    Qianfan Xin, in Diesel Engine System Design, 2013. 11.5.1 Piston slap noise. There are three possible types of piston noise, namely piston rattling noise (i.e., the top land contacts the cylinder bore), piston pin ticking noise (i.e., pin-bearing impact), and piston slap noise (i.e., the skirt contacts the bore). The first two types of noise can be avoided or eliminated by proper design.
