摘要:
The dual pass intercooled supercharger includes a supercharger and intercooler. The system is configured such that air leaving the supercharger traverses the intercooler from one side to an opposing side two or more times.
摘要:
A dual-injector fuel injection engine has intake ports (11) each extending at cylinder head (6) obliquely upward from a combustion chamber (16); an intake manifold (21) connected at its downstream side end section to the intake ports (11); an in-cylinder injector (15) for each of the cylinders, injecting fuel directly into the combustion chamber (16); and an intake pipe injector (56) for each cylinder, injecting fuel into the intake port (11). The in-cylinder injector (15) is attached to the cylinder head (6) and is positioned on the lower side of the intake port (11) when viewed from the direction of the axis of a crankshaft (27). The intake pipe injector (56) and a low-pressure delivery pipe (57) for supplying fuel to all the intake pipe injectors (56) are supported at the intake manifold (21), and are positioned, when viewed from the direction of the axis of the crankshaft (27), on the upper side of the intake port (11) so as to be close to the intake port (11).
摘要:
In a variable intake apparatus for a V-type internal combustion engine, each of plural intake pipes (1) is separated from a surge tank (2) by a partition wall (3), and communication ports (31), provided in the partition wall (3) for the respective intake pipes (1), are opened and closed by respective variable intake valves (4) to adjust length of intake passages. The variable intake valves (4) in one of two parallel rows are offset from the variable intake valves (4) in the other row. The variable intake valves are opened and closed by turning the turning shafts (5a; 5b) to which the variable intake valves (4) are connected. Further, a synchronization mechanism (6) synchronously turns the turning shafts (5a; 5b), and is connected between the paired turning shafts (5a; 5b). The turning motion of one turning shaft (5a) is transmitted to the other turning shaft (5b) via the synchronization mechanism (6), and the variable intake valves (4) are synchronously opened and closed.
摘要:
The invention relates to a valve unit (1) for influencing and/or controlling a gas flow in an internal combustion engine (2), especially of a motor vehicle, comprising at least one valve member (3) for modifying a cross-section of a gas flow-carrying channel (4) through which a fluid can flow and a drive train (5) for rotatingly driving the at least one valve member (3). The drive train (5) comprises an input shaft (8) which is drivingly coupled to a drive device (31) in the mounted state, and at least one valve member shaft (10) which is non-rotationally connected to the valve member (3). It is especially advantageous if the drive train (5) comprises at least one phase adjuster (11) for drivingly coupling the input shaft (8) and the valve member shaft (10), a rotational position of the shafts (8, 10) in relation to each other being adjustable by the phase adjuster.
摘要:
Die Erfindung betrifft einen Ladeluftkühler für Verbrennungsmotoren, insbesondere für Großmotoren, umfassend ein Luftführungsgehäuse (2), in welchem ein Kühlblock aufgenommen ist, mindestens ein Luftanschlussgehäuse (3, 4), wobei das Luftführungsgehäuse (2) und der Kühlblock eine dreidimensionale Erstreckung in den Koordinatenrichtungen x, y, z aufweisen, wobei die x-Richtung etwa horizontal und parallel zur Richtung der Kurbelwelle des Motors verläuft, die y-Richtung ebenfalls etwa horizontal und senkrecht zur x-Richtung und die z-Richtung etwa vertikal verläuft. Es wird vorgeschlagen, dass das Luftführungsgehäuse in einer vertikalen Ebene (E1, E2) in zwei äußere Gehäuseteile (2a, 2b) geteilt und dass zwischen die beiden äußeren Gehäuseteile ein mittleres Gehäuseteil (2c) unterschiedlicher Abmessung (b) einsetzbar ist.
