With the Japanese Toyota, Honda and Nissan compared to the three brothers, Mazda in the market to maintain a relatively low level, because Mazda to put more energy into the nature of the repairer, it has been known as the outside world Car technology car prices. Mazda's pursuit of the engine technology is never tired, each of its models are almost inseparable from the movement of the word, and the adjustment out of the vehicle control is absolutely first class, but appreciate the Mazda technology inherent in the consumer is not too much. When the rotor engine was abandoned, only Mazda is still studying with great concentration, Mazda is the world's first rotor engine mass production of the car business, had to admire Mazda technical paranoia. Natural inspiration has always been synonymous with Japanese cars, but now adhere to the coilovers natural way of breathing only Mazda, Mazda engineers believe that the natural suction engine there is room for improvement, Chu-blue technology is "deep digging" result. Mazda in the automotive technology investment can be said to be more than marketing, as the industry said that other man-made cars in order to make money, Mazda is to make money. Toyota and Mazda cross-holding 5% of the new power system cooperation and sharing agreement has been used by the outside world. Among the Japanese companies, Mazda and Honda are focusing on technical research, Toyota is more focused on the scale of efficiency. Japanese car prices in the global giants which are more alternative, each car prices are very insistent on the style of self, Toyota as a car driver of course, will not easily cooperate with the younger brother, this cooperation with Mazda to share power technology, is undoubtedly a fancy Mazda The second generation of Chi-blue technology can give their own hybrid to bring substantial help, there is still a need to explain what is the creation of blue sky technology. SKYACTIVTechnology (SKYACTIVTechnology) is not the name of a car technology, the first proposed by the Mazda in October 2010, plans in 2015 for its models of gasoline and diesel engine, manual transmission and automatic transmission, chassis , The body structure and other major components to optimize the technology in general (due to the creation of blue sky technology contains too much content, this article only describes the Chi-blue sky engine). The first generation of Chi-blue sky in June 2011 by the mass production, Mazda CX-5 became the first production models. The first generation of Chi-blue technology will gasoline engine compression ratio increased to 14: 1, fuel economy and power performance increased by 15% or more in the industry a sensation. The first generation of Chi-blue sky has been so strong, and Mazda's craftsman spirit exposed, 2015 Mazda began the second generation of Chi-blue sky technology, and this is a direct attracted to the eyes of Toyota. Design of Black Technology for Generation of Hitachi Blue Sky Engine For the piston-type internal combustion engine, to improve the compression ratio is one of the most effective way to improve engine efficiency, the first generation of Chi-blue engine will increase the compression ratio to 14: 1, and most of the passenger car compression ratio can only be achieved 9: 1-11: 1. Although the high compression ratio in exchange for high performance and low fuel consumption, but also often lead to burst cylinder, reduce the efficiency of the engine Redesign the exhaust system. Mazda engineers designed a 4-2-1 exhaust system, which first merges four separate exhaust manifolds into two exhaust manifolds and then aggregates them into an exhaust manifold. On the one hand to increase the length of the exhaust pipe, on the other hand the ignition time adjacent to the two trachea separated, basically able to reduce the amount of exhaust gas in the full range, so as to prevent the occurrence of knock. Porous nozzle, concave piston to improve the cylinder combustion environment. The use of high-pressure jet of the nozzle, to improve the spray characteristics, the formation of a more homogeneous mixture, but also a corresponding reduction in the formation of mixed gas. In addition, the use of concave top piston (the top of the piston is designed as a concave hole), you can form a thick mixture around the spark plug, even if the ignition time can be maintained to maintain stable combustion performance. The structure is lightweight and reduces internal energy loss. The Chiming Blue Sky Gasoline adjustable coilovers Engine reduces the mechanical resistance by 50% through the improvement of the valve transmission mechanism, while reducing the piston ring tension to reduce the mechanical resistance by 37%, resulting in a 30% reduction in overall mechanical resistance of the engine. The piston and piston pin weight reduction of 20%, connecting rod shaft weight loss of 15%, the crankshaft main shaft weight loss of 6-8%, in order to reduce the movement of the piston parts, Final engine weight loss of 10%. Two cycles of dual mode switching. Here to add that point is to adapt to the actual situation of Chinese oil, domestic Mazda Chi Chi blue sky engine can not achieve 14: 1 compression ratio, but the application of the 13: 1 