Interest in automotive and basic information about vehicles

Why expand their knowledge in this field, even when we do not care too much about the automotive industry? Who knows, maybe in time Moto us interested. Even if you do not want to review the basics about cars mainly because in the event of any fault, we can be aware of what has failed. Clarification of the problem is necessary to remove improperly working parts and restore the efficiency of the machine. Moreover, knowledge of what is inside the car allows faster and more efficiently operating system. Such information is useful also for this reason that many people would like to explore this issue, however, hampered by the same specialist texts Automotive quickly discouraged.


Important car insurance

Each driver must obtain the ambiguous insurance. As a result, in the event of a fault in our car accident or get compensation. This money, in many cases, are a really big contribution to the return to the previous state. What's more, we are the perpetrators of a road accident, our insurance makes wronged our people have the necessary money to carry out repairs. Insurance of each vehicle is actually mandatory. In case of detection by the police or other services of the current lack of insurance for the car, we can reckon with severe financial penalties. It is therefore aware of the periodic renewal of our insurance.


Exhaust


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.
