Whether you are interested in reducing the environment impact of your life or simply looking to tighten the purse strings in these challenging economic time, fuel efficiency is at the forefront of most people’s plans. You may use your vehicle for a daily commute, or simply rely on it for everyday life, but there is no need to explore the strange new developments offered by some car developers, when Mazda can assist you with fuel efficient models like the Mazda CX5.
Mazda has been a popular choice of new vehicle in the Australian marketplace for a great many years. However, one of the main reasons why Mazda is topping the sales charts for the last few years, is thanks to their continued development of improving the internal combustion engine. While many car manufacturers have directed resources into the exploration of possible alternative fuels such as hydrogen, Mazda has been busy perfecting the SkyActiv engine.
According to industry research and recent reports, the second generation model of the SkyActiv engine could be up to thirty percent more fuel efficient than the existing models. Considering the existing SkyActiv engine range currently offers very low fuel consumption rates, this is a bold move from the Japanese car giant.
For example, the current Mazda CX5 using a two litre petrol SkyActiv engine can provide a fantastic consumption of 6.4 litres per 100 kilometres using a combined cycle. Similarly, the Mazda 6 with a 2.5 litre petrol SkyActiv engine offers 100 kilometres for only 6.6 litres of fuel. The diesel SkyActiv range is even more fuel thrifty, with the 2.2 litre SkyActiv D turbo in the Mazda 6 offering 100 kilometres for only 5.4 litres.
If the proposed fuel economy changes are successfully accomplished by Mazda, this could mean a thirty percent fuel saving, with a petrol engine SUV managing average fuel economy of just 4 litres per 100 kilometres. Diesels would fare even better with a Mazda 6 diesel achieving 3.5 litre consumption per 100 kilometres.
So, is this achievable? According to Mitsuo Hitomi from Mazda, the refinements the company are planning to make to the combustion processes will achieve these results. Hitomi has been quoted as saying that the only way to dramatically improve fuel efficiency is “through lean burning”.
Lean burning would mean reducing the amount of fuel which is injected into the cylinders per specific amount of air. This technique is capable of producing increased power using smaller amounts of fuel but it does require the engine to be carefully tuned to avoid harmful gas emissions and issues with engine longevity.
Additionally, increasing the compression ratio can also boost the torque and power without compromising fuel economy. Mazda have reportedly made plans to increase the compression ratio on the SkyActiv petrol engine models from 14:1 to an amazing 18:1. This would provide fantastic results without resulting to a turbocharger.
The proposed timeline for the second generation SkyActiv range has not yet been announced but many believe that newer technologies will be needed when the new emissions legislation is mandated in Europe for 2020.
