Abstract
Methods and systems for starting an engine are provided. A cold-start request to start the engine in a first operating condition associated with a predetermined engine temperature range is obtained. In response to obtaining the cold-start request, an amount of boost fuel to provide to the engine is determined, based on at least one second operating condition of the engine. The engine is started by supplementing a baseline fuel flow to the engine with the amount of boost fuel.
Claims20
A method for starting an engine, comprising:
- obtaining a cold-start request to start the engine in a first operating condition associated with a predetermined engine temperature range;
- in response to obtaining the cold-start request, determining an amount of boost fuel to provide to the engine based on at least one second operating condition of the engine;
- and
- starting the engine by supplementing a baseline fuel flow to the engine with the amount of boost fuel.
A system for starting an engine, comprising:
- a processing unit;
- and
- a non-transitory computer-readable medium having stored thereon instructions which are executable by the processing unit for:
- obtaining a cold-start request to start the engine in a first operating condition associated with a predetermined engine temperature range;
- in response to obtaining the cold-start request, determining an amount of boost fuel to provide to the engine based on at least one second operating condition of the engine;
- and
- starting the engine by supplementing a baseline fuel flow to the engine with the amount of boost fuel.
A method for starting an engine, comprising:
- obtaining a cold-start request to start the engine in a first operating condition associated with a predetermined engine temperature range;
- in response to obtaining the cold-start request, determining an amount of boost fuel to provide to the engine based on at least one second operating condition of the engine;
- generating a signal to cause a baseline fuel flow to the engine to be supplemented with the amount of boost fuel;
- and
- issuing the signal to effect starting of the engine.
