The lubrication system is an integral part of piston internal combustion engine and is absolutely necessary for its operation. The main significance lies in good lubricating effect of the passive resistance of moving engine parts, security of important functional nodes engine parameters and maintaining the required limits during his lifetime.
The lubrication system propane heater is designed propane heater to ensure: required coefficient of friction between the moving propane heater parts of the engine to prevent scuffing and abrasion of the material was relevant limits, heat the places that can not be cooled by the primary cooling system (pistons, bearings), dotesňovanie the contact surfaces of the combustion engine (piston ring grooves in the pistons), protection propane heater of metal engine parts against corrosion, the use of pressurized lubricating power circuit operations related propane heater to direct the operation of the engine (hydraulic tensioner hydraulic tappet, variators, etc.).
Small two-stroke engines are usually stored in the crankshaft roller bearings. The lubrication of this bearing, it is sufficient to add a small amount of oil directly to the fuel. Ratio is around the 1:20 - 1:100.
Most four-stroke and two-stroke engines have large crankshaft stored in slide bearings. The slide bearings lubrication system must ensure hydrodynamic lubrication. The principle is to create a coherent continuous boundary layer lubrication, which moving surfaces completely separated and the ongoing friction between particles and oil.
The reciprocating internal combustion engines propane heater used these methods Lubrication: Pressure lubrication - oil to the lubricated points fed under pressure through the pump. This type is further divided into: lubrication of the cabinet (wet crankcase) - sites of lubrication oil drips back into the crankcase and dry sump lubrication with - from places lubrication oil is pumped out and collected propane heater in a separate propane heater tank (air, tank engines). Spray lubrication - cylinders are lubricated oil mist, falling-bearings are lubricated with oil (very small motors). Mixed lubrication - in the case where the spray lubrication by pressure. Top lubrication - lubrication of bearings is ensured by adding oil to the fuel (two-stroke engines). Attachments and special lubrication - in the case of some occasional lubrication points (grease lubrication by Staufferových lubricators).
The lubrication system consists of the following parts: 1 - oil vapor hose to the air cleaner housing, 2 - oil filler cap, 3 - guideline levels of oil, 4 - pressure switch, 5 - oil purifier, 6 - safety valve cleaner, propane heater 7 - channel on cleaning , 8 - reducing valve, 9 - oil pump, 10 - neck suction with strainer, 11 - exit opening, 12 - partition, 13 - lower engine cover.
In an automobile engine is the most commonly used type of pressure lubrication propane heater with wet sump. Supply of oil in the bath crankcase. The basic elements are the lubricating oil pump circuit, abrasive cleaners, gentle cleaner, cooler, thermometer and barometer. The role of the overflow propane heater valve to maintain the desired pressure on the filters and coolers. Check valve maintains the setpoint pressure drop for filters and coolers. The main lubricating channel is lubricated crankshaft main bearings and crankshaft bearings. Crank bearings are lubricated propane heater oil supply from the main bearings through the grooves and holes in the crankshaft. propane heater From there, the oil gets hole in the connecting rod and the piston pin Crankshaft eye on through the sprayed cooling the inner bottom piston. Parts camshaft oil lubricates, which brings them to the camshaft bearings. Engine cylinders are lubricated by splash oil from the crankcase when rotating crankshaft, suitably arranged holes in the main connecting rod eyelets.
In recent decades, the development of the automotive industry is heading to increase performance while reducing size and weight aggregates, which leads to an increase in their mechanical and thermal stress. propane heater These factors propane heater not only affect the quality requirements of the material used for the production, but also the characteristics and quality of lubricating oil.
Monitoring propane heater the technical condition through diagnostic systems is essential propane heater for the operation of machinery and equipment according to the actual situation. Knowledge of the actual state allows, subject to the initial levels of security: more precisely define the scope of necessary repairs, eliminate unnecessary revisions and thus save considerable funds spent directly on implementation of revisions or the resources consumed by devices running-in, extended service life installations. Diagnostic system is usually made up of separate diagnostic methods, each of which is effective in diagnosing specific parts. The choice of diagnostic methods is the second diagnosed technology and its importance in the master system.
Among the various diagnostic methods include: subjective methods - a person's propane heater ability to recognize their own senses operational or fault condition diagnosed object, objective methods - are used by a variety of FVC
