摘要： An engine system is disclosed. The engine system may have an engine including at least one cylinder. The engine system may also have a first source configured to supply fuel for combustion in the engine and a second source configured to supply an ignition promoter material for combustion in the engine. The engine system may have a droplet injector configured to generate at least one droplet of the ignition promoter material, apply an amount of charge on the at least one droplet, and deliver the at least one droplet to the at least one cylinder. The engine system may also have a controller. The controller may be configured to determine an engine parameter, and to determine the amount of charge based on the engine parameter. In addition, the controller may be configured to adjust the droplet injector to apply the determined amount of charge to the at least one droplet.

The controller may be configured to determine an engine parameter. The controller may also be configured to determine a number of the droplets based on the engine parameter. Further, the controller may be configured to determine droplet sizes of the droplets based on the engine parameter. In addition, the controller may be configured to adjust the droplet generator to generate the number of the droplets having the droplet sizes.

摘要： A system for reforming a fuel may include a first sensor configured to measure an operating parameter of an engine. The operating parameter may correlate to a NOx emission level of the engine. The system may also include a controller in communication with the sensor and a reformer. The controller may be configured to determine a target NOx emission level for the engine. The controller may be also configured to determine a target value of the operating parameter corresponding to the target NOx emission level. The controller may be further configured to control the reformer to reform at least a portion of the fuel based on a difference between the measured value and the target value of the operating parameter.
