The full toroidal traction IVT technology gives the following generic benefits. To learn about the specific benefits the IVT brings to different markets and applications, click on the appropriate section of this website.
Running an engine at optimum conditions
The exceptional ratio range of the IVT provides an almost total decoupling of engine and vehicle speed. For any given power demand the IVT will operate the engine at a pre-determined torque and speed, largely independent of vehicle speed. This ensures that the engine always operates at minimum specific fuel consumption, i.e. at maximum efficiency. Typically, this means that the engine operates at low speed (reduced friction losses) and high torque (reduced throttling losses).
‘Geared neutral’
The IVT has a feature termed ‘geared neutral’ where the engine can be connected to the road wheels whilst the vehicle is stationary (for information on how this is achieved please see the epicyclic page in the ‘How It Works’ section). This feature delivers a number of benefits including:
No need for an inefficient starting device such as a torque converter.
- Continuous torque at the wheels.
- Accurate control of the vehicle at low speeds.
