2.46.1. Diagnostics of malfunctions of mechanisms of the engine
Typical malfunctions of mechanisms of the engine and their possible reasons are more low described. After failure detection it is necessary to eliminate its reason, having performed corresponding works on adjustment, repair or replacement of details and knots. The big expense of engine oil – A leak of oil from the engine. To tighten bolts and-or to replace linings and consolidations. – Wrong definition of level of oil on щупу. To check up oil level on the car established on a horizontal platform after oil will flow down in the pallet. – Application of unrecommended engine oil. It is necessary to use the engine oil which viscosity on classification SAE corresponds to prevailing service conditions of the car (a range of temperatures of air). – The forced modes of operation of the car, for example, frequent movement on high speeds and trailer towage naturally lead to increase in the expense of oil. – Malfunction of system of compulsory ventilation (СПВ) картера the engine. – Deterioration of consolidations of cores of valves and-or directing plugs. To develop plugs for the repair size and to establish new valves with the increased diameter of a core and-or to replace consolidations. – Breakage or deterioration of piston rings, закоксовывание rings. To replace faulty rings, to clean rings and flutes. – Wrong installation of pistons. Low pressure of oil – Small frequency of rotation of a cranked shaft idling the engine. To adjust idling turns. – Malfunction of the gauge of pressure of oil. – Malfunction of the index of pressure of oil. To replace the index. – Insufficient viscosity of oil or pollution of oil by impurity. To replace engine oil with the recommended mark for prevailing service conditions of the car. To merge polluted by fuel or a cooling liquid oil and to fill in the fresh. – Deterioration or pollution of the oil pump. – Zabivanie of the oil filter. – Easing of fastening or забивание the reception oil filter. – An aperture in a reception branch pipe of the oil pump. – Deterioration of loose leaves of bearings. To replace loose leaves if necessary. – Cracks, a time in walls of oil channels or забивание oil highways. To repair or replace the block of cylinders. – Absence or wrong installation заглушек oil channels. To establish заглушки. Engine overheat – Leak of a cooling liquid, leak in system of cooling of oil, malfunction of a broad tank. To check up system on presence of leaks and to eliminate malfunctions. To check up serviceability of a broad tank, hoses and a radiator cover. – Proskalzyvanie or rupture приводного a belt. To replace натяжитель or a belt. – The thermostat is faulty (is constantly closed). To check up the thermostat and to replace if necessary. – The electric fan is faulty. – The lining of a head of the block of cylinders is faulty. To check up and if necessary to replace. The signalling device of pressure drop of oil is included at engine work idling – Oil highways and-or highways of a cooler of oil are littered. To clean highways. – Low pressure of the oil pump. |
