Many motorists have come across the concept of car engine repair. But not everyone understands what this process is. Not every car owner can repair his car, since many simply do not know what technology for repairing a car engine is. This article will tell you about the main processes of restoring the power unit.
Repair of gasoline engines is a rather complex process of restoring worn out units and parts of a power unit to its original state or close to it. This process includes many operations and depends on the type and class of the motor.
During the operation of a vehicle, many motorists do not pay attention to maintenance, which plays a very important role in the condition of the power unit, as well as its resource. Subsequently, it may happen that the repair of the gasoline engine will not be possible. Therefore, the restoration of the power unit is affected not only by physical wear, but also by how it is looked after.
Let's consider in what cases the engine will have to be repaired:
How to classify the repair of gasoline engines:
Many motorists ask themselves the question - where to start repairing gasoline engines? The answer is quite simple - it is necessary to determine the signs: is it generally necessary to repair the unit, or the problem lies in something else? This will require a number of diagnostic procedures. They are divided into 2 types: electronic and mechanical.
Electronic diagnostics can show whether auto repair is necessary in terms of electronics and whether there are any problems at all. For this, the electronic engine control unit is checked, as well as the condition of all sensors and connections. If the problem is not identified, then you should not go further, because you can create a problem that will have to be solved.
Mechanical diagnostics will require a lot of time, effort and knowledge. There are instructions for carrying out this operation on the Internet, but in this article we will try to explain everything in a much more detailed and understandable way. If problems were found in the process of carrying out diagnostic operations, then gasoline engines will have to be disassembled and repaired.
Hand hygiene has become paramount in the face of the COVID-19 epidemic. The demand for sanitizers has skyrocketed around the world. Antiseptics are included in the list of essential goods along with medical masks, hygiene products and baby products. Let's take a closer look at which antiseptics can be used for coronavirus and how effective their protection is.
Before deciding which antiseptic for coronavirus is best, let's consider for what purposes it is used.
An antiseptic is a disinfectant necessary for disinfecting medical instruments and maintaining hygiene in cases where it is not possible to wash your hands with soap and water. The product is used for external use only. It differs in composition and form of release (foam, spray, gel, etc.). Alcohol is more often used as an active substance.
Against the background of the epidemic, the demand for disinfectants has grown significantly. Due to the large assortment of sanitizers, it is quite difficult to determine which antiseptic to buy for the coronavirus. In order not to make the wrong choice, it is important to know what COVID-19 is and how the disease spreads.
COVID-19 belongs to the group of viral respiratory infections. The causative agent of the disease is a simple microorganism, which is RNA with a lipid and protein envelope. Due to protein spikes, the virus easily attaches to any surface and remains active for up to several days.
Infection can occur in two ways:
Washing your hands with soap and hot water is the best way to protect yourself from infection. The alkali present in the soap effectively acts on the virus, damaging its spines and protein coat. Hot water leads to protein denaturation, due to which the pathogen loses its natural properties and the ability to invade the cell.
Disinfectants work in a similar way. The active substances they contain accelerate the decay process and destroy the protein coat of the pathogen. However, not all hand sanitizers are effective against coronavirus. To eradicate COVID-19, the sanitizer must contain over 70% alcohol. Solutions with a lower concentration are useless for disinfection.
