Abstract

Disclosed is a manifold coupled to at least one cylinder of a diesel engine through at least one valve to pass or block gas flow between said manifold and said cylinder, with a specific list of restrictions imposed on said flow. Also, a manifold coupled to at least a pair of the cylinders of a multi-cylinder diesel engine through at least one valve to pass or block gas flow between said manifold and said cylinder, with the same restrictions imposed on said flow. The so formed structure is suitable to CGR.

Claims

exact text as granted — not AI-modified
1 . Manifold coupled to at least one cylinder of a diesel engine through at least one valve to pass or block gas flow between said manifold and said cylinder, with all the following concurrent restrictions imposed on said flow: a) any other gas flow between said cylinder and any other place is blocked, b) outflow out of said cylinder is blocked when the pressure in said cylinder is rising and furthermore when the pressure in said cylinder is higher than in said manifold and furthermore during the larger part of said pressure rising, c) inflow into said cylinder is blocked when the pressure in said cylinder is falling and furthermore when the pressure in said cylinder is lower than in said manifold and furthermore during the larger part of said pressure falling. 
     
     
         2 . Manifold coupled to at least a pair of the cylinders of a multi-cylinder diesel engine through at least one valve to pass or block gas flow between said manifold and said cylinder, with all the following concurrent restrictions imposed on said flow: a) any other gas flow between said cylinder and any other place is blocked, b) outflow out of said cylinder is blocked when the pressure in said cylinder is rising and furthermore when the pressure in said cylinder is higher than in said manifold and furthermore during the larger part of said pressure rising, c) inflow into said cylinder is blocked when the pressure in said cylinder is falling and furthermore when the pressure in said cylinder is lower than in said manifold and furthermore during the larger part of said pressure falling. 
     
     
         3 . Manifold as per  claim 1  having means to dump gas when said flow is blocked. 
     
     
         4 . Manifold as per  claim 2  having means to dump gas when said flow is blocked. 
     
     
         5 . Manifold as per  claim 1 , whereas said valve is cam operated. 
     
     
         6 . Manifold as per  claim 2 , whereas said valve is cam operated. 
     
     
         7 . Manifold as per  claim 1 , whereas said valve is electronically controlled. 
     
     
         8 . Manifold as per  claim 2 , whereas said valve is electronically controlled. 
     
     
         9 . Manifold as per  claim 1 , whereas said valve is an internally piloted pneumatic valve. 
     
     
         10 . Manifold as per  claim 1 , whereas said valve is an externally piloted pneumatic valve. 
     
     
         11 . Manifold as per  claim 1 , whereas said valve is a hydraulic valve. 
     
     
         12 . Manifold as per  claim 2 , whereas said valve is an internally piloted pneumatic valve. 
     
     
         13 . Manifold as per  claim 2 , whereas said valve is an externally piloted pneumatic valve. 
     
     
         14 . Manifold as per  claim 2 , whereas said valve is a hydraulic valve.
