A brief history of motorcycles

Since 1885 the German carrier Daimler invention manufactured the world's first car with a gasoline engine-powered motorcycles, motorcycle development has gone through 100 years of vicissitudes. The original motorcycle, existing in the real shape of the Museum of Science and Technology in Munich, Germany, is a German Daimler on August 29, 1885 patented invention of the world's first motorcycle priority. Limited to 100 years ago, when the gasoline engine is still in the low-naive status, when the vehicle is still for the carriage technology manufacturing stage, the original motorcycles motorcycle engine size and modern motorcycles are very different in appearance, structure and performance. Mi motorcycle original frame is made of wood. Judging from wood, a carpenter from the processing. The wheel is made of wood. The outer layer covered with a metal wheel. The lower frame is? A square wooden frame on which the engine is placed on both sides of each wooden frame? Small supporting wheels, whose role is to prevent the dumping stationary. As such. This car is actually a four landing. Fan-cooled single-cylinder engine, the output power by two belts and gear reduction drive, driving the rear wheels forward. Made electric motorcycle motor saddle seat, wrapped in a layer of leather. Its working volume of the engine cylinder 264mL, maximum power 0.37kW (7OOr / min), only one fifth of modern motorcycle simple. Speed ??of 12km, not much faster than walking. Ding did not spring from other cushioning device, this car was known as the "shock of bone car", it is conceivable. In the 19th century stone street driving, simply worse than execution. Although the original motorcycle is so simple, but since a motorcycle to constant change, continuous improvement, only 100 years the descendants of hundreds of millions of units of modern motorcycle.

High-speed black smoke

Symptoms for more than four or five thousand rpm the exhaust pipe smoke clear, vehicle speed power is clearly insufficient. Fault: (1) air filter or clogged air intake passage; (2) main jet cross-sectional area is too large; (3) the main nozzle hole and needle with too motorcycle engine size much space; (4) the oil level is too high. Solution: (1) clean or replace the air filter paper Filter; (2) replacement of small cross-sectional area of ??the main jet. Here to talk about the disassembly and adjustment of the carburetor. First remove the carburetor and air filter, clean or replace the filter filter, open the carburetor main jet cleaning inspection, pilot jet, the amount of air holes, adjust the float chamber oil level to normal, the oil needle transferred last card of a cell, and then refitted the carburetor and air filter, start the vehicle, the car preheat electric motorcycle motor 2min-3min, plunger height adjustment screw to adjust the idle speed minimum, and then adjust the idle air screw to adjust the engine speed up , and then to adjust the idle speed adjustment screw plunger minimum, and then adjust the idle air adjusting screw to speed up, repeatedly adjusted several times, until the lowest position of the plunger, and the engine speed up and running smoothly, that is adjusted to the optimum position. Slow fuel door, the engine speed should be smooth rise, the throttle should be no sense in any block opening, otherwise the needle to remove the card downward adjustments until satisfied.
