Mazda SKYACTIV pursues ultimate performance through engine and electrification

For SKYACTIV Technology, which balances driving performance and environmental performance, Mazda plans to upgrade it to the second generation "GEN2." Mazda said that the second-generation technology will "combine top combustion technology and electrification technology to substantially improve fuel efficiency." It will be put into use from 2016 to 2018 and will be fully introduced in 2019.

Mazda announced at the financial report briefing held at the end of April 2015 a blueprint for upgrading Chuang Chi blue sky to the second generation. With the popularity of models equipped with SKYACTIV's first-generation technology, the average fuel economy of all vehicles sold by Mazda in the world in 2015 increased by approximately 30%. With the adoption of second-generation technology, it is planned to increase this figure to 50% by 2020.

The second-generation technology will be the same as before, with the engine as the center to promote performance enhancement, while actively committing to electrification. In terms of electrification, only the idle-stop mechanism “i-stop” and the deceleration energy regeneration system “i-ELOOP” are currently available on the fuel-engine models, and “Angkesila” equipped with the Toyota Hybrid System is introduced on the Japanese market. (Axela).

In the future, Mazda will aim at the year 2019 and will be equipped with more advanced electrification technology while improving existing technologies such as idling stops.

In the context of increasingly stringent global fuel consumption regulations, there is indeed a limit to the improvement of the engine alone. The Chinese government proposed to increase the average fuel consumption limit of each auto company to 20km/L by 2020. Toyota also promotes hybrid vehicles in China to meet this fuel consumption requirement.

Even Suzuki, which uses small vehicles as its main product, said that "it is not easy to satisfy China's regulations. It will use all means to achieve compliance." Ma Zida, director of the China Business Management Committee, Inabesu Inoue revealed at the Shanghai Auto Show held in April 2015 that “the launch of hybrid vehicles is also one of the issues we discussed”.

How will Mazda, whose operating resources are concentrated on the engine, turn to motorized steering? One of the measures is the package of Toyota and Mazda announced in May 2015. The two sides "will carry out medium and long-term cooperation in all aspects such as environmental protection and security."

President Mazda Komomo Yado said at a press conference, "We will use Toyota's power to improve the value of SKYACTIV." When necessary, Mazda may also borrow the new generation "Prius" hybrid system Toyota plans to launch at the end of 2015, and the world's first mass-produced fuel cell vehicle (FCV) "MIRAI" technology to be launched in December 2014.

The development center of the second-generation engine of SKYACTIV is also known as "Mr. Engine" Mazda engine expert Kazuo Mitsuo. In an interview with Nikkei Motors, Mazda executive director Akira Mitsuo, said, "I am promoting the study of ultra-thin gas mixture self-ignition." There are many areas where the internal combustion engine has not yet clearly grasped the main mechanisms of ignition and exhaust gas treatment, and the thermal efficiency has just reached about 40%. It is hoped that Mazda can develop technologies that subvert past common sense.

In addition, according to market survey data, fuel-powered vehicles will still account for 70% of the total by 2040. Not all of them rely on themselves, but loosely unite with other companies to drive growth. How to survive in chaotic times? Mazda's business strategy or license has brought some inspiration to other car companies. (Reporter: Okawa Minato)
