ABSTRACT:
An engine charge control system operates by initially reducing power from full load by retarding exhaust valve closing timing to increase exhaust gas charge dilution up to the limit for efficient operation. Further load reductions are made by reducing charge mass without increased dilution via alternative steps such as throttling (in conjunction with intake check valves or using individual cylinder valves) or retarding intake valve opening timing without throttling. Partial substitution of external charge dilution is also contemplated.
