Abstract
A system is provided for controlling engine fueling and includes an internal combustion engine, a fuel source, means for delivering fuel from the fuel source to the engine, and a controller configured to control the fuel delivering means according to a first operational mode so that, upon attaining a predetermined operational state of the engine, an amount of fuel delivered to the engine per unit time is kept constant. The system will typically but not necessarily be provided in a vehicle such as a truck or a passenger automobile. A method for controlling engine fueling is also provided.
Claims19
A system for controlling engine fueling, comprising:
- an internal combustion engine;
- a fuel source;
- means for delivering fuel from the fuel source to the engine;
- a transmission arranged to receive power output from the engine and to deliver power to at least one driven wheel;
- and
- a controller configured to control the fuel delivering means according to a first operational mode so that, upon attaining a predetermined operational state of the engine, an amount of fuel delivered to the engine per unit time is kept constant, and configured to control the fuel delivering means according to an initial operation mode before the first operating mode by changing a fuel consumption rate until the predetermined operational state of the engine is attained.
A method for controlling engine fueling, comprising:
- delivering fuel to an engine via a fuel delivering means;
- delivering power output from the engine to a transmission;
- controlling an amount of fuel delivered to the engine in a first operating mode so that, upon attaining a predetermined operational state of the engine, an amount of fuel delivered to the engine per unit time is kept constant;
- and
- in an initial operation mode before the first operating mode, changing a fuel consumption rate until the predetermined operational state of the engine is attained.
