Description

The composition of Wankel RC configuration lubricating oil

Technical field

The invention belongs to Wankel engine lubricating oil field, the particularly composition of Wankel RC configuration lubricating oil.

Background technology

Wankel RC configuration belongs to the one without piston return four-stroke internal combustion engine.It is placed forms therebetween by comprising a triangular rotor in cocoon shape shell.Always be divided into three working spacess between the inside of cylinder, these working spacess of rotor turns are also in motion; Different positions successively in cycloidal cylinder body completes and carries out, compresses, do work (burning) and be vented Four processes.Difference between rotor and a housing ancient piece of jade, round, flat and with a hole in its centre, as internal combustion chamber, is rotated by the pressure-driven rotor of gas expansion.Wankel engine the same as ordinary internal combustion engine must in succession form four working process in its working spaces.When leg-of-mutton rotor being placed on the centre of circular shell, working spaces can not change on volume along with the rotation of the swelling pressure inner rotator of housing.Even if empty combustion gas mixture is lighted there, the swelling pressure of combustion gases also only act on the middle part of rotor, can not produce rotation.The inside cylindrical of Here it is housing is designed to runner outer shape, and be arranged on the reason together with the composition of the rotor on excentric shaft.Rotor often rotates one week, working spaces's volume change twice, thus completes four working process of oil engine.

Meanwhile, moving along with the oval-shaped shell of motor body circumference in engine rotor summit, can keep the contact with the output shaft gear be centered around on an eccentric track at motor body center.The track of triangular rotor is determined with a timing gears.Phasing gears comprises the ring gear be arranged on inside rotor and the outer rotor be arranged on excentric shaft.If there are three teeth inside rotor gear, rotor and axle rotating ratio are set as 1:3; Compared with excentric shaft, rotor has longer rotation period.When rotor turns one week, eccentric shaft turns three enclosed.When motor speed is 9000 revs/min, the rotating speed of rotor is 3000 revs/min.Therefore require this kind of engine oil have excellent peace and quiet dispersive ability, sticky-temperature characteristics, base number retentivity, acid neutralization capacity, good resistance to high temperature oxidation, anti-nitrated, wear-resistant, anti-shearing, preservative property, cold cranking capacity are good, ash content is low, smoke evacuation less, corrosion-free to moving parts, be applicable to high speed, high pulling torque, high working condition; Simultaneously noise low, vibrate little, not easily produce the features such as carbon deposit.

Summary of the invention

The object of this invention is to provide a kind of there is excellent peace and quiet dispersion effect, viscosity-temperature characteristics, base number retentivity, acid neutralization capacity, good resistance to high temperature oxidation, anti-nitrated, wear-resistant, anti-shearing and anti-friction and corrosion-resistant, cold cranking capacity is good, ash content is low, corrosion-free to moving parts, be applicable to high speed, high pulling torque, high working condition, the composition of the Wankel RC configuration lubricating oil that Wankel engine can work long hours.

For above-mentioned technical problem, the present invention adopts following technical scheme:

The composition of Wankel RC configuration lubricating oil, adopt oil based on poly-internal olefin and trihydroxymethylpropanyl ester compound, coordinate multiple composite additive, the mass percent of each component is:

Component	Mass percent content
		Base oil	Surplus
Purification agent	4.0％～6.0％
		Dispersion agent	2.0％～5.0％
Strengthening agent	2.0％～3.0％
		Antioxidant preservative	0.5％～1.5％
Rust-preventive agent	0.5％～1.0％
		Defoamer	0.005％～0.01％
Oxidation inhibitor	0.5％～1.0％
		Auxiliary agent	0.5％～0.8％
Friction improver	2.0％～4.0％

The mass percent summation of each component is 100%.

Base oil is poly-internal olefin and 55% ~ 45% trihydroxymethylpropanyl ester compound of mass ratio 45% ~ 55%.

Purification agent is the high base number calcium alkylbenzenesulfonate of mass ratio 45% ~ 55% and the low alkali value calcium alkylbenzenesulfonate compound of 55% ~ 45%.

Dispersion agent is the low nitrogen polyisobutene succinimide T155 of mass ratio 25% ~ 35%, the diene base succimide of 25% ~ 35% and 50% ~ 30% high nitrogen boronation polyisobutylene-bis-succinimide compound; The mass percent summation of three components is 100%.

Strengthening agent is calcium sulfenyl phenolate T115A and 55% ~ 45% high nitrogen polyisobutene succinimide compound of mass ratio 45% ~ 55%.

Antioxidant preservative is the sulphur phosphorus Zhong Ji zinc salt compound of the two octyl group basic zinc salt T203 and 55% ~ 45% of sulphur phosphorus of mass ratio 45% ~ 55%.

Rust-preventive agent is the benzotriazole of mass ratio 45% ~ 55% and the alkenyl succinic acid half ester compound of 55% ~ 45%.

Defoamer is the phenyl-chloride methyl-silicone oil of mass ratio 45% ~ 55% and the ethyl silicon oil compound of 55% ~ 45%.
