Cooling Tests  for Volvo Diesel Engine Cooling Tests, General Glossary A number of terms are used to define cooling system capacity. Maximum ambient temperature. The maximum ambient temperature the machine may be used in without exceeding the permissible water temperature. Δ t water (delta t) - the temperature differential between radiator inlet and outlet coolant. Δ t air - the temperature differential between radiator inlet and outlet air. Cooling capacity A cooling system installation's cooling capacity is often measured using a reference temperature for coolant boiling point called ATB (Air To Boil). The ATB temperature is defined as the ambient temperature at which the coolant attains its maximum permissible coolant temperature. AOT (Air On Temperature) refers to the maximum permissible coolant temperature after the Volvo engine  of diesel generator set .  It is defined as the temperature of the cooling air entering the charge air co...
