable and reliable power

•    High commonality of components with other engines in the 4000 Series family for reduced stocking levels

•    Individual large valve cylinder heads with matched deep bowl pistons for greater swirl, achieve high mechanical efficiency

Reliable power

    Developed and tested using the latest engineering techniques

•    Piston temperatures controlled by an advanced gallery jet cooling system

•    Extended durability and attention to reducing servicing with extended component life add benefit of the reduced whole life cost

•    Robust to varying gas quality

Compact, clean and efficient power

    Exceptional power-to-weight ratio and compact size give optimum power density for ease of transportation and installation

•    In excess of 40% mechanical efficiency

•    Designed to provide excellent service access for ease of maintenance

•    All engines in the 4000 Series family are capable of meeting the NOx requirements of TA Luft
