We know that when a diesel engine<\/strong><\/em><\/a> converts the energy contained in diesel (usually called LHV: Low Heat Value) into mechanical energy and outputs it through a flywheel, its efficiency is not high (usually about 40%). The reason is that most of the energy (about 60%) is converted into heat energy and taken away with the engine coolant and exhaust gas discharged from the engine. If the engine cannot dissipate heat through the cooling system, the metal mechanical parts and oil of the engine will overheat, thereby destroying their physical and chemical properties, affecting output power, and shortening the service life of the engine.<\/span><\/p>\n

The cooling system must take away heat to keep the engine running in the proper temperature range (engines are usually measured by the jacket water outlet temperature, and 89\u00b0C to 98\u00b0C is appropriate). The harmful effects of overheating of the engine have been explained above, but the cooling system of the engine is not as cold as possible. Overcooling can also cause serious injuries such as cylinder pulling.<\/span><\/p>\n

Having said that, by the way, explain the “warm-up” problem that needs to be paid attention to when using a car: when the car engine has just started and the water temperature has not risen to the normal operating temperature range, it is not advisable to let the engine output excessive power. Whether it is in winter or summer, whether in the north or south, it is best to wait for the engine water temperature gauge to move before starting on the road. It is just that the warm-up time required in the severe summer in the south is greater than that in the cold winter in the north. The time is so short that we all forget the process.<\/span><\/p>\n

The cooling system usually consists of coolant, thermostat, water pump, engine water jacket, oil cooler, intercooler and radiator. Some machines also include water-cooled exhaust manifolds, water-cooled turbochargers, etc. The maintenance work of the engine cooling system includes the inspection of all the above components. The workload is quite large. Today we only choose the coolant for discussion.<\/span><\/p>\n

Coolant is usually mixed with water and additives with functions such as rust prevention, and antifreeze is added in addition to the above two components in cold areas. The correct choice of coolant will directly affect the efficiency and service life of the cooling system and the engine.<\/span><\/p>\n

The antifreeze is not a consumable product in the strict sense, so there is no need to replace it in a short time. There are two main reasons for the deterioration of antifreeze. The first is the loss of internal volatile substances after a long time of use, which causes the freezing point and boiling point to decrease; the second is that the organic liquid in the antifreeze dissolves in a large amount of water channels and pipelines after a long time. Of organic matter, causing turbidity and even deterioration.<\/span><\/p>\n

Determining whether the antifreeze is deteriorating is not simply relying on visual observation for discoloration, or relying on time to calculate. The correct method is to measure with professional instruments. When the detected value is lower than the standard, the antifreeze fluid needs to be replaced.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
