Courses
- Fuels and Lubricants Additives (30347) Course summary:
Abstract:
o Impact of vehicles emissions on environment and global warming.o Crude oil refinery processes; production of fuels and of mineral base oils.
o Basic characteristics and specifications of primary automotive fuels
(gasoline and gasoil) and bio-fuels (bio-gasoline and bio-diesel).
o Major fuel additives: composition, characteristics and func tions:
octane and cetane improvers, flow modifiers, combustion improvers, corrosion inhibitors etc.
o Tribology, friction, wear, lubrication and other important func tions of lubricants.
o Lubricant flow properties: viscosity, viscosity grades, viscosity index and viscosity modifiers.
Impact of temperature and pressure changes on viscosity.
o Production, characteristics, advantages, disadvantages and uses of mineral, synthetic and non-conventional base oils.
o Oil additives and their influence on properties and performance characteristics of finished lubricants;
chemical composition, func tions and modes of operation of major additive families (friction modifiers, anti-wear,
extreme pressure, antioxidants, detergents, dispersants, viscosity modifiers, etc.).
o Performance testing of lubricants: rig tests (such us: engine tests and gear tests), simulators
(such as: friction tests, accelerated oxidation tests and flow tests) and field testing.
o Performance levels, specifications, func tionality and characteristics of major automotive lubricants,
oils and fluids: engines oils, gear and transmission oils, hydraulic oils, brake fluids, coolants,
automotive urea solution and greases.
o Use of emission control systems in modern automobiles (such as: catalytic converters, EGR, SCR, and DPF)
and their impact on fuel and lubricant requirements, composition, characteristics and specifications.
o Analysis of fuels and lubricants: major standards and specifications, test methods, main physical
and chemical characteristics and their influence on components and performance.
o The use of lubricant analysis to monitor oil properties and to diagnose mechanical components
(engines, transmissions, etc.): advanced detection of potential mechanical problems,
investigating failure modes, condition-based and reliability-
based maintenance strategies, optimizing maintenance activities
(such as: lubricant and filter changes) and component "health" monitoring.
