LXH engine is an upgraded version of the LSY engine. 1. Purpose: The newly released LXH engine for the latest Cadillac XT6 was primarily designed to meet China's National 6B emission standards by adding a particulate filter, with the maximum power reduced to 169KW. Some models also incorporated a 48V hybrid system to improve fuel economy. 2. Additions: Besides the particulate filter in the exhaust system, the LXH engine also reduced cylinder working pressure to avoid side effects caused by exhaust blockage and high temperatures. 3. LSY: The LSY engine was first introduced in August 2018 on the Cadillac XT4 model. This engine is GM's all-new 2.0T variable cylinder turbocharged engine. Compared to the LTG engine, the LSY engine boasts higher technological sophistication and significantly optimized fuel efficiency. With the addition of cylinder deactivation technology, this engine can operate in three modes at different speeds: four-cylinder low-lift mode for daily driving and two-cylinder mode for high-speed cruising.

Is it necessary to remove formaldehyde from a new car?

It is very necessary. Here are the relevant details: Hazards: The main sources of formaldehyde in a new car come from the roof felt, seat covers, plastic parts of the dashboard, and other decorative materials. Benzene comes from adhesives. Among these, formaldehyde pollution is particularly severe and poses significant harm to human health. Removing formaldehyde: Remove the plastic packaging inside the car as soon as possible to allow harmful gases to dissipate quickly. Develop a habit of slightly opening the windows while driving to facilitate air circulation and carry away formaldehyde. Use activated charcoal or diatomite to adsorb formaldehyde. Note that activated charcoal tends to saturate easily and needs to be replaced after a period of use; otherwise, overloaded charcoal may release the adsorbed formaldehyde back. Comparatively, diatomite not only adsorbs but also decomposes the absorbed harmful substances. It does not require sun exposure and does not saturate, making it a better choice.

How often should the ATENZA transmission fluid be changed?

ATENZA transmission fluid should be changed every 20,000 to 40,000 kilometers. Transmission fluid is an oil product that keeps the gear system clean, lubricates to extend the service life of transmission components, and provides effective lubrication even at low temperatures. There are two types of transmission fluid: one is automatic transmission fluid, specifically for automatic transmissions; the other is manual transmission fluid, also called gear oil. Different vehicle models and different types of transmission fluid have different replacement cycles. Automatic transmission fluid should be changed every two years or approximately every 50,000 to 80,000 kilometers, while manual transmission fluid should be changed every three years or approximately every 100,000 kilometers.

What Causes Difficulty Starting a Diesel Vehicle?

Difficulty starting a diesel vehicle may be caused by prolonged parking. Here are relevant details about diesel vehicles: Precautions: Pay attention to excessively high engine coolant temperature. First, move the vehicle to a well-ventilated and shaded area. Then open the engine hood and wait for the coolant temperature to decrease. If immediate opening is necessary, use a large towel soaked in water to cover the coolant reservoir cap before attempting to slowly open it. When steam emerges, quickly move your hand away and wait until the steam completely dissipates before finally opening the cap to add coolant. Service Life: Mandatory scrapping occurs when the mileage reaches 600,000 kilometers, but the actual condition of the vehicle must also be considered. Every vehicle has its own predetermined scrapping timeline from the date of purchase, as specified by national transportation authorities through regulations that establish safety inspection requirements based on seating capacity and usage period.

Will You Be Caught by Cameras When Making an Illegal U-Turn on a Red Light?

When making an illegal U-turn on a red light, if the road is equipped with an electronic monitoring system, there is almost a 100% chance of being caught. Here are the relevant details: 1. No monitoring system: If you run a red light while making a U-turn at an intersection without an electronic monitoring system, you will not be photographed by traffic cameras. However, this scenario is very rare and usually occurs at traffic light intersections in small towns. Most traffic light intersections in urban areas are equipped with electronic monitoring. 2. Traffic regulations: Violations such as running a red light while making a U-turn, turning left, or going straight are all penalized as violations of the red light phase prohibition. The penalty is applied for crossing the stop line and continuing to drive. To deter drivers from deliberately running red lights, traffic police departments impose a penalty of 6 demerit points for such violations.
