I think you are sending him up the wrong path, the air entering a diesel engine does not need to be measured for it to run. Pressing the throttle just injects more fuel into the cylinders which increases rpm. I've done a bit more reading up on it, a throttle body on a diesel is usually wide open under normal running and only closes partially to raise combustion temperature, this is required to make sure the egr and dpf if fitted works correctly. It will close completely when shutting engine off to act as an air shut off valve in case of run on.
