Split type circulating internal combustion engine with water spraying device

A split-cycle internal combustion engine includes a combustion cylinder and a compression cylinder arranged to receive air and compress air to provide compressed working fluid to the combustion cylinder for combustion. The compression cylinder is connected to the water reservoir. The engine further comprises a controller arranged to receive an indication of at least one parameter associated with the engine and/or a fluid associated with the engine, and to control delivery of an amount of water delivered to the compression cylinder based on the indication of the at least one parameter, such that the total amount of water in the compressed working fluid at the end of the compression stroke is such that the water concentration level in the compressed working fluid is less than the threshold water concentration level. 分体式循环内燃机包括燃烧气缸和压缩气缸，压缩气缸被布置为接收空气并压缩空气以向燃烧气缸提供压缩的工作流体用于燃烧。压缩气缸连接到水储存器。该发动机还包括控制器，该控制器被布置为接收与发动机和/或与该发动机相关联的流体相关联的至少一个参数的指示，并基于至少一个参数的指示控制输送到压缩气缸的水的量的输送，使得压缩冲程结束时压缩的工作流体中的水的总量使得压缩的工作流体中的水浓度水平小于阈值水浓度水平
