What to Do When a Vehicle Fails the Annual Exhaust Emission Test?

Why doesn't the motorcycle speed up when the throttle is increased?

The reasons why the motorcycle doesn't speed up when the throttle is increased are as follows: Fuel line blockage: Check if the fuel line is blocked, whether the fuel filter is clogged, the spark plug gap and carbon deposits, and the strength of the high voltage from the ignition coil. If it's not strong, it could be due to a blocked fuel line. Throttle obstruction: After starting, the cold idle speed may be high, but it should normalize after warming up. If it's too high, first check if there's an issue with the throttle, such as an obstruction. Electrical issues: If the speed doesn't increase even when the throttle is fully pressed, and the engine feels weak or muffled, like riding with the choke on, check if the engine is damaged. Dirty throttle body: It could also be due to a dirty throttle body, which should be cleaned.

Should a completely dead motorcycle battery be replaced?

If the battery is not damaged and is simply out of power, there is no need to replace it, as the battery will recharge itself through normal usage. Reasons for a dead motorcycle battery: If the battery has not been maintained, the acid inside may deplete, or low/no electrolyte levels can cause power loss. How to handle a dead motorcycle battery: You can visually check if the battery fluid is low. If it is, you can add distilled water or battery electrolyte yourself. Replacement isn't necessary if the battery isn't damaged. Regular motorcycle use and minimizing prolonged headlight operation at night will prevent power loss, helping maintain battery charge for extended periods.

Do motorcycle decals need to be registered?

Whether motorcycle decals need to be registered depends on the coverage area. If the main body color of the vehicle is not changed, the decals do not cover more than 50% of the body, and they do not obstruct other vehicles' driving, then registration at the vehicle management office is not required. The following are the precautions and introduction for motorcycle modification registration: Precautions for motorcycle modification registration: For motorcycle modification registration, you should first apply at the local vehicle management office. Otherwise, the vehicle annual inspection cannot be passed. Modifications such as changing tires and rims, adding spoilers, lights, exhaust pipes, etc., are considered illegal modifications. These must be restored to their original condition to pass the inspection, and may also result in fines, license suspension, and other penalties. Introduction to illegal modifications: Illegal vehicle modifications refer to alterations to the vehicle's appearance, power system, transmission system, or braking system that exceed the legal limits allowed by national laws and manufacturer agreements, beyond the original design load capacity and functionality. This includes replacing key components. If the body color or the body/frame is replaced, the owner must register the changes at the vehicle management department within 10 days after the replacement.

What are the functions of each button on a motorcycle?

Motorcycle left and right side button functions are detailed as follows: Left side buttons of the motorcycle: Left side has horn, left/right turn signals, high/low beam headlights; right side has engine kill switch, starter switch, headlight switch. Right side buttons of the motorcycle: The lightning-shaped button on the right is the ignition switch (gear shifter for electric motorcycles); The rocker switch is the headlight switch - first position for fog lights, second position for headlights; The top left button is high/low beam switch (only works when headlights are on); The second rocker is turn signal switch; The bottom button is horn; Two green indicators on dashboard are turn signal indicators; Blue light is high beam indicator; The largest gauge is speedometer; The right gauge is fuel gauge where F indicates full.

What are the benefits of motorcycles?

Compared to cars, motorcycles are more flexible, unaffected by traffic jams, and can navigate both main roads and alleys. Their fuel consumption, maintenance, and overall costs are lower than cars, approximately one-tenth of a car's expenses. They are the best means of transportation for the middle and lower classes. Therefore, motorcycles remain popular today with no signs of being phased out. Advantages of motorcycles: Motorcycles are affordable, cost-effective, lightweight, and flexible. When comparing motorcycles to cars, the advantage depends on the travel distance. For activities within a 50-kilometer range, motorcycles have a clear advantage. For distances exceeding 50 kilometers, cars are more advantageous. Disadvantages of motorcycles: Motorcycles are 'meat wrapped in iron,' whereas cars are 'iron wrapped in meat,' meaning motorcycles have inferior safety performance.

Where is the motorcycle's catalytic converter located?

The motorcycle's catalytic converter is located inside the exhaust pipe. In most cases, the first bulge in the middle section of the exhaust pipe is the catalytic converter, which serves as the most important external purification device. Its primary function is to purify exhaust gases by catalyzing the conversion of toxic gases produced during engine combustion into non-toxic carbon dioxide, water, and nitrogen. The interior of the catalytic converter consists of asbestos fiber felt, purifying agents, a substrate, and the main catalysts: platinum, rhodium, and palladium. When high-temperature exhaust gases pass through the purification device, the purifying agents in the catalytic converter enhance the activity of three gases: CO, HC, and NOx, promoting specific oxidation-reduction chemical reactions. CO oxidizes at high temperatures to form colorless, non-toxic carbon dioxide gas; HC compounds oxidize at high temperatures into water (H2O) and carbon dioxide; and NOx is reduced to nitrogen and oxygen. These three harmful gases are thus transformed into harmless substances, effectively purifying the exhaust. Removing it is quite complex and requires cutting the exhaust pipe. Once removed, it will negatively impact atmospheric pollution.
