When Mazda introduced its new generation of mechanical diesel and gasoline SkyActiv everyone was a little stop. Instead of following the path taken by the vast majority of brands in the market with the downsizing, she decided to throw down the Middle Street. What he did was keep displacements “relatively” high and betting by other techniques such as improve the compression ratio or lower internal friction of their engines.
This series of improvements made to their mechanical achieved data of consumptions and emissions equal to the one of its main rivals without having to invest in expensive technologies. The most common case is that of your mechanical diesel, because they manage to meet the demanding Euro 6 regulation without needing to use the catalytic reduction (SCR) system already used in almost all brands in the market.
Now that seems that the downsizing not is the best road to reduce the emissions and consumption, the brand will continue to betting by its mechanical SkyActiv. According to the signature, the next evolution of these mechanical could arrive to the market under the capo of the new generation of the Mazda 3. All this would be scheduled of face to the next year 2018 and could do that the compact Japanese continue being one of the best in efficiency of its category.
However for this new iteration of their mechanical SkyActiv would come with news as it load homogeneous on by compression (HCCI) that would allow that allows that the mix of fuel and air is make out of the camera of combustion, as occurs in them engines of gasoline of injection indirect. In this case the mixture does not ignite by a spark caused by a spark plug, but that is carried out by the auto-ignition compression of the mixture as in diesel engines.
Applying this system that would make would improve the performance of the engine when will circulate at low rpm and with a level of demand for power medium low since its performance in these circumstances is much greater. In addition, would allow that its NOx emissions and soot particles is less that of a diesel.
In the paper seem to all benefits, we will be attentive to announcements of the brand for its evolution.
