Abstract: In a gas engine 1 that uses a gas having a lower specific gravity than air and has a pre-mixing device before a turbocharger, a pre-mixed gas mixture compressed by a turbocharger 3 is cooled by an intercooler 4 located downstream of the turbocharger 3 in the intake system. Condensed water produced as the gas is cooled and the pre-mixed gas mixture discharged with the condensed water are separated into condensed water, air, and fuel gas in a vapor-liquid separator 7. The fuel gas is returned to the intake system upstream of the turbocharger 3, while the condensed water is discharged to atmosphere.

Abstract: A rotatable drive shaft in the swash pump or turbine for liquids is supported by one bearing at each end. An integrated motor or dynamo uses the same two bearings. The compound first bearing supports a slanted section of the drive shaft placed inside the inner swash sphere, and transfers rotational power to the attached nutatable swash plate. The second bearing confines rotation of the drive shaft in a defined axis. Either one of the bearings is made to prevent axial movement of the drive shaft, preventing swash pump misalignment. A resilient drive, and an immersed pump are described.
