2. Glow plug - Wikipedia

   en.wikipedia.org/wiki/Glow_plug

   In a diesel engine, a glow plug (also spelled glowplug) is a heating device used to aid starting of the engine in cold weather. This device is a pencil-shaped piece of metal with an electric heating element at the tip. A glowplug system consists of either a single glowplug in the inlet manifold, or one glowplug per cylinder. In older systems ...

3. Cold start (automotive) - Wikipedia

   en.wikipedia.org/wiki/Cold_start_(automotive)

   Starting fluid, a volatile liquid, is sometimes sprayed into the combustion chamber of an engine to assist the starting procedure. Diesel engines make use of glow plugs to heat the combustion chamber prior to ignition, improving the conditions inside the engine, while certain manufacturers have incorporated a block heater, which heats the ...

4. Starting fluid - Wikipedia

   en.wikipedia.org/wiki/Starting_fluid

   Starting fluid is sprayed into the engine intake near the air filter, or into the carburetor bore or a spark plug hole of an engine to get added fuel to the combustion cylinder quickly. Using starting fluid to get the engine running faster avoids wear to starters and fatigue to one's arm with pull start engines, especially on rarely used machines.

5. Flame-start system - Wikipedia

   en.wikipedia.org/wiki/Flame-start_system

   The flame-start system is a cold start aid for starting diesel engines at low ambient temperatures. It reduces the white smoke emission after the engine is started. In addition, it reduces the strain on the starter motor and batteries by shortening the start-up time. [1]

6. Indirect injection - Wikipedia

   en.wikipedia.org/wiki/Indirect_injection

   The addition of a prechamber increases heat loss to the cooling system and thereby lowers engine efficiency. The engine requires glow plugs for starting. In an indirect injection system the air moves fast, mixing the fuel and air. This simplifies engine (piston crown, head, valves, injector, prechamber, etc.) design and allows the use of less ...

7. Ignition system - Wikipedia

   en.wikipedia.org/wiki/Ignition_system

   A variation coil-on-plug ignition has each coil handle two plugs, on cylinders which are 360 degrees out of phase (and therefore reach top dead center (TDC) at the same time); in the four-cycle engine this means that one plug will be sparking during the end of the exhaust stroke while the other fires at the usual time, a so-called "wasted spark ...
