2.3.1.5. Block of cylinders
The block of cylinders has a corner of disorder 60 ° and the mutual longitudinal shift of ranks of cylinders of 36,6 mm (1,44 inches), distances between axes of cylinders make 105,5 mm (4,15 inches) that allows to provide its compactness. The block of cylinders is manufactured of light aluminum alloy. Thin-walled pig-iron sleeves of cylinders are established with a tightness to guarantee additional reliability. Sleeves of cylinders too thin-walled, thus, boring is not possible. For ensuring compactness of the engine the camera of the pump of cooling liquid and the input channel of the pump are located in disorder of the block of cylinders. Inflows of fastening of sensors of a detonation are located in two places in disorder of the block of cylinders. Covers of bearings of a bent shaft fasten four bolts with the inhaling moment in a plasticity zone for each radical neck of a bent shaft. Besides, each cover is pulled together with bolts in the cross direction for increase in reliability of its fastening.
Fig. 2.182. Block of cylinders of the engine 1MZ-FE: 1 – camera of the pump of cooling liquid; 2 – inflows of sensors of a detonation; 3 – cover of the bearing of a bent shaft; 4 – sealing washer; 5 – bolts with the inhaling moment in a plasticity zone
