Cork
Fabric
Asbestos
Leather
White deposits on the face of a spark plug suggest that
Spark plug is of too high rating
Mixture is too rich
The engine is excessively advanced
Too large a gap between the electrodes
A hot plug has
Long insulation
Long threaded portion
Long path for heat dissipation

Gap between electrodes in mm
Electrode diameter in cm
Width of tip in mm
Pitch of plug thread
Description:

A series of tests is launched to offer the students of Mechanical Engineering to help them in checking their level of knowledge. These tests will contribute in building the aptitude of the students in various topics of Mechanical engineering. Majority of the questions are from IC engines and Automobile Engineering.
