Mazda really ought to be appreciated for not mindlessly following the hybridization trend , choosing instead to perfect the art of building a traditional , conventional car via its Skyactiv program .
Now , AutoNews Tells us that the Japanese manufacturer will continue to go in the same direction in the future , and that by the year 2020, the Skyactiv 2 will have made its debut on the market , with efficiency improvements in the order of thirty percent Compared to what we have now .
The way in the which they plan to Achieve this is via complete and clean burn of the ( diesel or gasoline ) fuel so that the engine is both more efficient and less polluting .
According to Mitsuo Hitomi , the executive officer in charge of powertrain development at Mazda , " If we want to dramatically improve fuel economy from here , the only route is through lean burning , " adding that "the next step is the 2020 European regulations " ( 95 g / km CO2 ).
One specific way through the which the automaker aims to Achieve its goals for gasoline engines is by raising the compression ratio , something that it has already done with the current crop of SKYACTIV motors that run at 14:1 ( very high Compared to industry average) - apparently they want to raise that to 18:1 .
Aside from that , they also want to employ what is called HCCI or homogeneous charge compression ignition , the which uses pressure to ignite the fuel / air mixture , instead of a traditional spark - it would burn petrol yet function along the same lines as diesel engines , basically .
The current problem with HCCI engines is that running in that way do not really like to rev , mimicking the behavior of a diesel . This must be Overcome , along with higher operating Temperatures and pressures that will put extra strain on the entire system , require higher strength parts and ultimately end up being too expensive to be viable en masse .
Following the second gen Skyactiv will be Skyactiv 3 , in the year 2025. The goal will be further lowering emissions to 65 g / km of CO2 , and bringing in a proportional increase of efficiency too.
