Abstract
The utility model relates to a device using summer diesel fuel as fuel for a diesel engine in cold winter, which comprises a main diesel tank, diesel pipe assemblies with internal heating cables, a main diesel supply passage and an auxiliary diesel supply passage. The diesel pipe assemblies are respectively arranged between the main diesel tank and a diesel inlet of an engine high-pressure diesel pump, the main diesel supply passage consists of filters with washer type heaters and two electromagnetic valves arranged at a diesel inlet and a diesel outlet of a low-pressure diesel pump, and the auxiliary diesel supply passage consists of an auxiliary diesel tank storing NO.-35 diesel fuel, the two three-way electromagnetic valves at the diesel inlet and the diesel outlet of the low-pressure diesel pump, and the diesel inlet of the high-pressure diesel pump, which are connected by common diesel pipes. The internal heating elements of the main diesel supply passage can smoothly heat NO.0 diesel fuel to above 5 degrees in cold environments so as to lead an engine to normally run, and the difficulty of long-term stall and stop can be overcome by powering the two electromagnetic valves to switch the main diesel circuit passage to the auxiliary diesel circuit passage and substituting the NO.0 diesel fuel in the high-pressure diesel pump and a diesel return pipe with the NO.-35 diesel fuel.
Description
Technical field;
The utility model relates to a kind of diesel engine and also can use winter summer diesel oil to be the device of fuel in severe cold.
Technical background:
Because " 0 " number diesel oil is stronger and price is low than-10 ,-20 ,-35 diesels, so all use " 0 " number diesel oil that adopts summer to make fuel under the diesel engine normal temperature.But arrive ambient temperature when beginning to drop to subzero when winter, the wax that " 0 " number diesel oil includes will be formed particulate and separates out, and is commonly called as " wax deposition ", and the low more wax deposition of temperature is serious more, finally can stop up filter element and make the motor oil-break flame-out.Make start function normally to start operation just must to adopt low grade diesel oil such as lower-10 ,-20 ,-No. 35 of wax deposition temperature spots be fuel, because label low price more is just expensive more, have again under the same operating conditions, it is lower more than 15% than adopting-No. 35 diesel oil fuel consumption to adopt " 0 " number diesel oil, and one liter of " 0 " number diesel oil of comprehensively measuring and calculating is than one liter " 35 " number more than diesel oil cost saving 2 yuans.
More than the pre-hot product of existing oil circuit can be spent " 0 " number diesel oil preheating to 5, but when temperature drops to below-20 degree, during the engine dies overlong time, accumulating in " 0 " number diesel oil that reaches in the return tube in the high pressure oil pump housing will highly condense and can not be released by low pressure fuel pump, the whole heating of oil feed line can not be sucked pressure duct by the high pressure oil pump plunger, even therefore can not make " 0 " number diesel oil smooth ato unit under severe cold environment.
Summary of the invention:
The utility model provides that a kind of to make diesel engine also can adopt " 0 " number diesel oil under severe cold environment be the technology and the product of fuel.
Present technique and product are the main fuel tanks that " 0 " number diesel oil arranged by deposit certainly between engine high pressure oil pump filler opening, the oil pipe assembly that make the built-in PTC function of each section heating tape, the heating filter cleaner that is provided with the gasket type heater is through being located at the main oil supply gallery of low pressure fuel pump into and out of two three-way magnetic valves formations of hydraulic fluid port, the small-sized drop tank that-No. 35 diesel oil are arranged with deposit through be located at low pressure fuel pump into and out of two three-way magnetic valves of hydraulic fluid port to the high pressure oil pump filler opening, form by the secondary oil supply gallery that plain tubing connects and composes.
Its working procedure is as follows;
Main oil supply gallery is with built-in heating element of the present utility model under severe cold environment, can smoothly " 0 " number diesel oil be heated to more than 5 degree, make normal working of engine, when motor needs flame-out for a long time the parking, main oil channel channel is switched to the auxiliary oil circuit passage for two solenoid valve energisings, with-No. 35 diesel oil replace out accumulate in the high pressure oil pump housing and return tube in " 0 " number diesel oil, can solve an above-mentioned difficult problem.
Description of drawings:
Fig. 1, be that the utility model diesel engine severe cold uses summer diesel oil to be the oil-way system schematic representation of the device of fuel winter.
Fig. 2, be that the utility model diesel engine severe cold uses summer diesel oil to be the interior heating oil pipe assembly figure of the device of fuel winter.
Specific implementation method:
With reference to Fig. 1, it is the main fuel tank 1 that " 0 " number diesel oil is arranged by deposit certainly as the device of fuel that the utility model diesel engine severe cold is used summer diesel oil winter, the oil pipe assembly of making to the built-in PTC function of each section heating tape between the engine high pressure oil pump filler opening 92, the heating filter cleaner 4 that is provided with gasket type heater 3 advances through being located at low pressure fuel pump 6, the main oil supply gallery that two three-way magnetic valves 5 of oil outlet constitute, the small-sized drop tank 7 that-No. 35 diesel oil are arranged with deposit, advance through being located at low pressure fuel pump 6, two three-way magnetic valves 5 of oil outlet are made up of the secondary oil supply gallery that plain tubing 8 connects and composes to high pressure oil pump filler opening 9.
Its working procedure is as follows;
Main oil supply gallery is with built-in heating element of the present utility model under severe cold environment, can smoothly " 0 " number diesel oil be heated to more than 5 degree, make normal working of engine, when motor needs flame-out for a long time the parking, give two solenoid valves 5 energisings, main oil channel channel is switched to the auxiliary oil circuit passage, replace out with-No. 35 diesel oil and accumulate in " 0 " number diesel oil that reaches in the high pressure oil pump housing in the return tube, can solve an above-mentioned difficult problem.
Use winter summer diesel oil to constitute with reference to Fig. 2, the utility model diesel engine severe cold as the interior heating oil pipe assembly of the device of fuel joint 10, automobile specified oil pipe 11, built-in PTC function heating tape 12, tailor-made oil pipe joint 13, power connection 14 by center hole, can be required by each section of automobile oil circuit length, PTC function heating tape and oil connection and automobile specified oil pipe are prefabricated into one in factory, substitute former car oil pipe when being convenient to install.
