When many people are riding bicycles, they may encounter such a situation, that is, they obviously speed up, but the feeling is still very slow, the whole car has no strength, what is going on?

Common reasons why motorcycles run weak

First, the clutch piece slips and changes the clutch piece;

Second, cleaning the carburetor and air filter;

Third, the valve is too tight, adjusting the valve clearance is about 0.06 mm;

4. The cam rocker arm is too worn and the cam rocker arm is changed.

Motorcycles, driven by gasoline engines, are two-wheeled or tricycles that are operated by the handlebars. They are light and flexible, and they travel quickly. They are widely used for patrol, passenger and cargo transportation, etc., and are also used as sports equipment. In the big direction, motorcycles are divided into street cars, road racing motorcycles, off-road motorcycles, cruise cars, and wagons.

Motorcycle running with weak maintenance knowledge

Check if the air filter is clean. It depends mainly on whether the filter element (usually a piece of sponge) is clean. If it is dusty, it can be washed with soapy water and dried before being installed. If it is this fault, the car will be squeaky, and when the throttle is added, the exhaust pipe will emit a thick smoke.

Check if the pressure of the cylinder is normal. You can screw down the spark plug, press the spark plug hole with your thumb, and then step on the pedal. If you can't press it anymore, it is normal. If you press it, there is no air spray. Out, it is the cylinder or combustion chamber leaking, see you said to check the reed valve, this car is two-stroke, can check whether the following cylinder head and cylinder are tight, the gasket is damaged, the cylinder is worn, the piston and cylinder There is a gap in the wall. If the four-stroke car checks the intake and exhaust valves for leaks, mainly check the valve clearance and turn the piston to the top dead center (the magnet has a mark on it, and align it with the mark on the engine casing, if not The spark plug can be unscrewed and placed into the spark plug hole, and the starter lever is slowly lightly pressed. When the spark plug is pushed to the highest position, the piston is at the top dead center).

If the car sounds boring and the air filter is clean, check if the exhaust gas from the exhaust pipe is strong. Use the palm to feel it at the exhaust port. If there is no force and the temperature is high, it is likely that the exhaust pipe is blocked. It can be removed for dredging or replacement, and also check if the exhaust port on the cylinder is blocked (common on two-stroke engines).

If it is a geared car, look at whether the engine speed is high and the speed does not come up. If it is, it is likely that the clutch is slipping. The clutch friction plate should be replaced. If it is an infinitely variable speed car (basically the scooter), You should check if the centrifugal disk is worn and the drive belt is worn and slips.

You said that you have changed the carburetor, but you should also check if the carburetor is properly adjusted. Check whether the air screw is screwed. The correct one should be to screw the air screw back to death for about 1.5 turns.

Finally, when checking the clearance of the valve clearance, it should be about 0.05--0.07 mm. If the clearance is too small or there is no gap, the valve will leak. The clearance will be loud and the valve and rocker will be damaged. In addition, if there is carbon deposit on the valve, the valve will not be tightly closed and leaking, but this should be removed and the cylinder head should be inspected. If it is not removed, please consult with professional maintenance personnel.

Hydraulic Cylinder

Hydraulic cylinders get their power from pressurized hydraulic fluid, which is typically oil. The hydraulic cylinder consists of a cylinder barrel, in which a piston connected to a piston rod moves back and forth. The barrel is closed on one end by the cylinder bottom (also called the cap) and the other end by the cylinder head (also called the gland) where the piston rod comes out of the cylinder. The piston has sliding rings and seals. The piston divides the inside of the cylinder into two chambers, the bottom chamber (cap end) and the piston rod side chamber (rod end / head end).

Flanges, trunnions, clevises, and lugs are common cylinder mounting options. The piston rod also has mounting attachments to connect the cylinder to the object or machine component that it is pushing or pulling.

A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. The piston pushes the oil in the other chamber back to the reservoir. If we assume that the oil enters from cap end, during extension stroke, and the oil pressure in the rod end / head end is approximately zero, the force F on the piston rod equals the pressure P in the cylinder times the piston area A:
