Description
Technical Field
The utility model relates to an engine air intake system technical field specifically is engine air quality monitoring and processing system.
Background
Because the agricultural vehicle often works in the farmland that the dust spreads all over for a long time, the environment of the agricultural vehicle at every turn work is good and bad degree is different simultaneously, consequently, the driver often is difficult to the maintenance cycle of accurate judgement car air filter, this air inlet filter core that will lead to the agricultural vehicle is blockked up, and under the condition that air filter core blocks up and need continuously output power, this moment under the effect of pressure, some dusts of attaching to on air filter core can get into the cylinder when quick, can cause very big harm to the engine, can cause the influence to the normal output power and the fuel efficiency of engine under the serious condition.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve the problem that exists among the prior art, provide engine air quality monitoring and processing system, can be accurate learn whether air filter needs the clearance to can in time clear up air filter, guarantee air intake system's unobstructed, avoid the engine appear drawing the jar, the appearance of the not enough phenomenon of power.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:
engine air quality monitoring and processing system, including the control unit, alarm module and install dust concentration sensor, the pressure sensor in the intake duct at air filter shell rear, alarm module, dust concentration sensor, pressure sensor all with the control unit signal connection.
Preferably, the pressure sensor is installed behind the dust concentration sensor.
Preferably, the alarm module comprises an alarm indicator lamp mounted on a dashboard of the vehicle.
Preferably, the alarm module comprises a buzzer installed in the cab.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the dust concentration sensor of the utility model is used for detecting the dust concentration in the air filtered by the air filter element and sending the detection result to the control unit, thereby indirectly monitoring the amount of dust on the air filter element so as to clean in time and avoid the damage of the engine cylinder caused by a large amount of dust accumulated on the air filter element; the pressure sensor is used for detecting the air inlet pressure in the air inlet channel and sending the detection result to the control unit, so that the blockage condition of the air filter element is indirectly monitored, and the power reduction caused by the blockage of the air filter element under the condition that a driver does not know is avoided; the control unit is used for receiving signals of the dust concentration sensor and the pressure sensor, analyzing and judging the detection signals, and when exceeding a set value, the control alarm module gives an alarm to remind a driver of cleaning the air filter element, and whether the air filter element needs to be cleaned can be accurately known, so that the air filter element can be cleaned in time, smoothness of an air inlet system is guaranteed, and cylinder pulling and insufficient power of an engine are avoided.
Drawings
FIG. 1 is a schematic structural diagram of the present invention;
fig. 2 is a control schematic diagram of the present invention.
The reference numbers in the drawings: 1. an air filter element housing; 2. an air inlet channel; 3. a dust concentration sensor; 4. a pressure sensor; 5. a throttle valve.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
Example (b): as shown in attached drawings 1-2, engine air quality monitoring and processing system, including the control unit, alarm module and install dust concentration sensor 3, pressure sensor 4 in the intake duct 2 at air filter shell 1 rear, alarm module, dust concentration sensor 3, pressure sensor 4 all with the control unit signal connection. The dust concentration sensor 3 may be a VOCS dust concentration sensor.
The dust concentration sensor 3 of the utility model is used for detecting the dust concentration in the air filtered by the air filter element and sending the detection result to the control unit, thereby indirectly monitoring the amount of dust on the air filter element so as to clean in time and avoid the damage of the engine cylinder caused by a large amount of dust accumulated on the air filter element; the pressure sensor 4 is used for detecting the air inlet pressure in the air inlet channel and sending the detection result to the control unit, so that the blockage condition of the air filter element is indirectly monitored, and the power reduction caused by the blockage of the air filter element under the condition that a driver does not know is avoided; the control unit is used for receiving signals of the dust concentration sensor and the pressure sensor, analyzing and judging the detection signals, and when exceeding a set value, the control alarm module gives an alarm to remind a driver of cleaning the air filter element, and the driver can accurately know whether the air filter element needs to be cleaned or not so as to timely clean the air filter element, thereby ensuring the smoothness of an air inlet system and avoiding the occurrence of cylinder scuffing and insufficient power of an engine.
Preferably, the pressure sensor 4 is installed behind the dust concentration sensor 3.
Preferably, the alarm module comprises an alarm indicator lamp mounted on a vehicle instrument panel, and the alarm indicator lamp plays a role in guiding a driver and avoiding the situation that the driver does not know which component is in fault.
Preferably, the alarm module plays the role of reminding the driver including a buzzer arranged in the cab, and avoids the situation that the driver cannot observe a fault lamp on the instrument panel during working.
The utility model discloses when using, as shown in figure 2, detect 2 air quality superscripts in the intake duct when dust concentration sensor 3, perhaps pressure sensor 4 detects the engine normal during operation inlet pressure when unusual, the control unit can be self-defined to air filter jam, and the control unit can control alarm module and begin work this moment. The alarm indicator lamp and the buzzer in the alarm module can work simultaneously, so that a double warning effect is achieved, and the engine is prevented from working under abnormal working conditions for a long time. When the dust concentration sensor 3 detects that the air quality in the air inlet pipe does not exceed the standard, or the pressure sensor 4 detects that the air inlet pressure is normal when the engine works normally, the control unit can self-define that the air filter element is not blocked, and the system works normally at the moment.
