Mercedes smoking exhaust Virtual car for real money
The Internet is full of all kinds of automotive ads. They concern mainly the sale of used cars. Is it worth it to use the online services when looking for a car? It is certainly a very good solution if you do not have stalked the offer on the eye. You have to admit, however, that the majority of websites of the car in a good condition and at a reasonable price "spread" very quickly and to hunt down the network a good car you have to try hard. On the other hand, among the announcements automotive missing SELL they offer us to buy a good car, and really the facts are quite different.
Why you need to be careful selecting foreign used car?
Acquisition of foreign used cars from Germany or France is very popular. When buying a car from abroad we have to be careful if the seller does not deceive us, because there is no shortage of vehicles which, for example, have accidents and are sold as accident-free. Then the car can really be in bad shape, although aesthetically looks good and inconvenience are covered. This creates a really big risk and it is worth to choose the service of your friends in this regard. Imports of cars from abroad is often a way to earn a certain amount of money, so a lot of people lead such activities. So let's go to a friend or a person with a command when you plan to buy this car.
Other cycles
Other cycles
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.
