In a multiple cylinder supercharged engine, a throttle, which is located downstream of a compressor driven by a turbine provided in an exhaust passage, through which exhaust gas of a cylinder group flows, is operated to a fully closed state, when all the c...

System for exhaust gas recirculation in a supercharged engine equipped with an ATS device, the engine (E) comprising an intake manifold (4), exhaust manifolds (5, 5'); wherein at least one of the exhaust manifolds is connected to the intake manifold (4) to...

The space for mounting an exhaust gas line to a V-type internal combustion engine comprising a first cylinder bank associated with a first exhaust manifold and a second cylinder bank associated with a second exhaust manifold may be limited. The disclosed e...

The unit (1) has an internal combustion engine (2) e.g. petrol engine, from which a high pressure exhaust manifold (9) emerges out for supplying fuel to an exhaust line (11). The line includes a turbine (12) for a turbo compressor. A low pressure exhaust m...

The method involves adjusting a first air/fuel mass ratio for differentiating fuel injection to each purge while a second air/fuel mass ratio is constant such that purging of nitrogen oxide traps (38, 40) converges in few iterations to obtain a complete an...

The present invention intends to perform control for detecting a change in air-fuel ratio with high accuracy by an exhaust gas sensor in an internal combustion engine having a turbocharger with a wastegate valve. A control apparatus for an internal combust...

The method involves determining a supercharged pressure set point (Cp), and a difference of air flow traversing two turbochargers. An actuating signal (At) of the turbochargers is determined to obtain the set point in a manifold. The turbochargers are cont...

The engine (1) has a two-stage turbocharger system. The inlet air (23) passes through a low-pressure compressor (17) driven directly (12) by a low-pressure turbine (16), and through a high-pressure compressor (14) driven (15) by two separate high-pressure ...
