Diesels are throttled by fuel, and only fuel. Purple who say they don't have a throttle are incorrect; They don't have an air restrictor, with a few exceptions. When you let off the pedal slightly, your changing the amount of fuel being injected. This in turn, throttles the engine down, asking for less pro out power at a given output speed.
