Engine management system and method

A method for controlling an internal combustion engine, the method comprising the steps of:

• providing an internal combustion engine comprising at least one piston including at least one micro-chamber and corresponding vent;
• providing a control system;
• providing at least one sensor in communication with the internal combustion engine and the control system;
• receiving by the control system one or more readings from the at least one sensor;
• receiving by the control system one or more operational parameters of the internal combustion engine,
• wherein the one or more readings and the one or more operation parameters are indicative of a determinable in-cylinder temperature and an equivalence ratio;
• determines the in-cylinder temperature and the equivalence ratio;
• controlling by the control system an operation of the internal combustion engine;
• and
• based on the controlled operation of the internal combustion engine, determining whether a global low-temperature decomposition chemical combustion reaction occurs within at least one cylinder of the internal combustion engine
• wherein the global low-temperature decomposition chemical reaction occurs
• at a temperature within a range of greater than or equal to 600 K and less than or equal to 1000 K, and
• at an equivalence ratio within a range of greater than or equal to 0.06 and less than or equal to 2.0.

An engine management system comprising:

• an internal combustion engine including at least one piston comprising at least one micro-chamber and a corresponding vent and
• a control system,
• wherein the control system
• receives one or more readings from one or more sensors arranged on or in the internal combustion engine;
• receives one or more operational parameters of the internal combustion engine,
• wherein the one or more readings and the one or more operation parameters are indicative of a determinable in-cylinder temperature and an air/fuel ratio;
• determines the in-cylinder temperature and the air/fuel ratio;
• controls an operation of the internal combustion engine;
• and
• based on the controlled operation of the internal combustion engine, determines whether a global low-temperature decomposition chemical combustion reaction occurs within at least one cylinder of the internal combustion engine,
• wherein the global low-temperature decomposition chemical reaction occurs
• at a temperature within a range of greater than or equal to 600 K and less than or equal to 1000 K, and
• at an air/fuel ratio within a range of greater than or equal to 26.5 and less than 30:1.
