What is the model code of the Blue Whale engine?

Blue Whale 1.4T engine model is JL473ZQ3. Currently, the Blue Whale engine is only available in a 2.0L displacement, applied in Changan's premium SUV-CS95, so the Blue Whale engine technology has not yet been popularized in 1.0T or 1.5T engines. The following is an introduction to the engine model content: 1. Front part: Includes product series code, generation symbol, and local or enterprise code, with manufacturers selecting corresponding letters as needed, but must be approved and filed by the industry standard standardization unit. 2. Middle part: Consists of cylinder number symbol, cylinder arrangement symbol, stroke symbol, and cylinder diameter symbol. 3. Rear part: Composed of structural feature symbol and usage feature symbol. 4. Tail part: Distinguishing symbol. When differentiation is needed for the same series due to improvements, manufacturers choose appropriate symbols, and the rear and tail parts can be separated by "-".

Which button is for the seat ventilation in the Passat?

The seat ventilation button for the Volkswagen Passat is located in the middle of the center console, on the far left. Pressing it activates the ventilation mode, and you can also adjust the seat temperature. Here is some additional information about the Passat: 1. Passat: The Passat sedan surpasses the standard design of mid-range cars in terms of power performance, overall design, safety concept, driving comfort, durability, and longevity. Engineers at Volkswagen Germany have perfectly combined automotive design and technology to create the Passat sedan, which offers superior value. 2. Air Conditioning: The seat ventilation system features a unique air circulation system that continuously delivers fresh air through small holes in the seat cushion and backrest, preventing sweat buildup on the hips and back. This provides a comfortable riding environment and effectively improves air circulation between the body and the seat surface, ensuring a dry and comfortable contact area even during long rides.

What is the size of a 14*2.125 tire in inches?

14*2.125 tire is 14 inches. Here is the relevant introduction about tires: 1. Introduction: Automobile tires are one of the important components of a vehicle, directly contacting the road surface. Together with the car suspension, they help mitigate the impacts encountered during driving, ensuring good ride comfort and smooth driving performance. They also ensure excellent adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capabilities, and bear the weight of the car. The significant role tires play in automobiles has gained increasing attention. 2. Size classification Full-size spare tire: The specifications of a full-size spare tire are exactly the same as the other four tires on the vehicle, allowing it to replace any tire that is temporarily or permanently unusable. Compact spare tire (non-full-size spare tire): This type of spare tire has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary replacement. It should only be used on non-driving wheels, and the maximum speed should not exceed 80km/h.

What brand are the original brake pads for Volvo?

Volvo S90 brake pads are from the German brand Jurid. Here is some related information: 1. Brake Pads: Brake pads, also known as brake linings, are the most critical safety components in a car's braking system. The effectiveness of all braking depends decisively on the brake pads. 2. Material: Brake pads (brake-lining) are generally composed of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored using an SMT-4 oven temperature tracker to ensure quality by detecting the temperature distribution during the coating process. The heat insulation layer is made of non-heat-conductive materials to provide thermal insulation. 3. Friction Block: The friction block consists of friction materials and adhesives. When braking, it is pressed against the brake disc or drum to create friction, thereby achieving the purpose of slowing down or stopping the vehicle. Due to the friction, the friction block gradually wears out. Generally, the lower the cost of the brake pads, the faster they wear out.

How to Find the 30cm Point for Pulling Over?

Align the driver with the center of the road, then slightly adjust to the right. Position the front one-third of the car's hood on the right lane edge line and straighten the vehicle. Slowly brake when the car is approximately 30cm away from the edge line to bring the vehicle to a stop. Relevant details are as follows: 1. Wiper Method: Observe the wiper. When the gap in the wiper aligns with the edge line while moving forward, the car is approximately 30cm from the edge line. Alternatively, look at the car's hood reinforcement line—the raised line on the right side of the hood. When this line aligns with the edge line while moving forward, the distance is also roughly 30cm. 2. Parking Restrictions: Remember that when pulling over, parking is prohibited in the following areas: intersections, railway crossings, curves, narrow roads, narrow bridges, steep slopes, tunnels, and within 20 meters of these locations; sections with pedestrian guardrails (hedges), crosswalks, construction zones, or opposite obstacles; bus stops, tram stops, emergency stations, gas stations, fire hydrants, or within 30 meters in front of fire stations.
