Title:
内燃機関を駆動する方法及び内燃機関
Document Type and Number:
Japanese Patent JP4073719
Kind Code:
B2
Abstract:
In an internal-combustion engine having an exhaust-gas driven supercharger (8) and having at least two exhaust-gas valves (2, 3) per cylinder, a first exhaust-gas valve (2) in each cylinder is connected to a first exhaust manifold (4), whilst a second exhaust-gas valve (3) in each cylinder is connected to a second exhaust manifold (5). The two exhaust manifolds (4, 5) lead to at least one exhaust-gas turbine in at least one turbo compressor and the first exhaust-gas valves (2) are arranged to be opened at all engine speeds, whilst the second exhaust-gas valves (3) are arranged to be opened only at higher engine speeds. The first exhaust manifold (4) has a smaller flow area than the second exhaust manifold (5). By choosing which exhaust-gas valves are to be used, the size of the flow ducts between engine and exhaust-gas turbine can easily be suited to the size of the exhaust-gas flow which is available at the time.
