Abstract: A heat transfer method for an engine is disclosed herein utilizing a heat battery configured to store waste exhaust heat in phase-chase materials for use during a subsequent engine start. By reusing waste exhaust heat in this manner, exhaust emissions may be reduced, and delays in heating the vehicle cabin and other vehicle systems after engine start may be reduced.

Abstract: An engine lubrication system is provided. The engine lubrication system includes an oil pan housing a lubricant, an oil pump having a pick-up tube including an inlet submerged in the lubricant, and a heat pipe assembly including a fluidly sealed heat pipe coupled to the oil pan adjacent to the inlet of the pick-up tube.

Abstract: A method for recovering exhaust heat for an engine is disclosed herein. The method includes reducing a volume of a circulating heat transfer fluid and discharging a heat storage device to heat an engine component. The method further includes distributing the circulating heat transfer fluid to one or more engine systems.

Abstract: A heat recovery system for an engine is disclosed herein utilizing a heat storage unit configured to store waste exhaust heat for subsequent use on engine starts in various systems. In this way, improved system operation can be obtained by re-using such waste heat.

Abstract: An exhaust system for an engine is disclosed herein. The exhaust system includes a catalytic converter, a heat collector downstream from the catalytic converter, and a heat transfer system receiving waste exhaust heat via a thermosyphon evaporator for storage and/or use in a cabin heating system. In this way, waste heat is utilized to provide better cabin heating, particularly at engine cold start.

Abstract: An exhaust system for an engine is disclosed herein. The exhaust system includes a catalytic converter, an exhaust manifold upstream from the catalytic converter, and a heat pipe in thermal contact with the exhaust manifold and atmosphere. The system further includes a phase changing material that passively absorbs heat after catalytic light-off.

Abstract: An air/fuel mixture induction system for an internal combustion engine having a pair of intake valves, an intake air/fuel mixture flow passage communicating with each valve, a primary mask surrounding a portion of the perimeter of one of the intake valves, the air/fuel mixture being directed from the intake valve over the remaining peripheral portion thereof, thereby establishing a swirl motion in the combustion chamber, a secondary bridge mask partially surrounding the other of the pair of intake valves, the secondary bridge mask having an air/fuel mixture flow controlling surface that directs the swirl motion of the air/fuel mixture in the direction of the axis of the cylinder whereby swirl motion progresses in the direction of the axis of the cylinder throughout the combustion chamber.
