Car insurance - what you should know?

As you know, every car owner is obliged to insure your car. The fee, which you need to bring in this respect, however, is dependent on many factors. First of all, a key criterion in this regard is the model and brand of the insured car. This is the value of the car depends on the amount of possible compensation. It is also important that in which he was made our car and how many kilometers is already on the meter. It is known that with the number of kilometers traveled risk of defects is increasing. Nevertheless, important in this regard is how old is the owner of the car, because the amount of insurance premium depends on the metric of the holder of the car.

Power or working stroke

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.


Navigation - increasingly willing to be used by drivers

Although the market there are a lot of gadgets, which are available to the driver, most people reaching for automotive technical innovations selects navigation. It is without a doubt the most popular device, which allows for maintaining the route, even without knowing the map. What's more, most of the satellite navigation sets us some runs and we can decide, according to which we will go. Most people reach for this little device, above all, because it allows not to get lost in an unknown area; by navigation you can also quickly reach the destination in many cases. Fashion for having such a gadget automotive lasts for several years and so far, you can expect that these articles will continue to be very readily bought by drivers.
