The Quadrajet is a four barrel carburetor with a "spread bore" throttle plate, made by the Rochester Products Division of General Motors. Its first application was the new-for-1965 Chevy 396ci engine .
A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used. For example, an extra "closed throttle position ...
The Quadrajet became computer controlled in 1980 in California and in 1981 in the rest of the states; its last application was on the 1990 Cadillac Brougham and 1990 full size GM station wagons with the Olds 307 engine. [citation needed] RPD was a pioneer in fuel injection systems in road cars in the 1980s.
The CCC system included the electronic Rochester 4-bbl E4ME Quadra-Jet, with computer-adjusted fuel metering on the primary venturis and a throttle position sensor allowing the CCC to calculate engine load. In the ignition system, CCC was fully responsible for the timing curve; mechanical and vacuum advances were eliminated from the distributor.
In 1985, the 4.3 L (262 cu in) was either equipped with throttle-body fuel injection (RPO LB4) or a Rochester Quadrajet four-barrel carburetor (RPO LB1). The Chevrolet Caprice, Chevrolet Monte Carlo, Chevrolet El Camino , Pontiac Parisienne, and Pontiac Grand Prix used the LB4 rated at 130 hp (97 kW).
At lesser throttle openings, the air speed through the venturi may be insufficient to maintain the fuel flow, so then the fuel may be supplied by the carburetor's idle and off-idle circuits. At greater throttle openings, the speed of air passing through the venturi increases, which lowers the pressure of the air and draws more fuel into the ...
