In short, the Komatsu S4D102E-1 engine and Cummins 4BT3.9 engine use the same basic engine components (cylinder head, valves, valve inserts, block, crankshaft, con-rods).

​We can distinguish the diesel engines by application. We mean that a diesel engine that is placed in a ship has a different specification than a diesel engine that is used as a generator set, pump set, power pack or another industrial application.

The transportation industry is navigating the delicate balance between performance enhancement and sustainability. A pivotal aspect of this journey is the evolution of engine braking and Valvetrain technologies due to the direct link these components have with engine performance and fuel consumption. This article helps explain the latest developments around braking and Valvetrain technologies, and how they are contributing to improved performance while complying with emissions regulations.
