USA announced to Autoblog that the company is still working on the 16X rotary engine, and it will debut in a a yet-undisclosed new car in two years according to current plans. 

The 16X is Mazda's next generation rotary engine that is based on the Renesis rotary. Mazda says that it has more torque, more power and lower weight than the Renesis. It also has better emissions and fuel economy, which have been major problems with the rotary engine's design.

An inherement portion of the rotary engine's design is that oil is injected into the combustion chamber to lubricate the rotor. The burning oil has an extremely detrimetal effect on emissions. Mazda says that it has found ways to decrease this problem.

"The key to both higher torque and better fuel consumption is creating a longer stroke engine. By the path of travel within the combustion space dictated by the engineers," said the insider.

The 16X has 1.6-liters of displacement instead of the 1.3-liters from the Renesis and previous Mazda 13B rotary. Mazda says that it gives the engine greater torque and thermal efficiency. 

Direct injection is used because of the cooling effect that the atomized fuel has on the rotor. It reduces temperatures and also increases fuel economy.
