摘要： A turbine housing for a turbocharger for use in a reciprocating internal combustion engine includes a housing having a housing axis and configured to house a rotatable shaft having a turbine wheel disposed thereon. The housing includes a volute having a volute chamber disposed around the housing axis for receiving the turbine wheel. The volute has a first volute inlet providing a first flow path in fluid communication with the volute chamber and second volute inlet providing a second flow path in fluid communication with the volute chamber. The first volute inlet is circumferentially spaced about the housing axis from the second volute inlet by a phase angle α. The first volute inlet is also radially spaced about the housing axis from the second volute inlet, and may also be axially spaced from the second volute inlet along the housing axis.

摘要： An exhaust gas recirculation system comprises an exhaust driven turbocharger to deliver a compressed intake charge through an intake charge conduit and to an engine. A compressed intake charge cooler receives, cools and transits the compressed intake charge. A cooling system, independent of the engine cooling system delivers coolant to the compressed intake charge cooler to transfer heat from the compressed intake charge thereto and to a cooler. Exhaust gas conduits extend between the exhaust system of the internal combustion engine, from locations upstream and downstream of the exhaust driven turbocharger, to the intake charge conduit. Exhaust gas coolers receive, cool and transit the exhaust gas.

摘要： A combustion chamber for a swirl flow two valve spark ignition direct injection engine includes a cylinder with a closed end having a wedge shaped combustion chamber recess. A fuel injector extends through the closed end near a shallow side of the wedge recess. A spark plug extends through the closed end at a deeper part of the wedge recess opposite from the injector. A single pair of laterally spaced intake and exhaust valves control intake and exhaust ports opening into the wedge recess. A piston in the cylinder has an outer diameter and includes a head end having a raised pedestal with a shallow upwardly angled face ending at a raised ridge and enclosing a shallow bowl in the head end. The bowl is generally oval with a major dimension generally aligned with a cylinder centerline through the valves.

摘要： An intake reservoir system is for an engine having an intake passage leading to a cylinder, and a check valve in the intake passage to allow fluid flow toward the cylinder and obstruct fluid back-flow in the reverse direction. A bypass port is located on the intake passage so that the bypass port communicates with a trapped volume defined by the portion of the intake passage between the check valve and cylinder. The intake reservoir system comprises an inflower for enabling fluid to flow into the trapped volume when the pressure therein is at least equal to the pressure upstream of the check valve. The intake reservoir system further comprises a reservoir cavity, a port passage connected between the reservoir cavity and bypass port enabling communication between the reservoir cavity and trapped volume, and a volume controller enabling adjustment of the volume of the reservoir cavity.

摘要： An intake system for an internal combustion engine comprises an exhaust driven turbocharger configured to deliver compressed intake charge, comprising exhaust gas from the exhaust system and ambient air, through an intake charge conduit and to cylinders of the internal combustion engine. An intake charge cooler is in fluid communication with the intake charge conduit. A cooling system, independent of the cooling system for the internal combustion engine, is in fluid communication with the intake charge cooler through a cooling system conduit. A coolant pump delivers a low temperature cooling medium from the cooling system to and through the intake charge cooler for the transfer of heat from the compressed intake charge thereto. A low temperature cooler receives the heated cooling medium through the cooling system conduit for the transfer of heat therefrom.
