Rotation speed of the engine in the car

Look at the issue of speed of rotation of the engine in the car

And the difference between engine speed and the last

If you notice in the case of the maximum engine speed and his speed is about 8,000 revolutions per minute, the number of endeavors, the piston per minute 4000 spm and therefore the number of runs is 2000 burning combustion stroke per minute

An average of about 33 combustion stroke per second

And can not increase the number of 33 combustion stroke in the second only after the use of fuel viability of flammable than fuel currently used stages which lead to increase the value of fuel dramatically as a result of the need for additions to increase the portability and speed of the fuel will ignite what would be the economic effect is useless completely

Where it will require the use of expensive alloys in the manufacture of internal engine parts to be able to withstand this thermal stress is the normal result of increasing the number of times the ignition rates for the internationally renowned

Has learned that the red line among the engine rpm, means that the rush of the piston to the angle of ascent has reached a major leading to a severe hit the edge of the piston approach to the wall of the cylinder .. This is a threat to the engine with time and repetition as it leads to friction Hnibr pressure and oil with the wall of the cylinder, leading over time to miss the pressure of the piston when the cycle of ignition, which weakens the power of the engine and begins to burn engine oil and starts skipping fuel mixture gas on the oil and result in the dissolved and the loss of his wife, Kmawiada to the diversion of large quantities of carbon combustion to the cylinder walls and oil ..

This point is a beautiful, clear and understandable ..

This means .. that the less the angle the piston top, it is possible to allow the engine to be its more, and this happens in a sports car designed for speed, as the volume of the piston is broad, and the movement offset the lower and upper of the piston is small, which also allows for rotation speed, the speed of stroke .. and this leads to increase the number of engine cycles ..

In some engines manufactured to withstand the force, pressure, temperature factors and torsion, the alloy parts are strong metal bear these pressures, in addition to increasing the size of factors, cooling them from the air, water, oil, and a doubling of the force by either increasing the compression ratio mixture of flammable or shipment of air through the system turbo this can increase the number of sessions, There is no doubt that these engines are expensive for that as well, such as these cars are very expensive.

For example .. we can not say for example that a car Mitsubishi Lancer normal par processing engine in a car with Mitsubishi Lancer Aivuolishn ..

And add a point .. is that the engines Frankel rotary and rare and used in some car company Mazda sports and in particular the type rx7, rx8, the design of this engine makes it easy to increase the engine .. you see that the capacity of such an engine is the size of 1300 cc - mL - mean the size of drive capacity .. Tteresl Toyota engine, but Frankel This produces 300 hp ..

One thing has surprised his people on some cars with Altaraswalmodel one may vary in the number of the sessions of the engine .. For example, a Toyota Land Cruiser, Hotfile, Model 89 M stands revs to 4000 rpm while the car Toiyotalandcrosr Pickup same model continues the number of revs to 7000 cycle, although the capacity of the engines and one which is 4000 cm 3

This is due to a design of the engine from the inside with respect to the size of the pistons and the length of the distance of displacement pistons and rapidly enter and fuel mixture leaving Amabesbb increase the number of intake valves and exhaust and either expand the sewage entering the fuel through the refrigerator .. and of course for sufficient gasoline, whether through Alkrbritor or by sprays ..

For example .. in some models of Mitsubishi cars .. find that Carpritrsearh Mitsubishi Pajero four-cylinder 2600 cc size is similar in form with Carpritr Mitsubishi Galant car when she was four cylinders and the size of 2000 cc

With this similarity .. but if we on our knees Carbritor Carpritr Mitsubishi Galant, the car will be slower and less acceleration in the number of cycles the engine .. because of the different size of the fuel spray out of the needle slots Alkrberatr small and large percentage of fuel .. calibrated in both Alcarberatren with what suits him of the volume of air that is appropriate for the size of Sahmahrk ..

In addition, the weight of the car plays a role in the acceleration of the engine when the movement .. and how long will this weight and shape of the car and Ansiabatha with air resistance .. allow the engine to increase.

I learned my brother .. that the issue of friction also plays an important role in reducing the number of revs and acceleration .. This type of alloys in terms of operating system .. Albernqat degree and type of lubrication is also .. then it could be the acceleration of the car that we use with engine oil degree w 5-30 is the same as the possibility of oil w 20-50 for the wife of Alzitin differ .. This is shown in lubrication processes that do not notice .. but the friction factor is very, very small .. when the breed and meet several aspects of it will have a significant effect ..

I wonder, my brother .. system Albernat also .. you find the tires spin by Bernqat .. We know that Albernqat is the best that can be used for the speed of movement and ease and sliding, with its minerals from the ease of movement and durability, and low factor of friction, especially when Permanent mixed with oil or grease ..

And that the use of Kdalmt Albernqat in the engines will be many times better than the use of plastic .. alloys because these alloys even if the oil is a barrier wall and Oakie and Mzelqa between them and the arms of the pistons, they also come into contact with the times .. and impair their ability and thickness with time ..

Why did not use the motor system Albernqat makers in that .. even though they use it in many ways ..

We, my brother .. when we look then to motorcycles with dual-stroke engine .. you see that the number of cycles of these engines of up to 15000 cycles or more .. what is the cause of this fictional Adorat .. Is it because the two-stroke .. light parts of the engine .. and why not use the same engines for bicycles Obaeks cars .. why not use the same engines for cars bikes ..

I learned that the reason is a matter of weight for the car .. and the question is determined for the two-stroke engines .. It was not clear ..

There is no doubt that there are reasons related to engineering and physics of metals and engineering mechanics .. set all these reasons and to answer all these questions .. There is no doubt that the people of knowledge and specialization teach .. We know little thing ..
