Embodiment 1

[0015] Embodiment 1: a Huali miniature car that leaves the factory in 1996, and this car has traveled 80,000 kilometers. Usually, the fuel consumption is 7.5L / 100km, the uphill is weak, and the vibration and noise are loud. When fully loaded, the speed on the overpass is about 50km / h, and the oil consumption is 3L / 5000km.

[0016] After changing the new engine oil, drive 12km, add the pike brand engine oil essence manufactured by this patent, and it has a concentration of 4.0×10 -3 Vol. Modified engine oil essence, of which diamond accounts for 90%. Get this olein 15ml and add in the oil tank that 3L common gasoline engine oil has been housed, make the concentration of hyperdispersive carbon be 2×10 -5 Vol. It only needs to run for 1 to 2 minutes at idle speed to make the nano-carbon disperse evenly. At this time, you can feel that the noise is significantly reduced, the driving is much more stable than before, and the speed of the vehicle can reach 70km / h when it is fully...

Embodiment 2

[0018] Example 2: Bench test of modified engine oil. The original engine oil is SE15W / 40 engine oil, and the modified engine oil is to add 6×10 -5 Ultra-dispersed carbon with 30% diamond. The engine model is EQ6100-1, manufactured by China Second Automobile Group Corporation.

[0019] External characteristic test. Power comparison at a speed of 2700r / min: the original engine oil is 83.4kW, the modified engine oil is 88.8kW, the power is increased by 6.47%, and the fuel consumption is reduced from 426.51 to 417.51g / kW·h.

[0020] Load characteristic test. When the speed is 1600r / min and the power of the original engine oil is 52.7kW, the fuel consumption rate is 385.05g / kW·h; when the power of the modified engine oil is 58.0kW, the fuel consumption rate is only 348.58g / kW·h.

[0021] Idle speed comparison. When the engine is not adjusted in any way, the rotation speed of the original engine oil is 597r / min, while the rotation speed of the modified engine oil rises to 658r / ...

Embodiment 3

[0024] Embodiment 3: Medium-speed marine diesel engine, cylinder diameter×stroke=φ600mm×2250mm. The power per cylinder is 2360KW, the fuel consumption rate of diesel is 175g / kW·h, and the fuel consumption rate of lubricating oil is 1.4g / kW·h. Add 9×10 to existing lube -6 Ultra-dispersed nano-carbon, of which diamond accounts for 60%. The fuel consumption rate of diesel oil is reduced to 162g / kW·h, and the fuel consumption rate of lubricating oil is reduced to 0.7g / kW·h. At the same time, the anti-friction and anti-wear effect is obvious. The wear rate of the wear-resistant steel top ring is given by And no burn damage.

[0025] The modified engine oil proposed by the present invention includes gasoline engine oil, diesel engine oil and general oil for gasoline and diesel engines. It is widely used in engines of automobiles, ships, railway locomotives, airplanes and tanks, etc., all of which can save fuel and oil consumption, improve engine operation and prolong service l...

Abstract

A modified lubricating oil for engine is prepared by adding the super-dispersity carbon particles (3-6 nm in granularity) to the mineral lubricating oil. Said carbon particles contains diamond (10-98%). Its advantages are high antiwear and friction reducing effect, increasing engine power by 4-8%, saving fuel oil by 5-10% and lubricating oil by 1-4 times, and reducnig noise and HC and NOx exhaust.

Description

technical field [0001] The lubricant relates to a lubricant for an engine, which is a modified engine oil. technical background [0002] For engine lubricants, various additives are often added to mineral oil, such as detergents, anti-oxidant and anti-corrosion agents, demulsifiers, anti-foaming agents, extreme pressure anti-wear agents and oily agents. In the state of boundary lubrication, the extreme pressure antiwear agent is indispensable, and the phosphorus-based extreme pressure antiwear agent is commonly used, but it will corrode the machine parts and is not conducive to environmental protection. In recent years, nano-metal powders (Cu, Fe, Ni, Co...) and nano-SiO have also been added. 2 、Ti 3 (BO 3 ) 2 etc. are used as extreme pressure and antiwear agents, but the particle diameters of these nanoparticles are mostly in the range of 20 to 100nm, and their antiwear and antifriction properties are not good enough.
