Status quo of the FP3 R&D program
The FP3 project was launched in February 2001. Prototype electronic control and
power modules, sub-systems and internal combustion engine components as well as
associated control software were developed.
We first ran a quarter section spark ignition prototype in October, 2004. Mover
sensor-less position control performed well. Shortcomings in the scavenging process
and linear generator efficiency were identified. Novel, tilted passive intake valves
have been developed which significantly improve scavenging efficiency.
The linear generator has been completely redesigned and optimised. Electrical efficiency
is expected to increase to 95%.
A Diesel head, with central injection and a novel quad exhaust valve with a total
power consumption of less than 300W has been designed and constructed and is currently
undergoing test with promising results.
A means of applying a ceramic coating to the Linear Generator Stator Assembly has
been developed and is currently being applied.
We expect to be able to assemble and test our second-generation, Diesel prototype
by December, 2007.
