ENGINE SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18514726 titled 'ENGINE SYSTEM

The abstract of the patent application describes an engine system with a control device that can automatically stop and restart the engine. The control device monitors the engine temperature and time during the automatic stop, cuts fuel supply to one cylinder while supplying fuel to another during restart, and adjusts fuel injection amount based on engine temperature and stop time.

  • The control device acquires engine temperature and stop time data
  • Executes a specific cylinder fuel cut process during engine restart
  • Increases fuel injection amount in the second cylinder based on stop time and engine temperature

Potential Applications: - Automotive industry for improved engine efficiency - Energy conservation in vehicles - Environmental benefits by reducing emissions

Problems Solved: - Enhances engine performance and efficiency - Reduces fuel consumption and emissions - Improves overall engine control and operation

Benefits: - Increased fuel efficiency - Reduced emissions - Enhanced engine performance and longevity

Commercial Applications: Title: "Advanced Engine Control System for Improved Efficiency" This technology can be utilized in automotive manufacturing for vehicles aiming to reduce fuel consumption and emissions, appealing to environmentally conscious consumers.

Questions about the technology: 1. How does the control device monitor engine temperature and stop time during automatic engine stop? 2. What are the specific steps involved in the cylinder fuel cut process during engine restart?


Original Abstract Submitted

An engine system includes an engine including first and second cylinders, and a control device configured to execute automatic stop of the engine and restart of the engine. The control device includes an acquisition unit configured to acquire a temperature of the engine and a time during the automatic stop of the engine, a fuel cut control unit configured to execute a specific cylinder fuel cut process for stopping supply of fuel to the first cylinder and for supplying fuel to the second cylinder when there is a request to restart the engine, and an injection amount control unit configured to increase a fuel injection amount in the second cylinder as the time during the automatic stop of the engine is longer and as the temperature of the engine is lower, during execution of the specific cylinder fuel cut process.
