What is?
Chong Chi blue sky (SKYACTIV) is a series of techniques proposed by Japan’s Mazda Motor Corporation in 2010, the main components of the technology engine, gearbox, chassis, body structures, etc. Its models were optimized. to achieve the “fun to drive” and “outstanding environmental and safety performance” harmonious balance.

Engine Technology
petrol engine (SKYACTIV- G-type engine)
2011 launched in Japan on June 30 facelift third generation Demio, equipped employed SkyActiv 1.3LSKYACTIV-G of the engine that the injection system is equipped with six holes, and enhanced air flow to enhance injection pressure, in order to improve combustion efficiency. Concave top piston design, the stroke near the spark plug in the stack gas mixture after the fuel injection, help stabilize combustion. Compression ratio of 14.0 to 1 for the first time to achieve mass production of gasoline engines, engine efficiency, fuel consumption, torque increased by 15% or more.
Diesel engine (SKYACTIV-D type engine)
SkyActiv compressed Diesel ratio decreased to 14.0: 1, but also reduce its temperature and pressure. Since the ignition timing is extended, air is mixed with fuel that contributes to the uniform combustion, it is possible to reduce carbon monoxide, hydrocarbons, nitrogen oxides, and other solid particulate matter caused by air pollution. Further, since the combustion chamber near top dead center in the injection, combustion, so the work efficiency is much higher than the average compression ratio of the diesel engine higher. Relatively speaking, the lower the compression ratio and the thickness of the cylinder can be reduced into aluminum, lightweight machine canOf. The diameter of the crankshaft main journal shortened from 60mm to 52mm, not only to reduce the 25 percent by weight, mechanical resistance also decreases.

Transmission Technology
Automatic Transmission [ 123] Chong Chi blue automatic transmission gearbox (SKYACTIV-dRIVE) on the basis of the hierarchical aT, striving for “low fuel consumption”, “direct drive feeling”, “smooth shift” to set all of the advantages of various transmission the transmission is an ideal target.
Full region is locked to reduce fuel consumption, directly driving sense. The torque converter is a step-by AT liquid engine is transmitted to the power transmission, it is possible to realize smooth starting and shifting. However, since the liquid power transmission loss, and will lead to increased fuel consumption of the engine before the vehicle speed is increased to improve the “slip teeth” phenomenon, therefore, designers have provided in the torque converter lock-up clutch, not through the liquid , rely on mechanical engagement to deliver torque.
manual transmission
Chong Chi blue manual gearbox (SKYACTIV-MT) implemented as light car as neat shift-tempo, compact, lightweight pre-precursor (FF) generation type manual transmission that require low operating stroke and the dual advantages of light. By adjusting the structure, to achieve a lightweight and compact substantial transformation. Compact size, more efficient use of the layout of the vehicle body, by reducing the internal resistance, improved fuel economy.
The vehicle body structure
Chong Chi blue vehicle collision safety performance to the top level. A new generation of lightweight high-rigidity body, and better support from the “fun to drive” this appeal. Along with the dual advantage of high rigidity and weight reduction (weight loss percentage of 8, 30 to enhance the strength percentage). Adopt a “linear structure” consisting of a straight line as much as possible on the base frame, coordinate ministriesPortion into full play “continuous structure.
Chassis
In order to achieve Chong Chi blue chassis” connection position driving pleasure “, and make the operation precision ride comfort highly balanced generation of high performance lightweight chassis, by using the new vehicle in front bracket and developed multi-link rear suspension, also have the dual advantage of high rigidity and weight reduction (weight loss 14 percent). adjustment of the suspension , steering function assigned each member to enhance the comfort of flexibility, stability and the high speed area in the low speed region-wide region, significantly improve the ride quality.
