When will the ATSL undergo a model change?

The timing for the ATSL model change depends on when the ATS production is discontinued. With the discontinuation of the ATS, the domestically produced ATS-L model will also undergo a change. According to Cadillac's new vehicle plan before 2021, the current CTS and ATS models will be phased out. Below are the details about the ATS-L: 1. Body dimensions: The currently available (2017 model) Cadillac ATS-L was launched on December 22, 2016, with a body length of 4730mm, width of 1824mm, height of 1426mm, and a wheelbase of 2860mm. 2. Powertrain: It is equipped with a 2.0T SIDI direct-injection turbocharged engine, delivering a maximum power of 279 horsepower and a peak torque of 400 Nm, paired with an 8-speed automatic transmission.

What size should the bottom hole for M30 be drilled to?

m30 bottom hole size should be determined based on the pitch. Concept of bottom hole: The bottom hole generally refers to the diameter of the pre-drilled hole before tapping internal threads with a tap. It usually refers to the built-in circular hole of the workpiece, which is the bottom or top circular hole, hence called the bottom hole. However, the bottom hole is not necessarily drilled out; it can also be processed by other methods. Calculating the bottom hole size: Since the formula for the bottom hole is thread diameter minus pitch, given that the thread diameter is 30 mm and assuming the pitch is 1.5 mm, substituting into the formula gives the bottom hole size as 30 - 1.5 = 28.5 mm.

Does PEA concentrate harm the car?

PEA concentrate does not harm the car. Functions of PEA concentrate: PEA concentrate refers to undiluted 100% polyetheramine with a molecular weight of 1000, which can be stored for 3 years when properly sealed. It is mainly used to remove carbon deposits in cars. Precautions for using PEA: This type of cleaning fuel additive should be used periodically, typically added once every few thousand kilometers. Continuous use is not recommended as it may cause engine shaking, increased fuel consumption, and other issues. Due to the relatively high viscosity of polyetheramine FL1000, patience is required when pouring it directly into the fuel tank. It is advisable to use several small empty bottles to transfer the concentrate from the large bottle into smaller bottles before adding it to the fuel tank.

What is the difference in fuel consumption between China V and China VI?

China VI gasoline contains 10% more ethanol in its additives, which is equivalent to 10% less gasoline content. Under the premise of maintaining the same vehicle configuration, it can be said that China VI has higher fuel consumption, but China VI gasoline is also relatively cheaper. The following is a related introduction: 1. Emission standards: As global environmental pollution problems become increasingly severe, countries around the world are implementing stricter emission standards, which is greatly beneficial for protecting the Earth's environment. 2. Exhaust treatment: Under strict emission standards, automakers will actively develop new technologies to reduce engine exhaust emissions.

What Does Car Tire Size Represent?

Tire size refers to the dimensions of the tire. Generally, the size of tires used on cars is printed on the sidewall of the tire. Different types of vehicles use different tire sizes. Meaning of tire size markings: Taking a tire model like 250/60R1589H as an example, in this set of parameters, different letters represent different meanings. Among them, 250 represents the width of the tire, which is essentially the part of the tire that comes into contact with the ground. The wider the tire used on a car, the larger the contact area with the ground, resulting in better stability performance during actual driving. 60 represents the aspect ratio of the tire, which is the ratio of the height from the rim to the tread to the maximum width of the tire's cross-section. This value is usually expressed as a percentage. R stands for radial tire. Generally, household cars use radial tires, which are widely used in family vehicles. 15 represents the size of the tire, specifically the inner diameter. 89 indicates the maximum load capacity of the tire, which should not be exceeded during vehicle use. H represents the maximum speed rating of the tire, which should not be exceeded during driving. Tire maintenance methods are as follows: Perform wheel alignment and tire rotation regularly. For vehicles driven under normal road conditions, it is recommended to perform wheel alignment and tire rotation every 10,000 kilometers. Errors in wheel alignment angles and prolonged lack of tire rotation may lead to steering deviation and abnormal tread wear. Regularly check tire pressure. Tire maintenance also includes periodic pressure checks. Tires with pressure exceeding the specified limit will significantly reduce their service life, while those with pressure below the specified limit may cause poor braking performance, steering difficulties, or heavy steering, and also shorten the tire's lifespan.
