Methods and systems are provided for aging a new plastic fuel tank in a vehicle. In one example, during a plug-in event to recharge a battery of the vehicle, the fuel tank is isolated and the fuel pump is actuated to agitate fuel within the tank and increase fuel vapors until the plastic fuel tank becomes aged to a predetermined degree by fuel vapors generated therein. In this manner, the fuel tank is aged more rapidly, resulting in more accurate fuel level readings and less noise and vibration.

Methods and systems for aging a fuel tank in a plug-in hybrid electric vehicle

Methods and systems are provided for draining water separated from diesel fuel into an EGR system. In response to the water volume in the fuel system and EGR flow at pre-determined levels, water may be introduced into the EGR system. EGR flow may also be controlled in response to introducing water into the EGR system and engine operating conditions.

Diesel engine water in fuel separator and reservoir automatic drain system and control strategy

A fuel system for an engine is provided herein. According to one embodiment, the fuel system includes a fuel supply coupled to a low pressure fuel pump, the low pressure fuel pump coupled to a high pressure fuel pump to provide fuel to a fuel rail. Further, the fuel system includes a plurality of injectors coupled to the fuel rail to provide fuel to a plurality of engine cylinders. Further still, the fuel system includes a first fuel return line coupling the fuel rail to the fuel supply and a thermal recirculation valve, the thermal recirculation valve further coupled to a low pressure pump intake line; a second fuel return line coupling the high pressure fuel pump to the first fuel return line; and a third fuel return line coupling the plurality of injectors to a high pressure pump intake line.

Multi-staged fuel return system

A method, comprising generating a water-in-fuel indication responsive to a water-in-fuel content increasing more than a threshold amount within a threshold time of a refueling event is presented.

Method for detecting water-in-fuel after refueling event

A method is described for managing vapors generated from an ammonia-containing reductant delivery system. The method may include generating ammonia vapors in a first storage device and storing said generated ammonia vapors in a second storage device. Further, the method may include purging the stored vapors from the second storage device to upstream of a combustion chamber of the engine during a first condition and downstream of the combustion chamber during a second condition.

Ammonia vapor management system and method

A system of alternate hose line bundling allows for exclusion of a higher pressure hose line from fasteners directly attached to a vehicle body. Alternatively to mounting to the vehicle body, the higher pressure hose line is coupled to a lower pressure hose line via fasteners which lack mounting features. Eliminating attachment of higher pressure hose lines to the vehicle body reduces noise, vibration, and harshness (NVH) experienced by passengers in the vehicle.

Automotive line bundling system

A fuel system for a diesel engine has both a low pressure pump, which extracts fuel from the fuel tank, and a high pressure pump, which is fed by the low pressure pump and supplies fuel to fuel injectors. The fuel injectors supply fuel to the engine cylinders, with a small portion of fuel routed back into the fuel system. According to an embodiment of the present disclosure, the injector return fuel is routed into a low pressure fuel line between the low and high pressure fuel pumps, with return fuel from the fuel rails returned through a fuel cooler to the fuel tank. The low pressure fuel line has a filter disposed therein and the injector return fuel is returned to the low pressure fuel line upstream of the filter.
