engines Slide 4 Significance of lubrication: Reduction of friction
between moving and stationary engine parts Conservation of
combustion engines parts Cooling of some combustion engines parts
Minimize wear of combustion engines parts Use of lubrication:
Compression ignition engines, spark ignition engines, 4-stroke
engines, 2-stroke engines Slide 5 Mineral oils They are made by
distillation of petroleum Polo synthetic oils They are the most
common It is made by mixing mineral and synthetic oils It contains
at least 20% of synthetic part Synthetic oils They are made by
extraction of element suitable for lubrication of petroleum High
quality oil types Slide 6 Viscous classification Viscosity
resistance against liquid flowing Labelling: 15W40 15 Winter
viscous index The lowest number - the most suitable is oil for
winter traffic W Winter Oil suitable for winter traffic 40 Summer
viscous index The higher number - the most suitable is oil for
working in higher temperatures Slide 7 Productivity standard It
considers lubricating oil abilities and qualities as a complex
unit. Labelling: SJ S engine type(S spark ignition engines, C
compression engines, T 2-stroke engines) J Oil quality the further
letter it is in alphabet, the higher quality oil it is Slide 8
European standard of oil quality Oils are labelled by the
combination of letters and numbers Spark-ignition engines A,
compression engines B, lorries E Slide 9 Petrol engines A1
elementary efficiency level for modern petrol engines A2 standard
engine oils for modern petrol engines A3 high-oil quality for
modern petrol engines Diesel engines for cars B1 elementary
efficiency level for modern diesel engines B2 standard engine oils
for modern diesel engines B3 high quality oils for modern diesel
engines B4 engine oils for diesel engines of cars with straight
squirt Diesel engines for lorries E1 elementary efficiency level
for modern diesel engines E2 standard engine oils for modern diesel
engines E3 high quality oil for modern diesel engines E4 engine
oils for engines complying emission rules EURO 2 and EURO 3, along
with the possibility of extreme extensions of exchange intervals
Slide 10 Petrol engines A1 elementary efficiency level for modern
petrol engines A2 standard engine oils for modern petrol engines A3
high quality oils for modern petrol engines Diesel engines for cars
B1 elementary efficiency level for modern diesel engines B2
standard engine oils for modern diesel engines B3 high quality oils
for modern diesel engines B4 engine oils for diesel engines of cars
with direct squirt Diesel engines for lorries E1 elementary
efficiency level for modern diesel engines E2 standard engine oils
for modern diesel engines E3 high quality oils for modern diesel
engines E4 engine oils for engines complying emission rules EURO 2
and EURO 3, along with the possibility of extreme extensions of
exchange intervals Slide 11 Some producers use their own standards
for oils evaluation VW 500.00 (petrol engines) corresponds to ACEA
A3 VW 501.01 (petrol engines) - corresponds to ACEA A2 VW 505.00
(diesel engines) - corresponds to ACEA B3 Extension of exchange-
model 2000 (it is not for eastern Europe): VW 503.00 (petrol
engines) - 30000 km or 2 years VW 506.00 (diesel engines) - 30000
km or 2 years for common cars, 50000 km or 2 years for personal
cars W 505.01 (diesel engines) - 15000 km or 1 year Slide 12
Explain the meaning of standards: API SAE Slide 13 Explain the term
of viscosity Explain the following standard marking SAE: 10W30
