Abstract
A cooling apparatus for an integrated exhaust manifold includes: a first cooling jacket configured to surround a portion of an exhaust manifold; and a second cooling jacket configured to surround another portion of the exhaust manifold. The first cooling jacket includes a first portion sitting atop the second cooling jacket and a second portion adjacent the second cooling jacket and positioned lower than the first portion.
Claims17
A cooling apparatus for an integrated exhaust manifold, comprising:
- a first cooling jacket surrounding a portion of an exhaust manifold;
- a second cooling jacket surrounding another portion of the exhaust manifold;
- the first cooling jacket including a first portion sitting atop the second cooling jacket and a second portion adjacent the second cooling jacket and positioned lower than the first portion;
- and
- a plurality of cooling lines running between the first and second cooling jackets.
A cooling system for an internal combustion engine with an integrated exhaust manifold, comprising:
- a cylinder head assembly having:
- (i) a first cooling jacket configured to surround a portion of an exhaust manifold;
- (ii) a second cooling jacket configured to surround another portion of an exhaust manifold;
- and
- (iii) a plurality of cooling lines running between the first and second cooling jackets;
- and
- a pump fluidically connected to the cylinder head assembly, wherein the cooling system is configured to flow coolant from the first cooling jacket to the second cooling jacket and into an engine block.
A method of manufacturing a cooling system for an internal combustion engine with an integrated exhaust manifold, comprising:
- forming a cylinder head assembly having a first cooling jacket and a second cooling jacket, at least partially surrounding the exhaust manifold;
- forming a plurality of cooling lines running between the first and second cooling jackets;
- connecting a pump to the first or second cooling jacket;
- forming the first cooling jacket to include a first portion sitting atop the second cooling jacket;
- and
- forming the first cooling jacket to include a second portion adjacent the second cooling jacket and positioned lower than the first portion so that a cooling line formed in the second portion of the first cooling jacket meters coolant from the lower cooling jacket to the upper cooling jacket.
