Differences Between EV, HEV, and PHEV are introduced as follows: 1. Different driving methods. EV is a pure electric vehicle, which relies entirely on electric energy for propulsion, with driving completely dependent on electric energy; HEV is a hybrid energy vehicle, adding a set of motor equipment on the basis of the original car equipment; PHEV is a plug-in hybrid electric vehicle, also adding a set of motor equipment to the gasoline car, but the battery of PHEV is larger, which can support longer pure electric driving. 2. Different advantages and disadvantages. EV cars do not need to pay vehicle purchase tax, and can also have a unique new energy license plate in China, but pure electric models generally have insufficient endurance; The advantage of HEV is that the daily fuel consumption is relatively small, and the pollution emitted is also relatively small. The disadvantage is that it cannot drive in pure electric mode for a long time, and cannot enjoy the national subsidy policy for new energy; The advantage of PHEV is that it can be driven as an electric vehicle or a gasoline vehicle, and the conversion mode is more thorough. As long as the cruising range can exceed 50 kilometers, it can enjoy the new energy subsidy policy given by the state, but the large equipment will also make the body heavier, so the car may consume more fuel after running out of electricity.

Is Highway Toll-Free During Mid-Autumn Festival?

During the Mid-Autumn Festival holiday, highways will charge tolls as usual without any exemption. Below are the specific policies for toll-free highway passage: 1. Statutory Holidays: According to the "Implementation Plan for Exempting Toll Fees for Small Passenger Vehicles During Major Holidays," the toll-free periods apply to four national statutory holidays—Spring Festival, Qingming Festival, Labor Day, and National Day—as well as the consecutive holidays determined by the State Council in the same year. 2. Toll-Free Period: The toll-free period starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day (for ordinary roads, the toll-free period is based on the time the vehicle passes through the toll booth lane, while for highways, it is based on the time the vehicle exits the toll booth lane).

How to Check the Manufacturing Date of a Car Seat Belt?

There is a label attached at the very bottom of the car seat belt, which displays the manufacturing date of the seat belt. Below is a detailed introduction on how to identify the manufacturing date of a car seat belt: 1. Chinese Seat Belts: The date is directly printed on the label. 2. English Seat Belts: The format is generally more complex. The date follows the "MFDDATE" label. If "MFDDATE" is followed by a combination of letters and numbers, it indicates the use of a 17-digit coding rule, which is the Vehicle Identification Number (VIN). The tenth digit of the VIN is related to the date, following a 30-year cycle.

What Impact Does a Faulty Oil Cooler Have on the Engine?

The impact of a damaged oil cooler on the engine is as follows: 1. Engine oil mixing with water: The internal engine oil pipeline of the cooler is connected to the coolant pipeline, leading to water entering the engine oil, causing emulsification of the engine oil, and subsequently damaging the engine. 2. Oil leakage issues: Other common faults include blockage of the engine oil passage, leakage at the engine oil passage interface, blockage of the coolant pipeline, and leakage at the coolant pipeline interface. The functions of the engine oil cooler are as follows: 1. Cooling effect: If the engine oil temperature exceeds the normal value, it will cause the engine oil to become too thin, reducing the lubrication effect. Therefore, when the engine is hot, the coolant flowing through the engine oil heat exchanger is responsible for absorbing the heat from the engine oil, maintaining the average temperature of the engine oil in the lubrication system not exceeding the upper limit (generally 90°C). 2. Heating effect: During cold starts, the engine oil temperature is low and its fluidity is poor, which increases the rotational resistance of various engine components. Therefore, it is necessary to raise the engine oil temperature as quickly as possible. As the engine runs, the temperature gradually increases, and the coolant also heats up accordingly. At this time, the coolant, which is at a higher temperature than the engine oil, will heat the engine oil at the engine oil heat exchanger.

How often should Castrol EDGE oil be changed?

Under normal circumstances, Castrol EDGE should be changed once a year or every 10,000 kilometers, as it is a fully synthetic engine oil. For more details, please see below: 1. Oil change frequency: Normally, fully synthetic oil should be changed every 10,000 kilometers or about one year, semi-synthetic oil every 7,500 kilometers or about nine months, and mineral oil every 5,000 kilometers or about six months. Time or mileage, whichever comes first. 2. Introduction to Castrol EDGE: The Castrol EDGE series is the top-tier fully synthetic engine oil from Castrol, all of which are SN-grade, on par with Mobil 1 and Shell Helix Ultra. Castrol EDGE comes in four viscosities to meet different driving condition requirements. The four viscosities are: 0W-40, 5W-40, 5W-30, and 10W-60.

What are the side effects of installing a power window kit?

The side effects of installing a power window kit include water leakage or damage to the battery. Below are specific details about the side effects of installing a power window kit: 1. Poor sealing: Installing a power window kit may lead to water leakage. Since the power window kit is an aftermarket addition, installation requires disassembly. Poor installation or issues with the kit itself can result in inadequate sealing, potentially causing water leakage. 2. Anti-pinch function: Prevents accidental injury to passengers during the automatic window closing process. 3. Battery damage: Aftermarket power window kits may not match the car's electrical current, which could lead to battery damage during use. It is recommended that owners install the kit properly and choose a reliable, high-quality power window kit.
