YOUR INTRODUCTION TO MAN EFFICIENTHYBRID
The virtually wear-free MAN EfficientHybrid automatic start-stop system offers you even more economic advantages. Thanks to our smart energy management system, the diesel engine switches off when the vehicle stops, while the energy generated during every braking process is converted into electrical supply. The utilised braking energy relieves the diesel engine and reduces emissions, wear and fuel consumption.
Good connection: Efficiency and ecology
We pave the way for intelligent energy management everyone can benefit from.
The courage to try something new is the best drive. MAN EfficientHybrid, for example, puts you three times ahead: fewer pollutant and noise emissions, lower fuel consumption and less wear. All this is achieved by a well thought-out system that uses energy that would otherwise be wasted.
Space for innovation
A robust and wear-free electric motor is used between the engine and the gearbox. It serves as a crankshaft starter generator and – together with an UltraCap energy accumulator system placed on the roof and a smart control system – increases the energy efficiency of your buses.
A hybrid through and through
By the way: City buses with MAN EfficientHybrid are officially registered as hybrid buses. This is a clear advantage for every city – also paying off in terms of image.
It is connected to the flywheel housing of the engine and works both as a generator and as an electric starter.
Since the conventional starter is not needed for these starting processes, its service life is significantly extended.
When the bus brakes, it generates electricity through the resulting mechanical energy.
When starting, it converts the previously gathered electrical energy back into kinetic energy.
The 48 volt UltraCap energy accumulator is made up of multiple individual cells with high-performance capacitors.
The high-performance capacitors are able to store and release high amounts of electrical energy particularly quickly. Plus, they are lighter and more compact than conventional rechargeable batteries.
Here, electrical energy is stored electrostatically, this means without chemical processes as with conventional batteries.
The self-learning energy management system uses energy where it is needed most.
While stopped, it supplies the vehicle electrical system. While driving, it supports – depending on the amount of stored electricity – the diesel engine with electric drive power.
The goal: maximum possible savings in fuel consumption and pollutant emissions.
