Abstract:
An aftercooler thermostat housing for an engine is disclosed. The housing system comprises a housing and a thermostat within the housing. The housing system further includes a bypass system for providing a connection to allow an engine coolant to flow to the aftercooler system if the engine coolant temperature is below a first predetermined temperature. The bypass system allows for the engine coolant to flow through a heat exchanger which is part of the aftercooler system if the temperature of the coolant is above the first predetermined temperature. A low temperature aftercooler (LTA) thermostat housing system achieves the necessary heat rejection for the engine via the heat exchanger and achieves low temperature aftercooling using the heat exchanger.

Abstract:
In an outboard engine system, an exhaust manifold fixed to a cylinder head of a vertical engine by a bolt includes single pipe portions and a collecting portion through which an exhaust gas flow. A water jacket, through which cooling water flows, is formed to surround a periphery of the collecting portion. An exhaust characteristics sensor for detecting an oxygen content of exhaust gas is mounted to an upper surface of the exhaust manifold. A water temperature sensor for detecting temperature of the cooling water is mounted to a side surface of the exhaust manifold.
Abstract:
A cooled valve seat ring for a cylinder head of an internal combustion engine, having a valve seat part, wherein the cooled valve seat ring comprises a sheet-metal cooling channel consisting of a thin sheet of steel and which is connected with a coolant circuit via bores which serve as inflow and outflow for a coolant, wherein the cooled valve seat ring is connected with the cylinder head material by casting technology. In one embodiment, there can be a cooled valve seat ring that is connected with a cylinder head material via a laminate casting process. There can also be a cooled valve seat ring that has an alfin layer for a connection with the cylinder head material. In addition, the cooling channel can be welded onto or soldered onto the valve seat part. Furthermore, the sheet-metal cooling channel can be connected with the valve seat part so as to form a gas-tight seal.
Abstract:
An open-looped cooling system is disclosed. The cooling system typically includes a cylinder head including a first water jacket through which cooling water flows, a cooling water inlet through which the first water jacket communicates with outside, and a first cooling water outlet through which the first water jacket communicates with outside, a cylinder block including a second water jacket through which the cooling water within the first water jacket flows, the second water jacket being configured to communicate with the first water jacket, and a second cooling water outlet through which the second water jacket communicates with outside, and a thermostat configured to control a flow rate of the cooling water flowing out from the second cooling water outlet of the cylinder block based on a temperature of the cooling water.
Abstract:
A snow vehicle which is capable of increasing the cooling efficiency of an intercooler thereof by reducing the influence of intense heat from a supercharger thereof, while suppressing the overall height of an engine thereof. An engine hood covers a front part of the body frame from above, and an engine room is formed under the engine hood. A supercharger is disposed in the engine room at a location forward of the engine, and an intercooler is disposed rightwardly of the engine. High-temperature air from the supercharger is cooled by the intercooler and supplied to the engine. An air inlet port is formed through a front left half of the engine hood, for taking in air for cooling the supercharger etc., and another air inlet port is formed through a front right half of the engine hood separately from the air inlet port, for taking in air for cooling mainly the intercooler and a battery.
Abstract:
Engine (101) of an amphibious vehicle (100) is located in engine compartment (102). The engine is cooled by radiator(s) (103), mounted in cooling compartment (104), which is separate to compartment (102), and may be sealed off therefrom. Ram air effect or fans (105) (driven electrically, hydraulically, or mechanically) may be used to draw cooling air into compartment (104) through radiator (103), and out past exhaust silencer(s) (107) through opening (106). Coolant hoses (109) and exhaust pipes (111) may pass through apertures (108) and (110), sealed by rubber, or metal and rubber composite seals (112) and (113). Catalytic converters may be mounted in compartment (102) or compartment (104). Similarly, coolers for engine oil; transmission oil; oil for a marine propulsion power take off; and an intake air intercooler, may be mounted in either compartment. A further cooling system may be provided for compartment (102), with further cooling air ducts and fans.
Abstract:
A cooling system for a vehicle includes a first cooling circuit coupled to the vehicle engine for cooling the latter and a pump arranged in the first cooling circuit for pumping a coolant to the engine. The system further includes a second cooling circuit for cooling at least one other component in the vehicle, and an arrangement for coupling the second cooling circuit into the first cooling circuit in order to also supply the second cooling circuit with coolant from the pump. The cooling system further includes a line coupled from the first cooling circuit to the second cooling circuit bypassing the coupling means so that the second cooling circuit is supplied with coolant from the pump via the bypass line even when the coupling means is set to the disconnected position.
