Abstract
An apparatus having a device for measuring speed by counting pulses and a device for measuring pressure by counting pulses wherein a first memory stores advance correction coefficients and a second memory stores a value with respect to full-load advance. An advance counter is connected to the outputs of the second memory and to the highest-weight output of the pressure counter by way of a series connection of a binary rate multiplier, a divider which divides by M and a switching device.
