Crower steam expansion stroke for two stroke/rotary engines

In summary, the conversation discussed the possibility of incorporating a steam expansion power stroke into a two stroke or rotary engine. The main concern was whether the presence of compressed air in the combustion chamber would affect the vaporization of injected water. The use of steam expansion to regulate engine temperature was also considered. The main design features of a practical engine were also mentioned as a topic for discussion.

I was interested in whether it might be possible to incorporate a steam expansion power stroke into a two stroke or a rotary engine. The difference would be that unlike the convention Crower six stroke cycle there would be compressed air in the combustion chamber, without some sort of valve system that I can not begin to imagine when the water was injected. Would the compressed air interfere with the vaporization of the injected water or would the vaporization proceed normally.

It would be highly advantageous to use steam expansion as the means of regulating engine temperature, especially for rotary engines.

What is a Crower steam expansion stroke for two stroke/rotary engines?

A Crower steam expansion stroke is a type of engine design that utilizes steam to expand and provide power during the power stroke. It is used in two stroke and rotary engines to increase efficiency and reduce emissions.

How does a Crower steam expansion stroke work?

The Crower steam expansion stroke works by introducing steam into the engine's combustion chamber during the power stroke. The steam expands, pushing against the piston and providing additional power. This allows for better utilization of fuel and a more efficient engine.

What are the advantages of using a Crower steam expansion stroke?

The main advantages of using a Crower steam expansion stroke are increased efficiency and reduced emissions. The use of steam allows for a more complete combustion of fuel, resulting in better fuel economy. It also helps to reduce harmful emissions, making it a more environmentally friendly option.

Are there any drawbacks to using a Crower steam expansion stroke?

One potential drawback of using a Crower steam expansion stroke is the added complexity of the engine design. This can make maintenance and repairs more difficult and expensive. Additionally, the use of steam may require additional equipment and resources, which can add to the cost of the engine.

Is the Crower steam expansion stroke used in any commercial engines?

Currently, the Crower steam expansion stroke is not commonly used in commercial engines. However, it has been tested and used in some prototype engines and is being researched as a potential alternative to traditional engine designs in the future.
