<p><P>PROBLEM TO BE SOLVED: To miniaturize a system and improve start up property of the system in a catalyst reaction type coolant heating system heating coolant with using catalyst reaction. <P>SOLUTION: This system is provided with an heat exchanging part 10 including a mixed gas passage 12 supplying mixed gas of fuel and air and a coolant passage 13 supplying coolant and exchanging heat with the mixed gas passage 12, fuel supplying means 30, 31, 33, 34, 36 supplying fuel, an air supplying means 32 supplying air, and a coolant supplying means 22 supplying coolant, and an oxidation catalyst 15 for promoting catalyst reaction of the mixed gas is carried at an upstream part in a direction of mixed gas flow in the mixed gas passage at least. The system is provided with a temperature sensor 18 detecting catalyst reaction temperature of the mixed gas and a control part 40 controlling flow rate of at least one of fuel, air or coolant based on catalyst reaction temperature. <P>COPYRIGHT: (C)2003,JPO</p> |
