Bill,

Here's a question for you - are = you across the=20 HCCI technology - Homogeneous Charge Compression Ignition = Engine?

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

Sounds perfect for the rotary - we = already have the=20 exhaust emissions fuel and air mix with the PP. I guess the difference = between=20 this and detonation is flame front speed and how that's controlled ( = perhaps=20 with the exhaust contamination).

An 1800 cc HCCI engine (in a large=20 sedan) develops 175KW and uses 6.1 Litres per 100Km.
