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 CDA (Camshaft Driven Actuator) operation interlocked oil jet system for an engine. The system includes an OCV (Oil Control Valve) that supplies oil for the operation of the rocker arm, and an oil jet check valve that injects oil towards the engine piston through a bypass oil extension line. The system also includes a control unit that controls the OCV to open the bypass oil extension line when the CDA is operated.

  • The system connects the OCV and the oil jet check valve to enable oil jet injection towards the engine piston.
  • The control unit controls the OCV to open the bypass oil extension line when the CDA is operated.
  • The bypass function of the OCV is divided into the operation and non-operation of the CDA, allowing control over the oil jet injection.
  • Oil jet injection to the cylinder occurs when the CDA is not operated, and is stopped in the deactivated cylinder when the CDA is operated.
  • This prevents the oil-up phenomenon and reduces the capacity of the oil pump by reducing or blocking unnecessary injection oil.

Potential Applications

  • Automotive industry: This technology can be applied to internal combustion engines in vehicles to improve oil injection control and reduce oil pump capacity.

Problems Solved

  • Oil-up phenomenon: By controlling the oil jet injection and stopping it in the deactivated cylinder, this technology prevents excessive oil accumulation and potential engine damage.
  • Oil pump capacity: By reducing or blocking unnecessary oil injection, the capacity of the oil pump can be reduced, leading to energy savings and improved efficiency.

Benefits

  • Improved oil injection control: The system allows precise control over oil jet injection, preventing oil-up phenomenon and potential engine damage.
  • Energy savings: By reducing the capacity of the oil pump, this technology helps in saving energy and improving overall efficiency.


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.
