Internal-combustion engine`s e.g. diesel engine, exhaust gas characteristics improving method, involves activating glow plug for predetermined time period after unencumbered predetermined time interval is exceeded

摘要

The method involves determining a change of pedal value by a measuring unit, and determining an actual speed value of an internal-combustion engine e.g. diesel engine, by another measuring unit. A glow plug is activated for a predetermined time period after an unencumbered predetermined time interval is exceeded, if a change of pedal value is largely zero and/or the speed value of the internal-combustion engine is smaller/same of stored speed value. An independent claim is also included for a method for reduction of exhaust gas emissions of an internal-combustion engine.
