The engine is regarded as the heart of the car, so it can be seen that the engine is very important for the car, and the use of gasoline has an important influence on the engine. Some owners may mix oils under certain circumstances. For example, if there are no 93 fuels at some gas stations, the owners will choose to use 90th oil instead, but after the replacement, the vehicles do not feel strong during the driving process. There may be difficulties in speeding up. Then, let's take a look at the impact of different oil blends on the engine.
First of all, from the technical point of view, the additives and chemical composition of gasoline with different numbers, such as No. 90 gasoline, No. 93 gasoline and No. 97 gasoline, are all different. Therefore, the use of different grades of gasoline blended together will certainly affect the vehicle. The damage caused, especially the long-term mixed use of oil products by vehicle owners, should not be underestimated. The engine of each car has its most suitable marking oil.
The determination of vehicle marking oil is actually determined based on the compression ratio of the engine. In general, the higher the compression ratio of the engine, the higher the required oil number. Because the general engine's ignition control system will often set different ignition timings according to different label oils, this parameter will basically not change once it is set.
To give a simple example, if the vehicle originally used 93 oil, but later changed to the use of 90 oil, the engine will continue in the early stage is the ignition time of 93 oil, so that the engine is likely Knocking may occur, so it is very serious to use different oils with different markings to damage the engine. In particular, the reduction of marking oils into automobiles with high-grade oil for a long period of time not only causes insufficient combustion of fuel, but also the internal oil passages of the vehicles, resulting in insufficient output power of the vehicles. The long-term use will also cause serious engine damage!
A heat exchanger is a device used to transfer heat, usually to transfer heat from one fluid to another without them mixing. A heat exchanger usually consists of a number of parallel pipes in which one fluid flows through the pipe and another fluid flows through the outside of the pipe. In this way, heat can be transferred from one fluid to another for heating or cooling purposes. Heat exchangers are widely used in many industries, such as chemical, pharmaceutical, food processing, air conditioning and heating systems, etc.
Heat exchanger usually consists of the following components:
1. Heat exchange pipe: Pipe used to transfer heat, usually made of metal materials, such as copper, stainless steel, etc.
2. Heat exchange surface: A surface used to transfer heat, usually consisting of metal sheets or pipes. The greater the surface area, the higher the heat transfer efficiency.
3. Housing: Housing, usually made of metal or plastic, used to secure heat exchange pipes and surfaces.
4. Seals: Seals used to prevent media leakage, usually made of rubber or silicone rubber.
5. Support: A support used to support a heat exchanger, usually made of steel or cast iron.
6. Import and export pipes: pipes used for medium entry and exit, usually made of metal or plastic.
7. Cleaning hole: A hole used to clean the inside of the heat exchanger, usually located on the upper or side of the heat exchanger.
8. Insulation layer: Insulation layer used to keep the temperature of the heat exchanger stable, usually made of glass wool or polyurethane foam.
