How Long Can National IV and National V Vehicles Be Driven?

National IV vehicles can still be driven for at least 8 more years, while National V vehicles have at least 13 years. Based on the current pace of updating emission standards every 5 years in Europe and domestically, plus a buffer period of at least 3 years for traffic restriction policies. Definition of National IV: The National IV Emission Standard is the fourth stage of China's motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include HC, NOx, CO, PM, etc. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard controls and reduces vehicle emissions to below specified levels. Definition of National V: The National V Emission Standard, abbreviated as 'National V Standard,' has emission control levels equivalent to the European Union's fifth-stage emission standards currently in effect. The National V Standard was implemented nationwide on January 1, 2017. Cities like Beijing, Shanghai, Nanjing, and some cities in Guangdong have already begun enforcing the National V Standard.

Why does the exhaust pipe make a sound like there is water in it?

Reasons for water sound in the car exhaust pipe: caused by gasoline combustion and driving habits. Caused by gasoline combustion: The main component of gasoline is octane, which is a chemical compound of carbon and oxygen. Combustion produces carbon dioxide and water, which is the main source of moisture. The water produced by gasoline combustion is in a gaseous state. When it comes into contact with the cold exhaust pipe, some of the water vapor condenses into liquid form and remains in the exhaust pipe. Therefore, this sound is more common in winter. Caused by driving habits: Poor driving habits can lead to this issue. You can drive the car onto a slope to allow the water to gently flow out of the exhaust pipe.

Does the Jog 100 have an oil filter?

Jog 100 has an oil filter. Meaning of oil filter: The oil filter is used to remove impurities, gums, and moisture from the engine oil, delivering clean oil to all lubrication points. Function of oil filter: The oil filter can purify the engine oil, ensuring it remains clean and provides adequate lubrication to the engine. If the oil is not filtered and directly enters the lubrication circuit, it may carry contaminants to the friction surfaces of moving parts, accelerating wear and reducing the engine's lifespan.

What Causes the Idle Noise That Disappears When Accelerating?

The reason for idle noise that disappears when accelerating is a faulty carbon canister purge solenoid valve, and replacement is recommended. Function of the Carbon Canister Purge Solenoid Valve: The carbon canister purge solenoid valve serves to reduce air pollution caused by fuel vapor emissions while simultaneously improving fuel efficiency. When the engine is turned off, the vehicle's activated carbon canister begins absorbing fuel vapors evaporating from the fuel tank, securely trapping them within the micropores of the activated charcoal to prevent vapor release into the atmosphere. Hazards of Engine Idling: During engine idling, the lower temperature and pressure inside the combustion cylinders prolong fuel ignition preparation time. Coupled with reduced cylinder sealing performance, this condition easily produces knocking sounds and shortens the engine's service life.

Are There Diesel Motorcycles?

There are diesel motorcycles, such as agricultural three-wheeled cargo motorcycles that use diesel, but most motorcycles do not use diesel. The reasons are as follows: Large Volume and Weight: The inherent drawbacks of diesel engines make them less suitable for use in two-wheeled motorcycles. Firstly, diesel engines are bulky and occupy a lot of space, which the limited body space of motorcycles cannot accommodate. After installing a diesel engine, there is no room left for other auxiliary equipment. Secondly, diesel engines are also quite heavy. A diesel engine with the same power output is much heavier than a gasoline engine. Motorcycles are designed to be lightweight and easy to control, and installing a diesel engine would make the handling unbearably poor. Average Output Power: Additionally, diesel engines are low-speed engines with significant vibrations, which severely affect comfort. In terms of power characteristics, diesel engines produce high torque but generally have average output power, meaning they cannot achieve high speeds. Motorcycles are inherently lightweight and do not require such strong torque to propel them, but they do have certain speed requirements. Therefore, the power characteristics of diesel engines are not suitable for motorcycles.

Why does the motorcycle's RPM not increase when accelerating?

Motorcycle's RPM not increasing when accelerating may be caused by blocked fuel line, throttle obstruction by foreign objects, wiring issues, or dirty throttle body. Blocked fuel line: Check if the fuel line is unobstructed, whether the fuel filter is clogged, the spark plug gap and carbon deposits, and the intensity of the high voltage from the ignition coil. If the voltage is weak, it may be due to a blocked fuel line. Throttle obstruction by foreign objects: After ignition, the idle speed may be higher when the engine is cold and normalize after warming up. If it's excessively high, first check if there's an issue with the throttle, such as obstruction by foreign objects. Wiring issues: If the speed doesn't increase when the throttle is fully pressed and the engine feels weak or sluggish, it might be due to engine damage. Dirty throttle body: It could be that the throttle body is dirty and needs cleaning.
