It salvages the heat wasted in the exhaust and radiator (as much as 80% of heat energy) and uses a steam piston or turbine to relay that power to the crankshaft. The steam circuit produces 14 hp (10 kW) and 15 ft⋅lbf (20 N⋅m) of torque at peak (for a 1.8 straight-4 engine), yielding an estimated 15% gain in fuel efficiency .
The compressor increases the flow of hot air which increases the rate of heat transfer to the water in the boiler tubes causing more steam to generate. The steam is used to turn a steam turbine which is coupled to an electrical generator. [3] The combustion chamber of the Velox could produce flue gasses by burning fuel gasses or heavy fuel oil.
A steam turbine from MAN SE subsidiary MAN Turbo. In general, the two kinds of turbomachines encountered in practice are open and closed turbomachines. Open machines such as propellers, windmills, and unshrouded fans act on an infinite extent of fluid, whereas closed machines operate on a finite quantity of fluid as it passes through a housing or casing.
Turbo generators are used for high shaft rotational speeds, typical of steam and gas turbines. The rotor of a turbo generator is a non-salient pole type usually with two poles. [5] The normal speed of a turbo generator is 1500 or 3000 rpm with four or two poles at 50 Hz (1800 or 3600 rpm with four or two poles at 60 Hz).
This low steam turbine entry temperature (compared to a gas turbine) is why the Rankine (steam) cycle is often used as a bottoming [clarification needed] cycle to recover otherwise rejected heat in combined-cycle gas turbine power stations. The idea is that very hot combustion products are first expanded in a gas turbine, and then the exhaust ...

The T-series engine also found its way into limited-run Rover 220 3-door hatchbacks in GTi and later GSi trims and the 420 GSI turbo and GSI Sport turbo. The T-series engine is a popular engine for engine conversions in to other Rover- MG vehicles i.e. MG ZR , MG ZS etc.
An extension of the standard turboelectric propulsion scheme is COGES, or combined gas–electric and steam. In COGES a gas-turbine–electric primary transmission is used with a heat-recovery boiler in the exhaust flow to generate steam that drives a steam turbine that also generates electricity. Thus the system is thus even more efficient, as ...
