Engine lubrication system — design description Lubrication system of 4-cylinder petrol engine 1. Threaded plug; 2. Oil filler neck; 3. Nut, 10 Nm; 4. O-ring; 5. To the inlet hose; 6. Pressure control valve for crankcase...
Engine oil operating conditions Depending on the operating conditions, engine oils are subjected to fairly large variable loads. Therefore, it is very important to accurately determine the effect of operating...
Oil dilution in a gasoline engine If the cylinders are over-rich and the engine rarely runs at full power or does not run at full power at all and does not have time to reach operating temperature while driving...
Engine oil viscosity Viscosity refers to the viscosity of an oil. Depending on the temperature, any oil changes its viscosity. As the temperature increases, it becomes more fluid. At the same time,...
All-weather and easy-flowing oil All-weather oils are provided for VWT4 engines. Multigrade oils have the advantage of being suitable for all temperatures (winter summer). The basis for all-season oils is a...
Scope of oil and viscosity grades Viscosity of gasoline engine oils A. Heavy-duty and easy-flowing oils according to VW-50000 B. Multigrade oils according to VW50101 or API SF or SG specification C. Seasonal oils...
Engine oil specification In modern engines, the use of HD oils is mainly allowed. HD oils are alloyed oils whose lubricating properties are greatly improved by the addition of various chemicals. These...
Engine oil consumption The oil consumption in an internal combustion engine refers to the oil that burns in the engine cylinders during its operation. And in no case, as a result of leakage from leaks...
Engine oil circulation Oil circuit diagram 1. Oil pressure sensor 2. Bypass valve (opens when oil filter is clogged) 3. Oil overpressure valve (opens at too high pressure) Through the receiving grid,...
Dynamic oil pressure control The VW T4 is equipped with dynamic oil pressure control. This means that oil pressure control is carried out and depends on the engine speed. If the engine speed drops below 2000...
Checking sensors and oil pressure Checking oil pressure sensors 0.3 bar Installed 2 oil pressure sensors, triggered at different oil pressures. The 0.3 bar oil pressure switch has brown insulation; 1.8 bar oil...
Diagnostics of malfunctions of the lubrication system Cause Elimination Method The control lamp does not blink after turning off the ignition Faulty mass pressure sensor 0.3 bar (brown insulation) Switch on the ignition, disconnect...
