Mazda hails more efficient petrol engine
Japanese carmaker Mazda has developed a more efficient petrol engine at a time when the industry steers toward electric vehicles. It said the compression ignition engine was up to 30% more fuel-efficient than its current engines. Last week, Mazda said it would work with Toyota to develop electric vehicle technology and build a $1.6bn plant in the US. Mazda research and development head Kiyoshi Fujiwara said it was imperative for the company to pursue the "Ideal internal combustion engine". Mazda said the Skyactiv-X, as it is known, would be the world's first commercial petrol engine to use compression ignition. According to Mazda, the fuel-air mixture ignites spontaneously when compressed by the piston in the new engine.
