The Cummins KTA38 is a 12-cylinder, V-configured, 38-litre diesel engine delivering up to 1,119 kW. It is widely used in marine propulsion, offshore vessels, mining haul trucks, and power generation. Its robust design makes it highly serviceable, but major overhauls require careful planning and the right parts.
