Balancing Of Inline and Radial Engines:

The internal combustion engine of multi-cylinder kinds is in common use. Each of cylinders carries piston that reciprocates and is responsible for making disturbing force on foundation. Each of the cylinders shall have primary and secondary disturbing forces that have to be balanced. The cylinders are arranged in a line along 2, 3 or more. Two cylinders or banks of four or six cylinders might be arranged along centre lines at angle resulting in a V-formation. The cylinders might be arranged on a circle along central lines along radii meeting at centre on a single crank pin giving configuration of a radial engine. In W-engine three cylinders or three rows of cylinder are arranged along their centre lines at some acute angle.

In each of the case the cylinders do not fire at the similar time but two or more might fire at a time. However, their firing order shall not influenced unbalanced disturbing force or balancing procedure which are just affected by weight or mass of reciprocating and rotating parts.

Objectives

We shall consider balancing -primary and secondary both - of various engines and while you have gone through this unit you would learn following

  • how to measure balanced state in a multi-cylinder engine,
  • how to balance multi-cylinder engine for primary & secondary disturbing forces, and
  • how to utilize balancing machines.
