A kind of energy-saving diesel machine oil and preparation method thereof
Technical field
It is a kind of energy-saving diesel machine oil and preparation method thereof the present invention relates to technical field of lubricating oil.
Background technology
Diesel engine oil is an important branch of vehicle lubricating oil, and diesel engine belongs to compression ignition engine.Diesel engine uses
The method of compressed air improves the self-ignition point that air themperature is more than diesel oil, at this moment sprays into diesel oil, diesel oil mist and air mixing again
While oneself ignition.Diesel engine is compared with gasoline engine, and the thermal efficiency is high first, and fuel economy is good, can be used
Inexpensive heavy oil.The consumption rate of fuel oil is low, and secondly power and the range of speeds are big, and the feature of environmental protection is good, CO2 emissions and gasoline
Machine, which is compared, is more about low 30-35%.Therefore application field is extensive, so the demand of diesel engine oil is growing therewith.
The energy-saving and emission-reduction of engine can be carried out by 3 kinds of main paths:Change and improve engine design, improve combustion
Expect quality and uses THE ENERGY CONSERVATION TECHNOLOGY OF LUBRICANT.Confidence level and durability test caused by being designed due to engine usually require to spend
Considerable time and very high cost, while the space that fuel mass is promoted is little, in contrast, passes through lubricant formula
Technology will be far below the cost of change engine hardware to improve the cost of fuel economy, so fuel economy engine oil
Development use, can quickly realize energy-saving and emission-reduction purpose.
Existing research shows that about 20-25% is by the friction between parts in the energy of motor vehicle fuel acting release
It is consumed, the wherein friction loss between cylinder sleeve and piston and piston ring accounts for the 45-65% of total friction head.Friction improver with
Metal surface occurs physically or chemically reaction and is adsorbed on metal surface, forms protective film, reduces friction factor, is realized to reach
Save the purpose of fuel.Therefore it is to reduce friction by adding efficient friction improver in I. C. engine oil, improves fuel warp
A kind of effective means of Ji property.
The shortcomings that prior art:Diesel engine oil does not reduce friction by adding energy-saving anti-friction agent, to fuel consumption
Greatly, waste of resource.
