Übersetzung für "Vor ot" in Englisch

The basic value should ideally be indicated in degrees in front of the OT of the working cylinder.

Thus, the ignition may take place up to 25 mm before OT .

It's set at a few degrees before TDC

We installed it and set the timing to about 5 degrees after TDC.

The most honorable and brave officers and citizens now stand before me, our OT Project teams.

In response to activating the ignition output, the cylinder position is before OT by the angle of the basic value.

However, this occurs before TDC, the engine can strike back e.g. when actuating.

When the paint chamber 18 is completely filled with paint, whereby a corresponding pressure can build up, the membrane 15 performs its full stroke from the UT to a point shortly before the OT, i.e. the diaphragm movement is now more shifted towards the UT.

Even if the ignition in the main combustion chamber should begin shortly before the top dead center, the ignition will cause the pressure to rise to a peak initially in the ignition prechamber or chambers, so that the pressure in said chamber or chambers will rise.

For this purpose, as the intake valve E is opened, the exhaust valve A is either simultaneously closed or is closed with a certain overlap (in the graph, the exhaust valve A is opened approximately 30° prior to OT until 30° crank angle after OT).

Analytical tests have shown that a maximum braking effect occurs if in addition to a second opening phase of the exhaust valve during normal operation between the points 15 and 16, via the hydraulic pump unit 5 (FIG. 1) the first opening phase between the points 13 and 14 is initiated between the crank angles 180°.+-.40° prior to the ignition dead center point OT and 40°.+-.40° after the ignition dead center position OT.

A simple fixed-capacity fuel injection pump is desirably employed and in accordance with a preferred feature of the invention is arranged to inject fuel directly into the injection chamber shortly before the top dead center in a quantity which is sufficient for the ignition.

With increasing load, the instant of injection is shifted toward "early", so that at maximum load the injection is terminated at 70° to 90° prior to top dead center.

In a region of the rpm n lying above the idling speed nLL, the ignition timing is adjusted toward "early" so that ignition takes place by a specific larger ignition angle a before TDC.

As may be seen from FIG. 1, the course of the signal begins before the top dead center position OT of the cylinder, and as a rule it takes the approximate form of a bell-shaped curve.

For opening the outlet valve before the ignition top dead center position is reached, a hydraulically actuated valve push rod is arranged between the outlet cam and the outlet valve which is actuatable by an external pressure source.

When it is desired to lift the outlet valve before the ignition top dead center position, the hydraulic pump unit is actuated and the pressure chamber is filled with the pressure medium so that the inner portion will lift the outlet valve via the valve push rod against the force of the valve spring, whereby the outlet valve lifter in this phase rests at the base circle of the cam shaft.

Referring to the sixth exemplary embodiment shown in FIG. 7, it will be observed that the above-described apparatus for attaining quiet engine operation during idling and in the partial-load range can also be realized when the annular slide 24" controls not the end of pump piston supply at an earlier or later point prior to top dead center, but rather the onset of pump piston supply following an idle pump piston stroke of variable length.

The manner of function of this version differs from the one according to FIGS. 1 to 3 by virtue of the fact that this one permits a metering for the high pressure reservoir 2 and a diversion before the top dead center.

Another option when a dangerous situation is recognized involves controlled, very early fuel injection during the compression stroke long before TDC is reached, with the engine braking power being further increased as a result.

The intake valve 18 and the outlet valve 24 are controlled such that, for example, the inlet valve opens 27.5° before OT and closes 38.5° after UT and such that the outlet valve opens 57° before UT and closes 25° after OT.

Once the piston has reached the position of 27.5° before OT, the intake valve 18 opens and the outlet valve 24 closes upon reaching the position 25° after OT; whereby the operational condition shown in FIG.

With the indexing apparatus connected for evaluation and consisting of 4 quartz sensors and a commercial indexing apparatus (AVL-Indiskop), the pressure variations in the range of interest for each combustion, extending from a crank angle of 30° before the upper dead center to a crank angle of 30° after the upper dead center, can be monitored.

In a region of the rpm n lying above the idling speed nLL, the ignition timing is adjusted toward "early" so that ignition takes place by a specific larger ignition angle a before TDC.

The pulse from second sensor (sensor A and magnet A on the left drawing) is early 12 ° before the TDC.

As a proof the argument has no force, for the same word zera 'occurs in the sing, form in every passage in the OT where it expresses the idea of offspring.

During the upward movement of the valve bridge 7, the piston 16 of KZE 2 abuts against the counter bracket 14 shortly before TDC, whereby the outflow bore 16 b is closed.
