Gas turbines are also used for electrical power generation and some ships use a combination: the Queen Mary 2 has a set of diesel engines in the bottom of the ship plus two gas turbines mounted near the main funnel all are used for generating electrical power, including that used to drive the propellers. Some modern ships, including cruise ships and icebreakers, use electric motors in pods called azimuth thrusters underneath to allow for 360° rotation, making the ships far more manoeuvrable. Later, the technology was used in diesel powered icebreakers. The Finnish coastal defence ship Ilmarinen, laid down in 1929, was among the first surface ships to use diesel-electric transmission. Steam turbine-electric propulsion has been in use since the 1920s ( Tennessee class battleships), using diesel-electric powerplants in surface ships has increased lately. The first diesel motorship was also the first diesel-electric ship, the Russian tanker Vandal from Branobel, which was launched in 1903.

Diesel-electric systems are also used in submarines and surface ships and some land vehicles. This kind of power transmission is used on railways by diesel electric locomotives and diesel electric multiple units as only electric motors are able to supply full torque at 0 RPM. ![]() Early examples were buses by Tilling Stevens built in the UK in 1906. No clutch is required.īefore diesel engines came into widespread use, a similar system, using a petrol (gasoline) engine and called petrol-electric or gas-electric, was sometimes used. Diesel engine (left), Generator (centre) and electric motor (bottom right)ĭiesel-electric transmission or diesel-electric powertrain is used by a number of vehicle and ship types for providing locomotion.Ī diesel-electric transmission system includes a diesel engine connected to an electrical generator, creating electricity that powers electric traction motors. ![]() This Metra EMD F40PH locomotive uses a Diesel-electric transmission designed by EMD.ĭiesel-electric transmission system in a modern bus.
