Where to Check the Vehicle Production Date?

There are three ways to check the vehicle production date: 1. The production date is located below the B-pillar on the passenger side, visible upon opening the door, but this plate only specifies the year and month. 2. The certificate of conformity that comes with the new vehicle, located in the upper right corner of the certificate, where the production date is marked and can be specified to the exact day, month, and year. 3. The vehicle's chassis number, like an ID card, contains the production date. The chassis number, also known as the Vehicle Identification Number (VIN), is a set of seventeen letters and numbers used to represent vehicle information. The tenth letter or number in the chassis number indicates the vehicle's production date, with the year code repeating every 30 years.

How to Perform Pressure Testing for Leak Detection in Car Air Conditioning?

Car air conditioning pressure testing for leak detection is performed as follows: 1. Properly connect the air conditioning pressure gauge to the high and low pressure pipelines of the air conditioning system (red for high pressure, blue for low pressure), then connect the air pump to pressurize the system. 2. After pressurization, close the high and low pressure valves on the pressure gauge, let it sit for 10-15 minutes, observe the pressure gauge needle to check for any leaks in the air conditioning system and locate the leak points. Notes for pressure testing for leak detection: 1. The pressure for car air conditioning testing is generally around 20-30 Bar, which is higher than the working pressure of the car air conditioning system. 2. Ensure that leak detection is completed before proceeding with vacuuming the air conditioning system and adding refrigerant. After completing the pressure testing for leak detection and vacuuming, you can directly add the refrigerant.

How Many Spark Plugs Are There in a Car?

Generally, a car follows the principle of one spark plug per cylinder. For example, a four-cylinder engine corresponds to four spark plugs. However, there are exceptions where some cars have two spark plugs per cylinder, with the Nissan Bluebird U11 being a typical example. What is a Spark Plug: A spark plug is a crucial component of the ignition system in a gasoline engine. It introduces high-voltage electricity into the combustion chamber and causes it to jump the electrode gap to produce a spark, thereby igniting the combustible mixture in the cylinder. What Does a Spark Plug Consist Of: A spark plug mainly consists of a terminal nut, an insulator, a terminal stud, a center electrode, a side electrode, and a shell. What Types of Spark Plugs Are There: The main types of spark plugs include standard spark plugs, projected insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs.
