Repair without extraction from the car of the diesel engine This Part of the Head is devoted to the repair of the diesel engine which is not connected with its extraction from the car (in situ).The description of the most part of the considered procedures is made, proceeding from the assumption that the power unit remains on the regular place in a motive compartment of the car. In view of told in case the engine is already dismantled and installed on a workbench or the assembly stand, many of the described steps have to be lowered. Let's notice that despite physical capacity of performance of repair of in situ of such components as conrod and piston assemblies, works of this sort are usually performed after dismantling of the engine in view of need of holding some auxiliary procedures, not to mention requirements to respect for purity of details and absolute passability of maslotok. General description of the engine The considered engine concerns to family of 4-cylinder diesel engines with a line arrangement of cylinders, the top arrangement of the camshaft (OHC) and water cooling. The engine is installed cross in a forward part of the car and inclined forward at an angle 14 °. Assemblies of transmission and coupling are in the left part of the power unit. In a head of cylinders the camshaft which drive is carried out by the gear belt drive from a bent shaft is installed. In the directing plugs pressed in a body of a head inlet and final valves are put. Closing of each of valves happens due to the effort developed by the only screw spring. Cams of the camshaft influence valves directly through the hydraulic pushers put in individual nests. Supply of oil in hydrocompensators and for lubricant of pushers is carried out through the maslotoka heads cast in a body. For a complete set of the Skoda Felicia cars diesel engines with indirect injection of fuel are used - in a head of cylinders replaceable vortex cameras are built in. The bent shaft is installed in five radical bearings. The bearing installed between the second and third cylinders is persistent and controls an axial side play of a shaft. The intermediate shaft given to rotation by a gas-distributing belt provides functioning of the vacuum pump of the amplifier of brakes and the oil pump of the lubrication system of the engine. Circulation of cooling liquid is provided with the water pump put in action from an auxiliary belt. Details by the principle of functioning of the cooling system can be obtained from materials of the Head of the Cooling system, heating. The compulsory lubrication system of the engine is organized by means of the pump put in action directly from an intermediate shaft. The oil intake from the pallet of a case is carried out through the maslozabornik equipped with the mesh filter. Before giving in an engine lubricant contour oil is banished through the full-line oil filter of replaceable type established outside. Having passed through the filter, oil comes to a head of cylinders where it is used for greasing of bearing necks of the camshaft and hydraulic pushers of valves, and further, in an engine case, to radical and conrod bearings, piston fingers and mirrors of cylinders. In the basis of each of cylinders the sprays providing supply of oil in subpiston space for the purpose of increase in efficiency of the heat sink are built in. The oil cooler which is switched on in the highway of the cooling system lowers oil temperature before giving it in the engine. On the Skoda plant the engine arrives without the hinged equipment (besides the power supply system equipment) and already on the conveyor is completed with the generator, water and steering pumps. The drive of auxiliary units it is carried out by the belt drive. The list of repair procedures which implementation does not demand extraction of the engine from the car Procedures of repair and service of the engine which implementation can be made by in situ are listed below: a) Removal and installation of a belt of the drive of auxiliary units; b) Removal and installation of the camshaft; c) Replacement of an epiploon of the camshaft; d) Removal and installation of a cogwheel of the camshaft; e) Removal and installation of the water pump (see the Head of the Cooling system, heating); f) Replacement of epiploons of a bent shaft; g) Removal and installation of a cogwheel of a bent shaft; h) Removal and installation of a head of cylinders; i) Check of a state 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 assembly of a maslozabornik; l) Removal and installation of the pallet of a case; m) Removal, check of a state and installation of a belt of the GRM drive with cogwheels and a forward cover. |
