When you want to select a small gift, certainly a great idea is to choose a key ring or other gadget that the person receiving the gift from us can be attached to keys to the car.Very nice idea on the web, but also a fun gift for a fan of the automotive industry is a shirt with an appropriate inscription. Here we can choose a really different graphics and manufacture of t-shirts with fun prints more than one person can really surprise.
This t-shirt is a cool gift for a friend, brother or boyfriend.
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.Źródło: https://en.wikipedia.org/wiki/Internal_combustion_engine
Not surprisingly, it is a very popular way to quickly obtain necessary sometimes the vehicle.What can you do to buy certainly a good car? Very often it is recommended to select a proposed us a car to the garage. The perfect solution would be that if we had a friendly workshop where our friend after a review by a special software this car could tell us a lot about him. Experienced car mechanics unhindered see if the car has already passed through some accident or has other hidden defects, which would like to avoid a potential car owner..
