Internal combustion engine e.g. four stroke diesel engine, particle filter regenerating process, involves modifying fuel injection retarding based on difference between effective and theoretical values of exterior factor

摘要

The process involves retarding fuel injection at an angle. An effective value of an exterior factor influencing exhaust gas temperature of an internal combustion engine (1) is found. The retarding of fuel injection is modified with respect to a difference between the effective value and a theoretical value of the exterior factor. The injected fuel quantity is modified to maintain a constant engine torque. The angle is found based on a high dead point and depends on a functioning point of the internal combustion engine. An independent claim is also included for an automobile having a device for regeneration of a particle filter.
