CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240110534 titled 'CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE

Simplified Explanation

The patent application describes a controller for an internal combustion engine that includes a cylinder and a direct injection valve for injecting gaseous fuel into the cylinder. The controller's CPU acquires in-cylinder pressure and supply fuel pressure, and calculates a backflow rate of combustion gas flowing into the direct injection valve from the cylinder during one combustion cycle. The backflow rate is calculated to increase with higher in-cylinder pressure and lower supply fuel pressure.

  • The controller is used for an internal combustion engine with a direct injection valve for gaseous fuel.
  • The CPU acquires in-cylinder pressure and supply fuel pressure, and calculates a backflow rate of combustion gas.
  • The backflow rate increases with higher in-cylinder pressure and lower supply fuel pressure.

Potential Applications

This technology could be applied in the automotive industry for improving the efficiency and performance of internal combustion engines.

Problems Solved

1. Improved control over combustion processes. 2. Reduction of backflow of combustion gas into the direct injection valve.

Benefits

Original Abstract Submitted

a controller is used for an internal combustion engine including a cylinder and a direct injection valve that injects gaseous fuel into the cylinder. a cpu of the controller executes acquisition of an in-cylinder pressure that is a pressure in the cylinder during one combustion cycle and a supply fuel pressure that is a pressure of the gaseous fuel supplied to the direct injection valve, and calculation of a backflow rate that is an amount of combustion gas flowing into the direct injection valve from the cylinder during one combustion cycle of the cylinder. in the calculation of the backflow rate, the cpu calculates the backflow rate such that the backflow rate becomes larger as the in-cylinder pressure increases and the backflow rate becomes larger as the supply fuel pressure decreases.
