摘要:
A turbocharging system for use with an internal combustion engine (1), which includes an exhaust gas feeding passage (5) configured to feed exhaust gas of an internal combustion engine (100) toaturbineunit (20); anexhaustgaspassage (6) configured to release the exhaust gas discharged from the turbine unit (20) outside of the turbocharging system; an intake air passage (7) configured to feed intake air into the compressor unit (30); a compressed air passage (33) configured to feed compressed air discharged from the compressor unit (30) to the internal combustion engine (100) ; an intercooler (108) configured to cool the compressed air flowing through the compressed air passage (33); and an LPL-EGR passage (8) configured to recirculate at least a part of the exhaust gas flowing through the exhaust gas passage (6), into the intake air passage (7), wherein the compressed air passage (33) is provided with a cyclone-type collecting device (9) arranged upstream of the intercooler (108) to collect foreign substances contained in the compressed air.
摘要:
The present invention provides a variable valve mechanism, which includes a rocker arm including an input member and an output member; a switching device that switches a drive state of the valve by displacing the switching pin between a coupling position at which the switching pin extends between the first pin hole in the input member and the second pin hole in the output member and a non-coupling position at which the switching pin does not extend; and a lost motion spring. A displacement clearance is formed between an inner peripheral surface of the first or second pin hole and an outer peripheral surface of the switching pin to permit the relative displacement in a range of the displacement clearance at a coupled time so that a tappet clearance is not formed with the input member urged toward the cam by the lost motion spring.

A lash adjuster includes a body (11), a plunger (12) inserted into the body (11) and a partitioning member (13, 13A) inserted into the plunger (12). The plunger (12) has a bottom wall (18) with a valve hole (20) and a peripheral wall (19) having an oil passage hole (26). The plunger (12) defines a high-pressure chamber (22) between the bottom wall (18) and the body (11). The partitioning member (13, 13A) has a plate-like baffle (39) located opposite the passage hole (26). The baffle (39) has an upper end serving as an oil passage end (33) located above the passage hole (26). The plunger (12) has interior divided into two spaces by the baffle (39). The passage hole (26) is located at one space side. An oil passage (40) is defined at one space side. A low-pressure chamber (23) is defined at the other space side to store hydraulic fluid flowing through the passage hole (26), the oil passage (40) and the passage end (33). The low-pressure chamber (23) supplies the fluid through the valve hole (20) into the high-pressure chamber (22).

A compressor housing (1) includes a scroll member (2), a shroud member (4), and an annular member (6). The scroll member (2) has a first positioning portion (31), which contacts the shroud member (4) to determine the position of the shroud member (4) in relation to the scroll member (2) in the circumferential direction of the impeller (8), and a second positioning portion (32), which contacts the annular member (6) to determine the position of the annular member (6) in relation to the scroll member (2) in the circumferential direction of the impeller (8). The first positioning portion (31) and the second positioning portion (32) are formed at the same position in the circumferential direction of the impeller (8).
