'''Skyactiv''' (styled '''SKYACTIV''') is a brand name for a series of automobile technologies developed by Mazda to increase fuel efficiency and engine output. The initial announcement of the Skyactiv technologies included new engines, but has grown to include transmissions, as well as complete vehicle platforms, which have appeared in Mazda vehicles from 2011 onwards.<ref>{{cite web |date=21 October 2010 |title=Mazda groups suite of new technologies under the "Skyactiv" umbrella |url=http://www.autoblog.com/2010/10/21/mazda-groups-suite-of-new-technologies-under-the-skyactiv-umbr/ |access-date=13 July 2018 |website=Autoblog}}</ref><ref>{{cite web |title=【MAZDA】ニュース |url=http://www.mazda.co.jp/corporate/publicity/release/2010/201010/101020a.html |url-status=dead |archive-url=https://web.archive.org/web/20130517184401/http://www.mazda.co.jp/corporate/publicity/release/2010/201010/101020a.html |archive-date=17 May 2013 |access-date=13 July 2018 |publisher=Mazda}}</ref><ref>{{cite web |title=Mazda Reveals Next-Generation 'SKYACTIV' Technologies – News Releases |url=http://www.mazda.com/publicity/release/2010/201010/101020a.html |access-date=13 July 2018 |publisher=Mazda}}</ref>

'''Skyactiv-X''' is the first commercial gasoline engine to use homogeneous charge compression ignition (HCCI), in which the fuel-air mixture ignites spontaneously when compressed by a smaller, separately ignited charge of fuel. This allows it to reach a compression ratio of 16:1, an improvement over the 14:1 ratio of the Skyactiv-G. The engine can operate much leaner than a conventional spark ignition engine, reducing fuel consumption and emissions.<ref>{{cite web |url=http://www2.mazda.com/en/publicity/release/2017/201708/170808a.html |title=Mazda Announces Long-Term Vision for Technology Development, 'Sustainable Zoom-Zoom 2030' – News Releases |publisher=Mazda |access-date=13 July 2018}}</ref><ref>{{cite web |url=http://www2.mazda.com/en/next-generation/technology/ |title=Next-Generation Skyactiv-X gasoline engine |publisher=Mazda |access-date=2 April 2018}}</ref>

This engine targets 20-30% greater fuel efficiency by utilising HCCI technology. In order to handle ignition problems caused by compression ignition, each cylinder also incorporates a spark plug featuring Spark Controlled Compression Ignition (SPCCI) technology.<ref name="Engineering Explained">{{Citation|last=Engineering Explained|title=Mazda Creates The Holy Grail Of Gasoline Engines – HCCI SkyActiv-X|date=2017-08-13|url=https://www.youtube.com/watch?v=9KhzMGbQXmY|access-date=2017-08-13}}</ref>{{Better source needed|Source mostly summarizes Mazda press release.|date=February 2023}} A small Roots-type supercharger further expands the compression ignition operating window by feeding more air into the engine, leaning out the mixture sufficiently for compression ignition even at higher speeds.<ref>{{cite magazine |url=https://www.caranddriver.com/reviews/a15081390/2019-mazda-3-with-skyactiv-x-compression-ignition-gas-engine-prototype-drive-review/| title=Driving Mazda's Next Mazda 3 with Its Skyactiv-X Compression-Ignition Gas Engine |magazine=Car and Driver |access-date=29 January 2021}}</ref>

SPCCI works by drawing in a lean, homogeneous air-fuel mixture, it then compresses the mixture until it approaches the point at which it would spontaneously detonate. A second injector then adds a secondary charge of fuel directly on the spark plug. This secondary charge is ignited by the spark plug, causing the cylinder pressure to very quickly rise to a point where the rest of the fuel undergoes compression ignition. The presence of the spark plug allows the engine to also operate as a spark-ignition engine under some operating conditions, such as high-speed high-load situations. Revealed June 5, 2019, the output is {{cvt|132|kW|PS hp|0|abbr=on}} and {{cvt|224|Nm|lbft|0|abbr=on}}.<ref name="Engineering Explained" />

Mazda is developing an inline-six variant of the Skyactiv-X, with displacements of 3.0 and 3.3 liters and a rear-wheel-drive layout. It was believed that production of the new engine would begin in 2022 with the Mazda CX-60.

