NCI Monobloc Piston
High strength and low thermal expansion of the material used allow the manufacturing of thin-wall pistons and the introduction of low running clearances. Monobloc pistons in diameters from 170 to 350 mm diameters represent an economically attractive alternative to composite pistons in account of their simple design (no connecting elements, integrated cooling spaces) and their proven reliability with heavy fuel operation.
One piece aluminum pistons made of KS 1275 eutectic AlSi alloy, are employed in diameters ranging from 160 to approximately 450 mm. Pistons with diameters exceeding 200 mm are manufactured employing directionally chilled fine grain castings, with cast-in ring carriers of austenitic grey iron and cooling coils.
The KS Kolbenschmidt design for an articulated large bore piston is a three piece articulated piston or a composite articulated piston. The forged steel crown is bolted together with a cast pin boss. The skirt is made out of forged aluminum and it is connected to the pin boss by the piston pin. The advantages of this design are basically the low weight by achieving high performance data and it is possible to achieve a relatively low compression height.
