Diesel National 5 Standard is evaluated based on anti-knock quality, volatility, fluidity, corrosiveness, and stability. The detailed criteria are as follows: 1. Anti-knock quality: The cetane number is the indicator for evaluating the anti-knock quality (ignition performance) of diesel. 2. Volatility: The indicators for evaluating diesel volatility are distillation range and flash point. 3. Fluidity: The indicators for evaluating diesel fluidity are viscosity, freezing point, and cold filter plugging point. 4. Corrosiveness: The indicators for evaluating diesel corrosiveness are sulfur compounds and sulfur content. 5. Stability: The indicators for evaluating diesel stability are total insolubles and 10% carbon residue of distillation residue.

Why does the car display 'service' and fail to start?

This is the vehicle's anti-theft indicator light, indicating that the engine has entered an anti-theft state. Below is an introduction to the car's anti-theft system: 1. Introduction: To enhance anti-theft effectiveness, some vehicles are equipped with a steering lock. The steering lock is used to secure the car's steering shaft. It is integrated with the ignition lock and installed under the steering wheel, controlled by the key. After the ignition lock cuts off the ignition circuit and stops the engine, turning the ignition key to the extreme left position will extend the lock tongue into the steering shaft groove, mechanically locking the car's steering shaft. 2. Types: A car anti-theft device is installed in the vehicle to increase the difficulty and time required for theft, acting as a guardian for the car. By connecting the anti-theft device to the car's electrical circuit, it can prevent theft, intrusion, and protect the vehicle while enabling various functions of the anti-theft device. With advancements in technology, to counter increasingly sophisticated theft methods, various types and structures of anti-theft devices have been developed. These devices can be categorized into four main types: mechanical, chip-based, electronic, and network-based.

What is the reason for the truck bouncing while running?

It is probably because the tire pressure is too high. Here is an introduction to the relationship between car tire pressure and car performance: 1. Tire pressure and load capacity: Tire pressure is an indicator of a car's load capacity. The tire pressure of a car determines its load capacity. The higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity, provided that the tire pressure is within the standard range. 2. The relationship between tire pressure and car power: When the tire is running on a horizontal road, it needs to overcome the resistance of the ground and air. When the tire pressure decreases, the rolling resistance coefficient increases rapidly, the tire rolls and deforms, and fuel consumption rises. Appropriate tire pressure is a guarantee of good car power. 3. The relationship between tire pressure and car ride comfort: The ride comfort of a car is directly related to the comfort of passengers. Appropriate tire pressure can bring better comfort to passengers. When the tire pressure of a car is too high, the tire becomes hard, the vibration frequency of the vehicle increases, and the ride comfort deteriorates. Proper adjustment of tire pressure ensures the ride comfort of the tire.

Prado model features: The Prado is the latest model in the Toyota Land Cruiser series, with excellent power performance and emissions meeting Euro III standards. The advanced engine provides strong output power and torque, paired with a highly robust frame and reinforced suspension system, making even the roughest journeys comfortable and smooth. Prado safety configurations: The domestically produced Prado lacks cruise control, hill start assist control, dynamic stability system, auto-leveling rear suspension, and the most useful A-TRC active traction control for off-road driving, all of which are standard on the imported version. Nonetheless, in terms of active driving safety, the full-time four-wheel drive system still has a positive impact on the Prado.
