Internal combustion engine with cooling circuit

An internal combustion engine, comprising:

• an engine block having a combustion cylinder, an air intake port in communication with said combustion cylinder, and an exhaust port in communication with said combustion cylinder;
• a piston reciprocatingly disposed in said combustion cylinder;
• an air intake tube in communication with said air intake port;
• an exhaust tube in communication with said exhaust port;
• a heat transfer circuit having a first section disposed about said exhaust tube, a second section defining a heat transfer area, a heat transfer agent disposed within said heat transfer circuit, and a one-way flow valve;
• and
• a cooling circuit having a first portion in thermal transfer relationship with said second section of said heat transfer circuit, a second portion disposed about said air intake tube, a refrigerant disposed within said cooling circuit, and an orifice between said first portion and said second portion upstream of said second portion.

An internal combustion engine, comprising:

• an engine block with a combustion cylinder therein, an air intake port in communication with the combustion cylinder, and an exhaust port in communication with the combustion cylinder;
• a piston reciprocatingly disposed in the combustion cylinder;
• an exhaust stack in communication with the exhaust port;
• a first thermal transfer circuit having ammonia therein and including a heat receiving coil disposed about said exhaust stack, a one-way valve, and a heat transfer section;
• and
• a second thermal transfer circuit having a refrigerant therein and including a cooling coil, an orifice disposed upstream of said cooling coil, and a heat absorption section upstream of said orifice, said heat absorption section in thermal transfer relationship with said heat transfer section, wherein said refrigerant is adapted to produce cooling in said cooling coil.

In an internal combustion engine having an engine block with at least one combustion cylinder, an air intake port in communication with each combustion cylinder, an air intake tube in communication with each air intake port, an exhaust port in communication with each combustion cylinder, a piston reciprocatingly disposed within each combustion cylinder, and an exhaust stack in communication with each exhaust port, a method of cooling intake air comprising:

• providing a heat transfer system having a circuit tube with a first portion in heat transfer relationship with the exhaust stack for receiving heat from the exhaust stack and a second portion defining a heat conduction area to liberate heat, a heat transfer agent within the circuit tube to transfer heat received at the first portion to the second portion by flowing within the circuit tube, and a flow valve in the circuit tube to control the flow of the heat transfer agent;
• and
• providing a cooling system having a circuit conduit with a first section defining a heat receiving area in thermal contact with the heat conduction area of the heat transfer system for receiving heat from the heat transfer system and a second section defining a cooling area in cooling relationship with the air intake tube for cooling the air within the air intake tube, a refrigerant within the circuit conduit for receiving heat from the heat receiving area to cause the refrigerant to compress into a liquid and flow within the circuit conduit, and a restriction in the circuit conduit between the first section and the second section upstream of the second section to cause the refrigerant to evaporate into a gas and provide cooling in the second section.
