In a modern 14 liter diesel engine about 1 gallon per hour.

There is no idle sensor. Idle speed is computer controlled and is not adjustable.
The idle on a 2001 24 valve is computer controlled and is not adjustable.
How do you adjust the idle speed on a citroen berlingo 1.9d (basic diesel engine)
My 2007 Volvo uses .5-.6 gph at idle (600 rpm), if I set it for a hi idle (900 rpm) it uses 1-1.1 gph.
The usual idle RPM for a diesel engine typically ranges between 600 to 800 RPM, depending on the engine design and application. In some heavy-duty diesel engines, the idle speed may be set slightly higher, around 900 RPM, to ensure proper lubrication and cooling. It's essential to consult the manufacturer's specifications for the exact idle RPM for a specific engine model.
The diesel engine can operate at 12:1 to 24:1 at idle.
There is no required a/f ratio on a diesel. It can be as low as 100:1 at no load idle.
There is no adjuster. The Electronic Control Unit (ECU) sets the idle speed and you can't change it.

Very little, but it is generally considered a bad idea to let it run for long periods of time at regular idle, as the engine does not produce enough heat and can cause fuel washing of the cylinder walls. It may be possible to have the computer adjusted by the dealer so that idle speed can be controlled with the cruise control so that a high idle may be used.
To adjust the idle on a diesel engine semi, locate the idle adjustment screw on the fuel injection pump, which is typically near the throttle linkage. Start the engine and allow it to reach operating temperature. Gradually turn the idle adjustment screw clockwise to increase the idle speed or counterclockwise to decrease it, checking the RPM with a tachometer until the desired idle speed is achieved. Always refer to the manufacturer's specifications for the correct idle RPM range.
