Abstract
Abstract A self-contained device for preheating or maintaining a predetermined heat in an internal combustion engine. The device includes a so-called infrared burner that is adapted to be positioned in heat exchanging relationship with a portion of the engine, a fuel source for the burner, and an ignition source for igniting the burner. The ignition source is adapted to be suitably powered, for example, by the battery of the associated engine.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
126 words
A self-contained heating system for a liquid cooled internal combustion engine having a cooling jacket with an opening formed in an outer wall thereof, said heating system comprising a mounting portion having a flange adapted to engage the cooling jacket outer wall around the opening and a cup-shaped portion extending into the cooling jacket and having a substantial heat radiating area exposed to the coolant therein, a flameless infra-red burner supported by said mounting portion and extending into the interior of said cup-shaped portion for establishing a heat exchange relationship with the coolant, a fuel source for supplying fuel to said flameless infra-red burner, and an electrical ignition system for said burner fired by the battery of the associated engine independent of the vehicle ignition system.
