  • Spark ignition engine having combustion chamber provided with vent valve
    Patent number: 3993037
    Abstract: A vent valve allows a combustion chamber arranged to burn a swirling lean mixture to communicate with either an intake manifold or exhaust manifold through a vent port by-passing the intake or exhaust valve, for a short period just before ignition to discharge a fraction of the mixture from the combustion chamber. The discharge weakens the turburent flow of the mixture and results in a decreased combustion temperature, which is advantageous for suppression of NOx formation and prevention of combustion noise generation.
