The marine propulsion system on a vessel is the mechanism or system used to generate thrust to move a ship or boat across water, it can be as simple as a diesel engine directly connected to a propeller shaft, which drives the propeller, or more complex systems containing diesel engines powering an electrical generator, supplying electrical power to an electrical motor through a sophisticated control system.

The powertrain system consists of the internal combustion engine, transmission and differential/axle assembly. As the heart of all machines, engine power pack is only the power resource, the engine power pack convert the chemical energy into rotating power, but how to transfer the rotating power into driving power of the vehicles or other industrial machines?

Engine power pack is a complete engine system that ready to provides power output without any additional accessories.
Diesel engine, as the core power source of all mobile machines, has been widely using in automotive, industrial, maritime, energy fields, railways, oil and gas field.