compression ratio, which can not be in the whole situation Keep under. In order to solve this problem, Mazda Chuang blue sky engine with a Miller cycle and Otto cycle dual mode switching mode, when the engine into the high load conditions, the engine will switch to a compression ratio of 13: 1 Otto cycle , And when the engine is in a partial load condition, the engine will only operate in the Miller cycle mode. HCCI (homogeneous pressure burning) technology to help create a blue sky and then upgrade HCCI is HomogeneousChargeCompressionIgnition abbreviation, translation is homogeneous mixed gas compression technology, the core of this technology is homogeneous mixed gas (HC) and compression (CI). The new generation of Chi-blue engine with HCCI technology, can make gasoline, air and exhaust gas mixture in the combustion chamber evenly distributed, and through two ways to ignite. In the high-speed range, HCCI canceled the spark plug ignition, to burn, this work is similar to the diesel engine, but in the low-speed range and the use of the traditional spark plug ignition, HCCI is the two fusion. However, compared to the average engine, HCCI engine mix more fully burned, not simply rely on flame propagation, air and waste gas to reduce the combustion temperature, less heat loss, but also reduce emissions, while enhancing power and fuel economy. However, HCCI technology in the compression conditions and spark plug ignition conditions of the two conditions of choice and convergence is an industry recognized technical problems, but this point by Mazda engineers to develop the spark ignition control compression technology (SPCCI) To solve, the successful realization of the spark plug Turbocharger ignition and ignition between the seamless switch, that is, so that the ignition ignition can be completely controlled. "I-stop" and "Chong Chi blue sky" engine with the use of fuel to achieve more full use. "I-stop" is developed independently by Mazda, and the general "Stop & Start" engine start and stop system is the biggest difference is that "i-stop" is not relying on electric starter to restart the engine, but the world's first use of pre-control piston Stop position of the electronic control technology, in the initial phase of the engine re-ignition that is fueled by fuel injection to restart the engine energy-saving technology. A new generation of Chi-blue sky to bring the data to enhance In the first generation of Chi-blue engine on the basis of the addition of HCCI technology, which makes Mazda in the natural aspiration engine field of data to achieve the possibility. In the second generation of Chi-blue plan announced when the Mazda proposed to be the second generation of Chi-day blue sky engine compression ratio mentioned 18: 1, and the first is expected to be carried in 2018 launched Mazda 6 or Mazda 3 models , While the conventional 1.5L models of 100 km fuel consumption is only 3.3L, which in 2019 to be fully popular in 2020, the engine fuel efficiency of 50%. So that is not intuitive, we can compare some of the data can be aware of the second generation of Chi-day blue sky engine of the powerful. First, the compression ratio of the engine can reach 18: 1, we look at some other models of compression ratio: Jeep free light 2.4L engine compression ratio of 10: 1, Toyota Corolla 1.6L engine compression ratio of 10.2: 1, Volkswagen Second generation 2.0LEA888 engine compression ratio of 10.5: 1, while the Ferrari 458 compression ratio is only 12.5: 1, only more metamorphosis Ferrari 458Speciale only reached with Mazda Chu Chi blue sky the first generation of 14: 1 compression ratio. The second generation of Chi-day blue sky engine fuel consumption compared with the first generation will drop Coilover Shocks 30%. According to reports, 1.5L of the second generation of Chi-blue engine can be used 1L oil driving 30 km, 100 km fuel consumption 3.3L, which is much lower than the vast majority of hybrid fuel consumption. Power also has a great boost, the new generation of 2.0L engine maximum power reached 170 horsepower, will be able to go beyond the public 1.4T EA211 parameters, also very close to 1.8T EA888. While the second generation of 2.5L engine power maximum power reached 210 horsepower, the maximum torque also have different degrees of improvement. The second generation of Chi-day blue sky engine thermal efficiency of 50%. Thermal efficiency refers to the ratio of the heat converted to mechanical work in the engine to the amount of heat consumed. At present, the automotive industry's most efficient engine is the use of Athen Sen cycle Toyota 2.5L engine, the thermal efficiency of 41%, and most of the gasoline engine thermal efficiency is still more than 30% wandering. to sum up: Mazda Chuchuang blue sky father who saw the gentleman has been less optimistic about the turbo, and he also said that will adhere to the natural aspiration engine research. From the rotor engine to the creation of blue sky technology, we can see the Mazda engineers are persistent pursuit of technology, it is their paranoid so that we have reason to believe that the goal of a blue sky technology will also be achieved, then naturally inhale and Turbulence between the contest will rise to a new height.
