Fig. 1 is the structural representation of fuel gas generation unit that comprises the ignition system of the utility model.
Fig. 2 is the structural representation of the ignition system that is used for the fuel gas generation unit of the utility model.
Embodiment
In order to make those skilled in the art more be expressly understood purpose, technological scheme and the advantage of the utility model,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model fuel gas generation unit 1 comprises base 2 and is positioned at fuel gas mixer 3, ignition system 4, motor 5 and the electronic control unit (ECU) 6 on the base 2.Fuel gas mixer 3 all is connected with motor 5 with ignition system 4, and ignition system 4 is connected with electronic control unit 6.Have fuel gas inlet 7 and air inlet 8 on the fuel gas mixer 3.Motor 5 comprises suction tude 9 and outlet pipe 10.
Fuel gas generation unit 1 also comprises lambda sensor 11 and stepper motor 12, and lambda sensor 11 is vertically mounted on the exhaust elbow of motor 5.Stepper motor 12 is installed in the fuel gas inlet 7 of fuel gas mixer 3, regulates gas flow through the power adjustments valve.
As shown in Figure 2, ignition system 4 comprises spark coil 13 and spark plug 14; Spark plug 14 is preferably the iraurite spark plug; The corresponding spark coil 13 of each cylinder of motor 5.
Spark coil 13 is fixed on suction tude 9 one sides of motor 5 through support 15, is connected with spark plug 14 through high voltage wire 15.Be preferably the end that spark coil 13 is plugged on high voltage wire 15, spark plug 14 is plugged on the other end of high voltage wire 15.
Spark coil 13 can provide 4.2 ten thousand volts high-tension electricity, and has sufficiently high ignition energy, improves the reliability of igniting.Compare with traditional ignition system, because the corresponding spark coil 13 of each cylinder of motor 5, so the ignition energy loss is little, ignition advance angle is more accurate, and exempts from adjustment.
Because spark plug 14 has adopted the iraurite spark plug, can improve the power character of motor, Economy, and prolong the working life of spark plug 14.
As shown in Figure 1, fuel gas generation unit 1 also comprises magnetoelectric CMPS Camshaft Position Sensor 16, vacuum sensor 17 and cooling-water temperature sensor 18.
Magnetoelectric CMPS Camshaft Position Sensor 16 and vacuum sensor 17 are installed on the anterior gear chamber cover plate of motor 5, and it remains on the scope of 1 ± 0.25mm with the gap between the camshaft signal dish that is contained in motor 5 inside.
Cooling-water temperature sensor 18 is from threaded, and it directly is installed on the cylinder head of motor 5.
Piloted engine 5 o'clock, starter motor drives the flywheel rotation, drives simultaneously and is installed in the signal triggering disc spins on the camshaft timing gear.This signal triggering dish both can be used to declare cylinder, can measure engine speed again.When the starting speed of motor 5 when 150r/min is above, CMPS Camshaft Position Sensor 16 promptly can picked up signal.During proper functioning; ECU 6 obtains tach signal that transmits from CMPS Camshaft Position Sensor 16 and the load signal that transmits from vacuum sensor 17; After it is handled,, produce the ignition advance angle that is fit to current working point through being set in the igniting arteries and veins spectrogram among the ECU 6.ECU 6, lights a fire to each cylinder according to the work cycle of motor through ignition driver then.System has repeatedly ignition function, and promptly when motor 5 rotating speeds were lower than a certain setting value, ECU 6 can launch repeatedly ignition function, made burning more reliable, guarantees engine idle speed stability and has lower emission performance.
Between gas source and fuel gas inlet 7, have rock gas filter cleaner 19, high pressure cut-off electromagnetic valve 20, decompressor 21 and stepper motor 22.
The ignition switch of fuel gas generation unit 1 has closes, lights a fire, starts three gears.
When opening ignition switch when putting fire screen; Motor 5 is prepared to start; ECU 6 at first can control and open the elementary cut-off electromagnetic valve of rock gas, and then opens the secondary cut-off electromagnetic valve on the decompressor, and the purpose of design is before engine start like this; Gas burning system is carried out preliminary filling gas, engine start is more prone to.The time of preliminary filling gas can be set at 2 seconds or 3 seconds, if surpass set time, ECU 6 will control two closed electromagnetic valves.
When opening ignition switch to start gear, ECU 6 can control again two solenoid valves are opened, and after engine startup operation was got up, two solenoid valves can remain opening state, to satisfy the supply of rock gas.
In general, the maximum gas storage pressure of natural gas steel cylinder is 20Mpa, and the pipeline between steel cylinder and the decompressor is the pressure duct of air supply system, comes out from natural gas steel cylinder, connects valve through steel cylinder, elementary cut-off electromagnetic valve, and the high pressure filter cleaner arrives decompressor at last.Because the pressurized gas process is so this section pipeline must connect with Steel Tube Special.The force value of pressure duct can read through the pressure gauge that is installed in decompressor high pressure admission end; In addition, the staff understands the tolerance in the natural gas steel cylinder for ease, reminds the staff that steel cylinder is carried out aerating; On the steel cylinder tolerance display device can be installed; It can roughly reflect the tolerance in the steel cylinder, and when the tolerance in the steel cylinder was soon not enough, red LED light will be shinny.Get into the pressurized gas of decompressor from pressure duct, three grades of decompressions and pressure stabilization function through decompressor become the low-pressure gas that pressure only has 0.8～1.5bar.Secondary cut-off electromagnetic valve energising on decompressor is opened, and the rock gas of process second depressurized will get into three grades of relief chambers.From decompressor low-pressure fuel gas delivery outlet to the pipeline the mixer is the low pressure line of air supply system, and stepper motor power adjustments valve is equipped with in the centre, because the low-pressure gas process, so this section pipeline can connect with rubber pipe.
Fuel gas generation unit 1 also comprises (not shown) such as electronic governing system, water tank and circuit breaker.Electronic governing system can generally be to be stabilized in 1500 rpms (50Hz) or 1800 rpms (60Hz) the stabilization of speed of motor on a specific rotating speed; The rotating speed loading of automatic generator group is carried with Reduction of Students' Study Load, and makes the fluctuation of speed less than 5%.Have the cooler assembly in the water tank, be used for lowering the temperature to generator set.Circuit breaker is used for external consumer, for example electric light.
More than described the embodiment of the utility model, but those skilled in the art can make various corresponding combinations and modification to it under the situation that does not deviate from the utility model spirit, it all should belong to the protection domain of the utility model.
