Di Saier German ( Rudolf Diesel ) propose the diesel engine work rule from 1882 , to 1896 makes behind first diesel engine .
Depending on the strongs point such as such well driving force , economy and endurance and so on , the application territory is more and more wide-ranging to the development that after more than 100 the diesel engine technique may be comprehensive .
Pernicious placing in proper order matter of diesel engine is a main origin creating the atmospheric pollution , and the ading gradually of significance in the wake of the environmental protection problem cut down pernicious placing in proper order matter this target of diesel engine becoming at present the significant orientation that the diesel engine in world was developed .
In the wake of the national economy development , more and more taller to the diesel engine demand , the diesel engine previously designed can not content national economy development necessaries , and for this reason , have to design manufactures the fresh generation diesel engine .
As the different inflexible driving force core , the good or bad of diesel engine performance , by different driving force machine of the immediate effect performances .
The practice makes known , and the explosive motor constantly is living very much powerful ( cooling water temperature 40 - 50 ℃s ) of cooling when emploing down , and such spare parts wornout is when turing round down quite a few -fold greatly than the regular work temperature ( 80 - 90 ℃s ) .
Through the raise explosive motor cycle effectiveness concept depart , wishs amount of heat that by means of the cooling system falls apart as far as possible more a moment , yet this certainly will be subjected to the spare parts work dependability limits .
For against ignites gas contact spare parts ( cylinder lid , cylinder case , piston and valve of a tyre and so on ) are subjected to igniteing gas intense when heating , its intensity drops , but also warmhearted stress is very great .
Hence the main mission of cooling system is gurranteing that the explosive motor is living doing below the most fit temperature condition .
The diesel engine lubricate the spare parts that to great extent series usefulness was resolved diesel engine dependability and against this correlation life .
This shows , lubricate that the system is living that diesel engine turns round is middlely taking the very much significant action .
Well lubricious is the prerequisite list that the diesel engine normality turnd round .
Since 1882 German Disaier (Rudolf Diesel) Diesel principle, in 1896 made the first diesel engine after. With its good power, economy and durability advantages, After 100 years diesel engine technology to the development of a comprehensive, application areas become more extensive. Diesel emissions of harmful air pollution is causing a major source Along with the issue of environmental protection, the growing importance of the increase, Diesel reduce harmful emissions from the goal of becoming the world today Diesel an important development direction. Along with the development of the national economy, the right engine increasingly high demand, Diesel previous design has been unable to meet the needs of national economic development, which require that the design and manufacture of a new generation of diesel engines. Various mechanical power as the core engine performance is good or bad, will have a direct impact on various dynamic mechanical properties. Practice shows that the engine cooling too often (cooling water temperature 40-50 ° C) use, its parts wear than normal temperature (80 ~ 90 ° C) when operating under good times. Raise the efficiency of the internal combustion engine cycle point of view, the hope that the cooling system through casual walk the minimal heat, But this is bound to be parts reliability constraints. Because contact with the gas components (cylinder head, cylinder, piston, valve, etc.) by a strong heating gas, Its intensity decreased, and great thermal stress. Therefore, the cooling system of the main task is to guarantee the internal combustion engine in the most suitable temperature conditions of work. Diesel lubrication system performance to a great extent determines the reliability of the engine and related components life. This shows that the diesel engine lubrication system in the operation plays a very important role. Good diesel engine lubrication is the normal operation of the prerequisites.
