Default Repost of "Is this possible or probably" mistakenl

I will get the hang of forum administration eventually:

Richard L post:

I have read a few SAE papers on this topic - no details but passing comments, can anyone make some sense on the following claims:

During the induction stroke, when water-mist/air is induced and passed the inlet valves, there is a progressive pressure drop as the piston is moving downward. Two things are happening concurrently - Further evapoarion of water droplets will accelerate due to pressure drop inside the chamber as well as the heated surroundings prior to the exhaust stroke.

Water inejction will have a positive effect on the volumetric efficiency.

It would be great with someone can say if that is possible or probable? I have no view on this claim.

My response previously:

Add to that the improvement in VE as a result of absorbing the heat risidual in the valve on the way into the cylinder, plus the heat of friction move past the valve (maintains charge density).

Please add feedback.
