Is Automatic Transmission the Same as Continuously Variable Transmission?

What Does Used Car Preparation Involve?

Used car preparation requires replacing engine oil, brake fluid, transmission fluid, and coolant. Below are the details of used car preparation: 1. Engine oil replacement (including oil filter): Engine oil is the most common item encountered during car maintenance. There is actually a lot to learn about choosing engine oil. Firstly, engine oils are categorized by quality grade into mineral oil, semi-synthetic oil, and fully synthetic oil. The biggest differences between them lie in lubrication effectiveness and oxidation resistance duration. 2. Brake fluid: Brake fluid is a crucial part of preparation, as it relates to safety. However, replacement isn't always necessary—it depends on the condition of the brake fluid. The main factor causing brake fluid failure is its water content. Auto repair shops have detection pens to measure water content in brake fluid. If the water content exceeds 4%, replacement is needed. 3. Transmission fluid: Replacement intervals depend on the type of transmission. For manual transmissions, fluid typically needs replacement every 100,000 kilometers. For automatic transmissions, it's around 60,000 kilometers. Additionally, different transmissions require different types of fluid. When selecting transmission fluid, opt for reputable brands with good reviews. 4. Coolant: Replacement isn't always urgent, but prolonged neglect can severely damage the water pump, thermostat, and water channels. Issues like overheating and high engine temperatures are often caused by these factors. Therefore, to protect the car's cooling system, coolant should be replaced regularly.

What is the battery model of the Refine S3?

The battery model of the Refine S3 is 55D23L 12V, with a battery capacity of 60Ah and a voltage of 12V. Below is more information about car batteries: 1. A car battery, also known as a storage battery, refers to a lead-acid battery. It is primarily made of lead and its oxides, with sulfuric acid solution as the electrolyte. It is a type of battery that works by converting chemical energy into electrical energy. 2. The normal service life ranges from 1 to 8 years, depending largely on the condition of the vehicle. Under normal circumstances where the vehicle's alternator charges properly and there are no electrical leaks or grounding issues, the battery can generally last for more than 3 years. If you notice that the battery is not charging properly, the starter is weak, or the headlights are significantly dimmer, the battery should be removed and charged with a charger for 12-24 hours.

Why Does Engine Oil Deteriorate?

Engine oil deterioration occurs due to the following reasons: 1. Water contamination in the oil: Experiments show that when the water content in the oil exceeds 0.1%, the added antioxidants and dispersants in the oil become ineffective, accelerating the oxidation process of the oil. When the water content reaches 1% or more, the lubricating properties of the oil deteriorate, viscosity decreases, leading to premature oil degradation and rusting of components in mild cases, and in severe cases, causing serious mechanical failures such as engine seizure or bearing damage. 2. Cylinder wear or piston ring damage: This allows fuel to enter the crankcase, reducing the oil's viscosity.

How to Replace the Battery in a Mazda Car Key?

Mazda car keys require battery replacement. Below is relevant information regarding the battery: Battery Lifespan: The key battery typically lasts about two years under normal usage. When the key battery is low, the dashboard will display a warning: "Key Battery Low." In such cases, replace the battery immediately. Factors Affecting Remote Battery Lifespan: A common issue is leaving the key near a phone's wireless charging area for extended periods, which can impact the key battery's lifespan. If your key runs out of power, don’t panic. The standard procedure is to use the mechanical key to manually unlock the car door by turning it.

What to Do When a Car Engine Won't Start Due to Dead Battery?

Solutions for a car engine that won't start due to a dead battery are as follows: 1. Jump-start using another car's battery: Pay attention to the order of connecting the cables; connect the positive terminal of the rescue car to the positive terminal of the faulty car, and the negative terminal of the rescue car to the engine ground. The order of disconnection is the opposite. 2. For manual transmission models, you can use the push-start method: Have someone sit in the driver's seat, turn on the ignition, press the clutch pedal, shift into second gear, and then have others push the car. When the speed reaches above 10 km/h, the driver quickly releases the clutch pedal, allowing the car to drag the engine to rotate, and the engine will start.

What Does Mercedes-Benz 63 Actually Mean?

Mercedes-Benz 63 initially referred to a 6.3-liter displacement. Here are the reasons: When the Mercedes-Benz 63 was first introduced, it featured a naturally aspirated V8 engine with a 6.3-liter displacement. Later, due to European restrictions on large-displacement engines, it was replaced with a 5.5T turbocharged engine. Despite the change, models like the C63, CL63, and ML63 retained their original names. Currently, it uses a 5T turbocharged engine, but Mercedes-Benz continues to use the 63 designation due to its established market recognition. Here is a brief introduction to the Mercedes-Benz 63: 1. In terms of body dimensions, the car measures 4769*1855*1938mm in length, width, and height, with a wheelbase of 2850mm. 2. In terms of power, the G63 is equipped with a 4.0L V8 twin-turbocharged engine, delivering a maximum power of 430kW and a maximum torque of 850 Nm, paired with a 9-speed automatic transmission.
