SYSTEM AND METHOD FOR CONTROLLING ENGINE

摘要

A control system of an engine is provided. The control system includes an inlet sensor configured to generate a signal indicative of an engine inlet air temperature and an intake manifold sensor configured to generate a signal indicative of an engine intake manifold air temperature. The control system includes a control module communicably coupled to the inlet sensor and the intake manifold sensor. The control module is configured to determine the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine an initial de-rate value based on a predetermined relationship between the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine a pre-stored de-rate modifier corresponding to an engine speed. The control module is configured to determine a final de-rate value based on the initial de-rate value and the pre-stored de-rate modifier.

1. A control system of an engine, the control system comprising:
at least one inlet sensor configured to generate a signal indicative of an engine inlet air temperature; at least one intake manifold sensor configured to generate a signal indicative of an engine intake manifold air temperature; and a control module communicably coupled to the at least one inlet sensor and the at least one intake manifold sensor, the control module configured to:
determine the engine inlet air temperature and the engine intake manifold air temperature based on the signals;determine an initial de-rate value based on a predetermined relationship between the engine inlet air temperature and the engine intake manifold air temperature;determine a pre-stored de-rate modifier corresponding to an engine speed; anddetermine a final de-rate value based on the initial de-rate value and the pre-stored de-rate modifier.
