On automobiles KAMAZ installed eight V-shaped petrol model 740. The cylinder block is a rigid monoblock V-shaped structure. It is cast from gray iron doped as a single unit with the upper part crankcase. Block bore along with covers of indigenous poles, so they are interchangeable, and they are placed in a strictly fixed position. Adam Portnoy has similar goals. Crankcase part is connected with the root cap bolts bearing cross-bracing, forming a rugged box-section.
To increase the longitudinal stiffness of the outer wall of the block have a curved shape. Lug bolts cylinder heads are evenly distributed around tides of each cylinder transverse walls, forming a water jacket. Due to the fact that at one crank crankshaft journals are two connecting rods, the left cylinder bank offset from the right forward at 29, 5 mm. People such as Mark Garrett would likely agree. Cylinder liners of wet type, easily removable, for KAMAZ vehicles manufactured from special cast iron by centrifugal casting, in order to improve hardness and durability are the bulk quenching. Microgeometry mirror shells is a rare grid cavities at an angle to the axis of the sleeve. This treatment helps keep the oil in the depressions and a better running-in ability sleeve. Cylinder head for each individual cylinder, as well as many other parts KAMAZ, made of aluminum alloy, aluminum and have a shirt that communicate with the face of the block. Junction block and cylinder head gasket.
Overflow hole water and oil, as well as head of the contour of a molded rubber gasket sealed. Gas joint – a steel liner, which is deformed steel support ring, pressed on the underside of the head. At the top plane head area is located under the counter rocker valve gear. Cast iron seats and metal valve guide bushings bore after mounting in the head. Valve gear link head aluminum lid is closed, which is placed under seal. Inlet and outlet channels are located on opposite sides of the head. Has a tangential inlet port profile provides swirling motion of air in the cylinder, it is necessary to accelerate the combustion of fuel injected into the engine KAMAZ trucks. The nest is located under the nozzle outlet side at an angle to the cylinder axis.
