摘要： A device for controlling a pressure of an oil pump in a vehicle is provided to. The device includes a sensor that detects an inclination of a vehicle and an oil pump that pumps oil in an oil pan to pressure transfer the oil to an engine of the vehicle. A controller determines an inclination value of the vehicle based on the information from the sensor and adjusts the operating mode of the oil pump to adjust the pressure of the oil supplied to the engine.

摘要： The present invention relates to a technology that can simultaneously control the flow rate of a coolant and perform variable separate cooling by controlling the opening rate of a flow control valve. The flow control valve has an inlet port connected to a coolant outlet of a cylinder block and a plurality of outlet ports connected to a cooling inlet port of an engine such that the opening rate of a first outlet port is symmetrically changed in a first direction and a second direction from a mid-operation angle of the entire operation section of the flow control valve.

摘要： A flow control valve is arranged to simultaneously perform coolant flow control and variable split cooling, according to control of a path opening degree of the flow control valve. The flow control valve can perform four-port control for variably controlling four ports at once by operation of the flow control valve, and thus can implement variable temperature control for increasing a temperature of an engine, rapid warming-up of the engine, while performing split cooling at the same time.

摘要： A cooling system for vehicles and a control method thereof improves indoor heating performance and fuel efficiency by controlling a flow rate of a coolant passing through a heater core together with an EGR cooler. A coolant having an increased temperature is first supplied to the heater core side through a flow stagnancy control to rapidly increase the temperature of the coolant flowing in the heater core, thereby improving heating performance. A warm-up feature is improved through an exhaust heat recovery function by a heat exchange between the exhaust gas and the coolant in the EGR cooler, thereby improving efficiency of fuel.

摘要： A flow control valve apparatus is provided in which a main valve adjusts the flow rate of cooling water by operating a plurality of ports and a sub-valve that operates with the main valve adjusts the flow rates of the cooling water circulating through a cylinder block and a cylinder head. The flow rate of the cooling water is variously adjusted based on the operation conditions of a vehicle.

摘要： The present disclosure provides a split cooling apparatus for an internal combustion engine, the apparatus including: a base inserted into a water jacket of a cylinder block, the base surrounding an outside of a cylinder along a shape of the cylinder; an insertion groove formed on the base by being depressed into an inner surface of the base; and a sealing member inserted into the insertion groove, wherein when a temperature of cooling water supplied into the water jacket reaches a preset temperature or higher, the sealing member expands so as to close a flow passage between the base and the cylinder, thereby increasing flow resistance of the cooling water and thus reducing a heat transfer rate of the cylinder.
