Abstract
Abstract An internal combustion engine includes a fuel activation chamber (3) disposed near a main combustion chamber (2) and a valve (13) disposed between the fuel activation chamber and the main combustion chamber to open and close therebetween. The valve is opened by movement of a valve body (10) thereof to the fuel activation chamber. Further, there is provided a valve control device which controls to open and close the valve at the ignition timing in a low speed operation and controls to maintain the valve open in a medium and high speed operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
56 words
An internal combustion engine including a fuel activation chamber disposed near a main combustion chamber and a valve disposed between the fuel activation chamber and the main combustion chamber to open and close therebetween, characterized in that said valve is opened by movement of a valve body of said valve to said fuel activation chamber side.
Claim 2
Dependent Claim
56 words
An internal combustion engine including a fuel activation chamber disposed near a main combustion chamber and a valve disposed between the fuel activation chamber and the main combustion chamber to open and close therebetween, characterized in that said valve is opened by movement of a valve body of said valve to said fuel activation chamber side.
Claim 3
Dependent Claim
21 words
An internal combustion engine according to Claim 1, characterized in that an ignition plug is exposed in said fuel activation chamber.
Claim 4
Dependent Claim
82 words
An internal combustion engine according to Claim 1, characterized in that a fuel feeding hole from which fuel is injected into said fuel activation chamber and a compressed air introducing hole for leading the compressed air from said main combustion chamber into said fuel activation chamber are joined each other at respective intermediate positions so that the compressed air from said main combustion chamber and fuel injected from a fuel injection nozzle are premixed to be injected into said fuel activation chamber.
Claim 5
Dependent Claim
120 words
An internal combustion engine according to Claim 1, characterized in that said fuel activation chamber is formed in a holder formed separately from a cylinder head and a hole provided with a step at a substantially central portion thereof and into which said holder is fitted is formed in said cylinder head eccentrically with respect to said main combustion chamber to an extent that part of said hole overlaps an inner periphery of a cylinder block, said holder being formed with a step corresponding to the step of said hole, said holder being fixed by the step of said hole of said cylinder head and the inner periphery of said cylinder block when said holder is fitted into said hole.
Claim 6
Dependent Claim
69 words
An internal combustion engine including a fuel activation chamber disposed near a main combustion chamber and a valve disposed between said fuel activation chamber and said main combustion chamber to open and close therebetween, characterized by the provision of valve control means for opening and closing said valve at an ignition timing in a low speed operation and maintaining said valve open in a medium and high speed operation.
Claim 7
Dependent Claim
69 words
An internal combustion engine including a fuel activation chamber disposed near a main combustion chamber and a valve disposed between said fuel activation chamber and said main combustion chamber to open and close therebetween, characterized by the provision of valve control means for opening and closing said valve at an ignition timing in a low speed operation and maintaining said valve open in a medium and high speed operation.
Claim 8
Dependent Claim
30 words
An internal combustion engine according to Claim 5, characterized in that said valve is opened by movement of a valve body of said valve to said fuel activation chamber side.
Claim 9
Dependent Claim
136 words
An internal combustion engine according to Claim 1, characterized by the provision of valve body adjusting means for shifting said valve body in a radial direction or an axial direction thereof in accordance with an operation condition, a pair of notches formed in said valve body and a valve seat of said valve, respectively, and which are overlapped each other in accordance with a shifted amount of said valve body by said valve body adjusting means, and a compressed air injection hole formed in said valve by the overlap of said pair of notches to inject the compressed air in said main combustion chamber into said fuel activation chamber so that the compressed air of an amount in accordance with said operation condition is introduced into said fuel activation chamber through said compressed air injection hole.
