Description
The utility model relates to a kind of power engine, exactly is a kind of natural gas engine.
Along with petering out and pollution of atmosphere serious day by day of the whole world energy, developing the oligosaprobic energy has become the new problem that countries in the world face, and wherein research and development high efficiency, oligosaprobic natural gas fuel motor are subjected to the great attention of countries in the world.
Diesel engine is transformed into uses single natural gas engine and use as power and generating, abroad in some developed countries, it is ripe that the technology of powerful natural gas engine has become, is in the popularization stage, has the motor of different model and specification to come into the market towards the whole world.In, low power natural gas engine still is in the research and development stage, also has some products to come out.The price of inlet natural gas motor is high, therefore but in general,, rely on the inlet natural gas motor to come development and utilization China oil field natural gas resource, the economic benefit that it obtained is lower, under the effect of market economy rule, will finally influence the enthusiasm that the user uses.
The purpose of this utility model is to provide a kind of and is adapted on medium and small diesel engine basis, the natural gas engine of the natural gas fuel of the cheapness that forms through transformation, efficient, energy-saving and environmental protection type.
Technical solution of the present utility model is: a kind of natural gas engine, comprise body, connecting rod, distribution device, cooling system, speed control system, inlet and exhaust system, the fuel supply system magneto ignition system of unifying, it is characterized in that: described fuel supply system is suction valve, reduction valve, surge tank, pressure regulator valve, the pressure maintaining valve that pipeline connects, and is connected the firing chamber that enters in the cylinder through mixer with the intake manifold of gas handling system; Light a fire by magneto ignition system.
Below in conjunction with drawings and Examples the utility model is illustrated.
Fig. 1 is the whole structural scheme of mechanism of the utility model;
Fig. 2 connects sketch for fuel supply system;
Fig. 3 connects sketch for the magneto ignition system component;
Fig. 4 connects sketch for the speed control system component.
As seen from Figure 1, present embodiment is on the basis of 4125 diesel engines that Luoyang first tractor plant produces, and adopts the magneto ignition system transformation to form.It is transformed part and comprises gas handling system, ignition system, speed control system and combustion system, the component of transforming adopt external import key component, common of selection in domestic, develop the special purpose parts method that combines voluntarily, make the natural gas engine of present embodiment all reach coupling preferably at price, performance and structural complexity aspects.Except changing part, other such as body, connecting rod, the structure of distribution device, cooling system and inlet and exhaust system, shape and size are all basic identical with 4125 diesel engines.
Fuel supply system 1 (see figure 2) of present embodiment, suction valve 1-1, the reduction valve 1-2, surge tank 1-3, pressure regulator valve 1-4, the pressure maintaining valve 1-5 that connect for pipeline 1-10 are connected with the intake manifold 1-8 of gas handling system through mixer 1-6.Rock gas gas enters mixer 1-6 through suction valve 1-1, reduction valve 1-2, surge tank 1-3, pressure regulator valve 1-4, pressure maintaining valve 1-5, mixes with the air that passes through after air-strainer 1-7 filters.Mixed gas enters the firing chamber in the cylinder then through intake manifold 1-8, the intake manifold 1-9 (see figure 1) of gas handling system.
The swirl combustion chamber of 4125 diesel engines, i.e. cylinder cap shape invariance are still adopted in firing chamber (not providing among the figure).By reducing Piston Compression bank height, promptly adopt flat head piston or increase cylinder mat thickness (the piston head shape remains unchanged), make the compression ratio of natural gas engine be reduced to needed value.
Magneto ignition system 3 (see figure 3)s are made up of magnetogenerator 3-1, high-tension coil 3-2 and spark plug 3-3.Magnetogenerator 3-1 is connected by magnetogenerator transition piece 3-4 with the driving oil pump shaft (not shown) of 4125 diesel engines.The output conductor bundle A of magnetogenerator, B, C, D line join according to the positive pole of the high-tension coil 3-2 of the order of work of cylinder and each cylinder respectively, and the G line connects the cutoff K switch.The minus earth of high-tension coil 3-2.High-tension coil 3-2 links to each other with spark plug 3-3.
Speed control system 4 (see figure 4)s are to change a social system to form on the speed regulator 4-1 basis of 4125 diesel engines.The oil mass drag link end of former diesel engine speed regulator 4-1 connects speed governing pull bar 4-2, speed governing pull bar 4-2 connects ball one hinge assembly parts 4-3, ball pivot assembly parts 4-3 connects right angle arm 4-4, pin arm 4-4 connects leverage 4-5, leverage 4-5 connects throttle grip 4-6, and the throttle grip 4-6 closure valve block 4-7 interior with being installed in mixer 1-6 is connected.Speed-regulating signal is drawn from the oil mass pull bar of former diesel engine speed regulator, one hinge assembly parts 4-3 acts on the right angle arm 4-4 by ball, Horizontal displacement is converted into vertical displacement, through leverage 4-5 mixer throttle grip 4-6 is rotated up and down around throttle plate pin again, drive closure valve block 4-7 the gas communication sectional area in the mixer 1-6 is changed, the control mixed gas enters the flow in the cylinder.
The utility model is owing to change a social system on the basis of homemade 4125 diesel engines, critical component is quoted product of the future in the world again, pass through match test, its quality, performance have reached international most advanced level, and half of the not enough similar inlet natural gas motor of cost price has the very strong market competitiveness.The utility model is mainly used in the power source of oil-field oil pumper, substitutes the diesel engine in the 4125U diesel unit.This natural gas engine of Oilfield using can energy saving, thereby reduces the cost of petroleum production.Only with gas for oil, economic benefit that energy saving was produced.Be about 170,000 yuan every every year.This machine also can be joined the 35KW generator set, for oil field front unit provides daily production and household electricity, if calculated by 1 year 300 days, and every natural gas engine 25.2 ten thousand degree that can generate electricity every year, economic benefit is very remarkable.
