Question

Which of the following describes the displacement or swept volume?

(a) Vs=\(\frac{Π}{4}\)∗d^2l

(b) Vs=\(\frac{Π}{16}\)∗d^2l

(c) Vs=\(\frac{Π}{32}\)∗d^2l

(d) Vs=\(\frac{Π}{4}\)∗d^3l

This question was posed to me during an interview for a job.

Asked question is from I.C Engine topic in section Internal Combustion Engine of Farm Machinery

Answer 1

Correct choice is (a) Vs=\(\frac{Π}{4}\)∗d^2l

The best explanation: Vs=\(\frac{Π}{4}\)∗d^2l describes Swept volume or the displacement. Volume is swept when the piston moves between top dead centre and bottom dead centre during the movement of piston.
