What does ILSAC engine oil mean?

ILSAC stands for the International Lubricant Standardization and Approval Committee, which was jointly established by the American Automobile Manufacturers Association and the Japanese Automobile Manufacturers Association. It is an organization that certifies lubricant product specifications, with its certifications issued by the American Petroleum Institute (API). ILSAC has established gasoline engine oil specifications as GF-1, GF-2, GF-3, GF-4, and GF-5. In addition to meeting all the requirements of API SH, SJ, SL, SM, and SN respectively, GF-1, GF-2, GF-3, GF-4, and GF-5 must also comply with the EC energy-saving requirements set by ILSAC. The energy-saving standards are as follows: 1. GF-1 is equivalent to SH plus energy-saving requirements; GF-2 is equivalent to SJ plus energy-saving requirements. 2. GF-3 is equivalent to SL plus energy-saving requirements; GF-4 is equivalent to SM plus energy-saving requirements. 3. GF-5 is equivalent to SN plus energy-saving requirements.

What does BRS mean in a car?

In cars, BRS is commonly found in the sound quality adjustment modes of the car audio system, which typically includes four modes: BRS, TRE, FRD, and FRL. BRS stands for bass, TRE stands for treble, FRD stands for front-rear, and FRL stands for left-right. Additional information: 1. A subwoofer usually has at least two knobs: one controls the volume, and the other adjusts the range of low-frequency sounds. Generally, setting the low frequency around 150Hz will make the speaker sound more subdued. Simply adjust the subwoofer's volume knob to lower the sound until you can hear both the bass and the front speakers clearly. 2. While adjusting, always play music to listen to the sound and adjust it to your preferred tone. Sound quality should be adjusted according to personal preference, as different discs have varying sound qualities, and there is no one-size-fits-all setting.

What is the Difference Between Mobil and Castrol Engine Oil?

Castrol and Mobil each have their own characteristics, with different performance focuses. The differences between the two are as follows: 1. Castrol engine oil contains titanium particles, known as titanium fluid. Utilizing the adsorption properties of titanium particles, after each engine shutdown, a protective titanium film forms on the friction parts of the combustion chamber and pistons, achieving "protection before starting." Additionally, regular use of Castrol can help fill minor damages in the engine cylinders with titanium. 2. Mobil engine oil emphasizes long-lasting performance, meaning it has a longer oil change interval. This is because Mobil uses an exclusive polyalphaolefin (PAO) base oil, with neatly arranged molecules that provide excellent oxidation resistance and high-temperature performance. Its viscosity changes little, making it more suitable for long-term use. Furthermore, this brand offers good noise reduction. However, its drawback is that under high RPM conditions, the engine may experience insufficient power output.

Is It Normal to See Black Smoke When Accelerating Hard?

The phenomenon of black smoke when accelerating hard is not normal. The essence of black smoke is incomplete combustion, and the reasons for incomplete combustion are as follows: 1. Air intake issues: A clogged or contaminated air filter is the most common cause. The first step in diagnosing this issue is often to check the air filter. 2. Poor air supply due to wear in the air supply system. This problem requires a 4S inspection to identify the root cause. Worn turbochargers, clogged air filters, and poor driving habits leading to malfunctioning solenoid valves and inadequate lubrication may be the reasons for insufficient air supply. 3. Poor fuel supply: Due to substandard fuel quality, high viscosity and ash content (impurity levels), the fuel injector solenoid valves may wear out, clog, or accumulate carbon deposits, affecting their sealing performance. This ultimately leads to an abnormal air-fuel mixture ratio, incomplete combustion, and black smoke. Common causes of poor fuel supply also include clogged fuel systems due to dust and particulate matter. 4. Malfunctioning solenoid valves. Dust and particulate matter in the air can damage solenoid valves, leading to insufficient turbocharging, reduced air density, and incomplete combustion.

What Causes the Vehicle Stability Control System Light to Illuminate?

The illumination of the Vehicle Stability Control System light indicates a malfunction in the vehicle's ESP (Electronic Stability Program). When the ESP light comes on during driving, it is necessary to reduce speed, avoid excessive steering and turning, and promptly locate a nearby 4S dealership to diagnose the issue. ESP, or Electronic Stability Program, is an automatic vehicle stability control system. The ESP system primarily consists of three major components: sensors, actuators, and the electronic control unit (ECU). Sensors typically include wheel speed sensors, steering angle sensors, lateral acceleration sensors, yaw rate sensors, and brake master cylinder pressure sensors. Actuators generally comprise conventional braking systems and hydraulic controllers, while the electronic control unit interacts with the engine management system to intervene and adjust engine power output. Common ESP malfunctions include: ABS pump failure and ABS pump power supply grounding circuit faults, loose sensor connectors or failure of a specific sensor function, related fuse blowouts or burnouts, obstruction of system signal transmission, false faults (system false alarms). Try pressing the off button to restart the system.

What vehicles can a K2 driver's license drive?

K2 driver's license can drive passenger vehicles with a length of less than 6 meters. Here is the extended information: 1. Applicants for K1 class "Driving Permit" must have more than 4 years of safe driving experience or a safe driving mileage of more than 100,000 kilometers; 2. Applicants for K2 class "Driving Permit" must have more than 2 years of safe driving experience or a safe driving mileage of 50,000 kilometers; 3. Applicants for H1 class "Driving Permit" or those who need to have the word "dangerous" marked on the H class "Driving Permit" must have more than 2 years of safe driving experience or a safe driving mileage of more than 50,000 kilometers. Here is the classification of Driving Permits by vehicle type: 1. K1 class, passenger vehicles with a length of 6 meters or more; 2. K2 class, passenger vehicles with a length of less than 6 meters; 3. H1 class, freight vehicle trains (semi-trailers and full trailers); 4. H2 class, ordinary freight vehicles; 5. H3 class, other motor vehicles. 6. Driving dangerous goods transport vehicles requires the word "dangerous" to be marked on the corresponding H class Driving Permit.
