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.


Intake, induction or suction


Intake, induction or suction: The intake valves are open as a result of the cam lobe pressing down on the valve stem. The piston moves downward increasing the volume of the combustion chamber and allowing air to enter in the case of a CI engine or an air fuel mix in the case of SI engines that do not use direct injection. The air or air-fuel mixture is called the charge in any case.
Compression: In this stroke, both valves are closed and the piston moves upward reducing the combustion chamber volume which reaches its minimum when the piston is at TDC. The piston performs work on the charge as it is being compressed; as a result its pressure, temperature and density increase; an approximation to this behavior is provided by the ideal gas law. Just before the piston reaches TDC, ignition begins. In the case of a SI engine, the spark plug receives a high voltage pulse that generates the spark which gives it its name and ignites the charge. In the case of a CI engine the fuel injector quickly injects fuel into the combustion chamber as a spray; the fuel ignites due to the high temperature.
Power or working stroke: The pressure of the combustion gases pushes the piston downward, generating more work than it required to compress the charge. Complementary to the compression stroke, the combustion gases expand and as a result their temperature, pressure and density decreases. When the piston is near to BDC the exhaust valve opens. The combustion gases expand irreversibly due to the leftover pressure?in excess of back pressure, the gauge pressure on the exhaust port?; this is called the blowdown.
Exhaust: The exhaust valve remains open while the piston moves upward expelling the combustion gases. For naturally aspirated engines a small part of the combustion gases may remain in the cylinder during normal operation because the piston does not close the combustion chamber completely; these gases dissolve in the next charge. At the end of this stroke, the exhaust valve closes, the intake valve opens, and the sequence repeats in the next cycle. The intake valve may open before the exhaust valve closes to allow better scavenging.

Internet offers on a variety of vehicles

On the Internet you will find plenty of offers for the sale of cars or motorcycles. Are other machines are also sold via the Internet? Although the most popular among seeking enjoy the used cars or motorcycles, not missing the willing also to agricultural machinery or construction. Despite the fact that the probability of purchase of certain machines is really small (their price is huge), it should put an ad on the Internet to find potential customer. Websites, offering mediation between the seller and the customer also offer sales of smaller machines, such as the recently popular quads.
