摘要： PROBLEM TO BE SOLVED: To provide a cyclone type oil separator suppressing the re-splashing of oil separated in a body than ever.
SOLUTION: Since a recessed groove 60 extending in the orthogonal or approximately orthogonal direction to the inflow direction to the body part 20 of oil-mixed gas is disposed to a sidewall inner surface 22c of the body 20, the centrifuged oil entering into the groove 60 can be flowed to an oil discharge part 50 through the most direct way or through approximately the most direct way. Compared with such a case that the centrifuged oil flows down the inside of a spiral groove, the travel of the oil to the oil discharge part 50 can be shortened to suppress the re-splashing of the oil.

摘要： PROBLEM TO BE SOLVED: To provide an oil particle collecting device capable of suppressing increase of pressure loss and efficiently collecting oil particles.
SOLUTION: The oil particle collecting device 1 has a space forming body 3 for forming a space through which gas can circulate, and is equipped with a plurality of partitioning parts 20-29 between gas inflow ports 6, 7 of the space forming body 3 and a gas discharge port 9. Collecting parts 40-45 comprising a plurality of protruding parts 47 are formed protruding from an inner wall of the space forming body 3 arranged in the advancing direction of gas flow. The gas contacting area, especially the area where gas flow is apt to collide into, is increased by the collecting parts 40-45. Oil particles in the gas which have collided into the collecting parts 40-45 adhere to the collecting parts 40-45 or drop out from the gas flow due to decrease in propulsive force. Adhesion rate and dropping out rate of the oil particles are improved because gas which goes in between the protruding parts 47 arranged in the advancing direction of the gas flow collides into the protruding parts 47 on both sides.

摘要： PROBLEM TO BE SOLVED: To provide an acoustic shield for an injector which reliably intercepts noise of injector to be installed to the exterior of the engine body by providing portions in the shield where members can come out of the inside to the outside thereof. SOLUTION: An acoustic shield 17 is composed of a support plate 18 and a shield material 19 which is provided so as to cover the entire inner surface of the support plate 18. A delivery pipe 16 and a fastener 22 are inserted from the inside to the outside of the support plate 18 through an insertion groove 21a and an insertion hole 21b, respectively. A fold portion 23 presses and abuts against the delivery pipe 16 due to elasticity of the shield material 19, thereby closing the abutting portion. When installed to an installation seat 28, the fastener 22 presses and abuts against the installation seat 28 due to elasticity of the shield material 19, thereby closing the abutting portion. Fold portions 30 are formed on the entire perimeters of abutting portions 20 to abut along the shape of an engine body 11 and close the abutting portions.

摘要： PROBLEM TO BE SOLVED: To provide an oil separation device of an engine even in the case of enhancing oil separation performance capable of effectively preventing a blow-by gas from being sucked from an opening at a lower end of an oil drain passage into a gas-liquid separation chamber, and capable of effectively preventing sludge from being generated.
SOLUTION: The oil separation device of an engine is disposed in a flow path for circulating a blow-by gas generated in the engine, into an intake passage. The oil separation device makes the blow-by gas pass through a gas-liquid separation chamber 51 at which oil components are separated in a recoverable manner. The oil separation device includes: a bottom wall member 61 that constitutes an inner bottom wall surface 51a of a gas-liquid separation chamber 51 so as to recover oil separated at the gas-liquid separation chamber 51; and a cylindrical drain passage constituting member 62 that protrudes from the bottom wall member 61 downward in the vertical direction and constitutes a drain passage 65 communicating with the gas-liquid separation chamber 51. The drain passage constituting member 62 has a narrowed part 63 that narrows a part 65a of the drain passage 65 compared to a remaining part 65b so that oil in the drain passage 65 blocks the part 65a of the drain passage 65.
