Fuel Injected World War II Tank Engines?

The HL234 was a proposed fuel injected variant of the Maybach HL230 which would have increased power output from 690 horsepower to 800 or 900 horsepower. The Maybach HL230 saw service in the Panther, Tiger I, and Tiger II (among other vehicles), so the HL234 would have been used on those vehicles. What if the HL234 or other fuel injected engines had seen use in tanks during World War II?

It would've cut specific consumption of gasoline engines - an important thing for everyone, especially for Germany in ww2; non-issuse for the Soviets since they used diesel engines anyway, the British were also not big in gasoline tank engines before 2nd half of the war. Shortcoming: the tank engines became more expensive.
 
And more maintenance intensive. Don't overlook the fact that battlefield repair ability was a key element in how good a tank was or wasn't.
 
Fuel injection, purely mechanical in those days, was more expensive and less reliable. However, could use of fuel injection in those tanks allowed for an increase in the civilian fuel rations?

AIUI, early fuel injection systems made for worse (increased) fuel consumption, not better. We must remember this is the days of mechanical, not electronic fuel injection.

I wonder if this issue would also apply https://en.wikipedia.org/wiki/Mercedes-Benz_300_SL

However, unlike today's electrically powered fuel injection systems, the 300 SL's mechanical fuel pump would continue to inject gasoline into the engine during the interval between shutting off the ignition and the engine's coming to a stop; this unburned gasoline washed lubricating oil from the cylinder walls, which not only left them unprotected in affected areas during start-up but would dilute the engine's entire oil supply if the car was not driven hard or long enough to reach a sufficient temperature to evaporate the gas out of the oil.

Best fuel injection engine for German tanks would have been a land-version of the two-stroke Junkers Jumo 205 diesel, or the turbocharged 207.


Of course, t
he easiest route to a German army fuel injected diesel engine is if GM's Opel division builds the GM diesel in the late 1930s, https://en.wikipedia.org/wiki/Detroit_Diesel_Series_71

Early gasoline fuel injection was mechanical, and typically would run well only at a single RPM range. Pick top RPM, idle will suffer, usually too rich, that will wreck rings as oil is washed off the cylinder walls.
GM tried it in the late '50s, and went back to carbs over reliability and driveability concerns, especially in cold weather. They typically didn't have a dedicated idle mixture/accelerator pump circuit.
 
Diesel fuel injection systems were also mechanical, but diesel engines have a narrower speed range.

Germany's Borgward group apparently tried direct fuel injection on two-stroke petrol engines in the Goliath and Gutbrod cars. This avoided fuel leaking out the exhaust as happens in carburetted two-stroke engines. But apparently many of these cars were converted aftermarket to carburetted two-stroke.
