“…The physical design of the multisensing fuel injector was discussed in previous publications [13,14], Current signals, obtained from the MSFI and the spark plug, are measured in terms of voltage drop across a re sistor. The pressure trans ducer model number is 6118BCD25.…”

“…Furthermore, the complexity of the fuel injection system is another challenge to the reliability of GDI engine performance. In addition, the signal produced by the injector and associated electric circuit can be used for the diagnosis of malfunctions that might occur in the injection process and as a feedback input to the engine's engine control module (ECU) [13]. This paper explains the use of the fuel injector as a multi sensing device for application in GDI engines.…”

Multisensing Fuel Injector in Turbocharged Gasoline Direct Injection EnginesWith the increasingly stringent emissions and fuel economy standards, there is a need to develop new advanced in-cylinder sensing techniques to optimize the operation of the in ternal combustion engine. In addition, reducing the number of on-board sensors needed for proper engine monitoring over the lifetime of the vehicle would reduce the cost and complexity of the electronic system. This paper presents a new technique to enable one engine component, the fuel injector, to perform multiple sensing tasks in addition to its piimaiy task of delivering the fuel into the cylinder. The injector is instrumented within an electric circuit to produce a signal indicative of some injection and combustion pa rameters in electronically controlled spark ignition direct injection (SIDI) engines. The output o f the multisensing fuel injector (MSFI) system can be used as a feedback signal to the engine control unit (ECU) for injection timing control and diagnosis of the injection and combustion processes. A comparison between sensing capabilities o f the multisensing fuel injector and the spark plug-ion sensor under different engine operatingconditions is also included in this study. In addition, the combined use of the ion current signals produced by the MSFI and the spark plug for combustion sensing and control is demonstrated.
