Internal combustion engine having exhaust gas bypassing control mechanism

Abstract

[PROBLEMS] To provide an internal combustion engine enabling an increase in engine efficiency and fuel economy and a reduction in residual black smoke concentration of exhaust gas. [MEANS FOR SOLVING PROBLEMS] One end of each of air flow passages is connected to the side wall of the cylinder exhaust tube of each of cylinders, the other end of each of these air flow passages is connected to a shared bypass control chamber, and the exhaust tube of each of the cylinders is connected to each of the flow passages through the shared bypass control chamber. Thus, a part of pressurized exhaust gas in the exhaust tube of each of the cylinders brought in an exhaust step when the other cylinders are in an explosive step is discharged to the bypass control chamber through the air flow passage by the compression explosion compressive pressure of the atmosphere produced as a reaction immediately after an explosion exhaust to absorb an exhaust resistance. On the AS other hand, a part of a surplus pressure gas in the bypass control chamber is sent to the other cylinder exhaust tubes through the other air flow passages, and a fuel and an air in the exhaust gas are uniformly mixed with each other in an entire bypass step and re-burned for complete combustion.

1 . An internal combustion engine having a plurality of engine cylinders conducting piston operation at a predetermined time lag and a common exhaust cylinder in communication with an exhaust tube for each of the engine cylinders, in which one end of an air flow passage is in communication with a cylinder exhaust tube for each of the cylinders of an engine main body, the other end of each of the air flow passages is in communication with a common bypassing control chamber, the cylinder exhaust tubes are in communication to each other by way of each of the air flow passages and the common bypassing control chamber, whereby an implosive compression pressure of an atmospheric air from the exhaust cylinder generated as reaction just after the explosive exhaustion delivers, a portion of a pressurized exhaust gas in the cylinder exhaust tube that conducts an exhaustion step during the explosive step of other cylinder by way of the air flow passage to the bypassing control chamber, and a portion of a surplus pressure gas in the bypassing control chamber is sent out by way of other air flow passage to a cylinder exhaust tube under the state of a low pressure. 
   
   
       2 . An internal combustion engine according to  claim 1 , wherein each of the cylinder exhaust tubes in communication with each of the cylinder exhaust ports of the engine main body, an air flow passage branched from each of the exhaust tubes, a common bypassing control chamber in communication with each of the air flow passages, and a common exhaust cylinder connection port in communication with each of the cylinder exhaust tubes are formed in an integral casing, and they are joined to the engine main body such that each of the cylinder exhaust tubes and each of the cylinder exhaust ports are in communication with each other. 
   
   
       3 . An internal combustion engine according to  claim 1 , wherein an air injection means having a check valve that opens to the side of the control chamber is disposed to the common bypassing control chamber. 
   
   
       4 . An internal combustion engine according to  claim 1 , wherein an alkali ingredient injection means having a check valve that opens to the side of the control chamber is disposed to the common bypassing control chamber. 
   
   
       5 . An internal combustion engine according to  claim 2 , wherein an air injection means having a check valve that opens to the side of the control chamber is disposed to the common bypassing control chamber. 
   
   
       6 . An internal combustion engine according to  claim 2 , wherein an alkali ingredient injection means having a check valve that opens to the side of the control chamber is disposed to the common bypassing control chamber. 
   
   
       7 . An internal combustion engine according to  claim 3 , wherein an alkali ingredient injection means having a check valve that opens to the side of the control chamber is disposed to the common bypassing control chamber.
