Air compressor Fast Idle

[jstcrwl]

    This is for all you York compressor guys. This is designed to raise your engine idle while the compressor is running (give you more volume of air) and then return to a normal idle when the compressor cuts out. This can be a great benefit when using compressed air for extended repairs. The engine will idle when you are not using air. When you start using air the idle will increase when the compressor clutch engages. Then when the compressor clutch disengages the engine idle will return to normal. Then another additional feature is an auxiliary switch that will enable the fast idle constantly(very useful when working as a winch point). Then as a safety feature the fast idle works off a relay wired to the parking brake. This will deactivate the fast idle when the parking brake is released. So you can driving down the trail and engage you belt driven air compressor. The compressor clutch will engage and the compressor will make compressed air. Your fast idle will not be active. Once you set your parking brake the fast idle system will become active. How the fast idle is achieved is with a linier air cylinder attached to the throttle with a control valve. I used air because it had less of a current draw on the electrical system. You can use an electric actuator but the to handle the load of moving the throttle from idle is more than you might expect. Plus I used air cylinder because that was what I found lying around. Keep in mind the cylinder I am using on my set up is larger than what is required. Like I said it is what I found lying around. Also you can even find air cylinders with a built in control valve. Attached is a wireing diagram and pictures of my air cylinder install and air valve.

I will see you on the trail,
