Abstract
A fuel control system for an engine utilizing direct fuel injection including a smoke sensor for measuring the level of smoke in the engine exhaust. A control module, in response to the output signal from the smoke sensor, regulates the timing and delivery of fuel to the engine, the delivery of air to the engine, the amount of exhaust gases that are recirculated to the engine, the turbo boost pressure and performs on-board diagnostics.
