Problems solved by technology

When the ship is reversing, the propeller will suddenly apply a large torque to the engine from forward to reverse. At this time, if the engine is not refueled in time, it will cause the flameout

Embodiment Construction

[0013] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0014] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0015] Such as figure 1 As shown, according to the preferred embodiment of the present invention, the anti-turning ship flameout method does not require rewiring, no corresponding switch, and only basic data preparation. When the function enabling calibration word (FDM_ShipForRFuelEn_Vac) is 1, it means that the anti-turning ship flameout function is available.

[0016] In the engine idle state, when the transient speed dr...

Abstract

The invention discloses a flame-out method for an anti-overturning ship. In the engine idling state, when the transient speed change rate of the engine reaches a set value, the engine is compensated for the amount of fuel to avoid engine flameout caused by untimely refueling when the ship is in reverse. The anti-overturning ship flameout method performs oil quantity compensation according to the rate of change of the rotational speed, and avoids flameout caused by untimely refueling of the engine when the ship is reversed.

Description

technical field [0001] The invention relates to the field of engines, in particular to an anti-overturning ship flameout method. Background technique [0002] Ships need a propulsion device during navigation, which converts the power generated by the engine into the thrust of the ship, so as to overcome the resistance of the ship navigating in the water and improve the performance of the ship. The most commonly used is the propeller. When the ship is reversing, the propeller will suddenly apply a large torque to the engine from forward to reverse. At this time, if the engine is not refueled in time, it will cause the engine to stall. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art.
