When did Chevy inject fuel?
1956
Chevrolet introduced a mechanical fuel injection option, made by General Motors’ Rochester Products division, for its 283 V8 engine in 1956. It has become the primary fuel delivery system used in automotive engines, having replaced carburetors during the 1980s and 1990s.
How does the fuel injection system work on a corvette?
Carburetors and fuel-injection systems are fuel managers feeding your engine the required fuel load from idle to WOT and everything in between. Electronic fuel-injection systems precisely feed fuel while monitoring the engine’s efficiency through various sensors, providing the best possible fuel control.
What kind of fuel system does a C3 Corvette have?
All others until 1981 had Rochester Quadrajet carburetors, then an archaic electronic fuel injection finished off the Shark’s C3 generation for 1982. One backfire can ruin your afternoon if your pre-1992 Holley 4150, 4160, 4165, or 4175 does not have this power valve modification done to its base plate.
How does the power piston system work on a corvette?
The power piston system uses a stepped needle that restricts fuel flow through the jets, while the power valve uses a single orifice to meter fuel to the jets. Both power enrichment systems use engine vacuum to control fuel flow rate: as engine vacuum decreases relative to throttle opening so does the fuel flow restriction.
Can a EFI system be installed on a C3 Corvette?
However, many aftermarket EFI systems can be installed on a C3 for improved performance, and it’s a system that constantly adapts to changing conditions. This Tech Tip is From the Full Book, CORVETTE C3 1968-1982: HOW TO BUILD AND MODIFY.
