Abstract: A fuel injection system for an internal combustion engine, comprising: at least one fuel electroinjector; and one electronic control unit designed to supply the fuel electroinjector, in a fuel injection phase in an engine cylinder, with at least a first electrical command to perform a pilot fuel injection, and a second electrical command to perform a main fuel injection. The first and second electrical commands are separated in time by an electrical dwell time such that the main fuel injection starts without interruption with respect to the pilot fuel injection. The electrical dwell time between the first and second electrical commands belongs to an electrical dwell time range in which the total fuel amount injected in the pilot and main fuel injections in a fuel injection phase in an engine cylinder is substantially constant.

Abstract: In a vehicle provided with a power propulsion system of the mild-hybrid type, a BAS unit —including an electric machine connected through a belt transmission to the shaft of an internal combustion engine—is exploited as the only propulsion engine of the vehicle in given operating conditions. The internal combustion engine is provided with a system for variable actuation of the intake valves which is controlled to reduce the pumping losses of the internal combustion engine in the phase in which such engine is in cut-off condition and it is driven by the aforementioned BAS unit. It is also provided for that the system for variable actuation of the intake valves be controlled to temporarily increase the pumping losses of the internal combustion engine in a phase in which it is required to accelerate the switching off of the engine.

Abstract: In an internal-combustion engine provided with a system for variable actuation of the intake valves of the cylinders, some of said cylinders are deactivated in given conditions of operation of the engine by interrupting the supply of fuel. During de-activation, the cycle of opening and closing of the intake valves and exhaust valves of the deactivated cylinders is maintained. The intake valves of each deactivated cylinder are opened when the exhaust valves of the same cylinders are also open. The inactive cylinders are used as reciprocating volumetric pumps for recirculation of exhaust gases from the exhaust manifold of the engine up to the intake manifold. The recirculated gases are cooled in the intake manifold by the air introduced into the latter and can consequently be fed in a larger mass to the active cylinders, which enables a better global efficiency of the engine to be obtained.
