Abstract
Methods and systems are provided for the estimation of an aircharge into a cylinder used to adjust an engine operating parameter, based on a manifold pressure signal stored in a buffer. In one example, a method may include sampling an intake manifold pressure sensor signal at even increments of time, stamping it with its corresponding crank angle and storing it in a buffer. The closest stored signal to the intake valve closing of a cylinder may be used to calculate its aircharge.
