ABSTRACT:
Heat plugs made of durable, heat resistant material are useful for protecting aluminum pistons from the jet flame of burning fuel emitted from the precombustion chamber of some compression ignition engines. However, when slower burning fuel such as vegetable oil is burned, unburned fuel is sometimes deflected by the heat plug against the adjacent cylinder bore where it dilutes the lubricating oil and causes high wear to that portion of the bore and to the piston rings. The subject heat plug (26) is provided with a barrier (37) which prevents unburned fuel from being deflected against a portion of the cylinder bore (12) nearest the heat plug. Thus, that unburned fuel remains in the burning gaseous mixture in the combustion chamber and is burned during the combustion process within the combustion chamber.
