Lars Grimsrud is a retired aerospace engineer and performance automobile enthusiast who has become a celebrity amongst owners of carbureted Chevrolet Corvettes and GM muscle cars for his skill at tuning their engines. Lars Grimsrud was born in Norway.
The Fish carburetor was also sensitive to mass airflow, rather than volume airflow, making it self-compensating for changes due to temperature or altitude. [ 1 ] A second problem with the conventional carburetor was its good performance in steady conditions, but poor progression: its dynamic ability to respond, such as when suddenly opening the ...
The brothers then concentrated on the manufacturing of carburetors and ignition systems. [5] As a result of the Motorette Henry Ford commissioned the brothers to produce a carburetor for his Model T. "The carburetor they built for Ford was an immediate success and the brothers founded Holley Carburetor Co., which became one of Ford's biggest ...
Two-barrel downdraft Holley 2280 carburetor Cross-sectional schematic. A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4]
Older engines drew air directly from the surroundings into each individual carburetor. Modern engines instead draw air into an airbox, which is connected by individual hoses to each carburetor or directly to the intake ports in fuel-injected engines, thus avoiding an extra intake manifold.
These were arranged so that each cylinder of the engine had its own carburetor barrel. These carburetors found use in Maserati and Alfa Romeo racing cars. Twin updraft Weber carburetors fed superchargers on the 1938 Alfa Romeo 8C competition vehicles. [2] Fiat assumed control of the company in 1952 following Weber's disappearance in 1945.
This led to fitment problems on twin carb installation. Amal introduced a "chopped" version of the 376 and 389 without the float chamber so twin carburettors could be fitted. Both carbs were fed from the float chamber of the left hand carb. [16] Triumph twins used two chopped monoblocs and a remote float chamber mounted centrally behind the carbs.
Ram-air intake on a Kawasaki ZX-12R. A ram-air intake is any intake design which uses the dynamic air pressure created by vehicle motion, or ram pressure, to increase the static air pressure inside of the intake manifold on an internal combustion engine, thus allowing a greater massflow through the engine and hence increasing engine power.
