Abstract: A fuel injection controller for an internal combustion engine selects as the injection mode either single injection or split injection, counts, based on a drive current detection signal, which indicates that a drive current is generated to be fed to the direct injector, the number of occurrences of the drive current in one combustion cycle as a number-of-injections count value, and determines, based on the number-of-injections count value, whether the combustion state in the cylinder is satisfactory. The fuel injection controller determines that the combustion state in the cylinder is unsatisfactory if the number-of-injections count value in one combustion cycle is one when catalyst warm-up control is being performed with the temperature of the engine being lower than or equal to a predetermined temperature.

Abstract: An exhaust system for a marine exhaust system includes two identical liquid-cooled exhaust manifolds. Each exhaust manifold has an outlet portion adapted to receive and retain a catalytic converter. Liquid cooled first and second risers are secured to the first and second exhaust manifolds. Bypass hoses enable fluid to pass from each exhaust manifold to its coupled riser. At the outlet of each riser, the cooling fluid and exhaust gas mix in a Y-pipe to create a combined flow. An exhaust outlet conduit downstream of the Y-pipe receives the combined flow and discharges the combined flow.

Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, a method may include decreasing gas flow from the first exhaust manifold to the intake passage, upstream of a compressor, where a first set of exhaust valves are exclusively coupled to the first exhaust manifold, in response to a condition of the compressor. Further, the method may include increasing gas flow from the first exhaust manifold to an exhaust passage coupled to a second exhaust manifold coupled to a second set of exhaust valves, in response to the decreasing gas flow.

Abstract: Methods and systems are provided for maintaining a desired engine coolant level and a relative glycol amount in the engine coolant by using water sourced from on-board vehicle systems. In one example, a method may include supplying water to the engine coolant reservoir in response to the engine coolant level decreasing below a threshold. Also, a relative glycol amount in the coolant may be maintained at a threshold amount by adding water to the coolant in response to a relative glycol increasing above the threshold.

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.
