  • Patent number: 4815426
    Abstract: An engine heater for automotive vehicles which adapts a common propane torch to accomplish the heating. The prime features of the invention are its simplicity, compactness, economy, ease of being carried in the vehicle, and its not needing any installation in or modification to the vehicle in order to be used. Heat is safely applied over a relatively large area of the bottom of a vehicle's engine oil pan and then the heated oil pan and oil will cause the critical interior portions of the engine to be warmed; thus, greatly enhancing the engine's ability to start and run in very cold weather. The device also includes means of preventing strong wind from either blowing out the flame or carrying most of the heated air/exhaust gas discharge away from the bottom of the engine.
