Abstract: A method for controlling an engine includes the steps of, in response to a transient operating event, determining a first amount of exhaust gas recirculation (EGR) that if provided to an intake of the engine would avoid turbocharger compressor surge in a turbocharger, determining a second amount of EGR that if provided to the intake would avoid turbocharger compressor choke in the turbocharger, and determining a third amount of EGR that if provided to the intake would avoid engine smoking, and adjusting EGR provided to the intake of the engine in accordance with the determined first, second, and third amounts.

Abstract: A method for operating an internal combustion engine (10) that has at least one cylinder row (11a, 11b) with first and second exhaust-gas turbochargers (13a, 13b; 14a, 14b). Charge air is provided by the first exhaust-gas turbocharger (13a, 13b) in single-charger operation, but is provided by the first and second exhaust-gas turbocharger (13a, 13b; 14a, 14b) in two-charger operation. To switch from single-charger to two-charger operation above a load threshold value of the internal combustion engine (10), when a speed of the internal combustion engine (10) reaches or overshoots a threshold value, a charge pressure is increased to build up a torque reserve and a charge pressure reserve and to maintain a driver demand torque. When the charge pressure reaches or overshoots a threshold value, a switch is made from single-charger operation to two-charger operation, and subsequently, the torque reserve and the charge pressure reserve are eliminated.

Abstract: A multi-stage exhaust turbocharger has parallel high pressure stages (30, 40), and a single low pressure stage (60) in series. The low pressure stage (60) has a divided scroll turbine wheel 62 with each scroll fed independently from the respective turbines of the high pressure stage. Valves V1, V2, V3 determine flow paths to the respective turbines to ensure series sequential operation.

Abstract: The invention relates to a method for determining the pressure Pavcm upstream of a mechanical compressor (3) equipped with a double supercharging circuit of a combustion engine. The pressure Pavcm is determined by a dynamic model based on a law of conservation of flow rate in the volume upstream of the mechanical compressor. The model links the pressure Pavcm upstream of the mechanical compressor (3) to a temperature Tavcm upstream of the mechanical compressor (3), to a boost pressure Psural and boost temperature Tsural on the intake side of the engine, and to an openness Bypass of the bypass valve (4).

Abstract: An induction system for a supercharged internal V-type combustion engine includes a monolithic continuous unitary casting housing a supercharger with a rotor and gear assembly operative to discharge pressurized air to a common bounding receiving plenum, through a first slidably-removable intercooler providing a first cooling, and then to a pair of second side intercoolers providing a second cooling within the bounded plenum and in fluid communication therewith. First and second intercoolers are secured within the monolithic housing. The monolithic housing provides a robust and stable housing of light weight and allows an exterior air cooling as well. Side walls of the supercharger are separate from and are spaced from air intake runners of a cylinder block. Air in the plenum is additionally cooled by convective surface cooling while being guided in an appropriate direction. The intercoolers are plumbed in parallel allowing for enhanced temperature management of the air flow in combination with the convective cooling. The monolithic housing includes rib elements for sound attenuation and strength while minimizing weight. This arrangement allows for enhanced cooling, and simplifies manufacture and service.
