ICE WITH DISCONNECTABLE CYLINDERS Russian patent published in 2010 - IPC F02D17/02 

FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises connecting rod gear and valve gear, fuel system, lubrication system and cooling system, transmission shaft 14, its gears 13 and gears 12 of crankshafts 7. Gears 13 are engaged with transmission shaft 14 via free running sleeves 15. Gears 13 of transmission shaft 14 mesh with gears 12 of crankshafts 7. Gears 12 are fitted in symmetry and in pairs on sides of gears 13. Front support 10 of the next crankshaft is the bore 11 in last crankshaft tail part. Gear ratio between gear 12 and gear 13 can make 0.5. Valve gear is driven by transmission shaft gear 18 that drive engine systems. Transmission shaft 14 represents a hollow shaft. ICE disconnected cylinders can be started by hydrodynamic couplings or clutches. In the case of asymmetric arrangement of cylinders, crankshafts 3 are engaged in turns by gears 12 with transmission shaft gears 13.

EFFECT: ICE higher efficiency and longer life.
