A METHOD OF CONTROLLING COMBUSTION OF FUEL IN A MULTI-CYLINDER INTERNAL COMBUSTION ENGINE AND A COMPUTER CONTROL SYSTEM CONFIGURED TO CONTROL COMBUSTION PROCESS IN A MULTI-CYLINDER INTERNAL COMBUSTION PISTON ENGINE

摘要

Invention relates to a method of controlling combustion of fuel in a multi-cylinder internal combustion engine (10), comprising step of –determining a cumulative heat release (Q) from combustion of fuel during successive combustion cycles in a cylinder of the engine, – determining a mean gross heat release rate (Q') from combustion of fuel during successive combustion cycles in the cylinder of the engine, – using the mean gross heat release rate (Q') as feedback to control the combustion in the cylinder of the engine. Invention relates also to a computer control system (100) configured to control combustion process in a multi-cylinder internal combustion piston engine (10).
