General Motors has developed a quick-start system for its passenger-car diesel engines which reduces glow plug heatup time by an order of magnitude. The new system heats the glow plugs to operating temperature in 6.5 seconds, compared to 60 seconds for the system it replaces. Although peak power input to the system from the battery source is twice as high as that of the older system, total energy drained from the battery is reduced. Prechamber-injection diesel engines require heated glow plugs extending into the chambers to aid starting when cold. The preheat period of the glow plugs must precede engine cranking by enough time for the plugs to be heated above the flash temperature of the diesel fuel.
