Claim:
A V-type engine, comprising: a crankshaft with a longitudinal axis; two cylinder banks, each of which comprises two cylinders with respective longitudinal axes that are oriented to form a “V” in a plane that is perpendicular to the longitudinal axis of the crankshaft, and each of which cylinders contains a piston that is moveable in a reciprocating manner in the cylinder and that is connected by a connecting rod to the crankshaft, and further where the longitudinal axis of one of the cylinders in one of the cylinder banks is in a common plane with the longitudinal axis of the crankshaft and with the longitudinal axis of one of the cylinders in the other cylinder bank; and a firing system which causes fuel to ignite simultaneously in the cylinders in which the respective longitudinal axes are co-planar with each other and with the longitudinal axis of the crankshaft.
