Editing Air-start system (section)

===Starter motor===
Another method of air-starting an internal combustion engine is by using compressed air or gas to drive a fluid motor in place of an electric motor.<ref>{{cite web |title=Air Starters |url=https://www.galigrup.com/en/producto/components-for-diesel-and-gas-engines/air-starter/ |access-date=2023-11-07 |website=GALI |publisher=galigrup.com}}</ref> They can be used to start engines from 5 to 320 liters in size and if more starting power is necessary two or more motors can be used. Starters of this type are used in place of electric motors because of their lighter weight and higher reliability. They can also outlast an electric starter by a factor of three and are easier to rebuild. Engines operating in underground mining activities tend to operate on this type of starter system to reduce the risk of an electrical system igniting flammable material.

All vane type air starters should have a lubricator installed to insure long-life and maximum performance.<ref>{{cite web|url=https://ascairstarter.com/bdKeJO22q0Jjw/?page_id=20|title=Frequently asked questions|website=Air Starter Components}}</ref> Lubricators give the moving parts a needed friction barrier, reduce metal corrosion and keep vanes sealed properly against the cylinder walls. Even the so-called lube-free air starters require lubrication to prolong trouble free life. Two basic lubricator devices are typically employed. One is an in-line or reservoir type that typically stores up to 2 quarts of lubricant, and is installed along the air supply line. The second style of lubricator is a small one shot device that dispenses a measured amount of lubricant every time the starter is engaged. Installed directly onto the air inlet of the starter, the in-line lubricators are self priming pneumatic pumps that require a 1/4″ lubrication line piped from as far away as 4 feet. Air Starter lubricators perform best using misting type, non-detergent oils such as diesel fuel or Marvel Mystery oil. If emissions are a concern, there are environmentally friendly type lubricants available on the market.

Not all air starters require lubrication.  Turbine type air starters do not require air motor lubrication, although some turbine air starters do use an oil filled transmission that may require periodic inspections and maintenance.
