Active draining of engine cooling system
A cooling system for a marine inboard internal combustion engine includes at least one engine cooling passage disposed in thermal communication with heat emitting portions of the engine. A pump is in fluid communication with the at least one engine cooling passage. The pump draws cooling water out of the at least one engine cooling passage. At least one outlet drain is downstream of the pump for discharging the cooling water that was pumped out of the at least one cooling passage. A switch activates the pump in response to the following: an operator command to stop the engine and/or a speed of the engine being below a threshold speed.
Cooling system
A cooling system includes an electric pump, a cooling target temperature sensor, a coolant temperature sensor, and an electronic control unit. The electric pump pumps a coolant to a circulation channel connected to an inlet and an outlet of a cooling channel in which heat is exchanged with a cooling target. The cooling target temperature sensor detects a cooling target temperature. The coolant temperature sensor is arranged upstream of the inlet in the circulation channel, and detects a coolant temperature. The electronic control unit controls driving of the electric pump so that a discharge flow rate of the electric pump matches a target flow rate, and sets the target flow rate using an equation based on a reference value obtained by dividing a difference between the cooling target temperature and a target cooling temperature of the cooling target by a difference between the cooling target temperature and the coolant temperature.
Method and system for an engine assembly
Methods and systems are provided for an internal combustion engine assembly comprising a water pump driven by a crankcase venting system. In one example, a method may include adjusting a transmission ratio of a magnetic transmission in response to a temperature of an engine, wherein the magnetic transmission connects a water pump to a crankcase venting system of the engine.
Exhaust gas purification apparatus for internal combustion engine
The separation efficiency of carbon dioxide is improved by making the temperature of exhaust gas further low. An exhaust gas purification apparatus for an internal combustion engine includes a first heat exchanger arranged in an exhaust passage of an internal combustion engine and configured to carry out heat exchange between outside air and exhaust gas of the internal combustion engine, a second heat exchanger arranged in the exhaust passage and configured to carry out heat exchange between a circulating heating medium and the exhaust gas, and a carbon dioxide separator arranged in the exhaust passage at the downstream side of the first heat exchanger and the second heat exchanger and configured to separate carbon dioxide from the exhaust gas.
Vehicle thermal management system applying an integrated thermal management valve and a cooling circuit control method thereof
A vehicle thermal management system includes an Integrated Thermal Management Valve (ITM) for receiving engine coolant through a coolant inlet connected to an engine coolant outlet of an engine, and for distributing the engine coolant flowing out toward a radiator through a coolant outlet flow path connected to a heat exchange system. The heat exchange system includes at least one among a heater core, an Exhaust Gas Recirculation (EGR) cooler, an oil warmer, an Auto Transmission Fluid (ATF) warmer, and the radiator. The thermal management system includes a water pump positioned at the front end of the engine coolant inlet of the engine and a coolant branch flow path branched at the front end of an engine coolant inlet to be connected to the coolant outlet flow path.
Vehicle thermal management system applying an integrated thermal management valve and a cooling circuit control method thereof
A vehicle thermal management system includes a plurality of coolant circulation/distribution systems that form an engine coolant flow, which circulates in an engine via mechanic/electronic water pumps, a heater core, High Temperature (HT)/Low Temperature (LT) radiators, an Exhaust Gas Recirculation (EGR) cooler, an oil warmer, an Auto Transmission Fluid (ATF) warmer, and an intercooler, in association with an Integrated Thermal Management Valve (ITM) and a Smart Single Valve (SSV). The thermal management system prevents turbo boiling at Ignition Key Off in association with the SSV and an Electric Water Pump (EWP) of the water-cooled intercooler while quickly implementing warm-up of the engine and the engine oil/ATF oil by the four-port layout of the ITM at the same time.
