摩托车动力系统改装（Motorcycle power system modification） 摩托车动力系统改装(Motorcycle power system modification) Motorcycle power system modification, so that their car more fierce, more powerful, increase the power of the general methods, there are wrong places, please riders to correct and supplement. The first part of motorcycle refit First, increase the air intake quantity the most simple method is to save money and effort for high flow air filter or direct modification of the mushroom head, modified mushroom head can make the air intake significantly increased (about 50%), but modified maybe your car will not cheer up and so on, this is because the increase of intake after mixing gas diluted by, should be adjusted according to the condition of the carburetor, adjustable gas mixture adjustment screw, low gas mixture ratio, and then adjust the oil needle adjustment speed of mixture ratio, the concentration of gas mixture is normal, can burn the spark plug to observe the color contrast adjustment. Two, modification ignition system, general domestic car ignition control angle is very small, the obvious problem is high-speed vibration easily, trembling. The igniter large modifications better point of view (0-35 is the best angle of full control, it is now I have not found), then is to use a spark plug, NGK recommended the use of iridium or platinum iridium plug, because the plug can put the ignition needle to do more fine, to produce the spark will be stronger, of course, will be more fuel-efficient, of course, this work from iridium plug can see, the effect of course is not to say, the spark plug will make the combustion more fully, and power will also increase, if the conditions can also refit pressure cap good quality point small resistance and ignition wires, such as off-road vehicles such as the use of limit modified carbon core class, so the effect will be much better, high oil return flameout problem can be solved. Three, modified exhaust system, increased intake, exhaust should also be properly modified, so that the exhaust will be discharged smoothly, and not to form a bottleneck. Methods using a drill in the exhaust behind the punch is very affordable, this method does not have to spend money, two labor saving three, the effect is good, not only increases the amount of exhaust, exhaust and no effect on the original appearance, but also increase the exhaust volume, not too loud, so as not to pay too much attention to your sir. When you first punch a hit, hit a try, until they are satisfied, ha ha. Of course, directly change the direct effect of the best, but the sound becomes bigger, then to what car, such as a sports car Prince straight row, personally feel is not too good, but the most important is the effect, appearance is based on good effect on making it more beautiful! As long as you like what you can't do, what you like is best! Four. Refit large caliber carburetor. If you have enough funds, you can refit a large caliber carburetor, but it will cost more when you change some other things. For example, 28 or 30 of the carburetor, the price of about 300 yuan, but the effect is not said, the speed is obviously much more fierce. The matching carburetor interface needs to be good and cheap Five, modified simple way transmission system is the engine rotation a little small, generally two teeth can increase, (for posterior disc more trouble), this will reduce your speed of vibration, then the engine power play is normal, the speed will improve, of course, climbing capacity will decrease. If you change the small sprocket vibration is not obvious, you can change the posterior disc method to try, in general, the posterior teeth into the original car than the small six teeth effect will be significantly better. A good chain is an important factor in ensuring that the engine is functioning normally and the power is driving the rear wheel! The chain is too serious lack of lubrication, friction, and sprocket not in a straight line. That will make the engine power is not the normal play, can choose to work better with the thickening of the chain, O type sealing ring is the best oil chain chain. Six, lightweight body, so that you can minimize the odds and ends of the car, This will reduce vibration and increase speed accordingly. When the fuel is not run long if there is no need to fill up the tank, then fill your car every day with a box full of oil to run, the corresponding fuel consumption will certainly increase the speed of course will also be reduced, ha ha. Seven, to maintain the normal tire pressure to maintain the normal tire pressure, the summer is not too big, Britain too bad, the ass is not comfortable, but also easy to tire, of course, not too small, too small friction force is too large, the engine can be difficult. Eight, increase engine displacement, if there are conditions and can change the premise, increase the cylinder, of course, will increase the power, such as 125 to 150 cylinder, and so on. Nine, modification of the driving system, like some of the car's front tires are relatively thick, such as Prince cars, etc., can be switched to a little bit smaller, will reduce the driving force of friction, but also will make the acceleration more obvious, rising speed. To change the car to the car itself characteristics. Generally speaking, the 4 impact car is so strong that you can see his piston skirt is short. Why? Because his stroke is long, and the 2 punch doesn't have that big torque. So the stroke of the crankshaft is short and the speed is high. Of course, the structure of the 2 punch also determines his high speed. Let their car more fierce, more powerful, increase power general methods, there are wrong places, please riders to correct and supplement. A load gear is a gear that transmits a power load, such as a gear in a power transmission. As far as I know, men's motorcycle engines are divided into two types, two stroke and four stroke. Among them, the four stroke engine gas distribution, common sub timing chain and top rod distribution of two, the following briefly describes the three cases of the engine. 1, two stroke engine, by rotating diaphragm and piston movement position for gas distribution. The mixture is drawn from the air filter into the crankcase and then is lowered by the piston, and the mixture gas in the crankcase is pressed into the cylinder. Therefore, the engine oil is mixed with gasoline to achieve the lubrication of the crankshaft and all friction pairs. No gear in the engine. This two stroke engine oil is involved in the combustion of gasoline, so you must use a professional two stroke engine oil, and usually a single grade of oil. 2, four stroke timing chain distribution engine, the valve on the cylinder head to open and close to match the gas, mixed gas (or air) from the air filter directly through the intake valve cylinder. The opening of the valve is opened and closed by the path of the camshaft, gear, chain, gear and crankshaft. The crankshaft is immersed in the engine oil. The oil of the engine is sucked by the oil pump from the bottom of the crankcase, and the outlet is lubricated by the friction surfaces of the friction pairs through various holes and tubes. There is big in the oil run and crank oil splash lubrication Laifu help. So there are gears in this kind of engine, that is timing chain teeth. This gear is only for cam rotation, not for load gear. This kind of engine oil, has good lubricity, good viscosity temperature, good oxidation resistance, good detergency, good anti foam, good low-temperature fluidity, and so on, are generally multi grade oil. 3, four stroke, the ejector rod distribution engine is the same as the chain distribution engine. It only uses the pole instead of the chain. The chain gear is less, and a series of cams and a set of speed gears are added. This gear is to change the crankshaft rotation angle, and match the gas distribution, that is, 2 to 1 of the teeth, crankshaft rotation 2 times, the top bar cam only turn 1 laps. This gear also acts as a gas distributor, not a load gear. The engine oil requires the same distribution engine. Gear oil, belongs to the transmission load of lubricating oil, and engine in different working environment, high torque transmission, good oil antiwear, good viscosity temperature characteristics, good anti corrosion, good anti foam, good adhesion, and so on, and its viscosity is higher than a lot of engine oil. Therefore, strictly speaking, gear oil can not be replaced by oil, and oil can not be replaced by gear oil. Original spark plug: CPR8EA-9 C--- stands for screw thread, and the diameter is: 10mm. Six corners to the edge 16mm P--- stands for: insulator protrusion R--- stands for: damping resistance type 8--- stands for: calorific value E--- stands for thread length: 19mm A --- stands for: dedicated Therefore, the full name of CPR8EA-9 is: original NGK--- thread, male diameter 10mm, thread length 19mm, six angle, opposite side 16mm, insulator protrusion, damping resistor, cold type special spark plug.
