Is the Hongqi H9 engine from Audi?

Hongqi H9's engine does not belong to Audi. Relevant information is as follows: 1. Audi's engines are independently produced by FAW in China. The models are equipped with two types of engines: the CA4GC20TD-31, a 2.0-liter turbocharged four-cylinder engine with 252 horsepower, featuring a 48V mild hybrid system, and the CA6GV30TD-03, a 3.0-liter supercharged six-cylinder engine with 283 horsepower. 2. The engines of the Hongqi H9 are all independently developed by FAW. The H9 offers two engine options for consumers: a 2.0T turbocharged engine with a maximum horsepower of 252 and a maximum torque of 340 Nm, and a 3.0T supercharged engine with a maximum power of 283 horsepower and a maximum torque of 400 Nm.

What is the original oil specification for Volkswagen EA211?

The original oil specification for Volkswagen EA211 is VW50200. Relevant information is as follows: 1. VW50200 is Volkswagen's own set of standards. The SN-grade 5W40 oil is compatible with the VW50200 standard. SN is the oil quality grade standard established by the American Petroleum Institute (API). S stands for gasoline engines, while C represents diesel engines. The performance grades of oil are ranked starting from A, currently up to P, so SP is the highest quality grade standard. 2. 5W40 is an all-season oil. 5W indicates that this oil can ensure normal engine startup at a minimum ambient temperature of -30°C. 40 indicates that the fluidity of this oil at 100°C is 14.5cst. Overall, 5W40 is still an oil with relatively high high-temperature viscosity, typically used only by German cars such as Volkswagen and Audi.

What are the consequences of suddenly shifting to P gear while driving?

Here are the hazards of shifting to P gear while driving: 1. Accidentally shifting to P gear in an automatic transmission while driving can damage the locking mechanism inside the transmission and easily damage the gear shift switch inside the transmission. Never shift directly to P gear before the vehicle has come to a complete stop, as this can easily cause damage to the pawl inside the transmission. Therefore, always ensure the vehicle is fully stopped before shifting to P gear. 2. The working principle of the P gear in the transmission is actually similar to that of the N gear, both of which separate the gears to block the power transmitted from the engine to the wheels. However, the P gear has an additional parking gear and pawl compared to the N gear in its structure. When shifted to P gear, the pawl tightly locks the gear on the output shaft, forming a mechanical lock, thereby securing the drive axle and fixing the stationary vehicle.

Why does a new car shake severely during cold start?

Reasons for severe shaking during cold start: 1. Low ignition energy causing vibration. When the engine temperature is too low, both fuel and lubricant temperatures are low. During cold start, a richer air-fuel mixture is required, which in turn demands higher ignition energy. Excessive spark plug gap or aging ignition coils/high-voltage coils can all lead to decreased ignition energy, resulting in vehicle shaking. 2. Incorrect air-fuel mixture ratio causing cold start vibration. When certain engine sensors provide significantly erroneous signals, the ECU makes incorrect judgments, leading to errors in fuel injection timing and ignition timing control, which manifests as engine shaking. 3. Uneven cylinder conditions causing engine vibration. In multi-cylinder engines, significant differences in ignition energy between cylinders may occur. Additionally, varying degrees of piston and piston ring wear result in inconsistent compression ratios, causing uneven power output and engine shaking.

How to Fix P1604 Trouble Code?

This trouble code indicates a starting system malfunction. Since professional tools are required for diagnosis and repair, it is recommended to visit an auto repair shop or 4S dealership for inspection. Below is some information about the P1604 trouble code: 1. The P1604 trouble code signifies a starting system malfunction in Chinese. There are generally two causes for this code: unsuccessful starting due to insufficient oil pressure, or difficulty starting the vehicle after disconnecting the battery cables. 2. After troubleshooting the vehicle issue, the trouble code must be cleared. When clearing the trouble code, strictly follow the specific clearing method prescribed for your vehicle model. Never attempt to clear the code by simply disconnecting the negative terminal of the battery.

What is the difference between horsepower and power?

Power is measured in kilowatts, and both horsepower and kilowatts are units of power, but there is a difference between the power represented by 1 horsepower and 1 kilowatt. Here is the relevant information: 1. The conversion between horsepower and power is 1 horsepower equals 735 watts or 0.735 kilowatts. The United States and the United Kingdom commonly use imperial horsepower, where 1 horsepower equals 0.985 imperial horsepower. Horsepower has been abolished from China's legal measurement units, and now engine power is labeled in kilowatts. 2. Horsepower is a commonly used unit of power in engineering, proposed by James Watt. 1 horsepower is approximately equal to 735 watts. It generally refers to metric horsepower rather than imperial horsepower. Power refers to the amount of work done by an object per unit of time, meaning power is a physical quantity that describes how fast work is done.
