How low should tire pressure be in hot weather?

In summer, the normal tire pressure ranges between 2.3-2.5 bar, but the specific value should be determined based on the manufacturer's recommendation. Due to the principle of thermal expansion and contraction, summer tire pressure should be maintained at the lower limit of the standard pressure. If the car is parked in direct sunlight during summer, the tire pressure should be reduced by an additional 0.1 bar from the standard pressure to prevent tire blowouts caused by high temperatures. Other factors affecting tire pressure include: 1. Road conditions: On rough roads, the tire pressure can be appropriately reduced by 0.2 bar from the standard pressure. For long-distance highway driving, the tire pressure can be appropriately increased by 0.2 bar from the lower limit of the standard pressure. 2. Measurement environment: The tire pressure of a hot tire differs from that of a cold tire, with a difference of about 0.3 bar. The manufacturer's recommended tire pressure generally refers to the measurement under cold tire conditions. 3. Vehicle load: For half-load conditions, use the lower limit of the standard tire pressure; for full-load conditions, use the upper limit of the standard tire pressure.

Do Aftermarket Three-Way Catalytic Converters Contain Metal?

Generally, qualified aftermarket three-way catalytic converters contain metal content. These include precious metals such as platinum (Pt), rhodium (Rh), and palladium (Pd). Below is some additional information: 1. Three-Way Catalytic Converter: A three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases like CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. Precautions: High-quality aftermarket three-way catalytic converters are generally fine, but the automotive parts market is mixed with varying quality. It is recommended to replace the catalytic converter with an original equipment manufacturer (OEM) part at a 4S shop. Typically, OEM catalytic converters offer better compatibility than aftermarket ones. Using a low-quality catalytic converter can not only lead to excessive emissions but also increase exhaust backpressure, negatively affecting engine performance.

Why is it acceptable to drive at 60 km/h on an elevated ramp with a speed limit of 40 km/h?

Because when the speed limit is below 60 km/h, exceeding it by less than 50% does not incur penalties, hence driving at 60 km/h on an elevated ramp with a speed limit of 40 km/h is acceptable. Below are specific details about motor vehicle speed limits: 1. Introduction: Speed limits are imposed on certain vehicles for safety considerations, restricting their maximum speed. For example, high-end sedans and sports cars from German brands like Mercedes-Benz, BMW, and Audi have their top speeds limited to 250 km/h. 2. Basis: The establishment of speed limit standards is not solely based on the number of lanes but takes into account factors such as road classification, traffic volume, road width, and the presence of median barriers. For instance, the speed limit for primary highways can be set between 60-100 km/h depending on specific conditions, while secondary roads may have limits of 40-80 km/h. Therefore, setting a speed limit of 60 km/h is backed by policy rationale.

Should the turn signal be used for hill start and stop?

Yes, the left turn signal should be used. The turn signal is not for your own indication, but to inform other vehicles or pedestrians. Hill start and stop is an assessment point in the driver's test, which includes two test items: stopping at a designated point on an uphill road and starting on a slope. It is one of the five mandatory test items. The penalty standards for hill start and stop are as follows: 1. The front bumper of the car is not aligned with the pole line: If the front bumper of the car is not aligned with the pole line after stopping, and the deviation exceeds 50cm, it is a fail. If the deviation does not exceed 50cm, 10 points will be deducted. 2. Starting time exceeds 30 seconds: If the starting time exceeds 30 seconds, it is a fail. 3. Wheels pressing the road edge line: If the wheels press the road edge line while driving, it is a fail. 4. Vehicle rollback distance: If the vehicle rolls back more than 30cm during start, it is a fail. If the rollback is more than 10cm but less than 30cm, 5 points will be deducted per occurrence. 5. Distance between the vehicle body and the road edge line: If the distance between the vehicle body and the road edge line exceeds 50cm after stopping, it is a fail. If the distance exceeds 30cm but does not exceed 50cm, 10 points will be deducted per occurrence. 6. Parking brake not tightened: If the parking brake is not tightened after stopping, 10 points will be deducted per occurrence.

Is it mandatory to install electronic license plates in Chongqing?

Chongqing electronic license plates must be installed. An electronic license plate tag is mounted on motor vehicles, using this RFID electronic license plate as the carrier of vehicle information. When passing through road sections equipped with authorized RFID readers, the data on each vehicle's electronic license plate is collected or written to achieve various comprehensive traffic management purposes. Electronic license plates are an application based on the segmentation, extension, and enhancement of passive radio frequency identification (RFID) technology in the Internet of Things. This entirely new technology can break through the bottlenecks of traditional traffic information collection methods, enabling classified and precise collection of vehicle traffic information, and ensuring the accuracy of the information source for traffic control systems.

What is the correct method for running-in a motorcycle?

Motorcycle running-in period correct method is to change to higher quality engine oil according to mileage, keep speed below 60km/h during running-in, and avoid continuous riding exceeding 30km. The running-in period generally refers to the process where mechanical components initially contact, rub, and mesh during operation. Motorcycles are gasoline-engine powered two or three-wheeled vehicles steered by handlebars, featuring lightweight maneuverability and rapid movement, widely used for patrols, passenger/cargo transport, and as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, sport bikes, off-road motorcycles, cruisers, and tourers. A motorcycle consists of five major components: engine, transmission system, running gear, braking system, and electrical instrumentation.
