Embodiment Construction

[0074] The engine combusts a mixture of air and fuel within cylinders to produce drive torque. The throttle valve regulates airflow into the engine. Fuel is injected by fuel injectors. Spark plugs create a spark within the cylinder to initiate combustion. The spark plug may be omitted in some types of engines, such as diesel engines. The intake and exhaust valves of the cylinders can be controlled to regulate the flow into and out of the cylinders.

[0075] The fuel injectors receive fuel from the fuel rail. In some examples, the high pressure fuel pump receives fuel from the low pressure fuel pump and pressurizes the fuel within the fuel rail. The low pressure fuel pump draws fuel from the fuel tank and supplies fuel to the high pressure fuel pump. Fuel injectors inject fuel directly into the cylinders of the engine. Power is applied to the fuel injector to open the fuel injector (eg, the fuel injector's pivot or anchor).

[0076] One or more of the fuel injectors may ...

Abstract

Disclosed is early detection of fuel injectors with manufacturing issues. A diagnostic system for a fuel injector includes a plurality of sensors to sense vehicle data. A controller includes a fuel injector diagnostic module configured to receive the vehicle data during operation of the vehicle and to selectively identify at least one of a fuel injector with a stuck armature and a fuel injector with pintle fatigue.

Description

[0001] introduction [0002] The information provided in this section is for the purpose of generally presenting the context of the disclosure. To the extent described in this section, the work of the presently named inventors, and aspects of the description that may not constitute prior art at the time of filing, are neither expressly nor impliedly admitted to be prior art to the present disclosure. technical field [0003] The present disclosure relates to internal combustion engines, and more particularly to fuel injector control systems and methods for the engines. Background technique [0004] Air is drawn into the engine through the intake manifold. The throttle and / or engine valve timing controls airflow into the engine. Air mixes with fuel from one or more fuel injectors to form an air / fuel mixture. The air / fuel mixture is combusted in one or more cylinders of the engine. Combustion of the air / fuel mixture may be initiated by a spark provided, for example, by a s...
