Abstract
In the control device, a relationship of a throttle-upstream pressure with respect to an exhaust-gas amount is used in a state where a supercharge pressure becomes the lowest by a WG-instruction value with respect to a WGV-control componentfor driving a WGVprovided at a bypass passagebypassing a turbocharger, and a relationship of a throttle-upstream pressure with respect to an aperture of a throttle valve, a rotational speed of an engine, and an intake-manifold pressure is used, and any of the throttle-upstream pressures, whichever is higher, being calculated in accordance with each of the relationship, is defined as a throttle-upstream-estimation value, whereby the throttle-upstream pressure is estimated by a cheap means with high accuracy so as to control the engine.
