Sherman M4A2 Detroit Injectors

[Malcolm Towrie]

Interesting, Andrew. Any idea why liners would have to be changed?

I would have thought blower output would be a factor too. Dumping more fuel in would require more air, at least at wide open throttle when the engine doesn’t have excess air. It’s gotta be able to burn all that extra fuel, not just belch it out as black smoke!

Each injector type doesn’t just squirt a controlled amount of fuel in over the throttle range, it controls the timing of the injection too by varying the shape of the helix cutout in the plunger.

Never worked on a diesel before. There’s a lot to learn!
