Can different engine oils be mixed together?

Engine oils can be mixed together. If the mixing is done strictly following the mixing principles, it will not have much impact on the vehicle. However, mixing different types of engine oils may cause turbidity. Since different brands and types of engine oils contain different chemical additives, these chemicals may react when mixed, reducing lubrication effectiveness and potentially forming acidic or alkaline compounds that can accelerate corrosion of engine components. The principles for mixing engine oils are as follows: 1. The quality of similar products is basically the same, or when high-quality oil is mixed with low-quality oil, it is still considered as low-quality oil. 2. Adjust the physical and chemical properties of the oil, such as viscosity, so that different grades of the same oil can be mixed. 3. Different types of oils can generally be mixed if it is known that neither of the two mixed oils contains additives, or if one does not contain additives, or if both contain additives but do not react with each other. However, after mixing, the quality of the high-quality oil will be reduced. 4. Ordinary mineral oils can be mixed, and mixing is more feasible between mineral oils and semi-synthetic oils. Mixing full synthetic oils with mineral oils should be done with caution. 5. For oils with unknown characteristics and additive compositions, if mixing is indeed necessary, a mixing test should be conducted beforehand to observe whether there are any abnormal phenomena such as strange odors or sedimentation in the mixed oil. If strange odors or sedimentation are detected, the oils should not be mixed. It is advisable to measure the main physical and chemical properties of the lubricating oil before and after mixing.

What qualifications are included in the new energy qualifications?

New energy qualifications include power transmission and transformation, power engineering, second-class architecture, first-class structure, HVAC, water supply and drainage, hydraulic engineering, environmental protection, engineering economics and budgeting, coal conveying and ash removal, senior power system engineers, etc. The design and development capability requirements for new energy vehicle enterprise access are as follows: 1. Organizational setup: Establish a dedicated R&D institution responsible for the design, development, and improvement activities of new energy vehicles on a long-term basis; for companies under group management, product design and development work can be uniformly established and managed by their parent department/group. 2. Personnel allocation: The educational background, work experience, and technical capabilities of the R&D institution personnel should meet the requirements of their respective positions; review the list of R&D personnel, ID cards, diplomas, professional qualification certificates, labor contracts, salary payments, and social security payment certificates. 3. Job requirements: Overall vehicle layout, as well as structural design of the body, chassis, and frame; vehicle dynamics simulation, matching, and styling design; control principle and strategy framework design, software development, hardware development, and structural design of the vehicle control system; development of communication protocols and data codes between various systems and subsystems; standardization, R&D project management, technical document management, and patent management. 4. Vehicle control: Control strategy framework and control schematic diagram of the vehicle; high-voltage electrical topology diagram, vehicle electrical diagram, wiring harness diagram, and structural diagram of the control system; source code software of the vehicle control system and subsystems, communication protocols for data exchange between systems, failure mode analysis and troubleshooting measures of the control system, etc. 5. Vehicle design: Two-dimensional and three-dimensional overall layout diagrams of the vehicle and simulation analysis documentation of the vehicle power system; integration, matching, selection, and calculation documentation of major systems such as the motor drive system, onboard energy system, DC/DC converter, etc.; simulation analysis of vehicle dynamics, safety, NVH, communication systems, thermodynamics, handling stability, and ride comfort.

What does setup mean on a car?

SETUP button on a car means settings. Here are specific introductions to common car buttons: 1. A-OFF: The button to turn off the engine auto start-stop function. Use this button in congested or waterlogged road sections to ensure normal engine output. 2. AUTO-HOLD: The auto hold button, usually located next to the electronic handbrake. It temporarily shuts off the engine automatically when encountering traffic lights or temporary parking. 3. DUAL: DUAL is the air conditioning zone control button. When the indicator light is on, you can set the air conditioning temperature for the driver and front passenger seat areas. After adjusting to the desired temperature and turning it off, the automatic air conditioning will regulate the temperature according to the set values.

What is the real fuel consumption of the BYD Song 1.5t?

BYD Song 1.5t has a combined fuel consumption of 7.4L/100km. There are currently 4 models of BYD Song 1.5t on sale: Automatic Elite, Manual Luxury, Manual Comfort, and Automatic Luxury, all with a combined fuel consumption of 7.4L/100km. The above figures are NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The real fuel consumption is higher than this value, ranging from 8.33-11.56L/100km. Specific factors affecting car fuel consumption are as follows: Car weight: The larger and heavier the car, the higher the fuel consumption. Generally, a small family car with a 1.6L displacement weighs about 1.2 tons, with fuel consumption around 7.5 liters (calculated under full load), while an SUV model weighs about 1.5 tons, with fuel consumption around 8.5 liters. Different weights lead to different fuel consumption. Wind resistance: Higher wind resistance increases fuel consumption during driving. Cars with better aerodynamics have lower wind resistance, resulting in lower fuel consumption. Economical RPM: During driving, the engine has a most economical torque output point. If the car's speed remains within this torque output point for a long time, fuel consumption will be significantly reduced. Generally, small-displacement cars reach this point at about 70 km/h, while large-displacement cars reach it at about 100 km/h. Maintaining this economical RPM range ensures minimal fuel consumption. Driving style: Aggressive driving, such as sudden acceleration, frequent overtaking, or not easing off the throttle before a red light, will increase fuel consumption.

Which one indicates empty fuel in 'ef'?

On the car fuel gauge, 'E' stands for the abbreviation of the English word 'EMPTY', indicating no fuel; 'F' stands for the abbreviation of the English word 'FULL', indicating a full tank. The car fuel gauge is an indicator used to display the remaining fuel in the vehicle, serving as an important reference for drivers to determine whether to refuel. By understanding the structure and meaning of the fuel gauge, drivers can accurately assess the remaining fuel or whether the fuel gauge is functioning normally. Here is some additional information: The fuel gauge is located directly in front of the driver's position, on the same dashboard as indicators for water temperature, RPM, speed, etc., with each gauge distinguished by a simple icon. The pointer fuel gauge has two English letters—E and F. 'E' stands for 'EMPTY', indicating no fuel; 'F' stands for 'FULL', indicating a full tank. If the pointer is approaching 'E', it is necessary to refuel immediately.
