ENGINE COOLING SYSTEM

A cooling jacket is formed at least in part within the cylinder head mounted on an engine block defining one or more piston cylinders and one or more intake and exhaust ports in communication with each piston cylinder. The cooling jacket includes a first passageway, a second passageway and a turbulence chamber. The first passageway extends from a first flow passage and intersects the turbulence chamber at a first angular position, and the second passageway extends from a second flow passage and intersects the turbulence chamber at a second angular position different from the first angular position. A swirling action is imparted to fluid media passing through the turbulence chamber. 1. In an engine having an engine block and a cylinder head mounted on the engine block defining one or more piston cylinders and one or more intake and exhaust ports in communication with each piston cylinder , a cooling jacket formed at least in part within the head , comprising:a first passageway;a second passageway; anda turbulence chamber disposed about a chamber axis, the turbulence chamber having a first inlet opening at a first angular position, a second inlet opening at a second angular position different from the first angular position, and an outlet opening positioned about the chamber axis;wherein the first passageway extends from a first flow passage and intersects the turbulence chamber at the first inlet opening and the second passageway extends from a second flow passage and intersects the turbulence chamber at the second inlet opening;whereby at the turbulence chamber a swirling action is imparted to fluid media exiting the turbulence chamber through the outlet opening.2. The cooling jacket of claim 1 , wherein the first flow passage is a first coolant inlet and the second flow passage is a second coolant inlet claim 1 , andwherein a first coolant stream from the first coolant inlet flows through the first passageway into the turbulence chamber from a first direction and a ...

CYLINDER HEAD WITH IMPROVED VALVE BRIDGE COOLING

The cylinder head also includes a first runner defined by the body and open to the fire deck to at least partially form a first valve seat, a second runner defined by the body and open to the fire deck to at least partially form a second valve seat, and a channel defined by the body, where the cooling channel is in fluid communication with the water jacket and positioned between the first runner and the second runner, and where the cooling channel includes a flow diverter configured to produce a turbulent region proximate the fire deck. 1. A cylinder head for use with an internal combustion engine , the cylinder head comprising:a body having a fire deck and defining a water jacket in fluid communication with a cooling system;a first runner defined by the body and open to the fire deck to at least partially form a first valve seat;a second runner defined by the body and open to the fire deck to at least partially form a second valve seat;a channel defined by the body, where the cooling channel is in fluid communication with the water jacket and positioned between the first runner and the second runner, wherein the cooling channel includes an interior surface defining a surface angle between approximately 45 degrees and approximately 90 degrees in at least one location.2. The cylinder head of claim 1 , wherein the interior surface includes a first portion adjacent to the fire deck and a second portion opposite the first portion claim 1 , and wherein the second portion of the interior surface defines a surface angle between approximately 45 degrees and approximately 90 degrees in at least one location.3. The cylinder head of claim 2 , wherein the first portion of the interior surface and the fire deck share a common wall.4. The cylinder head of claim 3 , wherein the common wall ...

CYLINDER HEAD WITH IMPROVED VALVE BRIDGE COOLING

A cylinder head for use with an internal combustion engine, the cylinder head including a body having a fire deck and defining a water jacket in fluid communication with a cooling system, a first runner defined by the body and open to the fire deck to at least partially form a first valve seat, a second runner defined by the body and open to the fire deck to at least partially form a second valve seat, and a channel defined by the in fluid communication with the water jacket and positioned between the first runner and the second runner. The channel, in turn, includes a first inlet through which a first flow enters the channel, a second inlet through which a second flow enters the channel, and where the first inlet and the second inlet are oriented such that the first flow and the second flow interact with one another to create a turbulent region within the channel. 1.
