  • Fuel burner for heating internal combustion engine intake air
    Patent number: 4368715
    Abstract: A burner assembly (18) for heating the intake air of an internal combustion engine (2) including a burner housing (32) containing a fuel passage (52, 66, 70, 72) and a glow plug (87) for heating the burner housing (32) upon start up of the burner to melt fuel wax deposits in the fuel passage (52, 66, 70, 72). The glow plug (87) includes a metal sheath (88) designed normally to contact air when energized at a rated level. The burner housing (32) includes a cavity (86) shaped to receive the glow plug (87) with a minimal clearance (a) large enough to prevent interference during assembly but small enough to allow metal-to-metal heat transfer into the housing (32) when the glow plug (87) is energized at twice its rated level.
