Abstract:
1. A method of limiting a peak temperature of a combustion chamber in an engine, the method comprising: in a first portion of a cycle of the engine— monitoring a temperature of the combustion chamber resulting from the combustion; and in at least one of the first portion or a second portion of the cycle of the engine— when the temperature reaches a predetermined value, injecting coolant directly into the combustion chamber only during at least one of a power stroke and an exhaust stroke of the cycle; wherein injecting fuel directly into the combustion chamber comprises injecting a first fuel that combusts at a first temperature of combustion in the combustion chamber; and wherein injecting the coolant directly into the combustion chamber comprises injecting a second fuel that combusts at a second temperature of combustion in the combustion chamber, wherein the second temperature is less than the first temperature.
