2021 Cars Without Particulate Filters: Audi 2.0T high-power engine does not have one; Hongqi 2.0T does not have one; Toyota: None of its models are equipped with particulate filters; Honda: Lingpai Hybrid, CR-V Hybrid, Accord Hybrid, etc.; Mazda: Axela, CX-30, CX-5, etc.; BYD: Qin PLUS DM-i, Song PLUS DM-i. Function of Particulate Filters: Particulate filters can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. To check if a vehicle has a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, you can carefully review the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look at the exhaust pipe behind the three-way catalytic converter to see if there is a cylindrical section. If there is, that is the particulate filter.

What are the rules for highway toll exemption?

Highway toll exemption rules are: 1. The toll-free period covers four national statutory holidays: Spring Festival, Qingming Festival, Labor Day, and National Day. The free period starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day of the holiday; 2. The vehicles eligible for free passage are passenger vehicles with 7 seats or fewer (including 7 seats) traveling on toll roads, including motorcycles permitted on ordinary toll roads; 3. The toll roads eligible for free passage are those that comply with the "Highway Law of the People's Republic of China" and the "Regulations on the Administration of Toll Roads," and have been legally approved as toll roads (including toll bridges and tunnels).

Can You Brake with the Left Foot in an Automatic Transmission Car?

Automatic transmission cars cannot be braked with the left foot. In an automatic transmission car, the brake and accelerator are controlled by the right foot. The reasons why the left foot should not be used for braking are: 1. The right foot controlling both the accelerator and brake ensures that only one pedal can be pressed at a time. The right foot must leave the accelerator pedal to press the brake, preventing the simultaneous pressing of both pedals; 2. Using the left foot for braking only occurs in two scenarios: either the left foot is constantly placed on the brake pedal, or the right foot leaves the accelerator and the left foot presses the brake when braking is needed; 3. In manual transmission cars, which have an additional clutch pedal, attempting to brake with the left foot might accidentally press the clutch instead, leading to a missed braking opportunity.

What's the difference between 1.5L and 1.5T?

The differences between 1.5L and 1.5T are: 1. Different engine types: The 1.5L is a naturally aspirated engine; the 1.5T is a turbocharged engine. 2. Different power outputs: For cars with the same displacement, the power of a turbocharged engine is 1.3 times that of a regular naturally aspirated engine. 3. Different working principles: The air intake of a 1.5L naturally aspirated engine is mainly driven by the downward movement of the piston; in a 1.5T turbocharged engine, the exhaust gases produced during engine operation drive the turbine, which increases the intake air volume, allowing more complete combustion in the engine cylinders, thereby reducing fuel consumption and increasing vehicle horsepower.

What is the Mnemonic for Judging Distance Through Rearview Mirrors?

The mnemonic for judging distance through rearview mirrors is: 1. The smaller the rear vehicle appears, the safer it is; 2. When the rear vehicle occupies one-third of the mirror, the distance is about 10 meters; 3. When the rear vehicle occupies half of the mirror, the distance is about 7 meters, suitable for turning; 4. When the rear vehicle fills the entire mirror, the distance is about 3 meters, not suitable for turning. When you see a vehicle approaching from the right lane in the rearview mirror, observe its position in the mirror while considering its speed. If only part of the rear vehicle's front is visible in the mirror, it indicates a very close distance, and you should delay changing lanes to avoid a rear-end collision. If the entire front of the rear vehicle is within the mirror's range, it means the distance is at least 5-6 meters, and you can accelerate to change lanes to the right.

Which has a longer lifespan, a three-cylinder or four-cylinder engine?

Four-cylinder engines have a longer lifespan. Due to the inherent imbalance in torque distribution of three-cylinder engines, their crankshafts and connecting rod piston components cannot achieve true moment equilibrium. This leads to accelerated wear at the crankshaft bearing locations, resulting in a theoretically shorter service life compared to four-cylinder engines. A three-cylinder engine consists of three cylinders arranged within a single engine block sharing one crankshaft for power output, primarily converting chemical energy into mechanical energy. A four-cylinder engine is a machine that transforms one form of energy into another more useful form, with its main components including the cylinder block, crankcase, cylinder head, and cylinder gasket.

How to Remove Fog from Car Windows in Winter?

Methods to remove fog from car windows in winter: 1. Most vehicles are equipped with a defogging function; simply activate the window defogger to quickly blow away moisture. 2. Use a specialized glass defogging spray by applying it to the inside of the windshield to eliminate fog. 3. Dish soap can also be cleverly used to prevent fogging—dilute the soap with water and wipe the windows. 4. Window fogging is largely related to the significant temperature difference between the inside and outside of the car. Therefore, when fog appears, you can open the windows to increase air circulation, utilizing this method to reduce the temperature difference and achieve a defogging effect.
