Process for controlling a gaseous blend in a combustion chamber of a two-stroke cycle of an internal combustion engine

A process for controlling a gaseous blend to be combusted in a combustion chamber of a two-stroke cycle internal combustion engine to reach a predetermined state of temperature, pressure, and air/fuel ratio of the gaseous blend at combustion based on a predetermined operating condition of the internal combustion engine, said process comprising the steps of:

• compressing air to be injected into the combustion chamber during at least one of an exhaust operation and a compression operation of a combustion cycle of the internal combustion engine, said compressed air having an air temperature and an air pressure;
• heating an amount of the compressed air into hot compressed air;
• determining a first quantity of the compressed air, a second quantity of fuel, and a third quantity of hot compressed air needed into the combustion chamber to reach the predetermined state of the gaseous blend, the gaseous blend including the compressed air, the hot compressed air, the injected fuel and a predetermined portion of the combusted gaseous blend from a previous combustion cycle;
• and
• injecting the first quantity of the compressed air and the third quantity of hot compressed air into the combustion chamber during the at least one of the exhaust operation and the compression operation, and the second quantity of the fuel into the combustion chamber during at least one of the at least one of the exhaust operation and the compression operation and an expansion operation of the combustion cycle.
