TLDR
In this article, a split exhaust flow system for a multi-cylinder internal combustion engine with an exhaust-driven supercharger of the turbocompressor type is presented, where each cylinder of the engine has both a first exhaust valve and a second exhaust collector common to the cylinders.Abstract:
Exhaust flow system for a split exhaust flow in a multi-cylinder internal combustion engine (3) fitted with an exhaust-driven supercharger (2) of the turbocompressor type, whose exhaust system incorporates a catalytic exhaust cleaner (58; 58'), where each cylinder of the engine has both a first exhaust valve (51), from which released exhaust gas is fed to a first exhaust collector (53) common to the cylinders, which collector is connected directly to the exhaust turbine inlet by a first exhaust branch pipe (54), and a second exhaust valve (52), from which released exhaust gas is fed to an exhaust pipe (56), which incorporates a silencer (61). At least one valve (50) adjustable according to the operating conditions of the engine (3), is arranged downstream from the second exhaust valves (52) of the cylinders, in their connection (59, 55, 57) to the exhaust pipe (56) between the exhaust turbine outlet (20) and the silencer (61).read more

Arrangement for turbo regulation in an internal combustion engine
S Jiewertz Jaerna,Mats Eriksson +1 more
TL;DR: In this article, an arrangement for obtaining increased possibilities of regulating a supercharged internal combustion engine is presented. But the main purpose of this arrangement is to provide the driver with the possibility of adapting the supercharging level for a number of partial speed ranges in the speed range of the engine.
