Abstract:
A generation change in crank mechanisms (CM) is taking place in the entire world. The author has been performing research and development (R&D) work on novel magneto-rheological fluid (MRF) mechatronic commutator, reciprocating, piston-type internal combus-tion engines, that is, 2-, 4- or even 5-stroke thermodynamic cycle, twin-opposed piston, crankless ICEs called the Fijalkowski engines (FE) for over twenty years. For vehicular appli-cations, especially for hybrid-electric vehicles (HEV), a high thermal efficiency is important for good liquid-fuel economy, but it is also important that the power plant be simple and com-pact. A preliminary design optimisation study resulted in a novel MRF reciprocating, four-stroke thermodynamic cycle crankless ICE concept with a relatively high thermal efficiency.
This crankless ICE has not generally been favoured for HEV applications in the past, but use of a direct coupled automotive silent 'four-in-one' flywheel/damper mechano-electrical (M-E) generator/electro-mechanical (E-M) motor, with macro- and microelectronic control of elec-trical energy transmission makes the constant ICE's output driveshaft angular velocity run-ning feasible, maintaining near-optimum ICE conditions over a wide power range.
   
Key Words: crank mechanism (CM), electro-rheological fluid (ERF), magneto-rheological fluid (MRF), hybrid-electric vehicle (HEV), internal combustion engine (ICE), mechano-electrical (M-E) generator, electro-mechanical (E-M) motor.
