APPARATUS AND METHOD FOR ENGINE OF VEHICLE

摘要

A method of improving fuel efficiency and an apparatus for operating a vehicle that performs the method are provided. The apparatus includes a storing unit that stores control plans for a fuel injection system and an intake/exhaust system that optimize responsiveness of an engine for a plurality of driving modes. A catalyst temperature obtaining unit obtains a catalyst temperature and an operation period determining unit determines an operation period of an engine based on rpm of the engine and an amount of fuel consumption. A driving mode determining unit determines any one of the driving modes as a current driving mode based on the catalyst temperature, the operation period, and present time. Additionally, a controller is configured to access a control plan that corresponds to the current driving mode and operate the fuel injection system and the intake/exhaust system based on the control plan corresponding to the current driving mode.

1. An apparatus for controlling an engine of a vehicle, comprising:
a memory configured to store program instructions; and a processor configured to execute the program instructions, the program instructions when executed configured to:
store control plans for a fuel injection system and an intake/exhaust system that optimize responsiveness of an engine for a plurality of driving modes;detect a catalyst temperature using a sensor;determine an operation period of an engine based on revolutions per minute (rpm) of the engine and an amount of fuel consumption;determine any one of the driving modes as a current driving mode based on the catalyst temperature, the operation period, and present time; andaccess a control plan that corresponds to the current driving mode and operate the fuel injection system and the intake/exhaust system based on the control plan that corresponds to the current driving mode.
