Abstract
A system according to the principles of the present disclosure includes a misfire detection module and a fuel control module. The misfire detection module detects misfire in a cylinder of an engine. The fuel control module controls a first fuel system to deliver a first fuel to the cylinder and controls a second fuel system to deliver a second fuel to the cylinder. The first fuel and the second fuel are different types of fuel. The fuel control module selectively switches from delivering the first fuel to the cylinder to delivering the second fuel to the cylinder when misfire is detected in the cylinder.
