Abstract (en)

[origin: WO0134954A1] An internal combustion engine having a power cylinder (200), whereby the power, ventilation (comprising simultaneous intake and exhaust), and compression events within the power cylinder (200) completed define the cycle of the engine, with induction in the induction cylinder (100) being an auxiliary and incidental function to the cycle within the power cylinder (200), such that engine cooling and fuel efficiency are improved over prior art internal combustion engines. Interconnecting the power cylinder and the induction cylinder (100) is a transfer chamber which opens into the top of the power cylinder (200), which chamber in turn is equipped with a one way, pressure responsive transfer valve (60) for allowing air to flow into the power cylinder (200) when pressure therein falls below the pressure in the induction cylinder (100). An exhaust port (12) is likewise positioned near the bottom of the power cylinder (200).
