When it comes to Mazda's Chuangchi Blue Sky technology, many people's first impression is Chuangchi Blue Sky Engine, in fact, Chuangchi Blue Sky Technology includes gasoline and diesel engines, manual and automatic transmissions, chassis, body structure technology, but the engine is indeed the most intuitive embodiment of Chuangchi Blue Sky technology.
Although the parameters are not eye-catching, Mazda's Chuangchi Blue Sky Engine, only those who have driven it understand its good. So, what is so good about the Mazda Chuangchi Blue Sky engine? Does a high compression ratio affect engine life?
Chuangchi Blue Sky engine has 1.5L, 2.0L, 2.5L three displacements, and the pursuit of power parameters, like high-pressure direct injection of European and American turbocharged engines different, Mazda still adhere to the self-priming engine, and the self-priming engine to the extreme, with a number of original technologies.
1. Ultra-high compression ratio
Most of the family cars, the compression ratio generally does not exceed 11:1, some performance cars can exceed 12:1, but Mazda's Chuang chi blue sky engine the highest compression ratio of up to 14:1, after the introduction of the domestic because of the oil problem control at 13:1, but also much higher than the friendly business.
One of the most critical technologies is that Mazda's Chuangchi Blue Sky engine adopts two internal combustion engine thermal cycle modes, under high load conditions, the use of Otto cycle with a compression ratio of 13:1, other working areas are more fuel efficient, compression ratio of 10.5:1 Miller cycle, not only adapt to domestic oil products, but also achieve the effect of improving fuel economy.
2. 4-2-1 exhaust system
However, the high compression ratio engine is easy to produce knock phenomenon, causing irreversible damage to the engine, so Mazda redesigned the exhaust system, using a 4-2-1 exhaust system, which is equivalent to converging the exhaust gas from four to two, and then intersecting to an exhaust pipe, the length of the exhaust is greatly increased, the exhaust gas residue is reduced, and the probability of detonation is greatly reduced.
3. Ultra high pressure injection + concave top piston
In addition to solving the exhaust problem, Mazda Chuangchi Blue Sky adopts ultra-high pressure 6-hole in-cylinder direct injection technology, multi-point launch, ultra-high speed, and accurately hit the target. In order to inject more accurately, Mazda also dug a hole in the middle of the piston, and the gasoline was accurately injected into the hole, reducing the concentration of gas at the far end of the cylinder, facilitating the more uniform combustion of the gas mixture and reducing knocking.
The above technology makes the Chuangchi Blue Sky engine not only save fuel, but also well inhibits the generation of knocking, and does not have to worry about the ultra-high compression ratio will cause the engine life to decline. Since the launch of Chuangchi Blue Sky Technology in 2010, it has been 10 years now, and in the past ten years, Mazda's engine has not had too many quality problems, and the overall reliability is remarkable. Moreover, most of the domestic cars are not driven to scrap, but are forced to scrap by emission regulations and restriction policies, so instead of worrying about engine life, in fact, you should pay more attention to emission regulations.
