ENGINE SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240191669 titled 'ENGINE SYSTEM

Simplified Explanation: The patent application describes an engine system with a control device that can automatically stop and restart the engine based on temperature and time parameters. The control device manages fuel supply to different cylinders during engine restart to optimize performance.

• The control device acquires engine temperature and time data during automatic engine stop.
• It executes a specific cylinder fuel cut process to stop fuel supply to the first cylinder and supply fuel to the second cylinder during engine restart.
• The control device increases fuel injection amount in the second cylinder based on engine temperature and stop time to enhance performance during the specific cylinder fuel cut process.

Key Features and Innovation: - Automatic engine stop and restart based on temperature and time parameters. - Specific cylinder fuel cut process for optimized fuel supply during engine restart. - Fuel injection amount adjustment in the second cylinder for improved performance during the fuel cut process.

Potential Applications: This technology can be applied in automotive engines to improve fuel efficiency and reduce emissions. It can also be used in hybrid vehicles for better engine management.

Problems Solved: - Efficient engine stop and restart process. - Optimized fuel supply during engine restart. - Enhanced performance during specific cylinder fuel cut process.

Benefits: - Improved fuel efficiency. - Reduced emissions. - Enhanced engine performance.

Commercial Applications: Title: Engine Management System for Enhanced Performance This technology can be commercially used in automotive industry for developing fuel-efficient and environmentally friendly vehicles. It can also be integrated into hybrid vehicles for better engine control and performance.

Prior Art: There are existing engine management systems that focus on fuel efficiency and emissions reduction. However, the specific cylinder fuel cut process described in this patent application appears to be a novel approach to engine optimization.

Frequently Updated Research: Researchers are constantly exploring new ways to improve engine efficiency and performance. Stay updated on the latest advancements in engine management systems for potential enhancements to this technology.

Questions about Engine Management System: 1. How does the control device determine the optimal fuel injection amount in the second cylinder during engine restart? 2. What are the potential challenges in implementing this technology in different types of engines?

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.
