Changan CS55 uses Shell HX7 5w-40 synthetic engine oil, with an oil capacity of approximately 4 liters. Below is relevant information about engine oil: 1. Functions: Engine oil, also known as engine lubricant, serves multiple purposes including lubrication and wear reduction, auxiliary cooling, sealing against leaks, rust and corrosion prevention, as well as shock absorption. 2. Classification: Gasoline engine oils are divided into two categories: mineral oils and synthetic oils. Synthetic oils are further classified into semi-synthetic and full-synthetic engine oils. 3. Composition: Engine oil consists of two main components: base oils and additives. Base oils form the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the performance limitations of base oils, imparting new characteristics. Additives are crucial components of lubricants.

Is it normal for the idle speed to drop from 800 to 600 rpm?

If the car's idle speed was previously 800 rpm and has now dropped to 600 rpm, this situation is abnormal. Common causes for this phenomenon include dirty or clogged intake systems, engine misfiring or poor working conditions, and clogged three-way catalytic converters in the exhaust system. Dirty or clogged intake system: During vehicle use, components such as the throttle body, air filter, and idle control valve can easily accumulate dirt and become clogged. Once clogging occurs, the engine's idle speed will become lower and unstable, making it difficult to start and prone to stalling. The solution is to inspect the intake system for dirt or clogging every year and a half or two years, and clean it promptly if necessary. Engine misfiring or poor working conditions: Check the aging level of ignition coils and spark plugs, inspect whether the fuel injectors are clogged or damaged, and check for any damage to the control unit wiring. Faults in the ignition system can lead to poor acceleration and engine shaking at idle. The solution is to inspect and repair the ignition system, replacing components as needed. Clogged three-way catalytic converter: When the engine operates under poor conditions for extended periods, it can cause the three-way catalytic converter to become clogged. Symptoms include low idle speed and a muffled engine sound. The solution is to replace the three-way catalytic converter or clean it.

Why Are There No Black Minivans?

The reasons why there are no black minivans on the market are as follows: 1. Cost reasons: Minivans are often positioned as lower-end MPVs, and due to their positioning, costs need to be minimized as much as possible. Offering more paint colors would inadvertently increase costs. 2. Market reasons: Black cars absorb heat significantly, requiring higher air conditioning usage in summer. Black cars also show dirt more easily and need frequent cleaning; otherwise, they appear older than other colors. Additionally, black makes cars look smaller, which is not ideal for already compact vehicles, especially minivans with simple lines, resulting in poor visual appeal. These factors contribute to the lack of popularity for black minivans in the market.

What Causes the Engine Malfunction Light to Illuminate and Acceleration to Feel Weak?

This is caused by an engine malfunction. It is recommended to use a diagnostic tool to read the engine's fault codes. Below is an introduction to relevant information: 1. General Situation: Generally, when a car has been driven for 20,000 kilometers, attention should be paid to cleaning the throttle body. The fuel injectors should be cleaned between 20,000 to 30,000 kilometers. If the vehicle is in good condition and the fuel quality is high, cleaning can be delayed until 40,000 to 60,000 kilometers. 2. Three-Way Catalytic Converter: The three-way catalytic converter should be cleaned every 30,000 kilometers. If the vehicle is well-maintained with good fuel quality and condition, it can last until the end of the catalytic converter's lifespan (typically 30,000 to 50,000 kilometers). Additionally, cleaning the fuel injectors, throttle body, or three-way catalytic converter separately is not advisable. While cleaning the fuel injectors and throttle body individually can improve fuel efficiency and enhance power, the effect is not significant.
