Mazda 3 engine is imported?
Mazda 3 Angkeira is a car produced by Changan Mazda Automobile Company. It is the third model with the theme of "Soul Moving" and the new generation of "Chuangchi Blue Sky" technology. 20 14 Beijing auto show started. This model is equipped with "SKYACTIV-G 1.5L" and "SKYACTIV" two Chuangchi Blue Sky gasoline engines with high efficiency.
Chuangchi Blue Sky Technology was put forward by Mazda Motor Company of Japan in June 20 10, and it is planned to optimize the main parts of its vehicles such as gasoline and diesel engines, automatic manual transmission, chassis and body structure before 20 15.
Extended data:
Increase torque in low and medium speed range. Theoretically, if the compression ratio is increased from 10.0 to 15.0, the combustion efficiency can be improved by about 9%, but high compression ratio will raise the temperature near the top dead center of the compression stroke, cause knocking and reduce the engine output power.
Therefore, this technology can achieve high compression ratio by reducing the residual gas in the combustion chamber. Its main technology is: 4-2- 1 long-path exhaust system: Take an in-line four-cylinder engine as an example, if the exhaust path is too short, the high-pressure exhaust pressure wave discharged from the exhaust valve of the third cylinder will enter 1 cylinder that has completed the exhaust stroke and is about to start the intake stroke.
