Grand Prize of the LCF.
Together with the chain drive of the past large slow-speed engines, and subsequently a working volume of road racing will never exceed 6 liters.
In 1913, ACF has returned to the restriction of consumption. As a racing formula consumption rate was set 20 liters per 100 km and the mass of the car not filled 800-1100 kg. Allowed to race cars with number of cylinders for at least four, equipped with a two-seater body with a cylindrical gasoline tank of 1 m for the driver's seat. Install the tank fairings to reduce air resistance was not resolved.
Participant’s race in 1913 showed excellent efficiency at high average speeds. Motor vehicle, "Peugeot"
The visitor first car "Peugeot" is a remnant of fuel 22 liter, which came second - 28 liters.
The racing formula in 1914 was a major factor engine capacity. The maximum amount designated 4.5 liters, the maximum mass of 1100 kg.
It was attended by an exceptionally strong quantitative and qualitative. Engines of all firms had hipped combustion chamber and the upper valves, except for one valve less engine, ten out of thirteen firms used cylinder heads with four valves, one - three and one - two. On vehicles four firms were installed brakes on the front and rear wheels. Vehicle weight fluctuated between 900 and 1050 kg.
After a bitter struggle with the "Peugeot" the first three prizes was a car "Mercedes", on an equal rapidity "Peugeot", but more rugged and reliable. Inhibition of all-wheel drive found its advantages in areas with many twists and turns cars with brakes on all wheels consistently showed a higher average speed.
Limiting displacement promoted an increase in the next liter capacity.
In addition to the ACF Grand Prix, is of considerable interest in the Cup race small cars (Coupe des voiturettes), organized in France in 1906-1913 years. And in 1920-1923 years. At small cars meant at first light weight vehicles, mainly equipped with one-or two-cylinder engine, are low cost and have received so widespread. Already at that time argued that the main type of vehicle - an easy economical machine, designed for the mass market. Small cars while in most cases had an engine capacity of 1.5-3 liters. That car of this category should be considered as precursors of racing cars that have received distribution later in the period of 1921-1934 and 1938 - 1939 year and modern racing cars, having approximately the same displacement. |
