Abstract:
One illustrative embodiment includes a turbocharger (16, 18) with a turbine (94) and a compressor (96). The turbine (94) has an inlet passage (114) which may directly communicate with a blowdown exhaust port (34, 36, 38) of a cylinder head (12) of an internal combustion engine (14). The inlet passage (114) may directly receive exhaust gas from the blowdown exhaust port (34, 36, 38).

Abstract:
The invention relates to a cylinder head (10, 30) for a combustion engine that includes an exhaust manifold (11, 31), wherein said cylinder head (10, 30) includes means (17, 37) for securing a combustion gas exhaust duct and a cooling circuit (21, 40) of said exhaust manifold, characterised in that said cooling circuit (21, 40) includes at least one baffle (25, 41, 42) modifying the flow direction of the coolant fluid in order to direct the latter towards the securing means (17, 37). The invention can particularly be used in the field of automobiles.
Abstract:
The invention relates to a cooling system (1) for an internal combustion engine, having a first coolant flow which cools a crankcase of the internal combustion engine, having at least one second coolant flow for cooling at least one cylinder head which is assigned to a cylinder, and having at least one third coolant flow for cooling at least one outlet duct (2) of the cylinder. The second and the third coolant flows are formed from the first coolant flow, and the third coolant flow, after cooling the outlet duct (2), is merged in the cylinder head with the second coolant flow. The invention also relates to an internal combustion engine.
Abstract:
L'invention concerne une culasse (10, 30) d'un moteur à combustion intégrant un collecteur d'échappement (11, 31), ladite culasse (10, 30) comportant un moyen de fixation (17, 37) d'un conduit d'échappement des gaz de combustion et un circuit de refroidissement (21, 40) dudit collecteur d'échappement (11, 31), caractérisée en ce que ledit circuit de refroidissement (21, 40) comporte au moins un déflecteur (25, 41, 42) modifiant la direction de circulation du fluide caloporteur pour le diriger vers ledit moyen de fixation (17, 37) L'invention trouve notamment une application dans le domaine des véhicules automobiles.
Abstract:
In an internal combustion engine, one end of a cylinder head (1) in a longitudinal direction is provided with a cooling water inflow port (19) leading to the inside of the cylinder head (1), while the other end of the cylinder head (1) in the longitudinal direction is provided with an outflow port (20) of main cooling water flow (X) flowing through the center inside the cylinder head (1). Further, an outflow port (21) of sub cooling water flows (Y) branched from the main cooling water flow (X) and flowing around the merged part of the exhaust port (5) is provided. An adapter (23) communicated with the main cooling water outlet (20) and sub cooling water outlet (21) and combining these outflow ports (20, 21) into a single cooling water outlet (22) is fixed to the outer wall surface of the cylinder head (1).
Abstract:
A supercharged four stroke internal combustion engine. The engine includes a power take off housing located on one end of the crankcase. A supercharger for boosting air intake to an air intake manifold is mounted to the power take off and operatively connected to the crankshaft within the power take off housing. A personal watercraft having a supercharged engine is also disclosed.
Abstract:
A four stroke internal combustion engine is disclosed having a lubrication system for circulating lubricant within the engine. The engine further includes a system for separating lubricant from blow-by gas within the crank case.
