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.
The very first internal combustion engines did not compress the mixture. The first part of the piston downstroke drew in a fuel-air mixture, then the inlet valve closed and, in the remainder of the down-stroke, the fuel-air mixture fired. The exhaust valve opened for the piston upstroke. These attempts at imitating the principle of a steam engine were very inefficient. There are a number of variations of these cycles, most notably the Atkinson and Miller cycles. The diesel cycle is somewhat different.
Split-cycle engines separate the four strokes of intake, compression, combustion and exhaust into two separate but paired cylinders. The first cylinder is used for intake and compression. The compressed air is then transferred through a crossover passage from the compression cylinder into the second cylinder, where combustion and exhaust occur. A split-cycle engine is really an air compressor on one side with a combustion chamber on the other.
Previous split-cycle engines have had two major problems?poor breathing (volumetric efficiency) and low thermal efficiency. However, new designs are being introduced that seek to address these problems.
The Scuderi Engine addresses the breathing problem by reducing the clearance between the piston and the cylinder head through various turbo charging techniques. The Scuderi design requires the use of outwardly opening valves that enable the piston to move very close to the cylinder head without the interference of the valves. Scuderi addresses the low thermal efficiency via firing after top dead centre (ATDC).
Firing ATDC can be accomplished by using high-pressure air in the transfer passage to create sonic flow and high turbulence in the power cylinder.
Automotive industry - facts from Wikipedia
The automotive industry is a wide range of companies and organizations involved in the design, development, manufacturing, marketing, and selling of motor vehicles.1 It is one of the world's most important economic sectors by revenue. The automotive industry does not include industries dedicated to the maintenance of automobiles following delivery to the end-user, such as automobile repair shops and motor fuel filling stations.
The term automotive was created from Greek autos (self), and Latin motivus (of motion) to represent any form of self-powered vehicle. This term was proposed by SAE member Elmer Sperry
