==TWO-STEP CAM CONTROLLED EXHAUST VALVE DEACTIVATION TO OPERATE A DIVIDED EXHAUST BOOST SYSTEM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18059178 titled 'TWO-STEP CAM CONTROLLED EXHAUST VALVE DEACTIVATION TO OPERATE A DIVIDED EXHAUST BOOST SYSTEM

==Simplified Explanation==

The exhaust system described in the patent application includes a unique arrangement of scavenge exhaust valves and blowdown exhaust valves, each controlled by a cam shaft with specific scavenge cams and blowdown cams. The activation and deactivation of these valves are synchronized to optimize the exhaust process in a multi-cylinder engine.

* The exhaust system consists of multiple cylinders, each equipped with scavenge exhaust valves and blowdown exhaust valves.
* A scavenge path and a blowdown path lead from the respective valves to efficiently manage exhaust flow.
* The cam shaft operates scavenge cams and blowdown cams to open and close the valves at precise times during the engine cycle.
* The scavenge exhaust valves and blowdown exhaust valves are activated and deactivated independently for optimal performance.

== Potential Applications ==
The technology described in this patent application could be applied in various internal combustion engines, such as automotive engines, marine engines, and power generators, to improve exhaust gas flow efficiency and overall engine performance.

== Problems Solved ==
This innovation addresses the challenge of effectively managing exhaust flow in multi-cylinder engines, ensuring that the scavenge and blowdown processes are optimized for maximum efficiency and power output.

== Benefits ==
- Enhanced engine performance
- Improved fuel efficiency
- Reduced emissions
- Increased power output

== Potential Commercial Applications ==
The technology could be utilized in the automotive industry, marine industry, and power generation sector to enhance the performance and efficiency of internal combustion engines.

== Possible Prior Art ==
One possible prior art could be the use of variable valve timing systems in engines to optimize exhaust flow, but the specific arrangement of scavenge and blowdown exhaust valves controlled by separate cams may be a novel aspect of this innovation.

=== Unanswered Questions ===

The article does not discuss the cost factors associated with integrating this exhaust system into different types of engines. Understanding the cost implications could be crucial for assessing the feasibility of widespread adoption of this technology.


==Original Abstract Submitted==

An exhaust system includes a plurality of cylinders, and each cylinder includes a scavenge exhaust valve and a blowdown exhaust valve. A scavenge path leads from the scavenge exhaust valves and a blowdown path leads from the blowdown exhaust valves. An arrangement activates and deactivates the scavenge exhaust valves and the blowdown exhaust valves. Further included is a cam shaft including a plurality of scavenge cams and a plurality of blowdown cams. During rotation of the cam shaft, the scavenge cams interact with the scavenge exhaust valves to open and close the scavenge exhaust valves when the scavenge exhaust valves are activated. Additionally, during rotation of the cam shaft, the blowdown cams interact with the blowdown exhaust valves to open and close the blowdown exhaust valves when the blowdown exhaust valves are activated, and at different times with respect to the opening and closing of the scavenge exhaust valves.
