Based on the techniques set out above, SPCCI has expanded the zone of compression ignition right into the full throttle range, and enables smooth switching between SPCCI combustion and spark ignition combustion.

To minimize compression time and make compression ignition as efficient as possible, the fuel must be vaporized and atomized very quickly and then immediately dispersed around the whole of the cylinder.

To do this, Mazda has further developed several elementary technologies — a new piston head design and super-high-pressure fuel injection system to support compression ignition, and a high - response air supply which can deliver larger amounts of air — and combined these with an in - cylinder sensor which serves to control the entire engine.

This new combustion method does not merely use spark ignition to assist compression ignition, but delivers an all - encompassing combustion control system which includes control of in - cylinder temperature and pressure and control of the fuel injection's air - fuel mixture distribution density and exhaust gas recirculation (EGR).

According to Autocar, Mazda is developing its homogeneous charge compression ignition technology (HCCI), where the mixture is ignited by compression rather than a spark, similar to a diesel engine.
