Abstract

The utility model relates to a secondary boosting air exchanging pump for an engine, which comprises a pump body. Two air guide pipes are installed side by side at one side of the pump body; an air plug is installed in a pump body cavity and the bottom of the air plug is fixedly provided with a push rod; a tension spring is sheathed on the push rod; the both ends of the tension spring are respectively fixedly at the lower part of the air plug and the bottom of the utility model. A one-way air inlet valve and a one-way air outlet valve whose opening and closing directions are opposite are respectively hinged on the two air guide pipes; the top of the push rod is connected with a clutch. Having the advantages of simple and compact structure, easy processing and easy installation, the utility model can enhance air inlet quantity of the engine, can make the engine exhausted air thoroughly and can decrease energy consumption.

Description

The motor secondary is strengthened scavenger pump

The utility model belongs to Vehicular engine accessory, specifically is that a kind of motor secondary is strengthened scavenger pump.

Work cycle of the motor of present various car can only intake and exhaust once, because the intake and exhaust time is short, often cause engine charge quantity not sufficient and exhaust not thorough, thereby cause oil consumption to increase, carbonizing of engine is serious, greatly reduces the power output of motor, because of present engine line finalizes the design almost, it is bigger that the overall structure of motor is improved difficulty, installs completely so install raising air input of engine by air and exhaust additional in its outside, becomes selection scheme preferably.

The purpose of this utility model be to provide a kind of simple and compact for structure, be easy to processing, easy for installation, improve air input of engine by air and make engine exhaust thorough, reduce energy consumption, make work cycle of motor realize the motor secondary reinforcement scavenger pump of twice of air inlet, twice of exhaust.

The utility model is achieved through the following technical solutions:

Be that a kind of motor secondary is strengthened scavenger pump, comprise the pump housing, the pump housing one side is installed two air pipes side by side, vent plug is installed in the pump housing chamber, vent plug bottom fixed installation push rod, suit extension spring on the push rod, the two ends of extension spring are separately fixed at the bottom of vent plug and the bottom of pump, difference opposite breather cheek valve of hinged folding direction and one-way exhaust valve on two air pipes, push rod top attachment clutch.

The clutch at described push rod top is at the top of push rod pin joint roller, and roller is placed in eccentric wheel one side that is installed on the linkage rod end, and the linkage rod the other end is installed flywheel.

The utility model is owing to solved present multiple vehicular engine deficiency of air and the halfway problem of exhaust substantially, make work cycle of motor realize twice of air inlet, twice of exhaust, and device is installed in the outside of motor, can make full use of the useful space of external engine, so have the following advantages:

1, simple and compact for structure, be easy to processing, easy for installation.

2, improve air input of engine by air, make engine exhaust thorough, reduce energy consumption.

Describe in further detail below in conjunction with accompanying drawing:

Fig. 1: the utility model example structure schematic representation.

Fig. 2: the utility model embodiment mounting structure schematic representation.

Among the figure: 1 motor, 2 outlet pipes, 3 air inlet ducts, 4 pump housings, 5 vent plugs, 6 extension springs, 7 push rods, 8 eccentric wheels, 9 rollers, 10,12 one-way cocks, 11 exhaust manifolds

Before use, air inlet duct 3 with scavenger pump is concatenated on each outlet pipe 2 of four stroke engine 1 successively earlier, and be fixed on the frame, exhaust manifolds 11 connect baffler, scavenger pump can be according to the automatic one-way cock of regulating on 11 10 of air pressure, 12 pass, open, when motor does work, simultaneously by the belt pulley on the linkage rod that belt drives with eccentric wheel 8 connects, eccentric wheel 8 is rotated, eccentric wheel 8 promotes the roller 9 on the push rod 7 again, thereby promote push rod 7, the pulling force that makes vent plug 5 overcome extension spring 7 moves right, the pump housing 4 cavity pressures increase, the one-way cock 12 of admission line is closed, one-way cock 10 on the exhaust manifolds 11 is opened, the waste gas that stockpiles in the former engine exhaust pipe is discharged from exhaust manifolds 11, scavenger pump is finished exhaust work, pressure when engine exhaust closes to an end in the cylinder reduces, at this moment the eccentric wheel 8 on the motor drive linkage rod leaves roller 9, vent plug 5 resets under the effect of extension spring 6, the one-way cock 12 that drives simultaneously on the air inlet duct 3 that resets of vent plug 6 is opened, one-way cock 10 on the exhaust manifolds 11 is closed, cylinder to motor 1 produces suction, waste gas in motor 1 cylinder is sucked in the pump housing 4 cavitys fully, produce negative pressure in motor 1 cylinder, when motor 1 changes suction stroke over to, because of motor 1 cylinder has strengthened negative pressure, so just can suck more mixed gas during motor 1 descent of piston, increased energy, do action and so forth, can continuously finish the completeness that reaches engine exhaust of replenishing, make work cycle of motor realize twice of air inlet air input of engine by air, twice of exhaust.

The one-

way cock

10,12 of scavenger pump and the kind of drive are not limited to above-mentioned two kinds of forms, according to design of the present utility model, can also be other similar devices, give unnecessary details no longer one by one.

Claims

1, a kind of motor secondary is strengthened scavenger pump, comprise the pump housing, the pump housing one side is installed two air pipes side by side, it is characterized in that installing in the pump housing chamber vent plug, vent plug bottom fixed installation push rod, suit extension spring on the push rod, the two ends of extension spring are separately fixed at the bottom of vent plug and the bottom of pump, difference opposite breather cheek valve of hinged folding direction and one-way exhaust valve on two air pipes, push rod top attachment clutch.

2, motor secondary according to claim 1 is strengthened scavenger pump, and the clutch that it is characterized in that the push rod top is that roller is placed in eccentric wheel one side that is installed on the linkage rod end at the top of push rod pin joint roller, and the linkage rod the other end is installed flywheel.
