It's really annoying when a motorcycle loses power while running. I've encountered this a few times during my nearly ten years of riding. The most common issue is a clogged air filter, which restricts airflow to the engine—like trying to run while holding your breath. Another frequent problem is old or heavily carbon-fouled spark plugs, causing poor ignition and directly reducing power. The fuel system also needs attention; a carburetor or fuel injector clogged with debris can disrupt fuel supply, and poor-quality fuel can affect combustion efficiency. If the clutch is worn and slipping, the engine may rev high but the speed won't increase. I recommend starting with the basics: first check if the air filter is dirty, then inspect the spark plugs—both are easy to replace yourself. If the problem persists, it's best to have a mechanic check the fuel system and clutch.

Where is the 9-digit engine number located?

Locations to check the engine model number: exterior surface of the engine block, vehicle registration certificate, motor vehicle registration document, purchase invoice, factory certificate of compliance, operating license for commercial vehicles, vehicle purchase tax payment certificate, public security authority registration records, vehicle insurance card, and the actual engine (usually on the engine nameplate). Engine numbers are like a person's ID number, representing each vehicle and storing crucial information about it. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the engine's attributes. It is used to indicate information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are required to display the professional manufacturer's name, model, and production number. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and multiple engines can share the same model. The engine number, however, refers to the production serial number of the engine, with each engine having a unique number that cannot be duplicated. Composition of the vehicle engine number: Prefix: Includes the product series code, generation symbol, and regional or corporate code. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standardization authority. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. Suffix: Comprises symbols for structural features and usage characteristics. Tail section: Distinguishing symbol. When differentiation is required due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol. The suffix and tail sections may be separated by a hyphen (-).

What is the difference between OEM and aftermarket catalytic converters?

The difference between OEM and aftermarket catalytic converters depends on the specific product in question. It is not necessarily true that aftermarket catalytic converters are inferior to OEM ones, as some aftermarket products can perform just as well. However, most car owners lack in-depth knowledge about automotive parts, making it difficult for them to determine whether the catalytic converter they purchase meets the required standards. If a car owner is not familiar with vehicle structures, it is advisable to replace the catalytic converter with an OEM part at a 4S dealership. The quality of the catalytic converter directly affects whether the vehicle can pass annual inspections. If a catalytic converter is found to be damaged, it should be promptly repaired or replaced at a service center. Below is more relevant information: Replacing with an aftermarket catalytic converter: In fact, there is no issue with replacing it with a qualified aftermarket catalytic converter. However, the automotive parts market is a mixed bag, and without professional knowledge, it is best to opt for an OEM catalytic converter from a 4S dealership. Generally, OEM catalytic converters offer better compatibility than aftermarket ones, effectively catalyzing harmful substances in exhaust emissions. Using a substandard catalytic converter can not only lead to excessive emissions but also increase exhaust backpressure, negatively impacting the engine's power output.

Why is the engine warning light on in a Ford Mondeo?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, triggering the warning light. Fuel/oil quality issues: Failure to use fuel and engine oil as specified by the manufacturer may cause engine wear, leading to the warning light activation. Poor fuel mixture combustion: Incomplete combustion can cause engine carbon buildup or knocking. When detected by oxygen sensors and reported to the ECU, the warning light will illuminate. Spark plug failure, ignition coil issues, fuel pump malfunction, or fuel line blockages can all contribute to poor combustion. Turbocharger problems: Issues with intake boost pipes or turbochargers (especially turbocharger damage) may trigger the warning light, often accompanied by oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black exhaust smoke. Intake system issues: Air intake problems may lead to engine pipe blockages, potentially causing the warning light to illuminate. A dirty air filter that hasn't been regularly cleaned can cause intake problems. Exhaust system faults: Exhaust issues (such as rear oxygen sensor failure, catalytic converter problems, or exhaust camshaft/bearing failures) may activate the warning light. The catalytic converter is particularly vulnerable to damage from leaded gasoline, improper lubricant additives, physical impacts, or fuel system malfunctions. Anti-theft system malfunction: If the electronic anti-theft system fails or doesn't properly communicate with the engine control unit, it may prevent normal engine operation and trigger the warning light. When the engine warning light illuminates, follow these steps: 1. First check if the engine is operating normally. If there's noticeable shaking, black smoke, or other abnormalities - especially if the light is red - do not restart the engine. 2. If the engine can start, turn it off for 5-10 minutes. Then without pressing the brake (or clutch for manual transmissions), activate the ignition to the ON position to initiate system self-check. Observe if the warning light turns off after 5-10 seconds. 3. If the light remains on, visit a service center immediately. Technicians can use diagnostic tools to read trouble codes and perform targeted repairs.
