WHAT IS A HYBRID VEHICLE?WHAT IS A HYBRID VEHICLE?

Any vehicle which combines two or Any vehicle which combines two or more sources of power.more sources of power.

Examples:Examples: Diesel – electricDiesel – electric Nuclear – electricNuclear – electric Gasoline - electricGasoline - electric

HYBRID STRUCTUREHYBRID STRUCTURE

The two power sources found in hybridThe two power sources found in hybrid vehicles may be combined in different vehicles may be combined in different

ways, either in parallel or seriesways, either in parallel or series

Either one will allow the gasoline Either one will allow the gasoline engine to shut down when it is not engine to shut down when it is not

needed.needed.
