See the impact below:
The engine valve cover gasket is a rubber gasket, its function is to seal and prevent leakage of gasoline. When the engine is running, the temperature is very high, and the leaking oil sticks to the surface of the body and slowly evaporates to produce acrid smoke. Serious oil leaks in the valve cover gasket will cause engine oil to decrease, which will affect. lubrication.
What are common symptoms of motorcycle breakdowns?
Some issues to pay attention to when using generators:
1. Use occasions
(1) The generator should be placed in an outdoor location or in well-ventilated areas of the computer room should not be close to doors, windows or air vents to prevent carbon monoxide from entering the room.
(2) Generators must notbe used near flammable and explosive materials.
(3) The generator should be placed in a dry place. If it must be installed and used in the open air, it must be protected by a canopy type building to avoid contact accidents due to humidity. .
(4) Do not use portable generators indoors, such as garages, carports, basements and enclosed spaces. Using a portable generator in these situations, even if you open windows and doors or provide mechanical ventilation, cannot prevent carbon monoxide from building up indoors, which can lead to carbon poisoning. carbon monoxide, fire or even electric shock.
2. Fuel Storage and Use
(1) Generator fuel shall be stored in a dedicated warehouse and the warehouse facilities shall comply with fire department regulations.
(2) The type of ACThe fuel used must comply with the requirements listed on the generator's instruction manual or label.
(3) Too much fuel cannot be stored in the generator, especially in the gasoline generator. If not used for 30 days, gasoline stabilizer should be added to avoid gasoline volatilization and causing an ACCIDENT. .
(4) Before adding fuel, the generator should be turned off first, and then added after the generator has cooled to prevent gasoline from gradually reaching the higher temperature parts and catch fire, causing disaster.
3. Line connection
(1) The specifications of outdoor lines must meet the requirements of the electrical load used.
(2) When using an extended wire, make sure it is well insulated from earth.
(3) The generator output wire cannot be directly plugged into the power outletant origin of the residence to supply electricity, this would cause backflow and could cause electric shock accidents to users powered by the same transformer. The correct connection is for an electrician to install a power transfer switch.
Motorcycle defects are diverse and manifest differently, but they are representative. When a motorcycle breaks down, the following phenomena often occur.
(1) Abnormal noise
With the increase of the use time of the motorcycle, improper operation, maintenance quality and the influence of natural environment, various parts and components will be damaged due to wear and tear. , damage, loosening and aging, poor contact, short circuit, open circuit and other reasons, causing it to produce sounds exceeding regulations during work. Like the sound of a knocking cylinder, superThe hiss of the fhigh-speed operation, the sound of parts scraping, the sound of gear shifting, etc.
Most motorcycle breakdowns are manifested by abnormal noises. Therefore, being able to discover the general rules and characteristics of faults from this most intuitive form of expression will bring great convenience to motorcycle fault diagnosis.
(2) Abnormal working performance
Abnormal working performance of motorcycles is a common breakdown phenomenon. Such as difficulty starting, automatic shutdown, generator not producing electricity, difficulty shifting gears, steering failure, brake failure, shock absorber failure, etc.
(3) Leak
Leakage refers to the leakage of fuel, oil, cooling water, brake fluid, etc. motorcycle, which is an obvious failure phenomenon. Leaks can easily causee overheating, burns, steering or braking failure and other faults, and must be eliminated in time.
(4) Abnormal smoke exhaust
When the engine is running, the combustion products are carbon dioxide and water vapor. If the engine combustion is abnormal, the exhaust gas will be mixed with unburned carbon particles, hydrocarbons, carbon monoxide or a large amount of water vapor, resulting in black smoke, white smoke and blue smoke. Abnormal smoke color provides an important basis for diagnosing diesel engine faults.
(5) Abnormal consumption
Abnormal consumption is also a symptom of a breakdown. Such as abnormal consumption of fuel, engine oil and cooling water, abnormal increase in oil pan oil level, etc. Abnormal fuel consumption is an important sign of poor performance.technical condition of the engine.
(6) Smell
During riding, motorcycles will have abnormal odors. Such as the burning smell of clutch friction discs, brake shoes, rubber or insulating materials, the smell of incompletely burned oil when exhausting, etc. If you notice any of these abnormal smells while driving, you should stop the vehicle to determine where the problem is.
(7) Overheating
Overheating usually manifests itself in assemblies such as engines, transmissions and brakes. Under normal circumstances, these assemblies must be maintained at a certain operating temperature, regardless of how long the motorcycle has been running. Except for the engine, if you feel an unbearable burning pain when you touch it with your hands, it means that the area is overheated. Overheating can cause serious accidents and should not be taken lightly.
