ABSTRACT:
A variable displacement internal combustion engine having a series of at least three cylinders, each having a piston attached to a connecting rod which drives a crankshaft which is common to the three cylinders, wherein the cylinders include a first cylinder, a second cylinder having about twice the capacity of the first cylinder, and a third cylinder having about twice the capacity of the second cylinder, and in which each cylinder may be independently deactivated to allow selected cylinders to operate in an idle mode, whereby the power output of the engine may be widely varied. Preferably, the engine has its cylinders arranged in opposed pairs of first, second, and third cylinders, and also has a pair of fourth cylinders which are each twice the capacity of each third cylinder.
