The internal combustion engine is the main source of power for automobiles and construction machinery, and internal combustion engines mainly include gasoline engines and diesel engines. Diesel engines are widely used in trucks due to their own advantages such as high thermal efficiency, wide application range, and fuel economy. In particular, it can meet the needs of construction machinery operating conditions. Therefore, most construction machinery uses diesel engines as their power source. However, if it is improperly used and maintained, it is prone to overheating failure. Internal combustion engines for construction machinery are more prone to overheating failures due to their complex operating conditions and harsh operating environment. If the overheating fault is not eliminated in time, it will be more harmful and easily cause damage to the mechanical parts, increase fuel consumption, and reduce output power. As a repairer, he often encounters the treatment of the overheating failure of the internal combustion engine during the repair process. So how to quickly and accurately find out the cause of overheating faults and eliminate them in time is very important, which is of great significance for giving full play to the economic and dynamic performance of mechanical equipment and improving its service life. The hazards and causes of internal combustion engine overheating failures are very harmful. Long-term overheating can easily cause deformation, melting, jamming, and cylinder pulling of mechanical parts, which will increase fuel consumption and reduce output power. There are many reasons for the overheating of internal combustion engines, such as heavy load operations on ramps, hot summer and desert plateau areas with high ambient temperature, the cooling system is affected and cannot function fully, long-term overload and high-speed operation conditions, etc. . These are caused by the influence of environmental factors in the operation of construction machinery, and can generally be overcome by improving working conditions and reasonable operation. For the overheating of the body caused by the failure of the internal combustion engine, inspection and maintenance are required to restore normal operation. Overheating caused by internal combustion engine failure mainly includes insufficient cooling water in the cooling system and excessive fouling in the cooling water passage around the cylinder liner, thermostat failure, poor radiator performance, abnormal exhaust valve clearance, incorrect valve phase, and ignition timing failure factors, etc. . Therefore, when the internal combustion engine has an overheating fault, it is necessary to scientifically analyze and judge the fault phenomenon and find the cause of the fault in time.
