Here's an engine rarely seen since they were intended to be disposable. This is the 4 cylinder radial engine from a WWII German G7A torpedo. It ran on Decaline fuel (decahydronaphthalene), which was first burned using compressed air (stored in a tank onboard) as an oxidizer. The combustion byproducts were then passed through a device called a 'wet heater', which also introduced water (from a 57L storage tank) to produce superheated steam. This high pressure mixture of superheated steam and compressed air was finally sent through the engine to drive the pistons.

Since the entire internal combustion/steam generator system was self-contained inside the hull of the torpedo, it could run underwater. The 4 cylinder, 'X' type radial engine produced up to 350 horsepower at its maximum power setting, which was enough to push the 26' (just over 7 meters) torpedo (the length of a large Uhaul moving van here in the States for comparison purposes) along at nearly 50mph while submerged.

Interesting piece of history-and worth remembering-in my opinion.

It never ceases to amaze me of the many ingenious ways we invent to kill each other. That said we got a lot of new technology that way.

ICE 101 for today's lesson.

This is a 1943 Ford 1,100 HP Hemi Sherman Tank Engine with triple 4 barrel carbs.

So this thing is 1100ci 1050lbs/ft of torque and 500hp stock. 5.4in bore 6in stroke and was all aluminum. Some guy put one in a 1970 Mustang, well because he could

It took him 18 liters to get the power of a 6.7 power stroke diesel engine, but good for him.
That's in 1940, pretty crazy what it took to make that power back then and as for the car, why not?

That 18 liters made it through warranty though 🤣

As someone who wrenches on both modern crap now, and old crap, pretty sure there won't be many surviving current motors in 80 years. It seems longevity is measured by warranty, gambled on by companies and hindered by the EPA.
