    water injection to gas engines

    Andybee: I agree with you about better performance on wet days, I happened to notice that a lot when I had a small VESPA scooter with a 150cc two stroke engine. Of course someone living in Vancouver may not notice a diference year round, while someone in Las Vegas might. Just one coment about...

    water injection to gas engines

    ErickFahlgreen.- Very good work, I will study the charts. SBBlue.- That is a good point and one more reason to consider water as an option to increase power and efficiency. Patprimer.- I think the clue is that what you are modifying is the relative humidity of the air while entering the...

    water injection to gas engines

    REDMANE Good point, I overlooked the expansion factor of the water in the combustion. But still the issue is if it would be practical to install a water inyection system on passenger cars for intance or diesel truck engines. The volume of water would need to be controled in proportion to the...

    water injection to gas engines

    Pat: I think the clue is not what happens inside the cylinder but on how much oxygen enters the system and I think more oxygen enters as a result of the reduced volume by cooling the air before entering the chamber. What happens afterwards, inside the cylinder is another system. I think, for...

    water injection to gas engines

    To Greg Locock: Greg, whay I am sure about is that if to dry hot air you add water the air cools significantly and following the law of gases, if you cool a gas it reduces its volume and if the oxygen content remains the same that means you actually put more oxygen per cubic feet of air to the...

    water injection to gas engines

    Some time ago I was looking for options to inject water to a gasoline engine to improve power and milage and read several of the opinions. I got discouraged because the practicality of it was not there to compensate for the trouble, but I was surprised nobody could explain why the water injected...
