What are the new regulations for the annual review of school bus driver's licenses?

School bus drivers should go to the traffic management office for review within thirty days after the end of each scoring cycle. Here is an introduction about school buses: Introduction to school buses: A school bus refers to a passenger vehicle with more than seven seats that has obtained a usage permit in accordance with the "School Bus Safety Management Regulations" and is used to transport students receiving compulsory education to and from school. Related safeguards for school buses: To ensure the safety of school bus passage and parking, the draft also grants three priorities to school buses: when a school bus is transporting students, traffic police should direct and guide the school bus to have priority passage; school buses can drive on bus lanes and other sections of roads where social vehicles are prohibited but buses are allowed; when a school bus needs to stop on the road to pick up or drop off students, vehicles behind should stop and wait, and overtaking is prohibited.

Does a plug-in hybrid consume more fuel if not charged?

According to the design, plug-in hybrid vehicles are most fuel-efficient when operating in pure electric drive mode. If they are not charged for a long time, they operate purely on fuel mode, just like conventional vehicles. Reasons: Even when not charged, plug-in hybrids still maintain about 15% of the initial battery charge. During startup and low-to-medium speed driving, the electric motor still intervenes to avoid the inefficient operating conditions of the fuel engine. In hybrid mode, the electric motor also provides additional boost during sudden acceleration. Plug-in Hybrid Electric Vehicle (PHEV): A Plug-in Hybrid Electric Vehicle (PHEV) is a type of new energy vehicle that bridges the gap between pure electric vehicles and conventional fuel vehicles. It has the engine, transmission, drivetrain, fuel system, and fuel tank of a traditional car, as well as the battery, electric motor, control circuit, and a charging port of a pure electric vehicle, with a relatively large battery capacity. Combining the advantages of both pure electric vehicles (EVs) and hybrid electric vehicles (HEVs), PHEVs can achieve pure electric, zero-emission driving and also extend the vehicle's range through hybrid mode.

What are the models of diesel cars available?

Diesel cars available in the market include the Audi A6L diesel version, BMW 3 Series diesel version, etc. Here is some related information about diesel: Concept: Diesel is a light petroleum product, a complex mixture of hydrocarbons (carbon atoms number about 10-22), used as fuel for diesel engines. Properties: Diesel has a boiling point range and viscosity between kerosene and lubricating oil. It is flammable, volatile, insoluble in water, and soluble in alcohols and other organic solvents. It is a complex mixture with two boiling point ranges: 180°C-370°C and 350°C-410°C. Uses: Diesel is mainly used as power for tractors, large vehicles, diesel locomotives, construction machinery, excavators, loaders, fishing boats, diesel generator sets, and agricultural machinery. It serves as fuel for diesel cars, tractors, and other diesel engines.

Is Engine Oil Really Thin?

If it is thin, it is difficult to determine whether it is fake oil. Here is an introduction to engine oil knowledge: Introduction: Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the "blood" of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Additives are a crucial part of the lubricant. Requirements: As a type of machinery, engines share common requirements for lubricants with general machinery, such as appropriate viscosity, oxidation resistance, wear resistance, corrosion protection, and viscosity-temperature performance. However, engines are also unique machinery, and their requirements for lubricants have special aspects.

What is the fault when the catalytic efficiency of the car catalyst is low?

Low catalytic efficiency of the car catalyst may be caused by the use of leaded gasoline or a malfunctioning oxygen sensor in the car leading to excessively low efficiency. Below is an introduction to the related content of the three-way catalytic converter: Three-way catalytic converter: The three-way catalytic converter is the most important external purification device installed in the car's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Purifying agent: When high-temperature car exhaust passes through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of the three gases CO, HC, and NOx, promoting certain oxidation-reduction chemical reactions. Among them, CO oxidizes at high temperatures into colorless, non-toxic carbon dioxide gas; HC compounds oxidize at high temperatures into water (H2O) and carbon dioxide; NOx is reduced into nitrogen and oxygen. The three harmful gases are transformed into harmless gases, thereby purifying the car's exhaust.

Can the Mechatronic Unit Be Repaired If It's Broken?

No. The transmission mechatronic unit is highly susceptible to high temperatures. Here is some relevant information about the transmission mechatronic unit: Function: The transmission mechatronic unit is the control center of the transmission. Its input circuit receives signals from sensors and other devices, then filters, processes, and amplifies these signals before converting them into electrical signals to drive the controlled solenoid valves. The mechatronic unit also manages the vehicle's shifting logic, ensuring the transmission better matches the engine's operating state, thereby enhancing the controllability of the vehicle's power, acceleration, and smoothness. Relationship with Temperature: The damage to the mechatronic unit is largely related to high transmission temperatures. During aggressive driving, the temperature inside the clutch plates or torque converter can become extremely high. This heat can cause the electronic control unit to malfunction, and typically, the only solution is to replace the unit with a new one.
