This enabled the vehicle to be used for revenue service where there was no contact wire. The trolleybus was fitted with an internal combustion engine (ICE) to power the mechanical drivetrain directly, not to generate electricity for the traction motor. One of the earliest forms of hybrid land vehicle was the 'trackless' trolleybus experiment in The United States (New Jersey) that ran from 1935 to 1948, which normally used traction current delivered by wire.
A diesel–electric powertrain fails the definition of hybrid because the electric drive transmission directly replaces the mechanical transmission rather than being a supplementary source of motive power. For example, a hybrid may receive its energy by burning gasoline, but switch between an electric motor and a combustion engine.Įlectrical vehicles have a long history combining internal combustion and electrical transmission – as in a diesel–electric power-train – although they have mostly been used for rail locomotives. A hybrid vehicle has multiple forms of motive power. Hybrid vehicle drive trains transmit power to the driving wheels for hybrid vehicles.
Systems vehicles with multiple power sources use to transmit power to the wheels