[[File:MAZDA ATENZA SEDAN GJ XD L Package 03.JPG|thumb|Skyactiv-D (SH-VPTR) Diesel engine (For Mazda 6)]] '''Skyactiv-D''' is a family of turbocharged diesel engines, designed to comply with global emissions regulations.

To eliminate the need of NOx and particulate treatment in contemporary diesel engines, the cylinder compression ratio is reduced to 14.0:1. Cold engine start is achieved via multi-hole piezo injectors with 3 programmable injection patterns, and adoption of ceramic glow plugs. Engine misfiring is prevented via variable valve lift at exhaust, which opens exhaust valves during the intake stroke, which in turn increases engine air temperature. The Skyactiv-D also uses a two-stage turbocharger, in which one small and one large turbo are selectively operated, according to driving conditions.

=== Unique technology === The Skyactiv-D is the first low compression diesel in a production car, having a significantly lower compression in the first generation of 14:1 rather than typical compression ratios of 16:1 and beyond.<ref name="Difference Engine: Born again">{{Cite news|url=https://www.economist.com/babbage/2013/07/08/difference-engine-born-again|title=Difference Engine: Born again|date=2013-07-08|newspaper=The Economist|access-date=2019-05-02|issn=0013-0613}}</ref> Numerous university studies have investigated the benefits of low compression diesel for decades, with the major benefit, noted in single cylinder university tests, being a drastic reduction in NOx emissions while also reducing particulate matter and combustion noise.<ref>{{Cite journal|last1=Pacaud|first1=P.|last2=Perrin|first2=H.|last3=Laget|first3=O.|date=2009|title=Cold Start on Diesel Engine: Is Low Compression Ratio Compatible with Cold Start Requirements?|journal=SAE International Journal of Engines|volume=1|issue=1|pages=831–849|doi=10.4271/2008-01-1310 |issn=1946-3936|jstor=26308324}}</ref><ref>{{Cite web|url=https://www.researchgate.net/publication/290496580|title=A survey on low compression ratio diesel engine|website=ResearchGate|access-date=2019-05-02}}</ref> These studies all concluded that while there were noticeable reductions in emissions, this came at the expense of difficult cold starts. Mazda resolved this in the Skyactiv-D by using piezoelectric fuel injectors with multiple nozzles that change their pattern depending on operating conditions. Furthermore, exhaust valves are left slightly open as the engine starts, causing exhaust gases to be sucked into the cylinders and help the engine warm up quickly.<ref name="Difference Engine: Born again" />

=== Early issues === The CX-5 with Skyactiv-D engines were reported to have oil levels rising earlier than expected upon release, which required owners to check the vehicle's engine oil every 1000 kilometres or every month and return to the dealer if the oil appeared over the level of the dipstick.<ref>{{cite web |url=http://news.drive.com.au/drive/motor-news/backlash-over-mazda-cx5-diesel-oil-issues-20120821-24k6w.html |title=Backlash over Mazda CX-5 diesel oil issues |website=Drive.com.au|access-date=13 July 2018 |archive-url=https://web.archive.org/web/20140306014721/http://news.drive.com.au/drive/motor-news/backlash-over-mazda-cx5-diesel-oil-issues-20120821-24k6w.html |archive-date=6 March 2014 |url-status=dead}}</ref> This procedure was initiated by Mazda worldwide as a precaution. Mazda resolved the issue in the first few months of the engine's availability via a software revision and a new dipstick with a corrected level.{{citation needed|date=May 2020}}

This was later found out to be false, the core issue being the injector seals – the method Mazda employed to secure these did not result in sufficient clamping force whenever a low-temperature Diesel Particulate Filter regeneration cycle was triggered, leading to exhaust leaking into the valvecover and contaminating the oil. In addition, it also overpressurized the engine block resulting in high volumes of unmetered fuel/oil mixture re-entering the combustion chamber.{{citation needed|date=March 2025}}

