Abstract: Ein Abgasrohr 1 eines Motors umfasst ein kurbelförmiges Rohrteil 11, welches eine erste Biegung 11a und eine zweite Biegung 11b aufweist, die Abgas zu einem Mischelement 5 leiten, und ein gerades Rohrteil 12, in welches die zweite Biegung 11b übergeht. Das Mischelement 5 ist in dem geraden Rohrteil 12 angeordnet. Ein Injektor 4 ist in einem dem Mischelement 5 gegenüberliegenden Abschnitt der zweiten Biegung 11b angebracht. Die Injektionsachse des Injektors 4 erstreckt sich in Längsrichtung des geraden Rohrteils 12 und läuft auf das Mischelement 5 zu. Eine Führung 15, die einen Teil des Abgases von der ersten Biegung 11a zu dem Injektor 4 leitet, ist im Inneren des kurbelförmigen Rohrteils 11 angeordnet.

Abstract: PURPOSE: To form the part in the longitudinal direction of an engine and the lower part in the direction of width of the engine in a compact manner by a method wherein a fuel injection pump and a plurality of auxiliary machines are arranged concentratedly to one side of the engine as drive performance of a plurality of auxiliary machines driven by an auxiliary machine drive belt is maintained in an excellent state. CONSTITUTION: In an OHC diesel engine wherein a plurality of lock parts are arranged in a rotation direction, a fuel injection pump 41 and one cam shaft 6 are driven by an engine output shaft 19 through an endless running member 17 to prevent the occurrence of staggering of a timing, a fuel injection pump 41 is arranged in such a manner to be partially positioned to one side of a cylinder head 3 at least in the central line of a cylinder through a cylinder head 3 having a cam bearing part. A plurality of auxiliary machines 42 and 43 driven by an engine output shaft 19 through an auxiliary machine drive belt 18 are vertically juxtaposed below a fuel injection pump 41.

Abstract: PURPOSE:To improve the responsiveness of a fuel without increasing an air blow-out in a gaseous fuel engine. CONSTITUTION:An auxiliary passage 51 is provided so that a hydrogen storage part 16 and a working chamber 4 of the suction stroke may be communicated by bypassing a hydrogen control valve 19, and an auxiliary valve 52 is arranged in the auxiliary passage 51. The outlet side (A) of the auxiliary control valve 52 is connected to the upstream part of a fuel injection valve 18. The outlet side (A) of the auxiliary control valve 52 may be connected (B) to a downstream passage 35 of the fuel injection valve 18, or may be connected (C) to an auxiliary intake port 6A for the high intake amount zone. This constitution can improve the responsiveness of the fuel by making the auxiliary control valve 52 compact, and bringing it close to the engine body 1, and the increase of the air blow-out can be prevented by making use of the existing passages 17, 51 or the ports 6, 6A, 8 to supply the auxiliary fuel.

Abstract: PROBLEM TO BE SOLVED: To accomplish mounting of a weight to an exhaust system by a simple and inexpensive constitution in an exhaust system supporting device for a vehicle provided with a hanger for hanging/supporting the exhaust system relative to a vehicle body.
SOLUTION: The other end side of a rod-like member 46 having one end side engaged with the hanger 42 is fixed onto an outer peripheral surface of a pre-silencer 23 by a mounting bracket 48 of an approximately M shape cross section. Specifically, the other end side of the rod-like member 46 is welded/fixed into a central groove part 48c of the mounting bracket 48 in such a state that it is adjusted along a predetermined length. The groove part 48c has a depth not less than a diameter of the rod-like member 46. A square pole-like weight 50 is welded/fixed onto a ceiling part 48b of the mounting bracket 48.
