    Default Mazda to review HCCI engine details later this month

    http://www.motoring.com.au/revolutio...s-soon-108315/

    Mazda is just weeks away from revealing the revolutionary ‘sparkless’ ignition technology that will power the petrol engines in its fourth-generation Mazda3 due in 2018.

    First details of Mazda’s industry-first homogenous charge compression ignition (HCCI) are expected to be revealed at a technology forum in Frankfurt later this month.

    In a new product reveal campaign that will echo that of the original CX-5, Mazda’s first SKYACTIV model in 2011, this month’s HCCI tech forum will be followed by the October Tokyo motor show reveal of a small-car concept that previews next year’s all-new Mazda3.

    However, while it will bring ground-breaking new ‘SKYACTIV II’ powertrains, the replacement for Mazda’s volume-selling small-car will not be based on an all-new platform

    Instead, the 2018 Mazda3 will ride on the same SKYACTIV I platform. This is in line with Mazda’s policy of renewing platforms only every second generation, with a redesigned body (or ‘top hat’) emerging every five years (or so) with each model change.

    Hence, again as per the ‘half new’ MkII CX-5, the successor for the MkIII Mazda3 (launched in January 2014, facelifted in July 2016 and pictured here in a design sketch) will be known internally as a ‘6.5-generation’ model.

    Well, I guess the NA engine will be dead soon. Mazda's next skyactive engine will start incorporating a supercharger.

    http://www.drive.com.au/drive/motor-...ans-64884.html

    “Compression ignition and a supercharger fitted to improve fuel economy together deliver unprecedented engine response and increase torque 10–30 per cent over the current Skyactiv-G gasoline engine,” claims the company

    “Compression ignition makes possible a super lean burn that improves engine efficiency up to 20–30 per cent over the current Skyactiv-G, and from 35–45 per cent over Mazda’s 2008 gasoline engine of the same displacement. Skyactiv-X even equals or exceeds the latest Skyactiv-D diesel engine in fuel efficiency.”
