The article presents a brief analysis of commonly used and controversial methods for warming up a car engine in very low-temperature conditions. The author considers operational aspects and presents the physics of the operation of engine components and sub-assemblies in the initial phase of its operation.INTRODUCTION
During the operation of a motor vehicle powered by an internal combustion engine, one of the main problems for users is reducing the consumption of fuel and operating fluids, as well as increasing operational reliability, which are parameters that directly affect the vehicle’s operating costs. With the development of environmental protection and the increase in ecological requirements, in addition to the mentioned parameters, the derivatives of operation that have a direct or indirect impact on the natural environment have also been subjected to reduction. Reducing the impact of vehicles on the environment does not always go hand in hand with the requirements and conditions that should accompany the proper use of a vehicle from the point of view of its correct operation and reliability. The article presents a brief analysis of the frequently discussed problem of warming up an internal combustion engine in low-temperature conditions, in terms of the impact of this process on engine components that are particularly exposed to wear, while simultaneously drawing attention to the problem of environmental protection.
Full engine warm-up in low-temperature conditions is a long-term process.
This is accompanied by high fuel consumption and the emission of toxic combustion process compounds. The operation of a cold engine is also accompanied by increased motion resistance and, consequently, the wear of friction elements. (…)
