The pressure value and the temperature value are collected at the same time, and the fuel supply amount is adjusted according to the pressure difference value and the temperature difference value, so that the air-fuel ratio of the engine is better, the engine runs stably, and the noise is lower.
The control system is described in detail below.
Fig. 1 shows a schematic diagram of a vaporizer, an engine, and a control system, and referring to fig. 1, the first fuel state detection mechanism includes a first temperature detection device 41 and a first pressure detection device 42 provided at an outlet of the vaporizer 20.
The gasifier 20 is connected with the engine through a connecting pipeline. That is, the first temperature detecting device 41 and the first pressure detecting device 42 are provided on the connection line near the gasifier 20.
The first temperature detection device 41 is a temperature sensor. The first pressure detecting device 42 is a pressure sensor.
The second fuel condition detection mechanism includes a second temperature detection device 51 and a second pressure detection device 52 provided on the gas injection valve 30 of the engine.
The second temperature detection device 51 is a temperature sensor. The second pressure detecting device 52 is a pressure sensor.
The control mechanism simultaneously receives the first temperature, the first pressure, the second temperature and the second pressure, analyzes according to the difference value between the first temperature and the second temperature and the difference value between the first pressure and the second pressure, and outputs a control signal to control the fuel supply amount delivered to the cylinder of the engine.
Specifically, the control mechanism is electrically connected to the fuel injection valve 30 of the engine, thereby controlling the amount of fuel injected into the cylinder by the fuel injection valve 30.
Further, the control mechanism adjusts the operating parameter of the vaporizer 20 to adjust the first temperature based on the second temperature, the second pressure, and the condition of the engine.
For example, in the actual situation of the second temperature, the kinetic energy of the engine is not enough, and in the situation that the second temperature needs to be increased, the control mechanism controls the gasification temperature of the gasifier 20 to be increased so as to increase the first temperature, thereby achieving the situation that the second temperature is increased.
For example, when the vaporizer 20 is a water-bath vaporizer 20, the temperature of the water for heat exchange is increased to increase the temperature of the gas vaporized by the vaporizer 20, so that the second temperature to be supplied to the injection valve 30 is increased, and the temperature of the fuel reaching the cylinder is increased to meet the requirement.

The control mechanism includes an air supply control device 61 and an engine control device electrically connected to each other.
Specifically, the air supply control device 61 is electrically connected to both the first temperature detection device 41 and the first pressure detection device 42, that is, the air supply control device 61 is electrically connected to the first fuel condition detection mechanism.
The air supply control device 61 receives the detected real-time first temperature value and first pressure value. Meanwhile, the air supply control apparatus 61 sends the first temperature value and the first pressure value to the engine control apparatus.
Further, after receiving the detected real-time first temperature value and first pressure value, the air supply control device 61 outputs an alarm signal when the first temperature or the first pressure is abnormal.
Specifically, a first preset pressure range is provided in the air supply control device 61, and when the first pressure is not in the first preset pressure range, the air supply control device 61 outputs an alarm signal. Wherein the preset pressure range is 0.6-0.9 MPa. That is, the air supply control apparatus 61 issues the alarm signal when the first pressure is less than 0.6Mpa and the first pressure is greater than 0.9Mpa.
The alarm signal can be sound, flashing light and sound and flashing light simultaneously to alert the staff, let the staff inspect, the concrete link of inspection goes wrong.
When first pressure is less than 0.6Mpa, cause engine fuel pressure not enough, consequently, need the staff to inspect whether the storage tank, vaporizer 20 and the connection between storage tank and vaporizer 20 etc. are problematic to in time solve the problem, guarantee whole boats and ships' normal operating.
A pressure reducing valve is arranged between the first fuel state detection mechanism and the engine to regulate the pressure of the fuel entering the injection valve 30 of the engine, so that the use safety of the engine is ensured. That is, when the first pressure is high, the pressure of the fuel entering the engine is ensured to meet the safe use requirement of the engine due to the function of the pressure reducing valve.

Specifically, the first preset temperature value comprises a low-temperature preset value and a high-temperature preset value, wherein the low-temperature preset value is 0 ℃, and the high-temperature preset value is 3 ℃.
When the first temperature is lower than the high temperature preset value, the air supply control device 61 issues an alarm signal. In the range of less than 3 ℃ and higher than 0 ℃, the damage of freezing to the connecting pipeline and the engine cannot be caused temporarily, so that only an alarm signal is sent out at the moment to remind workers of paying attention and overhauling.
When the first temperature is lower than the low temperature preset value, the gas supply control device 61 sends an alarm signal and controls the vaporizer 20 to stop operating. Since the temperature is low at this time, in order to prevent the connecting line and the engine from being frozen, the gas supply control device 61 controls the vaporizer 20 to stop operating when the first temperature is lower than 0 ℃. At the same time, the connection between the control storage tank and the gasifier 20 is disconnected. Specifically, the storage tank is connected to the vaporizer 20 through a pipeline, and the pipeline is provided with a control valve, and the control valve is electrically connected to the gas supply control device 61, so that the gas supply control device 61 can control the connection and disconnection between the storage tank and the vaporizer 20.
And a second preset temperature value is arranged in the engine control equipment, and when the second temperature is lower than the second preset temperature value, the engine stops working. Wherein the second preset temperature value is-30 ℃.
Typically, temperature control is performed at the exit of the gasifier 20, and therefore, most of the temperature reaching the injection valve 30 is sufficient. However, when the ship travels to a cold place, the environment in which the engine is located is low, and the temperature detected at the injection valve 30 is low, there is a risk of damaging the engine. Therefore, when the second temperature is lower than-30 ℃, the engine control device directly controls the engine to stop working and sends out an alarm signal.
And a second preset pressure value is arranged in the engine control equipment, and when the second pressure is higher than the second preset pressure value, the engine control equipment sends out an alarm signal and controls the engine to stop working. Wherein the second preset pressure value is 0.9Mpa.
Excessive pressure may damage the engine, and therefore, the pressure at the injection valve 30 is detected, and an alarm and a direct control stop action are performed to protect the engine.
Further, the control system also includes a display panel. The display panel is electrically connected to the air supply control device 61 and the engine control device to display the first temperature, the first pressure, the second temperature, the second pressure, and the alarm signal.

And the control system also monitors the parameters of the fuel output from the gasifier 20 up to the injection valve 30 to ensure safe use of the engine. Further, the gas supply device further includes a buffer tank disposed downstream of the vaporizer 20. The first temperature detection device 41 and the first pressure detection device 42, which are the first fuel condition detection means, may be provided on a pipe between the vaporizer 20 and the surge tank, or may be provided on a pipe between the surge tank and the engine.
