Hybrid Cars

A hybrid vehicle, more properly vehicle propulsion hybrid, a vehicle is equipped with two systems of propulsion, for example electric motor with heat engine, the mated more widespread. Some define it as the hybrid vehicle also thermal flex ( petrol / LPG, petrol / CNG, diesel / kerosene, petrol / hydrogen ).

This technology is very similar to that used in locomotives diesel-electric. In this type the heat engine is not connected to the wheels, it has the task of generating the current to power the electric motor that turns in motion, while the superfluous energy is used to recharge the batteries.

In the moments when prompted for a large amount of energy, it is drawn from both the heat engine that from the batteries. Because the motors are able to operate on a large vastness of regimes of rotation, this structure allows to remove or reduce the need for a transmission complex. The efficiency of internal combustion engines changes to vary the number of revolutions, in systems series hybrid the engine speed thermal are set to obtain the maximum efficiency by not having to suffer neither acceleration nor deceleration. Given this condition and to compensate for the additional energy transformation, one can use a heat engine (generator) that has a strip of exploitation / operation very narrow compared to the total schemes and that for this to have a higher efficiency of heat engines classics, for at least in the rev range.

In some prototypes have installed small electric motors at each wheel. The advantage of this configuration is to control the power delivered to each wheel. One possible purpose could be to simplify the traction control or on / off four-wheel drive.

The major drawback of the hybrid series is the serious reduction efficiency than the engines only in conditions of high heat and constant speed (as do the 130 km / h in highway ). This is caused by the fact that the thermal-electric-bike conversion of the energy is lost as it would not happen with a direct drive. This drawback is not present in the parallel hybrid . The hybrid series are the most efficient for vehicles that require continuous brakes and starts like cars for urban use, bus and taxi.

Many models of hybrid series are supplied, in a button to turn off the engine. The function is especially useful for the circulation in restricted traffic zones. The autonomy is limited to the charge of the batteries, the heat engine, however, can be reactivated by pressing the same button. The diesel engine is also switched off automatically during stops.
