Como Mejorar La Eficiencia De Un Carro De Gasolina

It is rather unpleasing to find yourself in the situation of having to buy fuel for your vehicle constantly. It not only bothers individuals, it troubles the whole world, as petroleum is vastly scarce and expensive, with prices ever rising. Not only does this represents a nuisance to the consumers’ pocket, it also illustrates a serious environmental problem, as motor vehicles represents one of the most contaminating machines built by men; these are big contributors to global warming and pollution, with their inefficient engines that require petrol every few hundred miles.

Nevertheless, such issue can be fixed; with incredible technological advances, it won’t be very challenging in a near future. With the use of new, lighter materials, a vehicle’s engine displacement may be reduced in order to achieve a higher fuel efficiency, and optimal in terms of functionality: less energy would be dissipated in pulling the vehicle’s weight and a better use of power can be achieved. Moreover, new materials help in reducing the amount of material used for vehicle composition, so carbon footprint may massively reduce in automobile production plants. Also, new technologies that may help increasing performance and efficiency in a car appear every day, such as superchargers, turbochargers, radial tires and dual-clutch transmissions.

As of today, it seems impossible to make such advances coexist in a single vehicle, as it would be significantly more expensive. However, with the pacey advances in technology every year, prices will soon drop and highly fuel-efficient vehicles will be commonly seen. To find out what such advances are about, research was done on numerous distinct aspects of a car’s functionality.

2.1: Context of how an engine works

How petrol engines work:

Modern car engines work on a principle invented by Nikolaus Otto in 1867, the four-stroke cycle. Basically this means that the whole process of combustion in each cylinder takes, four steps to do a cycle, and then this cycle is repeated over and over again in order to get the energy from the petrol transformed into motion in the crankshaft. The cycle itself starts with the piston at the top of the cylinder, then the intake valves open to let a mixture of air and petrol into the cylinder, while the piston itself moves down in order for the petrol and air mixture to get inside the cylinder chamber. This is the first part of the process, called the intake stroke. After the intake stroke is completed, the piston again moves upwards in order to compress the petrol and air mixture, this part of the process is known as compression. Afterwards, just before the piston reaches the top of its stroke, the spark-plug (a devices that emits an electric current) emits a spark of electricity that allows the mixture
