Abstract: An injector driver module applies power to a fuel injector of an engine for a fuel injection event. A voltage measuring module measures first and second voltages at first and second electrical connectors of the fuel injector. A parameter determination module determines a maximum value based on a first difference between the first and second voltages, determines a minimum value based on the first difference between the first and second voltages, and determines a second difference between the maximum and minimum values. A diagnostic module, based on the second difference between the maximum and minimum values, indicates whether the fuel injector injected fuel in response to the application of power.

Abstract: A system according to the principles of the present disclosure includes an ignition timing determination module, an injection timing determination module, a spark control module, and a fuel control module. The ignition timing determination module determines a first crank angle. The injection timing determination module selectively determines a second crank angle based on the first crank angle. The spark control module controls a spark plug to generate spark in a cylinder of an engine at the first crank angle. The fuel control module controls a fuel injector to deliver fuel to the cylinder at the second crank angle.

Abstract: A method for controlling variable oil pressure to a piston squirter based on piston temperature according to an exemplary embodiment includes a temperature estimation module and an oil pump pressure control module. The temperature estimation module estimates a piston temperature associated with a cylinder based on engine operating conditions. The oil pump pressure control module controls the oil pressure level delivered to at least one of piston squirter associated with the cylinder to selectively spray oil on the piston based on temperature estimations.

Abstract: A fuel control system according to the principles of the present disclosure includes a voltage measuring module, a first difference module, a second difference module, a third difference module, and an injector driver module. The voltage measuring module measures first and second voltages at first and second electrical connectors of a fuel injector of an engine. The first difference module determines a first difference based on a difference between the first and second voltages. The second difference module determines a second difference between (i) the first difference and (ii) a previous value of the first difference. The third difference module determines a third difference between (i) the second difference and (ii) a previous value of the second difference. The injector driver module selectively applies power to the fuel injector based on the third difference.
