PURPOSE:To make the temperature of cylinders uniform by sensing the temp. of the cooling water, which flows into the cylinder situated oppositely to the intake port as well as the cylinder situated in the neighborhood of the exhaust port, and by supplying the cooling water directly to the later named cylinder if it is turned out necessary according to the sensing result. CONSTITUTION:A pump 5 is on its exhaust side equipped with a by-pass line 9, which shall have an opening in the neighborhood of the suction block of No.2 cylinder 3-2 with tendency to run high temperature, and a flow control valve 10 is installed on the way of this line 9. Thermo-sensors 7, 7' for cooling water are furnished in the suction water jacket 6b of said No.2 cylinder 3-2 and No.6 cylinder 3-6 situated backmost. While the engine is in operation, the water temp. in these cylinders 3-2, 3-6 is measured, and the results are entered into a computer 8. Thereby the said by-pas line 9 is opened by the control valve 10, in case the temp. in No.2 cylinder 3-2 has exceeded that in No.6 cylinder 3-6, to cool the No.2 cylinder 3-2 with fresh cooling water. |
