    • Gasoline and Diesel combustion compared to Mazda Skyactiv-X SPCCI which combines aspects from both

      This is a very cool video comparison by Mazda that gets right to the point. You should already know how fuel combusts in traditional gasoline and diesel internal combustion engines. If not, Mazda offers a great and simple overview here.


      They then toss into the mix their Skyactiv-X SPCCI technology which combines aspects from both. What is SPCCI? It stands for Spark Controlled Compression Ignition.

      Why is this a big deal? Skyactiv-X will be the first production gasoline motor with compression ignition. This means a leaner mixture and in theory efficiency gains. The motor should be fairly high compression as well.

      Mazda claims superior performance in addition to efficiency. The high compression should also improve response.

      So far Mazda only showed a four-cylinder supercharged prototype so it remains to be seen which models get this technology and what the engine configuration can be.

      Will it catch on or offer anything to the performance community? Time will tell.
