Overview of the new Mazda SKYACTIV technology

Mazda SKYACTIV-G to achieve the world's highest compression ratio and efficient direct-injection gasoline engine.

The new generation of high-performance gasoline direct injection engine, the compression ratio of 14.0:1, hit a new record high gasoline production engine, fuel consumption and torque can be increased by 15%, and other unique 4-2-1 exhaust Tau, the special design of the piston at the top, high-pressure fuel injectors.

SKYACTIV-G technology topics tackled high abnormal combustion engine compression ratio is a world's highest compression ratio (14.0:1), a new generation of high-performance direct-injection gasoline engine.

1, as a production car equipped with gasoline engines, the first time in the world 14.0:1 high compression ratio;

Significantly enhance the combustion efficiency of the engine through the high compression combustion, fuel economy and torque are improved by 15%;

3, through the enhancement of the low-speed torque, in the field of practical driving improve the convenience of use;

4, using a concave top piston, the porous nozzle innovative technologies to achieve high compression ratio of 4-2-1 exhaust system.

* Compression ratio and the use of technology in accordance with the fuel specifications and equipped models vary.
Mazda SKYACTIV-D diesel engine.

Mazda SKYACTIV-D technology to achieve the global maximum compression ratio (14.0), and does not use urea SCR catalyst, the expensive nitrogen oxides of the NOx adsorbing catalyst (LNT) the conditions of the post-processing apparatus, beyond the global emissions predetermined generation clean. diesel engines.

1, through the low compression ratio (14.0) so that fuel economy is improved by about 20%;

2, through the use of dual-stage turbocharger, so that the vehicle smoothly from low speed to high-speed linear reaction, and a substantial increase in the torque of the low speed region and the high speed region (the maximum number of revolutions: 5200rpm);

3, under the conditions of the post-processing equipment does not use expensive nitrogen oxides to achieve high environmental performance beyond global emissions regulations (Europe: Euro6 North America: Tier2Bin5, Japan: Post a new long-term provisions)...
