GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. CONTROL AND WATER TEMPERATURE. X4240 X 8499 X 766 If thermostat operated shutters on the front of the radiator are definitely cancelled for Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. we ought to consider other schemes for controlling the water temperature. We find that under conditions existing at the present time which is about freezing, unless the radiator is blanked off or muffed, the water temperature does not reach 50°C. We are certain, therefore, that the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) Car, without some means of controlling the water temperature, will not be fit to run under U.S.A. winter conditions or in any other country with similar cold winters. We have had a bitter experience with the 40/50 H.P. cars and all 40/50 H.P. cars supplied in U.S.A. are fitted with shutters on the front of the radiator according to Mr. Royce's recommendations. We think it should be realized from the start that until the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) has some means of controlling the water temperature, it cannot be considered a satisfactory proposition. We are certain that, if ever we send Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) cars to America, there will be a cry because there are no shutters fitted to the radiator. As all 40/50 H.P. cars are fitted with shutters on the front of the radiator, we cannot see that there could be any objection from appearance to the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) being treated in the same way. If it is decided on the English cars we cannot fit shutters conyt'd:- | ||
