Dual Fuel Auto-ignition Engine

摘要

An Internal combustion engine cylinder uses a conventional primary fuel injector in an intake port 13, and an auxiliary fuel injector 17 for supplying an auxiliary fuel into the centre of a combustion chamber 15. The auxiliary fuel will auto-ignite when the mixture of primary fuel and air is compressed. The engine is preferably a four-stroke petrol (gasoline) engine that has no requirement for a spark plug to ignite the fuel-air mixture. The engine may comprise an integral or discrete cylinder head and a monospace combustion chamber. The auxiliary fuel may be diethyl ether. The engine produces reduced heat losses from a centrally produced flame front that propagates from the inside to the outside of the combustion chamber volume.
