摘要： Various methods and systems are provided for skip-firing an engine. As one embodiment, a method for an engine includes firing all cylinders of the engine and not altering the closing timing of the intake valves when fueling demands are greater than a threshold. The method further includes skip-firing the engine when fueling demands are less than a threshold, and holding open the intake valves of skipped cylinders for a greater duration than intake valves of firing cylinders.

摘要： Various methods and systems are provided for a pressure relief valve (150) of a fuel system. In one example, a valve (150) includes a first chamber (208) in fluid communication with a first fuel line (154), a second chamber (210) in fluid communication with a second fuel line (222) and in fluid communication with a fuel storage tank, a piston (202) separating the first chamber (208) from the second chamber, and a needle (206) coupled to the piston (202) and controlling a flow passage between the second fuel line (222) and the second chamber (210), where the piston (202) and needle (206) are sized such that a force applied on the piston (202) by the first chamber (208) parallel to an axis of movement of the piston (202) maintains the needle (206) in a closed position when the first fuel line (154) flows fuel at a first pressure and the second fuel line (222) flows fuel at a second pressure, the second pressure greater than the first pressure.

摘要： A system detects a parameter and generates a first trip plan to automatically control the vehicle according to the first trip plan. A controller is connected to a sensor and configured to receive the parameter. The controller is configured to generate a new trip plan or modify the first trip plan into a modified trip plan based on at least one of a cumulative damage or an end of life of a propulsion subsystem component. The new trip plan or the modified trip plan is configured, during operation of the vehicle according to the new trip plan or the modified trip plan, for at least one of an adjustment in velocity or avoiding one or more operating conditions of the vehicle, relative to the first trip plan.
