oil for Daewoo Automobile - whether we need every day?
Nowadays it is difficult to imagine life without the automotive industry. Public transportation, private cars and buses at the end of the truck the goods to any kind of shops are an integral part of our everyday life. Moving cars is very comfortable, so it's no surprise that it has now become almost necessary to lead a comfortable life element. Settlement of the simplest things in a quick way, or even trips on shorter routes are really enjoyable when you have your own car or motorcycle. For many people, the same drive various means of transport is a very nice feeling. Moreover, the use of buses or cars is sometimes necessary. Carrying heavy goods they are most often carried out also by means of heavy equipment moving on the roads.
Exceptional items of agricultural machinery
Automobile is not only cars or motorbikes. Many fans machine collects all sorts of completely different equipment. They are often used to actively vehicles participating in field work. The use of such machines was quickly superseded by more modern equipment, but their nature has not changed. Often these age machines are really worth huge sums of money, and not everyone can afford to buy these stylish devices. Many of them are still working and fulfills its functions in the field. Many agricultural machines from different periods only takes on its value, and for collectors is a real gem. No wonder that organized various meetings and rallies for fans of old tractors, combines and so on.
Some systems disable alternator
Some systems disable alternator field (rotor) power during wide open throttle conditions. Disabling the field reduces alternator pulley mechanical loading to nearly zero, maximizing crankshaft power. In this case the battery supplies all primary electrical power.
Gasoline engines take in a mixture of air and gasoline and compress it by the movement of the piston from bottom dead center to top dead center when the fuel is at maximum compression. The reduction in the size of the swept area of the cylinder and taking into account the volume of the combustion chamber is described by a ratio. Early engines had compression ratios of 6 to 1. As compression ratios were increased the efficiency of the engine increased as well.
With early induction and ignition systems the compression ratios had to be kept low. With advances in fuel technology and combustion management high performance engines can run reliably at 12:1 ratio. With low octane fuel a problem would occur as the compression ratio increased as the fuel was igniting due to the rise in temperature that resulted. Charles Kettering developed a lead additive which allowed higher compression ratios.
The fuel mixture is ignited at difference progressions of the piston in the cylinder. At low rpm the spark is timed to occur close to the piston achieving top dead center. In order to produce more power, as rpm rises the spark is advanced sooner during piston movement. The spark occurs while the fuel is still being compressed progressively more as rpm rises.18
