"Col" Laboratory Because motor car engines are expected to start and keep operating without regard to weather, intensive study has been given by the industry to the effect of sub-zero temperature on motors.
In the laboratories of the Packard Motor Car Ca. plant there is a j "cold room" in which the temperature can be lowered to a point considerably below that which is likely to occur in even the coldest spot where a motor car would be used. Research work conducted in this room has resulted in the adoption by Packard of a number of important features designed to offset the effects of cold weather on automobile engines.
One of these is a system by which the hot. exhaust gases from the cylinders are diverted into a passage around the centre of the intake manifold when the engine is first started. This serves to warm the petrol and air mixture from the carburetter causing the gasoline to vaporize more readily. After the engine has reached operating temperature the exhaust is turned back, By automatic action of a thermostat, to follow its normal course through the muffler.
In addition to this heat control there is a thermostat in the waler line to the radiator on the One-Ten and One-Twenty. It confines circulation of the cooling water to the engine alone until ting temperature is reached. the th most at opens a valve which permits the water to circulate through the radiator. In the One-Sixty and One-Eighty comparable results in this connection are obtained through use
