Circuit arrangement of suction, exhaust and fuel system of supercharged internal combustion engines with a requirement for higher operating pressure of gaseous fuel

摘要

An engine (1) exhaust manifold (3) is divided into two mutually separated branches such that exhaust gas mass flow ratio in the branch for the turbine / turbocharger turbine / turbochargers (5) of a gaseous fuel compression system to the exhaust gas mass flow in the branch for the turbine / / turbocharger turbine / turbochargers (4) of the combustion air /combustion mixture compression system corresponds to the ratio of the compressed gaseous fuel mass flow to the compressed combustion air / mixture mass flow.
