For diesel engines, such as those used for main propulsion and auxiliary power on offshore supply vessels, while running at speed, how is the ignition of fuel within the cylinder achieved?

Question

Accepted Answer

Ignition is achieved by the heat of compression created by compressing intake/charge air within the cylinder into a relatively small volume.

Answer

Ignition is achieved by a high voltage electric spark induced across the gap of a specially designed spark plug.

Answer

Ignition is achieved by the heat of compression created by compressing the air/fuel mixture within the cylinder into a relatively small volume.

Answer

Ignition is achieved by intense heat by passing electric current through the element of a specially designed glow plug.
