Abstract:
1. An apparatus comprising: an internal combustion engine with at least one piston and at least one cylinder and an intake stream; one or more liquid atomizers in fluid communication with the intake stream structured to provide a plurality of liquid droplets with a mean diameter less than 10 μm to the intake stream; a controller structured to calculate a wet compression level in response to an engine operating limit, wherein the wet compression level corresponds to an amount of liquid determined to fully vaporize substantially throughout compression of the intake stream in the at least one cylinder; and at least one liquid droplet injector connected to a combustion chamber of the at least one cylinder, wherein the one or more liquid atomizers are responsive to the controller to adjust the wet compression level, wherein the at least one liquid droplet injector is configured to directly inject the plurality of liquid droplets from the liquid atomizer into the combustion chamber during compression of the intake stream in the at least one cylinder, and wherein the wet compression level corresponds to an amount of liquid determined to force a transition to a dry compression state after the amount of the liquid fully vaporizes during compression of the intake stream in the at least one cylinder.
