- I remember reading, a lot of years ago, that Smokey Yunick was
- experimenting with an engine where the intake air was heated to
- somewhere around 250 degrees Fahrenheit. This engine also had
- a turbocharger which Yunick referred to as a "homogenizer"; it
- produced only about 1-2 PSI boost. He was apparently trying for
- extremely high gas mileage.
-
- Does anyone know whatever became of this?

- Last I heard, which was direct from the mouth of Jeff Smith at Hot
- Rod Magazine was that he (Smokey) sold the patent to one of the big
- three and they were just sitting on it. It then went to someone like
- B&M who is spposedly developing the device further. I remember
- reading about it in HRM a long time ago. Smokey had a Fiero set up
- with this "Hot Air Engine". It made 2hp/cubic inch and got about
- 35-50 MPG. The car really screamed.It seemed like a real cool way to
- make horsepower. I believe the idea of preheating the fuel and
- homogenizing was to create a perfect fuel vapor, which it did.
- Emissions were about as good as you could get. The problem was
- keeping the whole mess operating at a constant temprature.---

- [Best I can tell, this is a scheme to vaporize the fuel beforehand
- and then mix it with air quite similar to how gaseous fuel carburation
- works. The turbo mixes things up and makes up for the loss in pumping
- efficiency caused by heating the air. This is not a new idea. I recently
- ran across the patent drawing for one of the very first liquid fueled
- engine designs. Kerosene was boiled in a container and air was sucked
- through a perforated tube traversing the container. Mixture was
- regulated by how much heat was input to the boiler. A flame got it
- started; thereafter exhaust heat did the job.
-
- I suspect that rather than a "big three" type sitting on the design, that
- is has been rendered obsolete by modern high swirl, stratified charge
- designs. JGD]
