CDA OPERATION-INTERLOCKED OIL JET SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17978499 titled 'CDA OPERATION-INTERLOCKED OIL JET SYSTEM

Simplified Explanation

The abstract describes a system for controlling the oil jet injection in an engine using a CDA (Camshaft Driven Actuator) operation. The system includes an interlocked oil jet system that connects the OCV (Oil Control Valve) and the oil jet check valve. A control unit is used to control the OCV and the bypass oil extension line.

  • The system connects the OCV and the oil jet check valve to control the oil jet injection in the engine.
  • The control unit is responsible for controlling the OCV and the bypass oil extension line.
  • The bypass oil extension line is opened when the CDA is operated, allowing for control of the oil jet injection.
  • The system divides the bypass function of the OCV based on the operation and non-operation of the CDA.
  • The oil jet injection is performed when the CDA is not operated and stopped in the deactivated cylinder when the CDA is operated.
  • This system helps prevent the oil-up phenomenon and reduces the capacity of the oil pump by reducing or blocking unnecessary injection oil.

Potential Applications:

  • Automotive industry
  • Engine manufacturing companies

Problems Solved:

  • Prevents oil-up phenomenon
  • Reduces capacity of the oil pump
  • Controls oil jet injection in the engine

Benefits:

  • Improved engine performance
  • Reduced oil consumption
  • Cost savings in oil pump capacity


Original Abstract Submitted

A CDA operation interlocked oil jet system connects the OCV for supplying the oil for the operation of the CDA of the rocker arm and the oil jet check valve configured to perform the oil jet injection toward the piston of the engine by the bypass oil extension line, and includes the control unit configured to control the OCV so that the bypass oil extension line is open when the CDA is operated, so that it is possible to control the oil jet injection by dividing the bypass function of the OCV into the operation and non-operation of the CDA to use the bypass function of the OCV accordingly, and in particular, the oil jet injection to the cylinder is performed when the CDA is not operated, and then stopped in the deactivated cylinder that occurs when the CDA is operated, so that it is possible to prevent the oil-up phenomenon and reduce the capacity of the oil pump by reducing or blocking the unnecessary injection oil of the oil jet.
