Possible causes include intake blockage, insufficient compression pressure, valve leakage, and other factors. Below is relevant information: Three-Wheeled Vehicles: A three-wheeled vehicle is a type of cargo truck with a railed cargo compartment and three wheels. The power source can be an engine or an electric motor, primarily used for cargo transport. Three-wheelers without a cab and with a curb weight exceeding 400KG, or those with a cab and a curb weight exceeding 600KG, are classified under low-speed vehicle license plates. Those within these limits fall under motorcycle license plates. Motorized Three-Wheelers: Motorized three-wheelers are powered by either gasoline or diesel engines. Compared to electric three-wheelers, they significantly increase power, cargo capacity, and transport efficiency. The downside is that fuel emissions can cause environmental pollution, and operation requires relevant documentation from traffic authorities.

I've been riding a gasoline tricycle for many years, and there are plenty of common issues when it fails to start. A weak battery is the most common problem—insufficient power in cold weather makes it hard to start, requiring charging or a new battery. Excessive carbon buildup on the spark plug can also prevent ignition, so regular cleaning or replacement is necessary. Fuel line blockage is another major issue; a broken fuel pump or clogged fuel line cuts off fuel supply, especially after using low-quality fuel with excessive residue. Carburetor carbon buildup also causes trouble, affecting the air-fuel mixture ignition. Compression issues are less frequent, but insufficient cylinder pressure can also prevent starting. A dirty air filter restricts airflow, impacting combustion. Regular maintenance is advised—use proper gasoline and check the battery every two years. Don’t ignore minor issues; fix them promptly to avoid bigger troubles.

What are the reasons for the constant pressure loss in the Fengjun 5's brake system?

Fengjun 5's brake system frequently losing pressure can be attributed to the following reasons: 1. Air leakage in the brake oil pipe. 2. Insufficient brake oil. 3. Lack of brake lubricant. 4. Leakage in the brake master cylinder or brake wheel cylinder. 5. Wear between the hydraulic cylinder wall and piston. Below are the symptoms of pressure loss in the brake master cylinder: 1. Oil leakage at the connection between the brake master cylinder and the vacuum booster or at the limit screw. 2. Poor or ineffective braking even when the brake pedal is fully depressed. 3. The brake pedal feels soft when pressed. 4. Vehicle pulls to one side after braking. 5. Sudden brake failure. 6. The brake pedal does not return or returns slowly.

What Causes the Abnormal Noise from Newly Replaced Brake Pads?

Newly replaced brake pads produce abnormal noise due to mismatched contact surfaces, as there is a required break-in period between the new brake pads and the old brake disc. More details about brake pads are as follows: 1. Installation of new brake pads without resurfacing the old brake disc: This leads to improper fitting. If the installation is mismatched or new pads are installed without resurfacing the old disc, the new pads will directly rub against the uneven surface of the old disc, eventually causing uneven wear on the new brake pads. 2. Material issues with the brake pads: If non-genuine brake pads are used, the larger particles in the pad material can easily generate noise during braking. 3. Installation problems: Lack of lubricating paste (also known as noise reduction paste) or improperly installed brake pad shims. In such cases, reinstalling the brake pads properly should resolve the issue.

What Does Double Flash Mean?

Double flash refers to the hazard warning flasher, commonly known as "double blink" (a triangular red button with an exclamation mark inside). It is a signal light used to alert other vehicles and pedestrians that the vehicle is experiencing a special situation. When a vehicle suddenly encounters a malfunction during road driving and cannot be moved to a safe area in time, the hazard warning flasher should be activated immediately to remind passing vehicles and pedestrians to pay attention to safety and promptly call for help while waiting for rescue. If a vehicle breaks down on the highway, it should be parked in the emergency stopping lane, and the hazard warning flasher should be turned on promptly. A hazard warning sign should be placed 150 meters behind the faulty vehicle, and emergency services should be contacted immediately. The driver and passengers should wait for rescue outside the guardrail in front of the faulty vehicle.
