[0002] An off-road power generation gas engine is usually a gas engine with a fixed speed and fixed location for power generation. The engine is connected to a generator, which drives the generator rotor to rotate and cut magnetic lines of force to generate electric energy.

[0003] An off-road power generation gas engine is different from a vehicle engine. The environmental pressure of a vehicle engine is constantly changing as the vehicle moves and may frequently switch between high-altitude and plain environments. Therefore, it is necessary to install an environmental pressure sensor to monitor the environmental pressure changes in real time and correct relevant performance parameters. However, an off-road power generation gas engine is fixed in one place, and the environmental pressure is almost constant. Here, the environmental pressure can be the environmental pressure at a fixed location because in the engine room, during the operation of the engine, the environmental pressure in the engine room is constant.

[0019] In order to enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] It should be noted that in the description, claims and the above drawings of the present application, terms such as "first" and "second" are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0021] As Figure 1 shown, according to one aspect of the embodiments of the present application, a method for detecting the ambient pressure of a non-road gas engine is provided. An upstream pressure sensor and a downstream pressure sensor are respectively arranged upstream and downstream of the throttle of the gas engine; the ambient pressure detection method includes:

[0022] S1 Determine whether the gas engine is in a preset working condition, and the preset working condition includes: the gas engine is in a shutdown working condition and the state of being powered on at T15 reaches a preset duration;

[0023] S2 If the gas engine is in the preset working condition, determine whether the gas valve is closed;

[0024] S3 Obtain the upstream pressure value of the throttle and the downstream pressure value of the throttle;

[0025] S4 Determine whether the upstream pressure value of the throttle and the downstream pressure value of the throttle meet the preset conditions;

[0026] S5 If the gas valve is closed and at least one of the upstream pressure value of the throttle and the downstream pressure value of the throttle meets the preset conditions, determine the current ambient pressure of the gas engine according to the pressure value that meets the preset conditions among the upstream pressure value of the throttle and the downstream pressure value of the throttle.

[0027] Perform subsequent steps when the gas engine is in the preset working condition. At this time, the engine state is stable, and the obtained pressure value is more accurate and stable; when the gas valve is closed and at least one of the upstream pressure value of the throttle and the downstream pressure value of the throttle meets the preset conditions, determine the ambient pressure, and no longer use the ambient pressure sensor, reducing costs; directly determine the engine ambient pressure according to the pressure values upstream and downstream of the throttle, which is simple and convenient to operate.

[0028] It should be noted that the preset condition may be a condition capable of characterizing the normal pressure values upstream and downstream of the throttle valve. That is, if the gas valve is closed and at least one of the upstream pressure value of the throttle valve and the downstream pressure value of the throttle valve is normal and there is no fault, the current ambient pressure of the gas engine is determined according to the normal pressure value among the upstream pressure value and the downstream pressure value of the throttle valve. The present application does not make further limitations on this.

[0029] It should also be emphasized that the power-on of T15 in the present application refers to the power-on state of the engine electronic control unit, and at this time the engine speed is 0.

[0030] As an optional implementation manner, the ambient pressure detection method further includes: if the gas engine is in the shutdown condition and the power-on state of T15 has not reached the preset duration, setting the current ambient pressure of the gas engine as the calibrated pressure value.

[0031] Since the gas engine is in the shutdown condition and the power-on state of T15 has not reached the preset duration, it can be considered that the engine is in an unstable state. At this time, the current ambient pressure value can be determined according to experience and the ambient pressure at the location of the engine. The calibrated pressure value can be a fixed value determined by technicians according to the actual situation.

[0032] As an optional implementation manner, the ambient pressure detection method further includes: when the gas engine is in the idle condition, determining whether the upstream pressure value and the downstream pressure value of the throttle valve meet the preset conditions; if the gas valve is closed and at least one of the upstream pressure value and the downstream pressure value of the throttle valve meets the preset conditions, determining the current ambient pressure of the gas engine according to the pressure value that meets the preset conditions among the upstream pressure value and the downstream pressure value of the throttle valve.

