Engine: Motor Plants and Auxiliary Boilers

1. A Ignition is achieved by the heat of compression created by compressing the air/fuel mixture within the cylinder into a relatively small volume.
2. B Ignition is achieved by intense heat by passing electric current through the element of a specially designed glow plug.
3. C Ignition is achieved by a high voltage electric spark induced across the gap of a specially designed spark plug.
4. D Ignition is achieved by the heat of compression created by compressing intake/charge air within the cylinder into a relatively small volume.
