The term watered-out refers to a well that has begun producing large amounts of water—often occurring with waterflooding for enhanced oil recovery—thereby making oil production unprofitable. Typically, wells are abandoned after they are no longer producing oil or gas at a rate that is economically viable. Bill Bailey et al.

On the other hand, however, the lower exhaust gas temperatures result in a lack of energy for their propulsion on the exhaust side. Their approach was to keep the level of raw emissions low by means of extremely lean and therefore colder combustion, making it possible to dispense with an exhaust aftertreatment system.

Theoretically, cars operating on higher ethanol blends than the design point could emit greater concentrations of pollutants in exhaust gas. In the cylinder where combustion takes place, the fuel evaporates before it is burned, and this evaporation helps cool off the air/fuel mixture and exhaust gas.
