1.	Which if the following is defined as the distance between the axis of the piston pin and top of the piston crown?(a) Clearance volume(b) Swept volume(c) Compression height(d) Detonation lengthI have been asked this question by my school principal while I was bunking the class.Question is from Engine Components topic in division Basic Engine Components of Automotive Engine Design
Answer» Right option is (c) Compression height Best explanation: The distance between the axis of the PISTON PIN and the top of the piston crown is called compression height and determines the compression RATIO for a given engine. THUS for the same engine, a piston with lesser compression height would give a lesser compression ratio and vice VERSA.
