Method of controlling the timing of ignition in an internal combustion engine

The method of controlling the timing of ignition in an internal combustion compression engine comprising cylinders, reciprocating pistons, a supply of fuel and air to such cylinders, and wherein said engine has a predetermined maximum operating power capability and a predetermined idling power setting, comprising, introducing combustible fuel into said cylinders, compressing said fuel to combust the same,

• determining the conditions of temperature and pressure within at least one of said cylinders at a time period in the engine cycle when the engine is operating at the predetermined ignition timing conditions which are sought to be maintained;
• said time period being during the time when conditions of temperature and pressure within the cylinder are at less than maximum, and when said engine is operating at between its maximum power capability but at greater than its idling power setting,
• intermittently monitoring the conditions of temperature and pressure within said cylinder at the same time period in the engine cycle as said foregoing time period during operation of said engine,
• introducing air under pressure into said cylinder during an intake portion of the cycle of said piston within said cylinder,
• and restoring the predetermined conditions of temperature and pressure to said cylinder when variations in temperature and pressure are detected during said monitoring by adjusting the pressure of air introduced into said cylinder during said intake portion of the cycle of said piston without adjusting the pressure of fuel introduced into said cylinder during said intake portion of the cycle of said piston.
