Advance IC Engine

The main areas of advancements were in the engine design, the timing controls, fuel injection, combustion and material selection [1]. With the recent technological advancements, the current engine designs are fuel efficient, and produce much fewer emissions.

The linear generator is designed such that electricity is generated directly from the pistonís oscillating motion, as rare earth permanent magnets fixed to the piston are driven back and forth through the alternatorís coils. Combustion occurs alternately at each end of the piston and a modern two-stroke cycle scavenging process is used. The alternator component controls the pistonís motion, and thus the extent of cylinder gas compression, by efficiently managing the pistonís kinetic energy through each stroke. Compression of the fuel/air mixture is achieved inertially and as a result, a mechanically simple, variable compression ratio design is possible with sophisticated electronic control.
