How does the hybrid engine of a car work?

Hybrid vehicles combine the performance of the internal combustion engine with those of the electric motor, with notable savings in fuel and zero emissions into the atmosphere.

The invention of hybrid engine It arises from the need to improve fuel economy in current vehicles and increase their power, combining the performance of gasoline engines with electric motors. Two power sources that can work together, separately or in parallel, depending on the type of use for which they are designed. But let’s see how a car’s hybrid engine works and what differences exist.

Hybrid engine operation

This type of engine is made up of a series of gears that connect each of the motors to a chain that provides movement to the wheels. The electric motor is the one who starts the movement of the vehicle by turning the outer gear, gaining speed without consuming a drop of gasoline. Instead, from a certain speed, the internal combustion engine is activated by turning the 4 gears of the power divider and increasing the power of the car.

The system is completed with a central gear connected to a generator charging batteries, powered by the gasoline engine and that provides extra power to the electric motor. This is the key to how the hybrid engine works, but let’s look at the two types of engines that exist.

Hybrid in parallel

Although the most common hybrid cars are the so-called hybrids in parallel, there is another typology of series hybrids with notable differences depending on the contribution of the gasoline engine to the movement and the scope of use of the vehicle. That is, depending on whether we usually circulate in the city or on the highway, the hybrid in parallel or in series provides some benefits or others.

In the case of parallel hybrids, both the electric motor and the internal combustion motor are connected to the wheels of the vehicle, being able to work in a joint or separately. This particularity makes them especially interesting from the point of view of consumption and emissions.

Driving in the city, where you don’t need a lot of power, the electric motor allows a remarkable fuel savings and zero emissions into the atmosphere, powered by the energy stored in the batteries installed in the car. These batteries can be recharged while standing still using a outlet or running through the generator coupled to the internal combustion engine. In the latter case, the force reaching the wheels comes from both the electric motor, powered by the electricity produced by the generator, and the combustion engine. An excellent option for those who need more benefits and autonomy on the road.

Serial hybrids

On the other hand, in hybrids serially, the vehicle moves with the power supplied by the electric motor, using the electricity supplied by the generator driven by the internal combustion engine. The advantage of this type of vehicle lies in the performance and autonomy provided by the electric motor in the city, through the generator and the batteries themselves.

Other benefits

Some of the advanced technologies that incorporate this type of hybrid vehicles, whether in parallel or in series, include in regenerative braking. A system to take advantage of the energy consumed during braking and transform it into electricity and then store it in the car’s batteries. The automatic on / off engine or electric motor assistant To provide additional strength in the event of overtaking or sloping roads, these are two of the technologies incorporated in this type of vehicle that are gaining followers day by day.
