Embodiment Construction

[0014] This instruction is concerned with operating a hybrid vehicle including the engine and electric machine. The electric machine is operable to provide electrical power to an external electrical power consuming device. vehicles may include figure 1 Type of engine shown. Engines can be included in such figure 2 in the drive train shown. The vehicle drivetrain can be image 3 sequence to operate. The vehicle drivetrain can be Figure 4 method to operate. Engines can include such as Figure 5 Regions of carbon accumulation, carbon removal, and carbon neutralization operations shown.

[0015] refer to figure 1 , an internal combustion engine 10 (comprising a plurality of cylinders, figure 1 One of the cylinders shown in ) is controlled by the electronic engine controller 12 . Controller 12 from figure 1 and figure 2 Various sensors are shown receiving signals. Based on the received signals and the instructions stored in the memory of the controller 12, the cont...

Abstract

Methods and system for reducing a possibility of spark plug fouling. Systems and methods for operating a vehicle that includes an engine and an electric machine are described. In one example, operation of the engine may be adjusted to compensate for conditions when carbon deposits may build on one or more engine spark plugs. The engine adjustments may help to remove carbon deposits from the engine's spark plugs.

Description

technical field [0001] The present description relates to methods and systems for a vehicle comprising an electric machine for supplying electric power to an external electric power consumer. Background technique [0002] A vehicle may include an electric machine that provides propulsion to the hybrid vehicle. The electric machine can also supply alternating current to external electric power consumers from time to time. Additionally, in some examples, the electric motors may not provide propulsion for the vehicle. In one example, a hybrid vehicle may be parked at a construction site, and an engine of the hybrid vehicle may rotate an armature of an electric machine such that the electric machine may supply electrical power to an electrical power consumer external or off-board to the hybrid vehicle. The engine of the hybrid vehicle can be operated at various speeds and loads to satisfy the electric power consumption of the electric power consuming devices. The engine can a...
