Can a Motorcycle Still Be Ridden If It Has an Air Leak?

A motorcycle with an air leak should not be ridden. It can cause the vehicle to lose power, and if the air-fuel mixture is too rich or too lean, incomplete combustion in the combustion chamber will occur, leading to increased fuel consumption. Symptoms of Intake Valve Leakage: It results in insufficient power, slow acceleration, a scattered engine sound, and the engine heating up quickly; fuel consumption increases significantly, and backfiring may occur in the carburetor; starting a hot engine becomes very difficult, requiring much more throttle to start. Symptoms of Exhaust Valve Leakage: The engine sound becomes muffled; cold starts are extremely difficult; the exhaust pipe temperature becomes very high; driving feels jerky with significant vibrations and high fuel consumption.

How often is the National IV standard vehicle inspected?

New vehicles are inspected once every 6 years, once a year after 6 years, and twice a year after 15 years. Time regulations for annual inspection: The first annual inspection for a passenger car is conducted when it reaches 6 years of age. Non-operational small and micro passenger vehicles, including family cars over 6 years but under 10 years old, require an inspection every two years. For a vehicle that has just reached 6 years, the annual inspection requires driving the vehicle to the inspection station with the ID card, vehicle license, vehicle and vessel tax or tax exemption certificate, and compulsory traffic insurance policy. After passing the inspection, a certificate will be issued, and this form along with the carried documents should be taken to the relevant window to obtain the annual inspection sticker. The purpose of the annual inspection is: To check whether the engine, chassis, body, and auxiliary equipment are clean, complete, and effective; whether the car's paint is symmetrical and aesthetically pleasing; whether major general processes have been replaced and match the initial inspection records. To check whether the vehicle's braking performance, turning maneuverability, lights, exhaust pipe, and other safety factors comply with the requirements of the "Technical Conditions for Safe Operation of Motor Vehicles." To check whether the vehicle has been modified, altered, or transformed; whether all records in the vehicle license, license plate, and vehicle file match the current vehicle condition and if there are any changes; whether applications for approval, alteration, or modification procedures have been processed. To check whether the license plate printed on the vehicle, the vehicle license, and the enlarged license plate characters are damaged or illegible, and whether they need to be replaced.

Can the Horn Work Without a Relay?

No. Without a relay, thicker wires are required to connect the button switch on the steering wheel, making wiring quite challenging. Relay: A relay (English name: relay) is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) meets specified requirements. It establishes an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). Typically used in automated control circuits, it essentially acts as an "automatic switch" that uses a small current to control the operation of a larger current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in electrical circuits. Function of the Horn Relay: It amplifies the current. When a single electric horn is installed in a car, the horn button usually controls it directly. However, most cars are equipped with two types of horns, high and low pitch, or even high, medium, and low pitch electric horns to achieve a more pleasant and harmonious sound effect. When two or one electric horn operates simultaneously, the current can reach 15A or even more than 20A. If the horn button is used for direct control, the high current will quickly burn out the horn button. Therefore, a horn relay is employed.

Is it illegal to put slogans on a car?

Car body stickers are allowed, but relevant regulations must be followed. Annual inspection requirements for car stickers: During vehicle annual inspections, there are requirements for the size and placement of stickers. Reflective stickers are not allowed; secondly, the area of stickers must not exceed one-third of the total vehicle area, and stickers are not allowed on the front and rear windshields or rearview mirrors. Special vehicles such as buses, hazardous material transport vehicles, school buses, and engineering vehicles are not allowed to have any stickers except for the required signs, otherwise they will not pass the annual inspection. Legal provisions: Article 13 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates: "Motor vehicles shall not spray, paste signs or body advertisements that affect safe driving." As long as the stickers do not affect the operation of the vehicle and do not significantly alter the appearance of the vehicle, it is acceptable. For example, slogans cannot be pasted on the rearview mirror or rear glass, nor can the entire vehicle be covered with slogans to the point where the original appearance of the vehicle is unrecognizable.

Is it illegal to put advertising slogans on a car?

Unapproved and unregistered vehicle body advertisements are illegal. They become legal only after registration. However, no advertisements are allowed on the front, sides, or rear windshield of the car, as this can easily obstruct the driver's view and affect safe driving. During vehicle inspections, any advertisements on the windshield will be required to be removed; otherwise, the vehicle will not pass inspection. Additionally, painting or pasting advertisements on the vehicle body must comply with regulations and require the completion of vehicle appearance modification procedures at the vehicle management department. Advertisements on the vehicle body are only permitted on the sides of the car, outside the window glass. Advertisements are not allowed on the front and rear windshields, the front hood, or the trunk lid.

What Causes the Throttle Flap to Move When Opening and Closing the Car Door?

Throttle flap movement is likely due to the throttle motor not being properly matched. Check if the vehicle has recently experienced a power disconnection or if the throttle has been cleaned. Throttle Matching Method: The vehicle's onboard computer has an automatic learning function. Disconnect the negative terminal of the battery again, causing the ECU to lose power, then reconnect the negative terminal of the battery—sparks may occur. Under normal circumstances, this can complete the throttle matching process. Signs That the Throttle Needs Replacement: If the car's throttle operates unevenly, frequently gets stuck, and subsequently leads to issues such as failure to start, high idle speed, or poor acceleration, it may need replacement. The flexibility of the car's acceleration is closely related to the cleanliness of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine more responsive and powerful.
