ABSTRACT:
An insulated pre-combustion chamber of an internal combustion engine in which a piston is disposed in a cylinder for reciprocal movement relative to the cylinder. A cylinder head is provided over the cylinder and piston to form a main combustion chamber and the pre-combustion chamber is located in the cylinder head above the main combustion chamber. The pre-combustion chamber includes a pair of rigidly interconnected housing members with transfer passages formed in the lower housing member for connecting the pre-combustion chamber with the main combustion chamber. At least one insulation member is located between the upper and lower housing members and the cylinder head for reducing the heat loss from the pre-combustion chamber.
