A HCCI engine includes a cylinder block with a cylinder head closing off a cylinder, a power piston slidably contained within the cylinder and a boost, piston for initiating timed combustion of fuel within a combustion chamber. The boost piston is housed within a wall of the combustion chamber such that when the boost piston moves from a base position to an extended position, the heat increase within the combustion chamber is sufficient to cause fuel within the combustion chamber to ignite.

Why it's free to use
- Filed November 9, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 9, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 9, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
