Title:
4行程自己点火エンジン
Document Type and Number:
Japanese Patent JP4176483
Kind Code:
B2
Abstract:
A method of operating a four stroke internal combustion engine comprising the steps of using inlet valve means (15) to regulate admission of a mixture of fuel and air into a combustion chamber (12), using a compressor (151) to compress the fuel and air mixture prior to admission of the mixture into the combustion chamber (12), using exhaust valve means (16) to regulate flow of combusted gases from the combustion chamber (12), closing the exhaust valve means (16) prior to the end of the exhaust stroke to trap combusted gases in the combustion chamber (12), opening the inlet valve means (15) during the intake stroke to admit a charge of fuel and air mixture into the combustion chamber (12) to be mixed with the previously trapped combusted gases, whereby in the combustion chamber (12) conditions are generated which enable the mixture of fuel, air and combusted gases to combust by auto-ignition, with the combusted gases expanding during the power stroke.
By opening the inlet valve means (15) to admit a preconditioning charge of fuel and air into the combustion chamber (12) to be mixed with the trapped combusted gases after closing of the exhaust valve means (16) during the exhaust stroke and prior to the opening of the inlet valve means (15) in the induction stroke to admit the charge of fuel and air which is combusted to expand in the power stroke.