[0033] When the gas engine is not in the preset condition but in the idle condition, the engine can still update the ambient pressure in real time, further improving the accuracy of ambient pressure determination.

[0034] As an optional implementation manner, determining the current ambient pressure of the gas engine according to the pressure value that meets the preset conditions among the upstream pressure value and the downstream pressure value of the throttle valve includes: if the upstream pressure value of the throttle valve meets the preset conditions and the downstream pressure value of the throttle valve does not meet the preset conditions, determining the current ambient pressure of the gas engine according to the upstream pressure value of the throttle valve.

[0035] As an alternative implementation, determining the current ambient pressure of the gas engine based on the pressure value that meets the preset condition among the upstream pressure value of the throttle valve and the downstream pressure value of the throttle valve includes: if the upstream pressure value of the throttle valve does not meet the preset condition and the downstream pressure value of the throttle valve meets the preset condition, determining the current ambient pressure of the gas engine according to the downstream pressure value of the throttle valve.

[0036] As an alternative implementation, determining the current ambient pressure of the gas engine based on the pressure value that meets the preset condition among the upstream pressure value of the throttle valve and the downstream pressure value of the throttle valve includes: if both the upstream pressure value of the throttle valve and the downstream pressure value of the throttle valve meet the preset condition, determining the current ambient pressure of the gas engine according to the upstream pressure value of the throttle valve and / or the downstream pressure value of the throttle valve.

[0037] Specifically, when both the upstream pressure value of the throttle valve and the downstream pressure value of the throttle valve meet the preset condition, that is, the pressures upstream and downstream of the throttle valve are both normal, the pressure upstream or downstream of the throttle valve can be selected respectively to determine the ambient pressure. At the same time, the pressure values upstream and downstream of the throttle valve can also be combined to determine the ambient pressure. For example, calculate the average value of the upstream and downstream pressure values or determine that the more accurate pressure among the upstream and downstream has a higher weight according to experiments to determine the ambient pressure.

[0038] As an alternative implementation, determining the current ambient pressure of the gas engine based on the pressure value that meets the preset condition among the upstream pressure value of the throttle valve and the downstream pressure value of the throttle valve includes: within one sampling period, continuously obtaining multiple pressure values that meet the preset condition among the upstream pressure value of the throttle valve and the downstream pressure value of the throttle valve; calculating the average value of the pressure values obtained within one sampling period; continuously obtaining the average values of the pressure values within multiple sampling periods until the gas engine is no longer in the preset working condition; setting the average value of the pressure values within the last sampling period as the current ambient pressure of the gas engine.

[0039] For example, set to uniformly and continuously sample 20 pressure values within one sampling period, calculate the average value of the 20 pressure values as the pressure value of the current sampling period. If the gas engine is still in the preset working condition after one sampling period, the average pressure values of consecutive multiple sampling periods can continue to be determined until the gas engine is no longer in the preset working condition, and then the average pressure value of the last sampling period is used as the ambient pressure value of the gas engine.

[0040] According to another aspect of the present application, an environmental pressure detection system for a non-road gas engine includes: a working condition judgment module for judging whether the gas engine is in a preset working condition, where the preset working condition includes: the gas engine is in a shutdown working condition and the state of being powered on at T15 reaches a preset duration; a gas valve state judgment module for judging whether the gas valve is closed when the gas engine is in the preset working condition; a pressure value acquisition module for acquiring the upstream pressure value of the throttle valve and the downstream pressure value of the throttle valve; a condition judgment module for judging whether the upstream pressure value and the downstream pressure value of the throttle valve meet preset conditions; and an environmental pressure determination module for determining the current environmental pressure of the gas engine according to the pressure value that meets the preset conditions among the upstream pressure value and the downstream pressure value of the throttle valve when the gas valve is closed and at least one of the upstream pressure value and the downstream pressure value of the throttle valve meets the preset conditions.
