CONTROL METHOD OF VALVE OPENING AND CLOSING FOR AN ENGINE AND A VALVE CONTROL APPARATUS OF THE ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240102423 titled 'CONTROL METHOD OF VALVE OPENING AND CLOSING FOR AN ENGINE AND A VALVE CONTROL APPARATUS OF THE ENGINE
Simplified Explanation
The abstract describes a control method for valve opening and closing in an engine with intake continuous variable valve duration (CVVD) and timing (CVVT) apparatus, as well as exhaust CVVD and CVVT apparatus. The method involves determining a driving region based on engine speed and torque, and then controlling the timing and duration of valve opening and closing according to the driving region.
- The control method involves determining a driving region based on engine speed and torque.
- Valve opening timing, closing timing, and opening duration are controlled based on the driving region.
- The intake valve closing timing is set before bottom dead center (BDC) in all driving regions.
Potential Applications
The technology can be applied in automotive engines to optimize performance and fuel efficiency by precisely controlling valve timing and duration.
Problems Solved
1. Inefficient engine performance due to suboptimal valve timing and duration. 2. Poor fuel efficiency resulting from improper valve control.
Benefits
1. Improved engine performance and power output. 2. Enhanced fuel efficiency and reduced emissions. 3. Precision control of valve timing for various driving conditions.
Potential Commercial Applications
Optimized valve control technology can be utilized in the automotive industry for the development of high-performance engines with improved fuel efficiency.
Possible Prior Art
One possible prior art could be the use of variable valve timing (VVT) systems in engines to optimize performance. However, the specific combination of continuous variable valve duration and timing for both intake and exhaust valves as described in this patent application may be a novel innovation.
Unanswered Questions
How does the control method adapt to changes in driving conditions such as load or temperature?
The abstract does not provide details on how the control method adjusts valve timing and duration in response to varying driving conditions.
Are there any potential drawbacks or limitations to implementing this technology in engines?
The abstract does not mention any potential drawbacks or limitations that may arise from the implementation of this valve control method.
Original Abstract Submitted
a control method of valve opening and closing for an engine of which an intake continuous variable valve duration (cvvd) apparatus and an intake continuous variable valve timing (cvvt) apparatus are provided on the intake side, and an exhaust continuous variable valve duration (cvvd) apparatus and an exhaust continuous variable valve timing (cvvt) apparatus are provided on the exhaust side. the control method includes: determining, by a controller, a driving region among a predetermined plurality of driving regions according to a speed and a torque of the engine; and controlling, by the controller, opening timing, closing timing, and opening duration of each of an intake valve and an exhaust valve according to the driving region of the engine. the intake valve closing (ivc) timing is before a bottom dead center (bdc) in all driving regions.
