Technological risk

The FP3 concept is, in essence, a novel, innovative assembly of established, proven technologies. The internal combustion engine with a cylindrical combustion chamber and circular seated valves deviates little from current technology.

The design of the linear electric generator and power electronic control system is similarly orthodox. Recent developments in power electronics components and control technology make a linear generator design incorporated in the FP3 feasible. Developing a ceramic coating methodology for the stator has proven to be pesky but we are confident that we have succeeded in finding a solution.

The application of free pistons in pneumatic and hydraulic energy conversion is well established. A perceived risk in the FP3 design was the sensor-less position control of the mechanically unconstrained pistons. Testing, however, has verified that we are able to obtain the accuracy required with regard to compression ratios, independent of load or misfire, in a combustion chamber.

The technical risks associated with installing the FP3 in a Series HEV we regard similarly as low. The electric traction drive design of the Series HEV is based on our own, proven expertise in this field. Compact, low-mass, unsprung electric wheel motors are becoming more and more mainstream and generally accepted.

Battery technology required for a Series HEV has reached levels of power density and reliability that ensure domination as energy storage device for the foreseeable future.
