oil for Chrysler Tuning the car in his own garage
Tuning cars gives them the most suitable vehicles sporty look. Many cars and motorcycles looking for faster and more efficient machine when we add a few elements. There's no denying that the tuning is often a form of gain recognition in society or gain friends, especially among younger drivers. Almost every young boy wants to have a car, but not everyone can afford it. Some elements, however, can replace their own. With the necessary financial resources should in fact invest in tuning parts, and then personally carry out improvement of our vehicle.
Historical design
Historical design
Dugald Clerk developed the first two cycle engine in 1879. It used a separate cylinder which functioned as a pump in order to transfer the fuel mixture to the cylinder.6
In 1899 John Day simplified Clerk's design into the type of 2 cycle engine that is very widely used today.13 Day cycle engines are crankcase scavenged and port timed. The crankcase and the part of the cylinder below the exhaust port is used as a pump. The operation of the Day cycle engine begins when the crankshaft is turned so that the piston moves from BDC upward (toward the head) creating a vacuum in the crankcase/cylinder area. The carburetor then feeds the fuel mixture into the crankcase through a reed valve or a rotary disk valve (driven by the engine). There are cast in ducts from the crankcase to the port in the cylinder to provide for intake and another from the exhausst port to the exhaust pipe. The height of the port in relationship to the length of the cylinder is called the "port timing."
On the first upstroke of the engine there would be no fuel inducted into the cylinder as the crankcase was empty. On the downstroke the piston now compresses the fuel mix, which has lubricated the piston in the cylinder and the bearings due to the fuel mix having oil added to it. As the piston moves downward is first uncovers the exhaust, but on the first stroke there is no burnt fuel to exhaust. As the piston moves downward further, it uncovers the intake port which has a duct that runs to the crankcase. Since the fuel mix in the crankcase is under pressure the mix moves through the duct and into the cylinder.
Because there is no obstruction in the cylinder of the fuel to move directly out of the exhaust port prior to the piston rising far enough to close the port, early engines used a high domed piston to slow down the flow of fuel. Later the fuel was "resonated" back into the cylinder using an expansion chamber design. When the piston rose close to TDC a spark ignites the fuel. As the piston is driven downward with power it first uncovers the exhaust port where the burned fuel is expelled under high pressure and then the intake port where the process has been completed and will keep repeating.
Later engines used a type of porting devised by the Deutz company to improve performance. It was called the Schnurle Reverse Flow system. DKW licensed this design for all their motorcycles. Their DKW RT 125 was one of the first motor vehicles to achieve over 100 mpg as a result.14

Old models 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.
