Automotive fraud network

Ads for the automotive industry are one of the most viewed by Internet users announcements relating to the exchange or purchase. The information contained in the notices contained in the virtual network often refer to many years of cars imported from abroad or after the accident. Of course, in most cases virtual proposal is only the form of information, and more content about our cars we need to look at the personal meeting. However, this does not discourage all sorts of scammers is the use of such trafficking on the Internet. Thus, by choosing Internet announcement on the interesting vehicles you need to be undoubtedly very vigilant for any kind of fraud.


In a forced (also called pressurized)

In 2-stroke crankcase scavenged engines, the interior of the crankcase, and therefore the crankshaft, connecting rod and bottom of the pistons are sprayed by the 2-stroke oil in the air-fuel-oil mixture which is then burned along with the fuel. The valve train may be contained in a compartment flooded with lubricant so that no oil pump is required.

In a splash lubrication system no oil pump is used. Instead the crankshaft dips into the oil in the sump and due to its high speed, it splashes the crankshaft, connecting rods and bottom of the pistons. The connecting rod big end caps may have an attached scoop to enhance this effect. The valve train may also be sealed in a flooded compartment, or open to the crankshaft in a way that it receives splashed oil and allows it to drain back to the sump. Splash lubrication is common for small 4-stroke engines.

In a forced (also called pressurized) lubrication system, lubrication is accomplished in a closed loop which carries motor oil to the surfaces serviced by the system and then returns the oil to a reservoir. The auxiliary equipment of an engine is typically not serviced by this loop; for instance, an alternator may use ball bearings sealed with its lubricant. The reservoir for the oil is usually the sump, and when this is the case, it is called a wet sump system. When there is a different oil reservoir the crankcase still catches it, but it is continuously drained by a dedicated pump; this is called a dry sump system.

Car - about history

The first working steam-powered vehicle was designed?and most likely built?by Ferdinand Verbiest, a Flemish member of a Jesuit mission in China around 1672. It was a 65-cm-long scale-model toy for the Chinese Emperor that was unable to carry a driver or a passenger.72122 It is not known if Verbiest's model was ever built.22


Cugnot's 1771 fardier ? vapeur, as preserved at the Musée des Arts et Métiers, Paris
Nicolas-Joseph Cugnot is widely credited with building the first full-scale, self-propelled mechanical vehicle or car in about 1769; he created a steam-powered tricycle.23 He also constructed two steam tractors for the French Army, one of which is preserved in the French National Conservatory of Arts and Crafts.24 His inventions were, however, handicapped by problems with water supply and maintaining steam pressure.24 In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam-powered road vehicle. It was unable to maintain sufficient steam pressure for long periods, and was of little practical use.

The development of external combustion engines is detailed as part of the history of the car, but often treated separately from the development of true cars. A variety of steam-powered road vehicles were used during the first part of the 19th century, including steam cars, steam buses, phaetons, and steam rollers. Sentiment against them led to the Locomotive Acts of 1865.
