What is engine downsizing?

Those who follow the automotive market know that, over the decades, the search for the reduction of contaminating emissions, the reduction of fuel consumption and the increase in the performance of vehicles were the main responsible for technological transformations in this sector; This is what happened, for example, with pistone rings. With engine downsizing, the mission is no different!

To achieve this, this trend, which is slowly taking hold in automobile factories around the world, consists of reducing the size of the engine to improve the france phone numbers efficiency of the automobile. The central idea is to maintain power, torque and accelerator response so that the driver does not feel that fuel consumption is associated, for example, with reduced vehicle agility. This is where 3-cylinder engines come into play.

The role of the 3-cylinder engine
Firstly, we must remember that “downsizing” is a rendered English word and means size reduction. Clarifying this origin is important because, in many cases, the concept of reducing the size of the engines is faced with fear: does it mean that the engine of your car will be smaller, with smaller parts and reduced power? It's not exactly like that.

Among other things, because downsizing technology, despite being increasingly popular, is not necessarily a novelty for those dedicated to automotive engineering. Instead of creating “miniature engines”, the concept is more related to the development of solutions that can offer more with less . This is the case for 3-cylinder engines.

Taking this conversation directly to the mechanical workshop and adopting the old and beloved Spanish, the idea of ​​creating an engine without 4 series cylinders is putting into circulation a car that “consumes” less fuel. Just make some calculations: if a smaller amount of fuel is burned, the emission of contaminants decreases, as does the consumption of gasoline, alcohol and the like.

Furthermore, this type of engine, with its more modern reorganization, brings other advantages that are noticeable throughout the useful life of the vehicle, such as the reduction of total weight and internal friction. Everything is very fascinating and innovative, that's for sure. But, in all this scenario, what happens with the performance? Ultimately, a 3-cylinder engine is unable to offer the performance and speed of a 4-cylinder engine, right?

A few years ago, it could have been true. This is due to the fact that, for a long time, the power and torque of automobile engines were associated with a greater number of liters and number of cylinders. In general, a “larger” engine was more powerful than a “smaller” one. However, the scenario changed with the arrival of the turbocharger and direct fuel injection, technologies that open new horizons for small-sized engines.
