Abstract
An internal combustion engine combustion system, including an ignition element and an ignition actuation member. The ignition element is configured to ignite an air-fuel mixture compressed within a combustion chamber of an internal combustion engine. The ignition actuation member is movable between a first position in which the ignition actuation member prevents ignition of the air-fuel mixture when present in the combustion chamber, and a second position in which the ignition actuation member permits ignition of the air-fuel mixture by exposing the ignition element to the air-fuel mixture when the air-fuel mixture is present in the combustion chamber.

An internal combustion engine combustion system, comprising:
- an ignition element configured to ignite an air-fuel mixture compressed within a combustion chamber of an internal combustion engine;
- and
- an ignition actuation member movable between a first position in which the ignition actuation member prevents ignition of the air-fuel mixture when present in the combustion chamber, and a second position in which the ignition actuation member permits ignition of the air-fuel mixture by exposing the ignition element to the air-fuel mixture when the air-fuel mixture is present in the combustion chamber.
An internal combustion engine combustion system, comprising:
- an ignition surface configured to be heated to a temperature sufficient to create an ignition element to ignite an air-fuel mixture compressed within a combustion chamber of an internal combustion engine;
- an ignition actuation member movable between a first position in which the ignition actuation member prevents ignition of the air-fuel mixture when present in the combustion chamber, and a second position in which the actuation member permits ignition of the air-fuel mixture by exposing the ignition element to the air-fuel mixture when the air-fuel mixture is present in the combustion chamber;
- an isolation member seals the ignition surface within an isolation cavity in the first position;
- and
- an actuating device configured to move the ignition actuation member between the first and second positions.
A method of operating an internal combustion engine, the method comprising:
- moving an ignition actuation member from a first position, in which the ignition actuation member prevents ignition of an air-fuel mixture present in a combustion chamber of an internal combustion engine by preventing exposure of an ignition element to the air-fuel mixture therein, to a second position in which the ignition actuation member permits ignition of the air-fuel mixture by permitting exposure of the ignition element to the air-fuel mixture;
- and
- returning the ignition actuation member to the first position after ignition of at least a portion of the air-fuel mixture.
