there is a “war” of technological innovations is obvious. So much so that sometimes you start to crave that time when we were kids where the diesel was only used for heavy machinery, and cars that were made many kilometers. These were more economic their use, against undermining the comfort of the passengers. While gas, reserved to the few who are just “touched” the car, or, for those more affluent who could afford a sedan or suv is the most luxurious.
This picture has changed completely, we are all aware of it… and without realizing it we see taxis gasoline-fueled, trucks, hybrids, and even some cars with solar panels on the roof… How do we organize all this? is Not an easy task especially if one is not embedded in the latest news. Not to worry, because today let’s make a brief summary of these innovations that brands use to captivate our attention ecologist.
As we said back in the day, the hybrids are the vehicles that employ a heat engine (conventional) along with an electric motor siding with the first in order to reduce the consumption; so much so, that a gasoline hybrid offers a consumption figures and emissions of CO2 similar to those of a diesel.
- Pros: your starting price is a little higher than that of a normal car, urban consumption is low.
- Cons: battery capacity is very limited, noisy, especially those that incorporate transmission drive continuous (CVT).
Denomination used by some manufacturers and which can lead to confusion. It is employed to designate some technologies that help to reduce the consumption as is the Stop&Start. However, in the present there are models that use this name to assign to those who incorporate a small electric motor under the hood assists the gasoline in a very timely; this is the case of the Suzuki Positioned 1.2 SHV whose lithium-ion battery and is only 0,36 kWh of capacity. This system will mount also the next generation of the Suzuki Alto.
- Pros: the “gadgets” tend to come from series, save fuel mainly in a urban use.
- Cons: the batteries are more expensive to replace (AGM), sometimes it does not take advantage of its effectiveness and even, in stops, continuous and short, can be annoying.
Also so-called PHEVS, they have the good of both worlds. On the one hand, the performance of the heat engine are always patent, and on the other, they can travel up to 40Km in electric mode, being completely silent and without consuming fuel; in addition, its batteries are recharged in a few hours on a plug is conventional.
- Pros: almost same tax incentives that the electrical short routes have the same advantages as that of a 100% electric.
- Cons: cost 20% more than average.
Without a doubt, the electric ones seem to break with the discourse clean and irrevocable of any heat engine. However, must not forget the source from which comes that power; mostly, in countries such as Spain, it is of fossil fuel is also polluting and scarce so that we could say that contaminate indirectly.
- Pros: great economy of use and respect of a direct way for the environment.
- Cons: price above the average, autonomy is still low.
Is the technology with more “future”. It is still in the experimentation phase, but there are already cars that incorporate it such as the Honda Clarity Fuel Cell or the Toyota Mirai. The foundation of its operation is in the reaction exergonic that occurs when you mix hydrogen (the fuel) with oxygen (combustion air) is taken from the environment; this energy to recharge the batteries that feed the electric motor.
- Pros: not contaminated (only the process of obtaining the hydrogen, refuelling fast (3 minutes), low maintenance.
- Cons: purchase price expensive, hydrogen is not cheap, there is no infrastructure, hazards due to breakage of the tank of hydrogen in the event of an accident.
can Be to use in the petrol models doing a modification in the injection. Actually, consumption is environment a 10-15% lower than those of a vehicle of gasoline.
- Pros: the fuel price is lower, there are 541 service stations in Spain, a high level of autonomy, aid for the purchase in 2017.
- Cons: it occupies a lot of space, it is not the most efficient technology, increases the weight of the vehicle, there are few models on the market that they can incorporate it from the factory.
Is making engines of small displacement, lighter, with less internal frictions and that consume less fuel. To mitigate the loss of power, they associates a turbo or a compressor. Along with this measure, the manufacturers have chosen to reduce the number of cylinders, usually in 3 but we can see models with 2-cylinder and the 0.9 TwinAir from Fiat. It is expected that for the next decade, more half of the cars use this technology.
Consists of a system for the engine when the car stops. effectiveness begins to be noticeable from the 6 seconds after the engine’s shutdown. Cars with Stop&Start feature a starter motor reinforced and normally lead AGM batteries that can be up to 50% more expensive than conventional ones.
it Is a liquid compound (ureaAUS32) whose catalytic reaction (RCA) eliminates the NOx in the exhaust of diesel vehicles. Currently the regulations require diesel engines of more than 2.0 litres to carry this system.
Consists of a number of messages, visual alerts that are associated with the on-board computer and suggest the driver’s way of driving more optimal for each moment. Currently the number of cars that incorporate it does not reach the 10%.
These are some of the technologies more usual, and striking that car manufacturers are implementing to their cars to to be able to adapt to the new regulations european antipollution. Some are well known and their effectiveness is demonstrated. However, other as is the case of hydrogen, the cars that are in circulation could be the “guinea Pigs” of what we will see in the future, as in its day it was the Audi Duo III, or the first generation of the Toyota Prius in the case of hybrids.
