Motorcycles - passion for everyone?

Among those interested in the automotive industry is no shortage of people for whom motorbikes are the main area of interest. These are mainly young men, who do not yet have enough other expenses that can not afford to have a motorcycle. Although for many motorcycles is a passion for life, many a rider is forced in the future to replace your equipment, for example, disputes family car. However, the biggest enthusiasts of this equipment remain true to the end of his beloved motorcycle, so participants rallies for motorcyclists we can see a variety of people, not only of all ages, but also of different sexes. Women sometimes have the interest, though certainly more women have other, more feminine hobby.


Why not allowed to get in the car after drinking alcohol?

Driving after drinking can be dangerous even when guided bike. In the case of more complex machines, allowing to achieve a much higher speed, directing them under the influence of alcohol can be fatal. Despite the many social campaigns regarding the prohibition of driving under the influence of alcohol and strengthen penalties for drunk drivers, unfortunately, many of them still do not apply to this rule. Meanwhile, the management of a car under the influence of alcohol can lead to death of not only the driver and passengers, but also to the disappearance of completely innocent people, not even staying on the road during this event. Getting into the car under the influence of alcohol we create unnecessary risk.


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.
