OK Shane, I’m going to take a walk on the wild side and respond to your question. Please note that I will not use “never” or “always” because there are more ways to regulate fuel and/or air than I can count. In yesterdays spark ignition engines (gasoline and others) fuel was mixed with air in a carburetor. To regulate the amount of fuel leaving the carburetor and entering the engine, a mechanism to close off or restrict the air/fuel mixture was used called a throttle. Even on today’s spark ignition engines, you may or may not find a carburetor as such, but you will still find some mechanism to “throttle” the air entering the engine so that it is proportional to the amount of fuel delivered (regardless of how the fuel gets there).

Now, a diesel compresses a full cylinder of air to generate energy for autoignition (no spark plug). You wind up with a desirable energy effecient lean fuel mixture. As such the diesel engine does not need an apparatus for restricting or “throttling” the combustion air. The fuel flow is regulated as necessary to control the energy into the engine, but the air is not. Thus, no “throttle”.

So where does that leave us? As your asked, what does it have then? We can’t call it a gas lever. We can’t call it an accelerator or someone one this forum would ask where is the de-accelerator. We can’t call it a throttle if it is a diesel. And to make matters worse, even on a gas tractor this lever isn’t even directly connected to the “throttle” (air restricter) on the engine like the gas pedal would be on automobiles. The dang thing is connected to the governor and the governor connects to the “throttle” (your car probably does not have a governor). So to eliminate any confusion in the future, I suggest we call it the “thingy by the steering wheel “ or the “governor speed setting lever”. What do yall think? I am open to suggestions.

have fun

matthew
