As part of its future plans, Mazda has announced that it will be introducing a new generation of petrol engines that are cleaner than electric cars. To be more accurate, these engines are said to be cleaner from a ‘well-to-wheel’ point of view – which measures emissions over the car’s entire life cycle, including the fuel it uses.
To be dubbed Skyactiv-X, these engine s use compression ignition technology, in which the fuel-air mixture ignites spontaneously when compressed by the piston, just like in the diesel engines. However, the good-old spark plugs are still present and they are there to mix petrol and air together in the cylinder, with the mixture then ignited either via compression at a lower load or via spark at higher loads.
Thanks to all these new tech, the new petrol engine is around 20 to 30 percent more fuel efficient over the current Skyactiv-G of the same size. In fact, the new engines may even have better fuel economy figures than its Skyactiv-D diesel engine!
Set to be launched in the market in 2019, these engines will also come fitted with a supercharger to squeeze out 10 to 30 percent more torque when compared to today’s Skyactiv-G engines.
