A second reply to the same post. I Went to the Sandia combustion labs. A US department of energy lab. Their comments on the technology are as mentioned before either high compression or intke heating are required. Supercharging or intake is also a way to high cylinder pressure. Right now they say that the trouble for the tech is controling the timing event. They say the system works well but doesn't transition to high load well. Right now another hopeful technology that's not ready quite yet.

Bill,

Here's a question for you -?are you across the HCCI technology - Homogeneous Charge Compression Ignition Engine?

?

These engine combine the advantages of a petrol and diesel engines, whereby a mixture of petrol air and recycled exhaust are ignited spontaneously as in a diesel engine, resulting in lower peak temp, low nitrous oxide emissions and a 15 to 20 increase in fuel economy. I don't know if they use spark plugs - I'm guessing NOT.

?

Sounds perfect for the rotary - we already have the exhaust emissions fuel and air mix with the PP. I guess the difference between this and detonation is flame front speed and how that's controlled ( perhaps with the exhaust contamination).

?

An 1800 cc HCCI engine (in a large sedan)?develops 175KW and uses 6.1 Litres per 100Km.

George (down under)
