It's worth adding that this kind of design is not new. According to 
Wikipedia "In 1911 the Macomber Rotary Engine Company of Los Angeles 
marketed one of the first axial internal-combustion engines" of a similar 
design. The question is why they never really caught on and I've read just 
recently that the major problem with this design (swash or wobble plate 
engine) is not with cooling or lubrication but the amount of torque that the 
plate can withstand and transfer. For that exact reason this design has been 
adopted in A/C compressors. It works much better when the shaft is driven 
pushing the pistons and compressing a gas than the other way around. In 
short, it makes a great pump but not so great engine.

This engine design was a extension of the “swash plate” design in air 
conditioning compressors.
The main challenges in this design are cooling and the amount of pressure 
the plate could handle and convert into rotational torque.

This concept works well with total submersion in AC coolant and the little 
torque necessary for compressing a gas, but
the forces for moving a car and orders of magnitude larger.
