A method of forming an integral drain for a heat exchanger is provided. The method includes forming a plurality of passage walls to define a plurality of passages with an additive manufacturing process, each of the passage walls having a non-linear portion. The method also includes integrally forming a drain wall with at least one of the passage walls with the additive manufacturing process to define a drain for each of the plurality of passages, the drain wall located proximate the non-linear portion of each of the plurality of passage walls.

A system for connecting housing elements of a device for heat transfer having a housing with a first housing element and a second housing element which are connectable with one another with face sides oriented toward one another and via a connection under form closure. Housing elements are herein in contact on another with side margins developed in proximity of front faces. The first latching elements are implemented as recesses each with a flat surface oriented in parallel to front face. On an outer side of side margin of first housing element between each first latching element and front face, a shaping is developed protruding from side margin, which comprises on a side facing first latching element a flat surface disposed in the plane spanned by flat surface of first latching element. Flat surfaces of first latching element and the shaping form a contiguous bearing area for second latching element.

A transfer tube for a thermal transfer device can include at least one wall having an inner surface and an outer surface, where the inner surface forms a cavity, where the at least one wall further has a first end and a second end. The first end can be configured to couple to a terminus of a heat exchanger of the thermal transfer device. The second end can be configured to couple to a collector box of the thermal transfer device. At least a portion of the at least one wall can be disposed in a vestibule of the thermal transfer device. The cavity can be configured to simultaneously receive a first fluid that flows from the first end to the second end and a second fluid that flows from the second end to the first end.

The invention involves a system and method for providing a liquid fuel or a liquid and gaseous fuel to a diesel or Otto cycle engine for operation of the engine. The system includes a primary electronic control module (ECM), which monitors engine sensors and contains a first three-dimensional fuel map for the liquid fuel. A second ECM is connected for bi-directional transfer of information to the first ECM, the second ECM contains a second three-dimensional fuel map for delivery of the gaseous fuel through a secondary gaseous fuel injection assembly. The bi-directional communication between the two ECMs while monitoring the engine sensors allows both ECMs to learn an efficient fuel map for delivery of both fuels in the same cycle for improved efficiency, reduction in slip and lower emissions.

A heat exchanger for providing charged air to a vehicle is described. The heat exchanger includes a plurality of heat exchange elements, and at least one passage. The plurality of heat exchange elements is stacked together in between a pair of side plates, and ends of the plurality of heat exchange elements are received in a pair of headers to configure a fluid circuit. The at least one passage is formed in a first heat exchange element amongst the plurality of heat exchange elements, along with the plurality of heat exchange elements and the first heat exchange element is formed above at least few heat exchange elements of the plurality of heat exchange elements.

A heat exchanger includes a housing having a heat exchanger core and a precooling flow structure disposed therein. The heat exchanger core is configured for exchanging heat between a first fluid and a second fluid. The precooling flow structure is coupled to each of the housing and an inlet end of the heat exchanger core with respect to a flow of the first fluid. An interior of the precooling flow structure is configured to convey the first fluid therethrough, The precooling flow structure includes at least one precooling tube extending through the interior of the precooling flow structure with each of the at least one precooling tubes configured to convey the second fluid therethrough in order to precool the first fluid before the first fluid enters the inlet end of the heat exchanger core.

An inlet tank for a charge cooler comprises a manifold portion, a turbocharger inlet port, and a supercharger inlet port. The turbocharger inlet port is in fluid communication with a compressor wheel of a turbocharger and the manifold portion of the inlet tank. An opening is formed in a sidewall of the turbocharger inlet port. The supercharger inlet port is in fluid communication with an electric supercharger and intersects the turbocharger inlet port. The opening formed in the sidewall of the turbocharger inlet port provides fluid communication between the supercharger inlet port and the turbocharger inlet port. A valve element selectively determines when a flow of air from the supercharger inlet port enters the turbocharger inlet port through the opening based on a pressure differential present between the air exiting the compressor wheel of the turbocharger and the air exiting a compression mechanism of the electric supercharger.

A hinged connection device includes first and second tubular components around a main axis which respectively include a first male hinge member provided with an end head shaped as a spherical segment and a second female hinge member provided with a complementary seat receiving movably inside the end head of the first member. The first member is configured to be housed at least partially inside the first component and to be assembled to the second component throughout the second member. The second member is configured to be mounted around the second component and assembled to the first component over the first member such that the two tubular components are assembled together by the reciprocal intersection of the two hinge members.

An intercooler is coupled to an internal combustion engine by a first bracket extending from the intercooler. A grommet is fitted into an attachment hole of the first bracket. The grommet is made of synthetic rubber. A material of the grommet has a lower Young's modulus than a material of the first bracket. The first bracket is coupled to a second head cover and a second cylinder head by the grommet, an upper bolt, and a lower bolt.
