Repair without extraction from the car of the diesel engine The given Part of the Head is devoted the repair of the diesel engine which has been not connected with its extraction from the car (in situ).The description большей parts of considered procedures is made, proceeding from the assumption that the power unit remains on the regular place in an impellent compartment of the car. In view of told, in a case if the engine is already dismantled and established on a workbench or the assembly stand, many of described steps should be lowered. Let's notice that despite physical possibility of performance of repair in situ such components as shatunno-piston assemblages, this sort of works are usually made after dismantling of the engine in view of necessity of carrying out of some auxiliary procedures, not to mention requirements to observance of cleanliness of details and absolute passableness маслотоков. The general description of the engine The considered engine concerns family of 4-cylinder diesel engines with рядным an arrangement of cylinders, the top arrangement of a camshaft (OHC) and water cooling. The engine is established cross-section in a forward part of the car and inclined forward at an angle 14 °. Transmission and coupling assemblages are in the left part of the power unit. In a head of cylinders the camshaft which drive is carried out by a zubchato-belt drive from a cranked shaft is established. In запрессованные in a head body directing plugs are planted inlet and final valves. Closing of each of valves occurs at the expense of the effort developed by a unique screw spring. Camshaft cams influence valves directly through the hydraulic pushers planted in individual nests. Oil giving in hydrojacks and for greasing of pushers is carried out through the heads cast in a body маслотоки. For a complete set of cars Skoda Felicia diesel engines with indirect injection of fuel are used - in a head of cylinders replaceable vortical chambers are built in. The cranked shaft is established in five radical bearings. The bearing established between the second and third cylinders, is persistent and supervises axial люфт a shaft. Resulted in rotation газораспределительным the intermediate shaft provides with a belt functioning of the vacuum pump of the amplifier of brakes and the oil pump of system of greasing of the engine. Circulation of a cooling liquid is provided with the water pump put in action from an auxiliary belt. Details by a principle of functioning of system of cooling can be obtained from materials of the Head of System of cooling, heating. The compulsory system of greasing of the engine is organised by means of the pump put in action is direct from an intermediate shaft. The fence of oil from the pallet картера is carried out through equipped with the mesh filter маслозаборник. Before giving in a contour of greasing of the engine oil is banished through established outside полнопоточный the oil filter of replaceable type. Having passed through the filter, oil arrives in a head of cylinders where it is used for greasing подшипниковых necks of a camshaft and hydraulic pushers of valves, and further, in картер the engine, to radical and шатунным to bearings, piston fingers and mirrors of cylinders. In the basis of each of cylinders the sprays providing giving of oil in подпоршневое space for the purpose of increase of efficiency of a heat-conducting path are built in. Included in a path of system of cooling маслоохладитель lowers oil temperature before its giving in the engine. On factory Skoda the engine arrives without the hinged equipment (besides power supply system equipment) and already on the conveyor is completed with the generator, water and steering pumps. A drive of auxiliary units it is carried out by a belt drive. The list of the repair procedures, which performance does not demand extraction of the engine from the car Procedures of repair and the engine service which performance can be made in situ are more low listed: a) Removal and installation of a belt of a drive of auxiliary units; b) Removal and camshaft installation; c) Replacement of an epiploon of a camshaft; d) Removal and installation of a cogwheel of a camshaft; e) Removal and installation of the water pump (see the Head of System of cooling, heating); f) Replacement of epiploons of a cranked shaft; g) Removal and installation of a cogwheel of a cranked shaft; h) Removal and installation of a head of cylinders; i) Check of a condition and replacement of support of a suspension bracket of the power unit; j) Replacement of an epiploon of an intermediate shaft; k) Removal and installation of the oil pump and assemblage маслозаборника; l) Removal and pallet installation картера; m) Removal, check of a condition and installation of a belt of drive ГРМ from cogwheels and a forward cover. |
