摘要:
An oil control valve (60) that controls a variable valve timing gear for adjusting operation timing of at least one of exhaust and intake camshafts mounted on a cylinder head (1) of an internal combustion engine. The oil control valve comprises a housing (3) provided with plural oil lines; a spool type valve (5) that moves in the housing to open and close said oil lines; and a solenoid (31) having a metal case (33) that forms a part of a magnetic circuit and driving the spool type valve; and this housing (3) is mounted on the cylinder head (1) of said internal combustion engine. At least a part of the metal case (33) passes through a through hole (183) provided through a cylinder head cover (18) covering the cylinder head (1) and is disposed outside the cylinder head cover (18). As a result, all the essential part of the oil control valve (60) is disposed inside the head cover (18), and therefore space factor is improved. Even in case of oil leakage out of the solenoid (31), the oil flows in the head cover, and the oil does not leak out of the engine.
摘要:
Bei einem Verfahren zur Bestimmung der Lagerkräfte einer Welle, insbesondere für Einspritzpumpen von Brennkraftmaschinen, die durch ein antriebsnahes erstes Lager und ein davon beabstandetes antriebsferneres zweites Lager gelagert ist und an der außerhalb des Lagerbereichs - nach Art eines Kragträgers - Antriebskräfte angreifen, wird das durch die Antriebskräfte auf die Welle ausgeübte (Umlauf-) Biegemoment an einer antriebsseitig auf der Welle neben dem ersten Lager angeordneten Messstelle ermittelt. Daraus werden nach den Gesetzen der Mechanik die Lagerkräfte errechnet. Eine wesentliche Besonderheit wird darin gesehen, dass der zur Ermittlung der auf das erste Lager (Lager A) wirkenden Lagerkraft (F LA ) erforderliche Biegemomentenverlauf und daraus die Biegebelastung (F Z und F kt ) der Welle (10) durch eine erste Messstelle (Messstelle 1) und eine mit dieser zusammenwirkende zweite Messstelle (Messstelle 2) bestimmt wird und dass die zweite Messstelle auf der Welle (10) im Bereich des ersten Lagers (Lager A) vorgesehen wird.
摘要:
A fuel injection device for diesel engines which dispenses with brackets for a common rail and for a fuel supply pump, enables shortening of a fuel pipe, is space-saving with fewer parts, is lightweight and has a good maintainability. A common rail is mounted to a cylinder body, and a fuel supply pump is mounted to overlap the common rail, so that a fuel pressure-fed by the fuel supply pump is accumulated by the common rail to be injected into a fuel chamber of a cylinder.

A control system for a vehicle having an internal combustion engine with a turbocharger, and a transmission, in which the transmission, which can change a speed of the engine in accordance with a gear ratio, is coupled to the internal combustion engine, in which an output torque is increased in accordance with an increase in a boost pressure, for controlling a torque to be input to the transmission from the internal combustion engine to be equal to, or less than, a preset allowed torque, is characterized by having torque control means for setting, in accordance with the boost pressure of the turbocharger, a torque reduction amount from a torque reducing factor which reduces the input torque to the transmission by absorbing a portion of the torque to be output from the internal combustion engine (Steps S8 and S9).
摘要:
Die Betriebseinrichtung weist einen Starter (12) mit einem Elektromotor (14) zum Starten der Brennkraftmaschine (10) auf. Durch den Elektromotor (14) wird zum Starten der Brennkraftmaschine (10) über ein Getriebe die Kurbelwelle der Brennkraftmaschine (10) angetrieben. Die Brennkraftmaschine (10) weist eine Kraftstoffeinspritzeinrichtung auf, durch die Kraftstoff in die Ansauganlage oder direkt in die Brennräume der Zylinder der Brennkraftmaschine (10) eingespritzt wird. Die Kraftstoffeinspritzeinrichtung weist eine Kraftstoffpumpe (40) auf, um Kraftstoff in der erforderlichen Menge zu fördern und auf den erforderlichen Einspritzdruck zu verdichten. Für den Antrieb der Kraftstoffpumpe (40) wird der Elektromotor (14) genutzt, wobei die Kraftstoffpumpe (40) permanent oder nach dem Starten der Brennkraftmaschine (10) durch den Elektromotor (14) angetrieben werden kann. Für die Kraftstoffpumpe (40) ist somit kein eigener Antriebsmotor erforderlich.
摘要:
A controller is provided with an AC generator (1) the output voltage of which is adjusted by the manipulated variable of a field current which is made to flow through a field coil (102), a switching element (308) which intermittently controls the field current at a prescribed duty ratio, a voltage sensing means (305) which measures the output voltage of the generator (1), a gradual increase control means (4A) which gradually increases the conduction rate by gradually increasing the duty ratio in accordance with the measured output voltage, and a rotational speed sensing means (13) which measures the rotational speed of the generator (1). The control means (4A) increases the rate gradual increase of the duty ratio as the rotational speed measured by means of the sensing means (13) increases.
摘要:
A subtank (89) provided on a side wall of an engine block on an outboard motor temporarily stores a fuel supplied from a fuel tank not shown and provided on a hull, and pressurizes the fuel to a high pressure to deliver it to a fuel injection valve (94). An upper space in the subtank (89) is connected to an inner space of an intake silencer (76) through two air vent pipes (L7, L8). Even when a fuel vapor liquefies in the intake silencer (76) at the time of engine suspension, the liquefied fuel is caught at a bottom of the intake silencer (76) having a large volume with no possibility of flowing out.
摘要:
In an economy running mode, auxiliary machines (11, 16) are operated by a motor generator (3) in a state where the engine (1) is stopped so as to reduce electric power consumption. The motor generator (3), the engine (1) and the auxiliary machines (11, 16) are connected through pulleys and belts. Moreover, a clutch (26) is provided for switching enabling/disabling of power transmission between the motor generator (3) and the engine (1). A battery is connected to the motor generator (3) through an inverter. When the engine (1) is stopped, the clutch (26) is disengaged and the auxiliary machines (11, 16) are operated by the motor generator (3).
