Abstract : This work was performed to provide information on a number of aspects related to direct water injection for total cooling of diesel engines. Based on tests using a single-cylinder CLR (Labeco) engine, the following determinations have been made: Water-injection total cooling can be accomplished over a very wide range of parameters; including injection timing; spray patterning, speed, and fuel rate. Port injection or even port induction of liquid can be used. Under some few conditions, only partial cooling is possible. Results show total cooling by direct water injection can be accomplished with increased power and better BSFC. (Modified author abstract)