The end result was either a clogged oil pickup resulting in engine failure, or a very costly feedback loop of extreme cylinder pressures, clogged up intake manifold, ash filled particulate filter, the exhaust- and intake manifold pressure sensors, and a skyrocketing fuel consumption due to near constant regeneration cycles.{{citation needed|date=March 2025}}

Mazda officially refuses to acknowledge this, except for the Australian market,<ref>{{cite web |url=https://www.aaaa.com.au/news/mazda-recalls-35000-diesel-powered-vehicles/ |title=Mazda Recalls 35,000 Diesel Powered Vehicles |website=Australian Automotive Aftermarket Association|date=15 October 2019 |access-date=March 8, 2025 |archive-url=https://web.archive.org/web/20200323021009/https://www.aaaa.com.au/news/mazda-recalls-35000-diesel-powered-vehicles/ |archive-date=23 March 2020 |url-status=live}}</ref> even though there are several different Mazda Service Information documents on the issue, and resolving it. Most notably M001/007A which documents the new SHY1-13-148A injector nut/washer fastening procedure.{{citation needed|date=March 2025}}

=== Emission standards and tests === At launch in 2012, Mazda claimed the Skyactiv-D engine would only comply with Euro 5 emission standards (NOx of 0.18 g/km), and further work was required to achieve stricter emission standards.{{citation needed|date=June 2020}}

In the aftermath of the Volkswagen emissions scandal, the Japanese government performed testing of all diesel engines produced in Japan to ensure Japanese manufacturers were not falsifying emissions as had been done by Volkswagen. It was determined that the Skyactiv-D engine was the only engine which tested at or near the standard.<ref>{{Cite magazine |url=https://www.forbes.com/sites/bertelschmitt/2016/03/05/japan-releases-nasty-diesel-test-results-germany-sits-on-them/ |title=Japan Releases (Nasty) Diesel Test Results, Germany Sits On Them |last=Schmitt |first=Bertel |magazine=Forbes |date=5 March 2016 |access-date=2 May 2019}}</ref>

=== Recall === In September 2016, Mazda recalled 130,000 vehicles in Japan over a defect that could lead to diesel engine failure.<ref>{{cite news |url=https://www.bloomberg.com/news/articles/2016-09-01/mazda-recalls-japan-diesel-models-after-846-consumer-complaints |title=Mazda Recalls Japan Diesel Models |last1=Horie |first1=Masatsugu |publisher=Bloomberg L.P. |date=1 September 2016 |access-date=1 October 2016}}</ref>

Although most problems were fixed later on, the 2.2 suffered from bad carbon build up that would block the intake manifold. Other faults include a turbo diversion valve failure that required replacement of the complete twin turbo unit.

Mazda recalled the 2012 to 2018 model year diesel Mazda 3, Mazda 6 and CX-5 because of a build-up of carbon deposits.<ref>{{cite news |url=https://www.caradvice.com.au/799235/mazda-3-6-cx-5-recalled/#:~:text=Mazda%20Australia%20has%20issued%20a,wear%20of%20certain%20engine%20components.&text=Potential%20engine%20stall%20with%20no,emit%20from%20the%20engine%20compartment |title=Mazda 3, 6, CX-5 recalled |website=CarAdvice.com |access-date=10 June 2020}}</ref>

The new Skyactiv automatic transmission is designed to have six or eight gears forward, one reverse gear, a short torque converter, and a clutch integrated with the torque converter.<ref>{{cite web |url=http://www.motorauthority.com/news/1064742_mazda-rejects-dsgs-redefines-automatic-transmissions-instead |title=Mazda Rejects DSGs, Redefines Automatic Transmissions Instead |first=Bengt |last=Halvorson |website=Motor Authority |publisher=High Gear Media |date=8 October 2011 |access-date=2 April 2014}}</ref><ref name="CX-60" />

== Skyactiv-MT == '''Skyactiv-MT''' is a family of manual transmissions. To achieve lighter shift effort with a short shift lever stroke, the lever ratio is increased. However, to overcome the shorter internal stroke, a small module spline is used.
