In recent times, one always hears a lot of talk in these two words of the title, but few really know what the difference between these two words. Today’s article will introduce the reader to the differences between these two engine types and to clarify the doubts of those who know just what it is.
The terms Turbocharger and Supercharger refer directly to ways in which the power of an engine can be increased, and is the main focus of drivers’ doubts when they are looking for a way to make that transformation. Taking advantage of this great doubt, our article will also make important considerations about which method is most effective in increasing the horsepower of an engine.
Perhaps the great reason for the controversy between Turbocharger and Supercharger is due to the relative “novelty” in which these terms appeared to the public, since the Brazilian automotive industry only put some type of engine with more performance and consequently the adhesion to these systems in sports cars and luxury, leaving the cars that would be within reach of the great majority without any type of poisoning in its less powerful versions.
That frame has changed from time to time and manufacturers have come up with some more powerful engine options in their most popular models, such as Volkswagen, its Gol Turbo, and Ford with its Fiesta Supercharger. As a result, automakers now offer lower-cost models with more advanced engine options than standard versions.
Continuing the basis of comparison between the VW Gol and the Ford Fiesta, are small and low-displacement motor cars, which have the option of increasing power, but using different systems, and for that to happen, in the case of Gol is used the Turbo and in the case of Ford model, the Supercharger.
In the case of Gol, Volkswagen used the well-known turbocharger system to make Gol’s 1000-cylinder engine start from the 69 rated horsepower for good 112 horsepower with the turbo coupled to the conventional engine system. Just so that the size of the transformation is recorded, the turbo Gol achieves a power equivalent to the engine models that have double the displacement, the 2.0, only with one great advantage: lower weight and fuel consumption.
In the most analytical way, Volkswagen achieved the “magic” by making a few changes to its engine’s injection modules, coupled the turbine to a much richer fuel and used caution in engineering, reinforcing the rear of the engine with forged materials, that with this the engine gained resistance and thus withstand the extra pressure that the turbo proves in relation to the conventional engine.
The system used by Ford is much more ingenious and quite unknown to the vast majority of Brazilians, as it was much more widespread in cars with heavier engines, such as the eight-cylinder or larger, such as V10 or V12, making use of a compressor for the mixture to be fed more richly and thus to obtain the required power gain.
The problem with this type of system is that once the compressors were large, they left the engine heavy and manipulated the fuel well before the intake systems, causing greater danger in heating cases, greater chance of leakage and lower consumption efficiency, completely in newer versions of this system, where smaller compressors work only with the air of the mixture and the fuel is practically injected over the valves. For added safety, there is still an intercooler to cool the temperature generated by the engine and avoid problems.
