Hybrid systems: a brief review of the evolution of the technique

Lexus LS 2018

Currently, the hybrid cars along with the electric “pure”, seem to be the panacea in front of a finite resource as is oil. The purpose of these is the to reduce the consumption, which is achieved by attaching an electric motor to one of an internal combustion engine. Without a doubt, these systems are in full boom and all the brands are making great efforts to have a model in their range to incorporate this technology.

We are in the era of technological advancement, and this means not only a renewal of the concepts of computer along with a development of our abilities to control them, but also, a adaptation of our way of life.

The possible potential buyers of any vehicle now have more options than ever to choose from different mechanical. The diversity of the new hybrid systems may prove to be a handicap at the time of purchasing our new car, and it is for this reason, so in this article we want to make a summary of the most important.

Why use an electric motor vs. other types of technologies?

The main weakness of combustion engines traditional is its lack of efficiency at startup and at idle. However, a electric motor can generate its maximum torque from almost zero revs and can to compensate the performance poor at low speed of a traditional mechanical (compressor). On the other hand, a motor thermal, achieves more efficiency to high regimes of laps.

electrical systems allow you to recover energy from the braking or slowdowns and may store it in the batteries. Later, that same energy can power the electric motor; in this way we achieve more energy-efficient driving. In addition to all this, the energy performance of the source of electrical energy (plug-in hybrids) is much higher than fossil fuel; this along with the increased energy efficiency of the motor itself, makes the hybrid systems constitute a very promising option.

do you Drive a hybrid car is like to drive one “normal”?

The answer to this question is, without a doubt, very controversial, because, the great diversity of variants of the hybrid model entails that each one have their peculiarities at the time of driving. We cannot compare a BMW i3 Rex with a Lexus GS450h. Both models are hybrids, and both, intended to resemble as closely as possible to driving a normal car but there are differences.

, While the BMW is a concept car functional, to make a few miles for a comfortable and efficient without neglecting the autonomy, the Lexus has a concept geared to compete with rivals like the Mercedes E-Class or the BMW 5-Series where, in addition to assumed an exquisite ride comfort, seek benefits, aplomb, and of course, autonomy for long journeys.

What is clear is that they all share a premise and it is the “spirit ecologist”. In fact, in none of them is going to miss a cluster of buttons, alerts, messages, and even “mini-games” which assignment will be in a few words, pamper the accelerator and driving in a efficient manner. hybrid systems more common that we can find in the market are the following:

hybrid Systems in series

Sistema-híbrido-serie

Is only the electric motor that drives the car. The heat engine only works as an electrical generator.

hybrid Systems in parallel

Sistema-híbrido-paralelo

Both the electric motor as the explosion, they work in unison. Normally the electric motor is located mid-way between the thermal and the transmission which makes them very effective. This is typically used with combustion engines small where it is intended that the electric motor will support you to increase the power and torque.

hybrid Systems mixed

Sistema-híbrido-mixto

they Are known by the name of systems of distribution of energy. By using a gear, the distribution of the energy is divided between the generator and the engine. When starting and at low speeds, it is the battery that provides the energy while, at normal speeds, the heat engine works with the maximum efficiency and at the same time actuates the generator and recharge the battery.

Conclusion

During the last years, Japan has been a leader in the development of hybrid vehicles; a technology that a decade ago seemed far-fetched when you see it on Honda Insight of 1999. That car raised to think that it served for little more than to show off your “weird car” turns out to have served inspiration european manufacturers have begun to develop supercars as the BMW i8 or the Porsche Panamera E-Hybrid.

therefore, there is one fact that is clear, there are a multitude of technologies couples are being developed, the Hybrid Air PSA, the famous downsizing turbocargados, engines of little more than a liter of displacement that, by 2020, it will employ more than half of the cars sold, or an engine with technology Skyactive from Mazda (they use a high compression in the combustion chamber to to improve the efficiency of the petrol engines in order to stay faithful to their philosophy of naturally aspirated engines), and that is, the hybrid cars have studded in the society and turn out to be profitable for the automobile industry, which entails that the coming years will be really fruitful… this… has not done more to start…
