In a gasoline engine the fuel-air mixture is ignited by a spark from the spark plug. To explain how SKYACTIV-X works, weвЂ™ll first need to cover some engine basics. ThatвЂ™s why SKYACTIV-X is such an important breakthrough in MazdaвЂ™s goal to reduce вЂwell-to-wheelвЂ™ carbon dioxide emissions to 50 percent of 2010 levels by 2030, and a staggering 90 percent reduction by 2050. Of course, Mazda plans to introduce electric vehicles to areas that have clean energy sources and will add hybrid and plug-in vehicles, but the internal combustion engine will continue to be the base power unit for 85 percent of all cars up until 2035. This technology considers real-world emissions over a carвЂ™s entire life cycle. This revolutionary engine, a world first, employs a method of combustion вЂ“ compression ignition вЂ“ that the combined might of the motor industry has been trying to master for over two decades. One part of this bold plan is SKYACTIV-X. MazdaвЂ™s вЂwell-to-wheelвЂ™ approach to reducing emissions considers fuel extraction, manufacturing and shipping as well as driving. Reducing greenhouse gas emissions is not simply a case of switching cars to electric power вЂ“ at least until the whole world runs on renewable energy. вЂњWe have pledged to build a future in which we can coexist with the bountiful, beautiful earth by applying a well-to-wheel philosophy to achieve substantive cuts to carbon dioxide emissions,вЂќ Masamichi Kogai, President & CEO, Mazda SKYACTIV-X: a revolutionary new combustion engine
