Because electric vehicles (EVs) do not generate pollutants during usage, and they can potentially rely on energy provided by a selection of renewable sources, they are the focus of much current interest. However, due to the present capabilities of battery technology, the overall range of such a vehicle is limited. Furthermore, once the battery is depleted relatively long recharging times are currently required before the vehicle is available for use again. Extended range electric vehicles (E-REVs) overcome many of the short-comings of EVs by having a ‘range extender’ unit, which consists of an onboard electric generator powered by an internal combustion engine. In this type of powertrain, the engine configuration either used the spark ignition or compression ignition engines. The engine operation in cold-start conditions can have a significant impact on drivability, fuel economy and tailpipe emissions.
