Method for operation of internal combustion engine, involves determining angular acceleration of crankshaft of internal combustion engine, and providing combustion characteristics of fuel

摘要

The method involves determining angular acceleration of a crankshaft of an internal-combustion engine, and providing combustion characteristics of fuel used for the operation of the internal combustion engine on the basis of the angular acceleration. The method involves adjusting ignition point as a function of the certain combustion characteristics.
