Abstract
Abstract A cooling system is provided for an air-cooled internal combustion engine, and includes at least a first fan for causing air to flow along a path directly surrounding individual air-cooled cylinders of the engine and a radiator disposed in the air-flow path. A first liquid flows around the exhaust manifold, for cooling the same, and through the radiator which is cooled by the air-flow that has passed around the air-cooled engine cylinders.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
A cooling system for an air-cooled internal combustion engine, comprising: first means for causing air to flow along a path directly surrounding individual cylinders of said engine; a first cooling liquid jacket formed around an exhaust manifold of the engine for enabling a flow of a first cooling liquid around said exhaust manifold to cool a flow of exhaust gas flowing from said engine through said exhaust manifold; and a radiator communicating with said first cooling liquid jacket to receive a flow of a first cooling liquid therefrom; said radiator being disposed to be cooled by said air flow that has passed said individual cylinders of said engine.
Claim 2
Dependent Claim
108 words
A cooling system for an air-cooled internal combustion engine, comprising: first means for causing air to flow along a path directly surrounding individual cylinders of said engine; a first cooling liquid jacket formed around an exhaust manifold of the engine for enabling a flow of a first cooling liquid around said exhaust manifold to cool a flow of exhaust gas flowing from said engine through said exhaust manifold; and a radiator communicating with said first cooling liquid jacket to receive a flow of a first cooling liquid therefrom; said radiator being disposed to be cooled by said air flow that has passed said individual cylinders of said engine.
Claim 3
Dependent Claim
47 words
The engine cooling system as claimed in claim 1, wherein: said first means are disposed downstream of the cylinders in said air flow path for drawing in said air, and said radiator is disposed between said cylinders and said first means for causing said air to flow.
Claim 4
Dependent Claim
29 words
The engine cooling system as claimed in claim 2, wherein: second means for further enabling said air to flow, disposed upstream of the cylinders in said air flow path.
Claim 5
Dependent Claim
24 words
The engine cooling system as claimed in claim 3, wherein: said second means for enabling said cooling air flow is driven by said engine.
Claim 6
Dependent Claim
31 words
The engine cooling system as claimed in claim 1, further comprising: a second cooling liquid jacket provided about said first cooling liquid jacket to convey a second cooling liquid flow therearound.
Claim 7
Dependent Claim
18 words
The engine cooling system as claimed in claim 1, wherein: said radiator is of a horizontal flow type.
Claim 8
Dependent Claim
28 words
The engine cooling system as claimed in claim 1, further comprising: pump means for causing said first cooling liquid to flow between said radiator and said exhaust manifold.
Claim 9
Dependent Claim
25 words
The engine cooling system as claimed in claim 7, wherein: said pump means for causing said first cooling liquid flow is driven by said engine.
Claim 10
Dependent Claim
26 words
The engine cooling system as claimed in claim 1, wherein: a hydraulic motor is provided for driving said first means for causing said air to flow.
Claim 11
Dependent Claim
27 words
The engine cooling system as claimed in claim 1, wherein: said first means for causing said cooling air flow comprises a hydraulic motor driven by said engine.
