  • Take a look at the new motorcycle safety technology

    A German technology company is testing new motorcycle safety technology that can prevent motorcycles from colliding or overturning. The technology being tested is not new and similar to the technology used by astronauts in zero-gravity navigation. The Company's anti-skid system uses a device similar to a car airbag to provide external lateral force when the tire of the motorcycle loses traction. In other words, when a bicycle begins to slide and fall, the pressurized gas propeller will push down and straighten the motorcycle so that it does not roll.

    The thruster counteracts the sliding wheel, allowing the rider to re-stabilize the bike. The gas is pushed out of the propeller of the motorcycle, more or less like the spacecraft will use the propeller to change direction. Here, the sliding wheel is subjected to the thrust to straighten the motorcycle and give the rider some traction to avoid the disaster.

    The only downside is that the system is like a car airbag and can only be used once. Once the gas propulsion system is started, the system will have to be reinstalled. But so far, the system is still in beta, so when it comes to the actual use of mass-produced motorcycles, the company may find new ways to make it reusable.

  • How to prevent spontaneous combustion of motorcycle

    Since the metal part of the entire frame of the motorcycle can be called the negative pole, that is, the grounding iron, if some of the wires are accidentally contacted with the metal part, a short circuit will occur. The car with good condition is usually burned, but some cars may even be connected. The fuses are gone, they are all connected directly by the line. The large current generated during the short circuit will burn the rubber and cause spontaneous combustion.

    The part that causes oil leakage is generally the oil path from the fuel tank to the carburetor. The rubber of the joint is aging, and the seal of the carburetor interface is damaged and aging, which will lead to external oil leakage. The hot summer will further promote the leakage of gasoline. Volatilization, combined with the previous several predisposing factors, can easily lead to spontaneous combustion.

    How to prevent spontaneous combustion of motorcycle?

    1.Always check whether the connecting posts and the connectors are loose and rusted;

    2.Check whether the insulation around the flammable parts has insulation and cracking;

    3.Check whether the wire connection has a virtual weld off;

    4.Check the appearance of the oil circuit for leaks and heavy gasoline smell;

    5.Do not abuse the accelerating pump when parking, to prevent excessive gasoline injection into the carburetor throat to increase leakage;

    6.Prevent the motorcycle from being placed in a closed and non-ventilated space for a long time;

    7.Clean the motorcycle in time

  • What are the reasons for spontaneous combustion of motorcycle

    1. High voltage circuit is easy to induce spontaneous combustion

    The high-voltage ignition system of motorcycles has a voltage of up to 10,000 volts. If the high-voltage line and the high-pressure cap are used for a long time, the rubber is aged and the pressure resistance is reduced, so that the high-voltage electricity cannot be restrained, resulting in accidental flashover in a weak place. The phenomenon of burning cars caused by high-voltage electric leakage is common in the working or driving state of motorcycles. It is the most dangerous fault. It should be checked frequently, maintained frequently, and beware of high-voltage leakage.

    2. High current parts are easy to induce spontaneous combustion

    The starting circuit of the motorcycle, the charging circuit, the headlights, the horn and other wires belong to a large current range, and the current transmitted during operation is relatively large. If a virtual connection occurs in this part of the circuit, the contact resistance will increase, and high heat will be generated here. The burned wire is sheathed, thereby generating an accidental spark-induced spontaneous combustion. If these wires are not maintained for a long time, friction with each other may cause damage to the insulating rubber, which may cause accidental flashover to induce spontaneous combustion.

  • The SAE standards for performance of motor oils

    Engine oil currently has a world-wide classification standard. General gasoline engine oil packaging will be marked with the classification of these two general standards.

    One type of standard is the SAE standard - classified by viscosity

    SAE is the acronym for Society of Automotive Engineers: Society of Motor Engineers of the United States (the country is still very strong, his standard is global). Founded in 1905, it is the largest automotive engineering academic organization in the world. Research objects are cars, trucks and construction vehicles, aircraft, engines, materials and manufacturing. The standards established by SAE are authoritative, widely used in the motorcycle industry and other industries, and a considerable part are adopted by global standards. As an important part of the gasoline engine oil, of course, there are professional SAE classification.

    The winter oil grades for the SAE lubricant viscosity classification are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for winter. The smaller the number before W, the lower the low temperature viscosity and the better the low temperature fluidity. The lower the minimum temperature,

    The oil grades of the SAE lubricants in summer are: 20, 30, 40, and 50. The higher the number, the greater the viscosity, and the higher the applicable maximum temperature.

    SAE Lubricant Viscosity Classification of winter and summer general oil brands are: 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, 10W-50, 15W-20, 15W -30, 15W-40, 15W-50, 20W-20, 20W-30, 20W-40, 20W-50, the smaller the number represents the winter part (lower minimum temperature is applicable), the larger the number represents the summer part (The higher the applicable maximum temperature), the greater the applicable temperature range.
