The fuel supplying device for a diesel engine by mixing liquefied petroleum gas is suitable for various engines which use the diesel oil as fuel.
Description
The utility model relates to a kind of engine and mixes the mechanical type fuel supply system that burns liquefied petroleum gas, especially relates to diesel engine and mixes the mechanical type fuel supply system that burns liquefied petroleum gas.
Diesel engine is mixed the burning liquefied petroleum gas can reduce the diesel engine carbon black discharging significantly, reduces the pollution of diesel engine to atmospheric environment, can also improve the fuel structure of diesel engine simultaneously.USA I PCO company and SPI company have released diesel oil one natural gas double fuel engine at present, and its fuel supply system is to adopt Electronic Control.The patent (patent No. 98202760.5) of mechanical investigations institute of Oil Exploration in China exploitation research institute proposed a kind of with a small amount of diesel oil as light fluid, gaseous fuels such as natural gas, liquefied petroleum gas combine the double fuel feedway of controlling as the machinery of main fuel with electronics.This device mainly is to control diesel oil oil mass limiting mechanism and gas flow control valve respectively by pedal drive diesel oil pull bar or combustion gas pull bar, regulate the fuel feed amount of diesel engine, can both reliably working under various service conditions to satisfy high-pressure oil pump direct injection diesel automobile engine double fuel operating mode, it is simple in structure, and cost is low.But transient working condition poor performance such as the starting of its diesel engine, idling, sudden load change and rotating speed sudden change.When load increased, the air feed deficiency appearred; When load reduced, air feed was too much, can not fully burn, and just emits, and causes waste fuel, contaminated environment.
The purpose of this utility model be to provide a kind of can be along with engine load changes, according to the template curve of setting, regulate to mix in the mechanical linkage mode and burn the liquefied petroleum gas quantity delivered, can improve the transient working condition performance, energy savings reduces the diesel engine of environmental pollution and mixes the fuel supply system that burns liquefied petroleum gas.
The utility model purpose is achieved in that
The utility model comprises air intlet, aditus laryngis blender, LPG cyoinders, gas tank switch valve, power on/off magnet valve, decompression evaporator, lpg pipeline, diesel engine intake pipeline, throttle, diesel engine fuel oil pump, accelerator rod, diesel pipeline, diesel fuel nozzle, diesel engine body, control valve, roller, template, template lever, template lever adjustment screw, adjustable linkage pull rod, adjustable linkage pull rod adjustment screw etc.The aditus laryngis blender places on the diesel engine intake pipeline, and lpg pipeline one end is communicated with the aditus laryngis blender, and the other end is communicated with control valve.Control valve by valve seat, valve rod, place valve rod top valve, roller that stem lower portion is connected with valve rod and place valve rod and roller between back-moving spring etc. constitute.Roller rolls on the curvilinear plane of template.One end and the template lever of adjustable linkage pull rod are hinged, and the other end and throttle are hinged, and adjustment screw is equipped with in the intermediate portion.
When diesel engine is mixed the burning liquefied petroleum gas, post-decompression liquefied petroleum gas enters control valve, the liquefied petroleum gas that is come out by control valve enters in the aditus laryngis blender that is installed on the diesel engine intake pipeline, and diesel engine is mixed the fuel burning quantity delivered and can be regulated automatically according to the variation of vacuum in the aditus laryngis with change in rotational speed.Adjustable linkage pull rod pulling template with throttle linkage, according to the flow section between template curve negotiating roller control valve rod of setting and the valve seat, thereby regulate liquefied petroleum gas quantity delivered, realized that LP gas fuel quantity delivered that diesel engine mixes burning changes with the variation of load through control valve.By regulating the length that template lever adjustment screw and adjustable linkage pull rod adjustment screw are regulated template lever and adjustable linkage pull rod, realize the optimum Match between template and throttle.
The utility model compared with prior art, owing to the linear change between diesel engine throttle and the adjustable linkage pull rod is converted to nonlinear change according to the template curve setting by template, regulate thus to mix and burn the liquefied petroleum gas quantity delivered, thereby reach the preferable burning effect of mixing, have good transient working condition performance, can reduce the diesel engine carbon black discharging significantly, minimizing is to the pollution of atmosphere, and it is simple and reliable for structure, and is easy for operation, cost is low, is convenient to install.
