Characteristic parameter e.g. mass of air, estimating method for e.g. diesel engine, involves controlling thermal flux applied to component e.g. piston, of engine in closed loop, from derived magnitude of estimated characteristic parameters

摘要

The method involves estimating determined parameters e.g. value of mass of fuel, injected in a combustion chamber of each of cylinders (1a-1d), value of mass of air mixture and exhaust gas recirculation at an intake pipe (310) of a thermal engine (3), and temperature of the mixture, and magnitude of combustion phasing in a combustion cycle. Thermal flux applied to a component e.g. piston or actuator, of the thermal engine is controlled in a closed loop, from the derived magnitude of the estimated characteristic parameters.
