摘要： An ignition system for an engine of a vehicle, comprising: a spark plug which includes: a central electrode electrically connected to an ignition coil, and a ground electrode, where the spark plug ignites a mixture of fuel and air in a normal mode of the engine; a high speed pulser to ignite the mixture of fuel and air in a lean-burn mode of the engine; a pulser controller to control the high speed pulser to ignite the mixture of fuel and air in the lean-burn mode of the engine; an engine control unit (ECU) that determines the normal and lean-burn modes based on an engine speed and an engine load, and controls the pulser controller and an ignition of the spark plug based on a determined mode among the normal mode and the lean-burn mode.

摘要： Methods and systems are described for a hybrid vehicle with a passive prechamber combustion engine. The system includes a passive prechamber combustion engine, an electric motor, and a controller communicatively coupled to the combustion engine and the electric motor. The combustion engine is configured to operate at engine loads satisfying a load threshold. The controller is configured to determine whether an engine load falls below the load threshold. The controller is configured to select the electric motor to propel the vehicle. The controller is configured to determine whether the engine load satisfies the load threshold. The controller is configured to select the combustion engine to propel the vehicle for providing efficient fuel consumption associated with prechamber ignition in response to determining that the engine load satisfies the load threshold.
