Description

Oil saver for petrol engine

The utility model belongs to technical field of engines

Present petrol engine, its fuel oil are directly to enter inlet manifold after Carburetor is atomized into fuel mixture, are assigned to each combustion chambers burn by inlet manifold.Owing to during engine operation, be mingled with the olesome that is not atomized in the fuel oil mixed steam, make burning insufficient, both unrestrained wasted energy source, atmosphere pollution for addressing this problem, has a kind of energy saving device that utilizes exhaust heat to improve fuel atomization effect and mixture temperature at present again.This device is to insert a coll(-tube) heater (or annular cavate heater) in outlet pipe, under Carburetor mixer is housed, and mixer is the spray chamber of porous, and is provided with independent air-strainer and air fuel ratio regulator; Coll(-tube) heater one end is communicated with mixer under the Carburetor by conduit and air fuel ratio regulator; The other end is communicated with air-strainer by conduit.During work, by the suction that engine valve actuating mechanism produced, clean air in the air-strainer is sucked in the coll(-tube) heater, high-temp waste gas heating in outlet pipe, enter in the mixer through the air fuel ratio regulator then, the low-temperature mixed gas that comes with Carburetor mixes, thereby has improved mixture temperature, make the olesome atomizing in the mixed gas, to improve the atomizing effect of fuel oil.This energy saving device is because the coiler heating is heaped in outlet pipe, and meeting carbon distribution of long duration influences exhaust, loss power.Add continuously when high-power at motor, the outlet pipe high-temperature duration is long, also can damage heater.This apparatus structure complexity, installation and maintenance trouble, cost height, starting a cold engine difficulty.

The purpose of this utility model is in order to address the above problem, to provide metal heat sink formula a kind of simple in structure, esy to use, safe and reliable to utilize exhaust heat to improve the atomizing effect of fuel oil and the gasoline-saving device of mixture temperature.

For achieving the above object, the utility model is the Carburetor 5 at motor, improves in inlet manifold 2 below the Carburetor 5 and the limiting plate 3 between inlet manifold 2 and the discharge manifold 1; Its improved technological scheme is: be the cushion block 4 of garden shape through hole in the middle of being equipped with between Carburetor 5 and inlet manifold 2, the inlet hole enlarged diameter in the middle of the inlet manifold 2 wherein is equipped with the garden cylindricality metal heat sink 6 that tightens together with limiting plate 3; The radiating fin 9 of radiator 6 is radial vertical device, and its radial end face is aimed at the trunnion oil-gas jetting direction of Carburetor 5, and bottom surface and limiting plate 3 closely touch and close.When engine operation, the exhaust heat of discharge manifold 1 will constantly be delivered on the radiator 6 by limiting plate 3, the fuel mixture that sprays down when Carburetor 5 is during by radiator 6, the olesome that is not atomized in the fuel mixture is just adsorbed by radiating fin 9, and on radiating fin 9, form oil film, oil film is met the rapid evaporation of heat and is become oil gas, enters in the mixed gas.Simultaneously, during mixed gas process radiator 6, can absorb the heat of radiator 6, mixture temperature is improved.

Be the heat-transfer rate and the caloric receptivity of raising radiator 6, the good metallic material of material selection thermal conductivity of radiator 6, as copper material, aluminium etc.Chassis 11 is arranged at the bottom of radiator 6; Chassis 11 is closely touched with limiting plate 3 and radiating fin 9 and is closed, and can increase the heat absorption area between radiator 6 and the limiting plate 3 like this, and can guarantee again has good technology to contact between radiating fin 9 bases and the chassis 11.For delaying oil film at radiating fin 9 lip-deep flow velocitys, its radiating fin 9 surface design are roughened surface, and top margin is designed to flexuose or wavy.

Garden cylindricality metal heat sink in this fuel economizer can adopt the extrusion process moulding, also radiating fin 9 can be designed to monolithic and assemble, and the garden is annotated shape metal heat sink 6 and can be fastened on the limiting plate 3 by bolt fastener 8, also can be welded on the limiting plate 3.

Though in the inlet hole in the middle of the utility model inlet manifold garden cylindricality metal heat sink is housed, because the aperture of inlet hole is strengthened, compensated the space that garden cylindricality metal heat sink accounts for substantially, make middle air inlet area of inlet manifold and former air inflow coupling.This fuel economizer makes oil inflame abundant owing to can utilize exhaust heat to improve the atomizing effect and the mixture temperature of fuel oil, under the constant situation of engine power, can use fuel oil less, reaches the purpose of fuel-economizing.Through facts have proved, the fuel-economizing of this fuel economizer energy is installed more than 12% on equal vehicle condition; And this fuel economizer is simple in structure, and is easy for installation, safe and reliable, do not influence any energy of driver, and the life-span is long, does not influence the startup of car.
