Intake pipe (6) for an internal combustion engine (1) supercharged by means of a turbocharger (12) provided with a turbine (13) and a supercharger (14); wherein at least a segment (47) of the intake pipe (6) is provided with a thermoelectric conversion device (53) comprising a number of Peltier coolers (54) and designed to exploit the heat of the air flow exiting the supercharger (14); and wherein the segment (47) of the intake pipe (6) is provided with an inner jacket (52) coaxial with the segment (47) itself, wherein the inner jacket (52) comprises a plurality of Peltier coolers (54) comprising a hot side thermally coupled to a surface delimiting the hot zone from which to extract heat in the area of said segment (47).
摘要:
The present invention relates to a device for controlling the quantity of air admitted to a supercharged internal combustion engine, said engine comprising two exhaust gas outlets (32, 36) each connected to an exhaust manifold (30, 34) of a bank of at least one cylinder (121, 122, 123, 124), said device comprising a supercharging device (38) comprising a turbocharger with a turbine (40) with two inlets (50, 52) connected to said exhaust gas outlets and an external-air compressor (44), and a transfer pipe (64) for the partial transfer of the compressed air from the compressor to the inlets of the turbine. According to the invention, the partial transfer pipe comprises two branches (70, 72) which are connected to the inlets of the turbine and each bear throttling means (74, 76) controlling the circulation of the compressed air in these branches.
摘要:
A thermal fuel delivery system includes an insertion assembly and a fuel device. The insertion assembly includes a housing defining a cavity for housing the fuel device. The housing is disposed above and coupled to a pair of frame members via a plurality of connecting members. The frame members extend laterally away from the housing. The insertion assembly further includes an intake manifold coupled to the housing via a tube. A plurality of runner tubes extend laterally away from the intake manifold and pass through the frame members at an inner portion of the frame members and terminate at an outer portion of the frame members.

An intake air supply construction for an engine includes an intake pipe 6 through which intake air flows, an intake manifold 2 that is connected to the intake pipe 6 so as to induce intake air into a plurality of intake ports that are aligned in a cylinder head, an intercooler 15 that is incorporated in the intake manifold 2 so as to cool intake air, and a lid 26A that closes, from an exterior, a working opening portion 24 that is formed in a side surface portion 23a of the intake manifold 2 that lies upstream of the intercooler 15 in relation to the flow of intake air. The intake manifold 2 has a boss portion 25 to which the lid 26A is fastened. The boss portion 25 projects from an inner surface of the side surface portion 23a that faces an outlet 34 side, so as to divide intake air that flows in from an inlet 21 to both sides of an aligning direction of the intake ports.
摘要:
Various methods and systems are provided for an intake manifold for an engine. In one example, an insert comprises an annular body having a top surface, bottom surface, inner surface, and outer surface. The insert further comprises a first groove for coupling an intake air port of an intake manifold to a cylinder head, a second groove for circulating gaseous fuel received from a gas runner of the intake manifold, and one or more openings to fluidically couple the second groove to an interior of the intake air port. The insert is configured to mix gaseous fuel and intake air at a coupling location between the intake manifold and the cylinder head.
