摘要： 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.

摘要： An internally cooled internal combustion piston engine and method of operating a piston engine is provided, with the combination of liquid water injection, higher compression ratios than conventional engines, and leaner air fuel mixtures than conventional engines. The effective compression ratio of the engines herein is greater than 13:1. The engines may employ gasoline or natural gas and use spark ignition, or the engines may employ a diesel-type fuel and use compression ignition. The liquid water injection provides internal cooling, reducing or eliminating the heat rejection to the radiator, reduces engine knock, and reduces NOx emissions. The method of engine operation using internal cooling with liquid water injection, high compression ratio and lean air fuel mixture allow for more complete and efficient combustion and therefore better thermal efficiency as compared to conventional engines.

摘要： Methods and systems are provided for adjusting engine operation based on estimated vaporized and condensed portions of water injected during a water injection event. In one example, a method may include injecting an amount of water into the intake manifold in response to engine conditions and inferring vaporized and condensed portions of the injected water based on the injected amount and a change in manifold temperature following the injection. Further, the method may include adjusting water injection and engine operating parameters in response the evaporated and/or condensed portion of water.

摘要： A control apparatus for an internal combustion engine according to the invention is applied to an internal combustion engine in which EGR gas and condensed water generated by an EGR cooler are supplied into a cylinder. The control apparatus calculates an equivalence ratio of the internal combustion engine, and controls an EGR valve and a condensed water supply valve such that, when the equivalence ratio is high, a supply rate of the condensed water increases and a supply rate of the EGR gas decreases relative to when the equivalence ratio is low.

摘要： 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.

摘要： Methods and systems are provided for assessing the quality of water in a water injection system using existing engine sensors. A change in manifold charge temperature following a water injection may be compared to a change in intake oxygen level to determine an error between an amount of water delivered to the engine and an amount of water actually used in the engine. The error may be correlated with the water quality and used for correcting subsequent water injection commands.
