A modular family of internal combustion engines is described. The family includes at least two engine configurations selected from a single cylinder, V-type, inline, opposed, W-type, and radial configurations. Each of the engines in the family includes at least one cylinder with identical top end packages. A method for designing such a family of engines is also disclosed.

Motor engine family

A combined flame arrester and intercooler for cooling intake gas for an internal combustion engine is disclosed. The intercooler comprises an elongated body having a longitudinal axis. The elongated body has a central passageway that extends substantially parallel to the longitudinal axis. An inlet opening is located on one end of the elongated body such that the intake gas enters the central passageway though the inlet opening. The intercooler further includes a plurality of cooling tubes forming at least a portion of the elongated body. The plurality of tubes substantially surround the central passageway. Each of the cooling tubes is spaced from an adjacent cooling tube such that an air flow path is formed there between. The intake gas is cooled by flowing past the cooling tubes. Preferably, the intake gas flows along the central passageway in the elongated body and radially outward therefrom through the air flow path between the cooling tubes. The intercooler includes at least one plate extending substantially orthogonal to the longitudinal axis. Each plate includes a central opening therein, which corresponds to the central passageway in the elongated body such that the intake gas is capable of flowing through the central opening. Each plate has a plurality of openings formed thereon about a periphery of the plate. One cooling tube is fed through each opening.

A modular family of internal combustion engines is described. The family includes at least three engine configurations selected from a single cylinder, V-type, inline, opposed, W-type, and radial configurations. Each of the engines in the family includes at least one cylinder with identical top end packages. A method for designing such a family of engines is also disclosed. A family of recreational vehicles and method for designing a family of recreational vehicles is also disclosed.

Modular engine family

The four stroke internal engine having an air intake system connected to the cylinder head and operatively connected to the intake passageway. The air intake system includes an air intake manifold having symmetrical construction with a central air passageway extending between a first end and a second end. At least one passageway extends from the central air passageway to a free end, which is operatively coupled to the intake passageway. The air intake system is usable for both a supercharged and normally aspirated engines.
