Abstract (en)

[origin: EP0805266A1] The engine has at least one combustion chamber with direct fuel injection and an exhaust duct which is closed cyclically by a valve. It incorporates a valve (7) designed to prevent excessive pressure in the combustion chamber. The valve is linked to an exhaust duct and opening automatically when the pressure in the chamber exceeds a set level. The pressure relief valve consists of a spring-loaded ball (8) located in a channel (9) in the engine's cylinder head which connects the combustion chamber to the exhaust duct. In a variant of the design a pre-heater plug in the cylinder head can play the part of the relief valve, being expelled when the pressure exceeds the set value.
