Operation Ambient conditions 24 © 2009 z Depending on the type of engine, glow plugs, heating plugs, heating flange, flame glow system can be used as cold starting aids.( 27 ) Reason: Air density decreases as altitude or ambient temperature increase. This reduces the amount of oxygen in the engine intake air and the fuel-air mix- ture would be too rich if the injected amount of fuel were not reduced. z The results would be: black smoke in the exhaust high engine temperature reduction in engine performance possible impairment of starting behaviour Consult your equipment supplier or DEUTZ partner if you have any other questions. z Observe the mixing ratio anti-freeze/cooling wa- ter.
