Title: Adjuster for cooling water flow in engine
Inventor: LEE HYEON SIK
IPC: F01P3/20
Filed: 1998-12-03
Abstract: PURPOSE: An adjuster is provided to adjust cooling water flow in an engine in order to reduce hydrocarbon amount generated when the engine first starts. CONSTITUTION: While the temperature of cooling water is less than 60% of the set normal temperature, a controller(70) outputs a bypass closing signal and a heater core closing signal to a valve driver(60). Thus, a bypass control valve(40) and a heater core control valve(50) are closed and cooling water circulates in a cylinder block and a cylinder head water jacket inside an engine(10) without moving to a bypass hose(18) or a heater core hose(19). Therefore, an adjuster for cooling water flow shortens a circulating passage and time until cooling water temperature reaches to the normal temperature so as to reduce the generation of hydrocarbon caused by incomplete combustion and to increase fuel efficiency of the engine.
