What Type of Engine Oil Should Diesel Vehicles Use?

When selecting engine oil for diesel vehicles, you can choose based on quality grade and viscosity grade. The selection should consider factors such as local temperature conditions, the actual condition of the vehicle, and the recommended viscosity for the engine model to pick the appropriate viscosity oil. Diesel engine oil grades are roughly categorized into: CA, CB, CC, CD, CE, CF, CF-4, CG-4, CH-4, CI-4, CJ-4. The different grades of diesel engine oil indicate varying oil quality levels and corresponding suitable vehicle types. In other words, the further the letters are in the sequence, the higher the oil quality grade, and so on. The highest grade of diesel engine oil is: CJ-4. Diesel engine oil grade specifications: The English letter 'C' at the beginning represents diesel engine oil. The further the letters are in the sequence, the higher the oil quality grade. General diesel engines can use CD-grade oil, while turbocharged diesel engines require higher-quality oil, such as CF-4, where '-4' indicates that the oil is suitable for four-stroke diesel engines.

What Causes Pressure in the Car Radiator?

Car radiator has pressure for the following reasons: Water vapor: Gas generated after prolonged engine operation from water or coolant, which is a normal phenomenon. However, once the pressure inside the radiator exceeds the factory-set pressure value of the radiator cap, it will automatically open to release the pressure. If this pressure is not released, it can cause high pressure in the radiator system. Damaged cylinder head gasket: The presence of bubbles or turbulence in the radiator indicates damage to the gasket between the engine block and cylinder head, commonly known as a blown head gasket. During cylinder operation, the piston's reciprocating motion continuously compresses and creates a vacuum. If the head gasket is damaged, the cylinder's compression will directly pressurize the radiator, and during the vacuum phase, it will draw coolant into the cylinder, causing damage to the cylinder interior and lubrication system.

Is it permissible to proceed if the traffic light turns red after the vehicle has already passed the stop line?

If the vehicle has already passed the stop line when the traffic light turns red, it may continue to proceed. When the green light is illuminated, vehicles are permitted to pass. The "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulate the following: Green light: Vehicles are permitted to pass, but turning vehicles must not obstruct the passage of through traffic or pedestrians. Yellow light: Vehicles that have already crossed the stop line may continue to pass. Red light: Vehicles are prohibited from passing. At intersections without dedicated non-motorized vehicle or pedestrian signals, non-motorized vehicles and pedestrians should follow the indications of the motor vehicle traffic signal.

What is the ignition temperature of gasoline in degrees Celsius?

Gasoline has an ignition temperature ranging from 415 to 530 degrees Celsius. Here are some related details about gasoline: Definition: Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through fractionation and cracking, primarily used as fuel. It appears as a transparent liquid, is combustible, and has a distillation range between 3 and 22 degrees Celsius. Its main components include C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Grades: Gasoline has a high octane number (anti-knock combustion performance) and is classified into different grades based on octane ratings, such as 89, 90, 92, 93, 95, 97, and 98. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95 respectively.

What Type of Engine Oil Should Be Used for a Gasoline Generator?

Engine oil can be categorized into summer oil, winter oil, and all-season oil. Therefore, the type of engine oil used for a gasoline generator should be determined based on the generator's model and the regional environment where it is used. It is best to follow the type specified in the vehicle's user manual. Below is an introduction to engine oil: Definition: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10 (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber, earning it the nickname 'the blood of the car.' Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, providing new characteristics, making them an essential part of lubricating oil.

Can I Drive Without the Vehicle Inspection Sticker?

Driving without the vehicle inspection sticker is not allowed. Vehicles with damaged or missing inspection stickers may be stopped by traffic police, fined, and penalized with demerit points during road inspections. If the vehicle inspection sticker is damaged, lost, or destroyed during the validity period of the motor vehicle safety technical inspection and compulsory traffic accident liability insurance, the vehicle owner must submit the vehicle registration certificate to apply for a replacement inspection sticker. The procedure for replacing a vehicle inspection sticker involves bringing your ID card and vehicle registration certificate to the local vehicle management office at the place of vehicle registration. Fill out the sticker replacement application form and submit the documents and application to the staff. The vehicle management office will review the materials. If everything complies with regulations, they will retain the relevant documents, input the information, verify it, and issue a new vehicle inspection sticker. Generally, the new sticker can be obtained within one day. The vehicle inspection process involves driving the vehicle to the nearest inspection station for an exterior check. Cooperate with the staff to complete the motor vehicle exterior registration form, take photos, and log the information. The vehicle will then undergo online inspections, including emissions testing, speedometer testing, brake testing, lighting testing, side-slip testing, and chassis testing. After passing, collect the inspection sticker and affix it to the upper right corner of the front windshield.
