Abstract: 본 발명은 차량의 EGR 쿨러로 냉각수를 공급할 수 있도록 하는 차량의 EGR 쿨러 냉각수 공급장치에 관한 것으로,
종래의 장치는 엔진 냉각수가 계속 순환하여 EGR 쿨러의 배기가스 온도를 계속적으로 떨어뜨리게 되지만 EGR 쿨러(20')에 의해 냉각수가 과도하게 냉각되어 CO/HC 발생량이 많아지게 되고, 그에 따라 촉매 백금 로딩량이 많아지게 되는 문제가 있었던 바,
일정 냉각수온 이상에서 내부의 밸브가 열려 차량의 라디에이터로 고온의 냉각수를 공급시키는 써머스탓의 출구측에 EGR 쿨러를 접속하여 써머스탓으로부터 EGR 쿨러로 냉각수를 공급하는 것과, 써머스탓 출구측의 EGR 쿨러 접속 부위에 냉각수온에 따라 개폐되는 냉각수 공급밸브를 설치하여 냉각수온이 낮을 때에 EGR 쿨러에 냉각수가 공급되지 않도록 하는 것 등을 특징으로 하는 본 발명에 의하면 EGR 쿨러로 공급되는 냉각수 온도는 써모스탓 내부의 밸브 특성에 의해 조정 가능하게 되므로 EGR 쿨러로 인한 과도한 냉각을 차단할 수 있게 되어 CO/THC 발생을 저감시킬 수 있게 되고, 그에 따라 촉매 백금 로딩(Loading)량을 저감시킬 수 있게 되어 원가를 절감할 수 있게 되는 등의 효과를 얻을 수 있게 된다.

Abstract: PURPOSE: A device for improving cold startability is provided to improve the startability of an engine by delaying the supply of high-viscosity oil to respective friction parts of the engine. CONSTITUTION: Oil pumped by an oil pump is supplied to a main gallery via an oil cooler and an oil filter. A damper(10) supplies the pumped oil to the oil cooler by storing for a specific time. The damper comprises a housing(13) having an inlet(11) and an outlet(12), a chamber(14) to store the pumped oil in cold starting, a piston(15) to change the capacity of the chamber by moving forward and backward depending on the oil pressure in the chamber, and a spring(16) to apply elasticity. When the capacity of the chamber is maximized, an engine approaches an idle state in a short time. Thereafter, the piston pushes out the oil in the chamber.
