Can Beijing National VI Diesel Vehicles Be Licensed?

Beijing National VI diesel vehicles cannot be licensed. The following is extended content: 1. Phase V Emission Control Requirements: "Limits and Measurement Methods for Exhaust Pollutants from Compression Ignition and Gas Fuel Positive Ignition Engines and Vehicles (China III, IV, V Phases)"; "Limits and Measurement Methods for Exhaust Pollutants from Compression Ignition and Gas Fuel Positive Ignition Engines and Vehicles (Bench Test Method)"; "Limits and Measurement Methods for Exhaust Pollutants from Heavy-Duty Vehicles (On-Board Method)". 2. Enterprise Declaration Requirements: Enterprises declaring for the environmental protection catalog must continue to follow the requirements stipulated in "Notice on the Declaration Requirements for Heavy-Duty Diesel and Gas Vehicles (Engines) for the Beijing Environmental Protection Catalog" and "Notice on Relevant Regulations for Heavy-Duty Vehicle Emission Control". At the same time, enterprises must strengthen production management to ensure that sold vehicles stably meet the standards. 3. Heavy-Duty Diesel Vehicle Requirements: New heavy-duty diesel vehicles (such as buses, sanitation vehicles, tourist vehicles, postal vehicles, dump trucks, shuttle buses, school buses, airport buses, etc.) used within the administrative area of Beijing should be equipped with wall-flow particulate filters (DPF). 4. Vehicle Registration Requirements: Vehicle models that do not comply with Phase V regulations will not be processed for vehicle registration. Heavy-duty diesel vehicles meeting Phase IV emission standards purchased before August 1, 2015 (based on the date of the purchase invoice) or transferred from other provinces to Beijing before that date (based on the transfer registration date in the vehicle registration certificate) can continue to be processed for vehicle registration.

Design characteristics: BMW sedans feature distinctive body styling with round headlights paired with rectangular radiator grilles, creating a unique style. 2. Powertrain: All BMW models are rear-wheel drive. The rear-wheel drive configuration allows for a 50-50 weight distribution between front and rear, providing better performance during high-speed cornering and straight-line driving compared to front-wheel drive vehicles.

What is the working principle of a rotary engine?

Working principle of a rotary engine: The rotary engine directly converts the combustion expansion force of combustible gas into driving torque. Compared with reciprocating engines, the rotary engine eliminates useless linear motion, resulting in a smaller size, lighter weight, and lower vibration and noise for the same power output, giving it significant advantages. Conventional engines are reciprocating engines, where pistons move back and forth in a straight line within the cylinders. To convert this linear motion into rotational motion, a crankshaft-slider mechanism is required. In contrast, the rotary engine uses a triangular rotor's rotational motion to control compression and exhaust, which differs significantly from the linear motion of traditional reciprocating piston engines.

Does an Engine Boiling Over Require an Overhaul?

An engine boiling over does not require an overhaul. When an engine boils over, a large amount of white steam will emerge from the engine cover, which is very easy to notice. At this point, you only need to immediately stop the vehicle, turn off the engine, and let it cool down naturally. As long as the operation is standardized, it is rare for an overhaul to be necessary. Causes: There are many reasons for a car boiling over. Apart from hot weather, overloaded air conditioning operation and faulty cooling components can also cause the car to boil over. Conducting a comprehensive inspection of the car's cooling system is the primary method to prevent boiling over. Check whether the cooling fan is working properly, whether the radiator is leaking, and whether there is a lack of coolant. If the radiator is leaking, it needs to be repaired or replaced promptly. If the radiator is low on coolant, it should be replenished in time. If the coolant becomes turbid or deteriorated, it needs to be replaced. Solution for a Boiling Over Car: The first thing to do when noticing the engine boiling over is to immediately pull over and stop the car. Boiling over means the engine is losing its cooling capacity, and the internal temperature of the engine will rise rapidly at this time. If the cooling is not sufficient immediately or the operation is not standardized enough, it can easily affect the strength of internal components such as pistons, piston rings, and connecting rods, causing them to weaken, deform, or even be damaged. In severe cases, it may lead to the engine being directly scrapped.
