3.1. 1,4 and 1,6 liters petrol engine

In this part of the Head types of the works on repair of engines performed directly on the car are described. If the engine was removed from the car and understood, then some preliminary operations on dismantling can be excluded.

Engines 1,4 and 1,6 of l belong to the GA series, installed on the Nissan cars. Engines 16-valvate with the top arrangement of valves, four rowed cylinders and two cam-shafts. The engine settles down across a car axis, in its forward part. Transmission is established on the left side of the engine.

The crankshaft is 5-basic. The axial side play of the crankshaft is regulated by selection of the persistent half rings established on the top half of the average radical bearing.

Conrod bearings consist of two inserts inserted into a rod and into a rod cover. Rods are connected to pistons by means of fingers which freely move in a head of a rod and fixed by spring lock rings. Pistons are cast from aluminum alloy, on pistons three rings – two compression and one oil scraper are provided.

Inlet and final valves are closed under the influence of spiral springs and move in the directing plugs pressed in a head of the block of cylinders together with saddles of valves. At the increased wear of a saddle and the plug it is possible to vypressovat and replace new.

Cam-shafts have the drive from a chain and operate 16 valves through pushers of badeyny type. Pushers are established under cam-shafts. Gaps in valves are regulated by selection of special washers for thickness. The lower support of necks of cam-shafts are the beds chiseled in inflows of a head of cylinders.

Lubricant of the engine is carried out from the oil pump with the drive from a crankshaft sock. Oil passes through an oil receiver with the filter of rough cleaning, further via the filter of thin cleaning screwed in the block of cylinders of the engine and moves to lubricant canals in the block of cylinders and a case of the crankshaft from which it goes to radical bearings of the crankshaft and to basic necks of a cam-shaft. Conrod bearings are greased under pressure through openings in the crankshaft. Cam-shaft cams, cores of valves and other details of the engine are greased with spraying.
