Aircraft fuel question

Indeed. My first car was a pre-war Morris 8 tourer. King pins and steering slack were the major 1961 issues:-)

Just one at a time during testing - although they ran in parallel once installed.

They may not have been as efficient as they might on diesel, as they were designed to run on natural gas. Diesel was only used for testing and then for "Black Start" situations once in use.

In use, one would normally be running and the rig would be producing gas, so the other could start on gas. If both were down, a 1.2MW diesel generator/hydraulic pump would be started, to provide power for starting the main generators on diesel, once the main generators were running, the rig could go back into production and the generators could switch over to gas.

Yes 33% is about right. This was during testing. Once installed on the rig, a waste-heat recovery plant was installed on top - so efficiency would have been higher.

And the Coffman starter for piston engined aircraft, armoured vehicles, etc.

And some had flywheels, cranked up to high speed by small motors or hand cranking and then used to start the engine(s).

I used to instruct in a Stearman. The start procedure was to operate a toggle switch for some number of seconds (now forgotten) to spin the flywheel up to speed and then move the switch in the other direction to engage the flywheel with the engine. Judicious operation of throttle and fuel pump were then needed to get all the cylinders to wake up.

... but WTF has this thread to do with DIY?

uk.d-i-y staying on-topic? You must have noticed that that shipped sailed long ago….

Not sure about the Chieftain but the M1 is claimed to run on anything that will burn.

Waste fuel.

Invented by the Germans !

Don't forget the Detroit Diesel.

The Bus Grease Monkeys youtube channel is devoted to old US buses powered by these engines.

Pony motors.

All John Deere tractors and Cat bulldozers were started with a petrol pony motor that engaged the flywheel of the main engine, where the compression was released with a lever until it had been spun up to speed.

Also the exhaust from the pony motor ran through the inlet manifold of the main engine to preheat the air.

How about a Fire Pump.
