A charge air cooler (CAC) condensation dispersion system including a compressor for generating a hot compressed air flow; a CAC having an inlet tank for receiving the hot compressed air flow and an outlet tank for discharging a cooled compressed air flow; a condensate pickup tube having an inlet disposed in a lower volume of space within the outlet tank and an opposite outlet; and a condensate conveyance tube having a first end connected to the outlet of the pickup tube and an opposite second in in fluid connection with the inlet of the compressor. A solenoid actuated control valve is disposed in-line with the condensate conveyance tube. A controller configured to send a signal to the solenoid valve to selectively cycle the control valve between an open state and a closed state. An in-line orifice plate is disposed adjacent the second end of the condensate conveyance tube.

Injection method and system for the injection of water in an internal combustion engine; the following steps are substantially comprised: operating, when the internal combustion engine is turned on, a reversible pump in order to suck water from a tank and feed the water under pressure to an injector through a feeding duct; cyclically opening, when the internal combustion engine is turned on, the injector in order to inject the water towards at least one cylinder of the internal combustion engine; and draining the water, when the internal combustion engine is turned off, from the injector and the feeding duct by using a release valve connecting the feeding duct to the outside.

A control device for an internal combustion engine which is provided with an engine body, a water injector for injecting water to the inside of an intake passage of the engine body, and a fuel injector for injecting fuel to be made to burn inside a combustion chamber of the engine body. The control device is provided with a water injection control part controlling the amount of injection of water from the water injector in the combustion cycle where fuel is injected from the fuel injector so that water vaporizing inside the intake passage during the suction stroke and water vaporizing inside the combustion chamber during the compression stroke are generated.

A water injection system for spraying water toward an intake system of an engine is disclosed. The water injection system includes a water collection circuit that has a water collection pipe for collecting water from the intake system and a drain valve installed on the water collection pipe. The water collection circuit collects water from the intake system of the engine by opening the drain valve when amount of stagnant water in the intake system reaches a predetermined threshold.

Methods and systems are provided for coordinating water usage with spark usage based on the effect on an engine torque ratio. Water is injected based on torque ratio at a current spark timing relative to torque ratio at borderline knock to improve the impact of the water injection on the engine performance. Manifold water injection and direct water injected are coordinated based on intake manifold humidity.
