  • Patent number: 10364733
    Abstract: An internal combustion engine includes a manifold channel. With respect to a longest cylinder that is a cylinder whose flow channel length from the cylinder to a collective portion is the longest among three cylinders, the manifold channel is provided with a hollow layer that covers a part of a channel wall in the flow channel direction of a branch channel connected to the longest cylinder. With respect to a shortest cylinder that is a cylinder whose flow channel length from the cylinder to the collective portion are the shortest, the manifold channel is not provided with a hollow layer that covers a channel wall of a branch channel connected to the shortest cylinder. A wall that forms the hollow layer for the longest cylinder is formed integrally and continuously with the same material as a channel wall of the branch channel connected to the longest cylinder.

  • Patent number: 10323563
    Abstract: A configuration for a uniflow-scavenged, opposed-piston engine reduces exhaust cross-talk caused by mass flow between cylinders resulting from one cylinder having an open exhaust port during scavenging and/or charging while an adjacent cylinder is undergoing blowdown. Some configurations include a wall or other barrier feature between cylinders that are adjacent to each other and fire one after the other. Additionally, or alternatively, some engine configurations include cylinders with intake and exhaust ports sized so that there is an overlap in crank angle of two or more cylinders having open exhaust ports of about 65 crank angle degrees or less.

  • Patent number: 8650864
    Abstract: An exhaust system for a marine engine comprising liquid-cooled manifold and catalytic converter assemblies. Each assembly uses a separate cooling system to cool either the exhaust manifold or a shell inside which resides the catalytic converter. The housing or shell containing the catalytic converter uses water to cool an exterior surface of a water jacket to an acceptable temperature conforming to federal regulations. The liquid-cooled manifold assembly may use either water or glycol to cool outer cooling tubes surrounding exhaust tubes extending from the engine block to the catalytic converter assembly.
