A turbo compound engine which comprises an engine having an intake air passage, an exhaust gas passage and a crankshaft, a power turbine disposed in the exhaust gas passage so as to be rotatable in normal and reverse senses, a reversing mechanism for connecting the power turbine with the crankshaft, an exhaust bypass line connected to the exhaust gas line so as to bypass the power turbine, first and second shut-off valves respectively disposed in the exhaust gas line upstream of the junctions of the exhaust bypass line and the exhaust gas passage, so that they may be closed upon reversed switching of the reversing mechanism an intake air bypass line connected to the intake air passage at one end thereof and to the exhaust gas passage downstream of the power turbine and upstream of one of the junctions with the exhaust bypass line at the other end, a third shut-off valve disposed in the intake air bypass line so as to be opened as the rotation of the power turbine is reversed and reaches a predetermined value.

A turbo compound engine comprising: an engine having an intake air passage, an exhaust gas passage and a crankshaft; a power turbine disposed in the exhaust gas passage so as to be rotatable in normal and reverse senses; a reversing mechanism for connecting the power turbine with the crankshaft in a manner such that the power turbine and the crankshaft may rotate in the same direction or the opposite direction in accordance with switching thereof; an exhaust bypass line connected to the exhaust gas line at two junctions so as to bypass the power turbine; first and second shut-off valves respectively disposed in the exhaust gas line upstream of said two junctions of the exhaust bypass line and the exhaust gas passage, so that they may be closed upon reversed switching of the reversing mechanism; an intake air bypass line connected to the intake air passage at one end thereof and to the exhaust gas passage downstream of the power turbine and upstream of one of the junctions with the exhaust bypass line at the other end; a third shut-off valve disposed in the intake air bypass line; and, control means for detecting the rotation of the power turbine, and for opening the third shut-off valve when the control means detects that the rotation of the power turbine is reversed and reaches a predetermined value.
