High Compression Obtained With the new patented design Hudson motors now are built with a compression ratio of nearly to 1-or 20 per cent above the ever- age-with correspondingly high standards of acceleration, fuel economy and poiver. The company engineers say that it is practically Impossible to make the motor kuock under even the most adverse operat-] ing conditions: The motor is de scribed as the liveliest, most power- ful and economical Hudson has ever! built.

In the patented F-Head design, the intake valve is located in the head of the motor and the exhaust valve at the side. In a way, the motor is valve-in-head as to intake and L-Head design as to exhaust, The intake valve opens to admit fuel in a location just above the ex- haust valve. Hence, it is stated, the coming fuel is drawn direct- ly over the exhaust valve, with a dual effect. First. all "wet" parti. cles of fuel are subjected to the heat of the exhaust valve and chamber. which tends to vaporize them and make them fit for clean and, speedy combustion. Secondly. the exhaust valve is subjected to enough of this cooling action so that it never becomes excessively overheated..

Avoid Knocking Cause Very hot exhaust valves have long been recognized as one of the chief causes of pre-ignition-or knocking-in high compression mo- tors. Hudson engineers have sue- ceeded at once in moderating the valve temperature and at the came Lime making it serve the purpose of a "hot" spot. The fuel charge enters the motor so easily and ex- hausts so cleanly that only moder- ate-size valves are used.

Another important feature of the pulented arrangement is the loca! tion of the spark plug. This is at the extreme side of the combustion chamber. The effect of this is that the first intense explosion of the fuel charge is confined to the small space around the valves. By the time the combustion has extended

SEGRAVE'S. LEAD

IMPETUS TO BRITISH MOTOR TRADE

Major

Segrave's magnificent achievement has done more for the British motoring industry than all the propaganda of the past twelve months, writes Gordon Fraser, the "Daily Express Motor Correspon- dent. While not detracting from his skill and bravery in tackling such a death-defying job as driving a motor-car at nearly four miles a minute, it must be remembered that his success was only made possible by a super car, built and as- sembled by British workmanship, to. the design of one of the greatest motor-car designers in the history of British motoring, and construct- ed of all British materials.

Those who own the New Chevrolet Truck remark on the attention it receives whether it is standing at the curb- winding through traffic-or carrying a capacity load with ease up a steep grade. Its new radiator and hood its smart, full crowned fenders, its low set chassis, and its thoughtfully designed bodies help to assure an appearance of real advertising value.

Let us show you how this new truck will advertise your business for you."
