Transport
Why is transport important?
With the current global climate, conventional road transport systems powered by internal combustion engines (ICEs) suffer ever-tightening restrictions on emissions. Vehicles on UK roads produce an estimated 20% of our greenhouse gases. When you combine this with the scarcity and fluctuating price of oil and the fuel economy and engine efficiency of a vehicle becomes of paramount importance. More efficient engines will reduce these emissions, however considering the maximum theoretical Otto-cycle efficiency of between 35-37%, alternative propulsion systems must also be considered.
Bigger reductions in vehicle emissions and significant efficiency improvements can only be achieved through electric- and hydrogen-based propulsion systems, which are sometimes referred to as ultra low emission vehicles (ULEVs). Low emission vehicles are currently still more expensive than the average ICE vehicle. However, new battery and fuel-cell technology can reduce these costs.
As these electrical energy storage systems improve, the transportation sector can move to broader implementation of electrical propulsion by motors. Fault-tolerance can be included into these electrical machines for safety-critical systems such as seen in aerospace applications. Often such electrical machines can also be incorporated into safety-critical applications such as ABS, power assisted-steering, traction control and steer/fly-by-wire systems.
