Mazda will develop the most efficient petrol engine

They are equipped with machines will be cleaner than electric cars

More and more car companies begin to boost development of electric cars. Many believe that in 10-20 years cars with internal combustion engines will be banned in Europe and China. Because of this investment in the design of the internal combustion engine of the next generation are reduced because the development cycle extended over several years, there is a high probability that the money spent is simply not kicking due to serial production. But Mazda keeps an optimistic attitude. She revealed some of the features of the Skyactiv engines of the third generation.

First powertrain Skyactiv-G was introduced in 2011. Mazda announced a record high for gasoline engine compression ratio 14:1 and low fuel consumption. In 2019 to begin deliveries of cars with Skyactiv-X — the second generation of these motors. They will learn how to partially do without spark technology ignition homogeneous charge compression (Homogenous Charge Compression Ignition). And now the company's engineers decided to look into the more distant future. We are talking about the Skyactiv-3.

According to Mitsuo Hitomi (Hitomi Mitsuo), Executive Director for Mazda power units, when creating the third generation of petrol engines Skyactiv will focus on improving thermal efficiency. This ratio indicates what proportion of all allocated during the ignition of the fuel energy goes directly to the cause. For example, modern series motors into striking lamps have an efficiency level of 27 %. In the Skyactiv-3 this parameter will be increased to 56 %.

In fact, while none of the ice in the world can demonstrate such a high efficiency. One of the Champions last fall, was the engine Mercedes-AMGthat came out at efficiency of 50 %. But then it was the engine for "Formula 1", and this rate was still only on a chassis dynamometer, not during the actual races.

According to the calculations Mitsuo Hitomi, so perfect the motor allows the gasoline car to become cleaner electric. In this case means that even with the fuel-burning car with a Skyactiv-3 will produce less carbon dioxide than will be disposed power plant, producing energy for charging electric vehicles. In addition, carbon dioxide emissions will be reduced by 25 %.

There is no accurate information about when the engines Skyactiv-3 will start to install on a serial machine. It is likely that this will happen only after 8-10 years.
