Packard Fuelizer
The Packard Fuelizer is an ascending flow carburetor with integrated mixture preheating by burning gasoline, which the Packard Motor Car Company built from approx. 1920 to 1924 and used in its own vehicles.
purpose
The aim was a better mixture preparation and better cold start properties. At that time, petrol with a high boiling point could cause the engine to run unsteadily because the non-evaporated part of the fuel did not reach the cylinder due to the rising flow carburetor and the mixture was too lean .
functionality
The device consists of a small combustion chamber with its own spark plug and coil , in which a small amount of gasoline is burned to heat the intake manifold. The gasoline / air mixture can be adjusted using a sight glass for monitoring. If the flame burns evenly blue, the system is working correctly.
Better quality gasoline on the market made the system redundant. Packard continued to build its own carburetors until 1929 (6th series) and then bought downdraft carburetors from Detroit Lubricator .
application
Packard used carburetors with fuelizers for the first time in the Twin Six of the 3rd series (series 3-35) from model year 1920. The 3-35 had already been introduced in 1918. Fuelizers were used until 1924; most recently in the Single Six of the 2nd series (series 226 and 233) and in the Single Eight of the 1st series (series 136 and 143).
