Is It Necessary to Warm Up the Car Before Driving?

Reasons why warming up the car is necessary are as follows: 1. After the car has been parked for a long time, the engine oil flows back into the oil pan at the bottom of the engine. Therefore, when starting the engine after a long period of inactivity (such as overnight), the upper part of the engine is without oil and lacks lubrication. It takes about 30 seconds after starting for the oil pump to circulate the oil to the parts that need lubrication the most, such as the pistons, connecting rods, and crankshaft. 2. Before the engine reaches its operating temperature (approximately between 90-110 degrees Celsius), the fuel supply system cannot effectively vaporize the gasoline completely due to the low temperature (liquid gasoline vaporizes when it reaches its boiling point).

What does the China V emission standard logo look like?

The China V emission standard logo is only found in vehicle documentation, represented by the letter "V". Below is some information about the China V standard: 1. The China V standard, officially known as the National Fifth Stage Motor Vehicle Pollutant Emission Standard, is abbreviated as "China V Standard". 2. The emission control level of China V standard is equivalent to the European Euro 5 emission standard currently in implementation. Compared to China IV standard, the new standard reduces nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. 3. To further enhance vehicle exhaust purification system capability and reduce vehicle pollutant emissions, the sulfur content limit has been reduced from 50ppm in Stage IV to 10ppm, representing an 80% reduction.

What to Do When Your Car Won't Start?

When the battery is low on power, the starter cannot work, causing the vehicle to fail to start. In this case, the only solution is to jump-start the car or replace the battery. When the vehicle is in D gear, it cannot start. Simply reset the gear to P position to start the engine. If the engine temperature is too low, the car won't start. Turn the key to the power-on position, and the heating light on the dashboard will illuminate. Once the heating light goes off, you can start the car normally. If the spark plugs are clogged, the car won't start. In this situation, the only solution is to replace or clean the spark plugs. If it's not a battery issue, then the car needs to be towed to a repair shop for inspection.

What Brand is Giti Tire?

Giti Tire, also known as Giti Tire, is one of the world's leading tire manufacturers, offering a comprehensive range of high-quality tires that cater to various vehicle types, including sedans, racing cars, SUVs, off-road vehicles, trucks, buses, construction machinery, and agricultural machinery. Founded in Singapore, Giti Tire is an international tire manufacturing company headquartered in Shanghai, with seven factories located in five strategic cities across China. As one of the world's technologically advanced tire producers, Giti Tire provides a complete range of high-quality tires. The company adopts a multi-brand strategy to meet market demands with a comprehensive and superior product lineup, primarily exporting to North America and Europe, with products sold in over 100 countries and regions worldwide. Giti Tire is one of China's largest international tire manufacturers. Giti Tire offers numerous tire models, each with varying levels of wear resistance. The brand's tire lineup consists of four series: Giti Control Series, Giti Comfort Series, Giti SUV/Off-Road Series, and Giti All-Season Series. The Giti Control Series incorporates ISOM finite element carcass structure design derived from Giti's racing R&D technology, featuring high-strength polyester cord carcass and ultra-hard bead filler. This not only enhances tire safety but also ensures more precise handling. The robust shoulder blocks and transverse groove design minimize tread pattern deformation during cornering, providing stronger support for higher-speed turns. The Giti Comfort Series utilizes 3P technology and multi-pitch chaotic pattern arrangement to effectively reduce tread noise, improve comfort, and offer long mileage and fuel efficiency. The Giti SUV/Off-Road Series employs 'Durable Contact Patch' technology to enhance the tread's ground contact capability, along with a low rolling resistance and wear-resistant compound. This reduces rolling resistance while increasing tire durability. Additionally, the double-layer high-strength polyester carcass and high-modulus steel belt improve carcass uniformity, reducing road vibrations for a more comfortable ride. The Giti All-Season Series excels in wet and dry road performance, delivering consistent performance in both winter and summer conditions. For daily use of Giti tires, the following points should be noted: Regularly inspect the tire surface for cracks, deformations, or other defects. As tires wear, the tread grooves gradually become shallower. Worn-out treads lose their water drainage and anti-skid functions, significantly reducing vehicle performance. Small cracks can pose hidden dangers for blowouts at high speeds. Additionally, promptly remove stones lodged in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Keep vehicles away from or in contact with petroleum products, acids, or other materials that may deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool overheated tires. In hot weather or during high-speed driving, tires may overheat, increasing air pressure. In such cases, park to allow natural cooling. Never release air to reduce pressure or splash water to cool, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent and hard braking to prevent accelerated tread wear caused by dragging between the tire and the road surface.
