Auxiliary combustion chamber for a stratified charge internal combustion engine

Patent ·
OSTI ID:5315397
An auxiliary combustion chamber for a stratified charge internal combustion engine is formed by an insert secured in a bore of the cylinder head. The insert is in the form of a tubular shell having openings for ignition means, fuel supply means, and having a passage communicating with the main combustion chamber. The tubular shell has a relatively massive construction in the region of the passage and is relatively thin walled in the remaining regions to provide the capability for fast warm-up of the auxiliary combustion chamber and to prevent overheating of the chamber in the region of the passage.
