In winter, the normal tire pressure for cars is between 2.2 and 2.4 bar. Excessive tire pressure in winter reduces the friction between the car tires and the road surface, affecting driving safety. Slightly lowering the tire pressure by 0.1 bar below the standard can increase the tire's grip on the road. If the tire pressure is too low, it can increase the car's fuel consumption, cause damage to the tires, and easily lead to tire blowouts. The standard tire pressure for each car can be checked at the fuel filler location. The first row in the tire pressure chart indicates the standard tire pressure, which is generally 2.3 bar for most passenger cars. The tire pressure value refers to the cold tire pressure, measured after the car has been parked for at least 3 hours or if the tires have not been driven more than 2 kilometers. If tire pressure can only be measured when the tires are hot, subtract approximately 0.3 bar from the measured value. Strictly speaking, tire pressure refers to the air pressure inside the tires. In terms of car maintenance, the engine is the heart of the car, and damage to the engine can lead to the end of the car's life. Tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the car's performance and power.

How often is the vehicle license reviewed?

Different types of motor vehicle licenses have different review periods. For commercial passenger vehicles, the license is reviewed annually for the first five years, and every six months thereafter. For large and medium-sized trucks, the license is reviewed annually within the first ten years, and every six months after ten years. Small non-commercial cars and motorcycles are exempt from on-site annual reviews for the first six years, and then reviewed biennially from six to ten years. Vehicle license annual review process: Required documents: Original and copy of the vehicle license, proof of vehicle and vessel tax, original insurance card, original ID card. Check online for any traffic violations and ensure they have been resolved. Self-service procedure: Obtain the annual review form from the driving association and get it stamped; take the form to the local traffic police team for another stamp. Then, take the form to the vehicle inspection line entrance for signing, enter the inspection line, and undergo vehicle checks including front and rear brakes, parking brake, emissions, lights, and horn sound. After inspection, proceed to the engine model number check. Collect the inspection results form in the office and pay fees for any failed items, re-inspection, and model number check. Finally, with the annual review form, inspection results form, and vehicle license, collect the vehicle inspection certificate and have the license printed with the new validity period. Submit the annual review form and inspection results form to the local vehicle management office for archiving, and replace the old road and bridge IC card with a new one.

What is the wading depth of the Jeep Compass?

The maximum wading depth of the Jeep Compass is 480mm. The wading depth of the Jeep Compass is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the Jeep Compass is below the water level while wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth must not exceed the height of the engine's air intake. Alternatively, the height of the engine's air intake (and thus the maximum wading depth) can be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in water, which could cause severe damage due to water ingress; Assess the underwater road conditions based on the passage of preceding vehicles and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration; On waterlogged roads, use warning water level markers, trees, or the wheels and doors of other vehicles as reference points to estimate the water depth before deciding whether to proceed; Know your vehicle's safe wading depth. If the water depth exceeds half the tire height or the engine's air intake, avoid entering the water and choose an alternative route.

Should the 2021 Sagitar use 92 or 95 octane gasoline?

According to the official vehicle manual recommendation, the 2021 Sagitar should use 95 octane gasoline. For the 2021 Sagitar, besides checking the appropriate gasoline grade in the vehicle manual, you can also find it on the fuel tank cap, which will also indicate the recommended grade. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of some new technologies, the compression ratio alone cannot determine the gasoline grade to use. High compression ratio engines can also be tuned to use lower octane gasoline. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number, and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the 2021 Sagitar occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, and the actual feedback experience is reduced performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases and it may ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance makes the engine run very unstably. If the knocking is imperceptible, it only increases noise without significant damage to the engine. However, if there is noticeable knocking, it indicates severe engine conditions. The vibration not only affects driving stability but can also cause abnormal wear on the pistons and cylinders, and in severe cases, cylinder scoring.
