POST-INJECTION STRATEGY OPTIMIZATION FOR CABIN COMFORT IN DIESEL-POWERED VEHICLES

摘要

A method of optimizing usage of post-injection strategy for improved cabin comfort in a vehicle includes detecting a set of conditions corresponding to parameters pertaining to the vehicle's hardware components, driving components and operating conditions. If one or more of the set of conditions are satisfied, the method implements the post-injection strategy for the vehicle, for a pre-determined time, if the fuel-oil ratio for the engine of the vehicle is lower than a pre-determined value.

主权项

1. A method for employing post-injection regeneration, to improve cabin comfort in a diesel-powered vehicle, the method comprising:
determining whether vehicle components are capable of providing sufficient heat to provide cabin comfort; determining whether a cabin heating system is receiving sufficient heat to provide cabin comfort; upon determining that the local components are capable of providing sufficient heat to provide cabin comfort and that the cabin heating system is not receiving sufficient heat to provide cabin comfort, initiating post-injection regeneration; and during post-injection regeneration, upon determining that cumulative post-injection regeneration time exceeds a predetermined limit, or that a fuel-oil ratio exceeds a predetermined limit, terminating and disabling post-injection regeneration.
