Hemmings Motor News Blog

Hemmings Motor News has been around since 1954. We're proud of our heritage, but we're also more than the Hemmings full of classifieds that your father subscribed to. Aside from new editorial content every month in Hemmings, we have three monthly magazines: Hemmings Muscle Machines, Hemmings Classic Car and Hemmings Sports and Exotic Car.

While our editors traverse the country to find the best content for those magazines, we find other oddities related to the old-car hobby that we really had no place for - until now. With this blog, we're giving you a behind-the-scenes look at what we see and what we do during the course of putting out some of the finest automotive magazines you'll ever read.

The Rambler Rebel’s Fuel Injection – The Dream and the Legend

Posted June 29, 2017 9:00 AM by dstrohl

[Editor’s Note: After the recent story on the Rambler Rebel’s 60th anniversary, we thought we’d include this section from Bill Lenharth‘s book, “The Amazing Rambler Rebel,” which explains the most misunderstood aspect of the Rebel: its never-produced electronic fuel injection system.]

The Rambler Rebel’s basic design program was innovative and set the tone for the future of a distinct class of automobile. The car itself also had very innovative components, among them electronic fuel injection. The fuel injection system was unique in the design concepts that it employed. These same concepts would continue to be used in the fuel injection system of vehicles into the 21st century.

The development of what was to become the Bendix Electrojector System started in 1953 at the Bendix Corporation. The Bendix company decided to explore the concept of an electronic fuel injection system as a replacement for the standard carburetor that would solve all of the carburetor’s very well known problems.

How the fuel injector became economical for all autos, and from there the industry standard.

Was that the same Bendix Fuel Injection System that was briefly and unsuccessfully used by Chrysler?

Sure, it was innovative, but having to wait 2 - 3 minutes for the vacuum tubes to warm up before you could start your engine was a inconvenience.

I have to give you two thumbs up on that answer, as it is spot on, and appropriate, and clever beyond words!

My question: How hard would it be to get rid of carburetor on old Tecumseh engine, and install some sort of mechanical fuel injector that runs off the output shaft? I would like to attempt making one, but let me add, I only expect this to inject into the air supply as a fine mist, measured so carefully as not to flood the intake by leaving a liquid residue for the engine to ingest. Or we could go electronic really easily with some sort of electronic gizmo that runs in phase with the intake valve.

I think it might be hard to port the thing for direct liquid fuel injection.

According to the Chrysler engineers who worked with/on this system, it was faulty wax-impregnated capacitors, not tubes, that did the system in, because by the time it was being used by Chrysler, Bendix had converted it from vacuum tubes to transistors.
