The 2011 Nissan Tiida complies with the China IV emission standard. The China IV emission standard is the fourth phase of the national standard for motor vehicle pollutant emissions. The main pollutants emitted by vehicles include HC, NOx, CO, PM, etc. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard controls and reduces vehicle emissions to below specified levels. Relevant information about the China IV standard is as follows: 1. The China III and China IV standards are based on the Euro 3 and Euro 4 vehicle emission standards. Compared to China II, China III further reduces the limits for pollutant emissions. The exhaust pollutant emission limits under China III are 30% lower than those under China II, while China IV will further reduce them by 60%. 2. According to the plan, Beijing implemented the 'National Fourth Phase Motor Vehicle Pollutant Emission Standard' (hereinafter referred to as the 'China IV emission standard') for all newly added motor vehicles in 2013. Gasoline meeting the China IV standard began to be supplied citywide starting from January 1, 2008.

Let's talk about the 2011 Nissan Tiida. Its emission standard was mainly China IV, as China IV had just come into effect around that time, and many new cars were manufactured to meet this requirement. Specifically, the emission calibration involved stricter limits on particulate matter and nitrogen oxides compared to the older China III standard, which helped reduce air pollution. However, after purchasing the car, it's best to check the Vehicle Conformity Certificate or the environmental label to confirm, as some early batches might have mixed China III products, especially for Tiidas bought in the first half of 2011. Nowadays, China IV vehicles might face restrictions in cities with traffic control policies like Beijing. It's recommended that owners regularly maintain the exhaust system to keep emissions compliant. The car is also fuel-efficient and drives smoothly overall, so not upgrading isn't a big issue, but in the long run, it's still worth considering switching to a more environmentally friendly model.

Is the fuel from mobile refueling vehicles the same as that from gas stations?

The fuel quality from external gas stations is basically the same as that from regular gas stations, but private gas stations purchase their fuel directly from petroleum companies affiliated with local refineries, allowing them to sell it immediately after procurement. Precautions for private gas stations: You get what you pay for—cheaper fuel may not guarantee quality. Although private gas stations are approved by the state, their procurement channels and fuel quality cannot compare to those of the 'Big Three' oil companies. Their attractive selling point is lower prices, and small gifts may make you feel like you're getting a good deal. This follows the principle of small profits but quick turnover, but remember: good products aren't cheap, and cheap products aren't good. It can be used in emergencies, but it's not recommended for frequent use. That said, it's still much better than mobile refueling vehicles. Reasons why private gas stations offer cheaper fuel: The operating costs of private gas stations are relatively low. Since private enterprises usually source their refined oil from secondary distributors, the prices are relatively lower. In terms of operational expenses, private gas stations can hire anyone, even relatives and family members of the owner, to work at the station. This significantly reduces their operating costs, which is why private gas stations typically offer lower prices.

How Many Liters of Power Steering Fluid Are Needed for Replacement?

Changing the power steering fluid requires two liters, with one liter used for flushing. Introduction to Power Steering Fluid Replacement: To prevent fluid deterioration, power steering fluid is generally replaced every 2 years or every 30,000 kilometers driven. The actual replacement interval should be based on the vehicle's condition. If you notice the steering feels heavier, it may be due to deteriorated power steering fluid, which reduces steering assistance effectiveness. Precautions for Power Steering Fluid Replacement: Power steering fluid contains carcinogenic substances. If it comes into contact with skin, wash it off immediately. The fluid is also corrosive and can cause paint to lose its gloss and rubber components to age. If spilled, clean it up promptly.

Do You Need to Press the Brake When Stalling a Manual Transmission Car?

Under normal circumstances, pressing the brake in a manual transmission car will not cause it to stall. The vehicle will only stall if you suddenly press and hold the brake, as the car slows down, the clutch remains engaged, causing the engine speed to drop sharply below idle, leading to a stall. Precautions to Avoid Stalling in a Manual Transmission Car: When starting a manual transmission car, aim for a smooth start. Properly control the clutch and accelerator. Lift the clutch halfway (until you feel a slight vibration from the vehicle), then lightly press the accelerator. At the same time, release the handbrake or brake and slowly lift the clutch. Once the car starts moving slowly, drive for a while before shifting to second gear, remembering to press the clutch quickly but release it slowly. Poor Clutch Control: If the car frequently stalls when starting on a slope, it indicates poor clutch control—likely lifting it too quickly. Starting on a slope is a good test of driving skills. The key is to control the clutch and accelerator properly: hold the clutch steady at the halfway point, release the handbrake and brake, lightly press the accelerator, and then slowly release the clutch. Slope starts require precise clutch positioning—lifting it too quickly can easily cause a stall.

Can the tires be different during annual vehicle inspection?

Vehicle inspection can be conducted with different tire tread patterns, but the left and right tires must have the same tread pattern. Annual inspection requirements for ordinary vehicle tires: The same axle should be equipped with tires of the same model, specification, and tread pattern. The tire bolts and axle bolts should be complete and tightened; the tire specifications should match the motor vehicle product announcement and the motor vehicle factory qualification certificate (for in-use motor vehicle inspection, it should match the motor vehicle registration information); the tire tread and sidewall should not have cracks or cuts exceeding 25mm in length or deep enough to expose the tire cord layer, nor any other defects, abnormal wear, or deformations that affect usage. Annual inspection requirements for passenger vehicles, motorcycles, and trailer tires: The tread depth of the tire crown should be greater than or equal to 1.6mm, and the tread depth of the steering wheel tires for other motor vehicles should be greater than or equal to 3.2mm; the tread depth of the remaining tires should be greater than or equal to 1.6mm, and the tire tread wear indicators should be visible.

What is the appropriate tire pressure for city driving?

The suitable tire pressure for city driving ranges from 2.0 to 2.8 bar. Follow the recommended standard tire pressure value for your vehicle. According to the provisions and requirements of the international GBT2978-2008 standard, the tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum pressure should not exceed 3.5 bar. Hazards of excessive tire pressure: Reduced friction and adhesion of the tire, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, shortening its lifespan; Increases body vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the vehicle while driving; Decreases puncture resistance. When encountering sharp objects such as nails or glass on the road, they can easily penetrate the tire, and the impact may cause internal cracks and explosions, leading to a blowout.
