Abstract

In an internal combustion engine group of the type comprising a cooling fan 15 positioned on the engine crankshaft 13 together with a flywheel 16, said flywheel is structurally combined with a rotor 18 of a generator, a related stator 20 being constrained to a case 17 encasing said fan and conveying said cooling air towards an exchanger 22. <IMAGE>

Description

SPECIFICATION Internal combustion engine group with electric generator The present invention relates to an internal combustion engine group on whose flywheel a rotor is positioned, which, together with a stator coupled therewith, constitutes and electric generator incorporated inside the same engine group.
It is known to use, e.g. in emergency electrogenous groups, and internal combustion engine, linked either by means of related couplings and supports, or on an extension of the driving crankshaft, with an electric generator.
Such a type of engine-generator assembly has however a quite large overall dimension and also a not negligible weight.
Purpose of the present invention is to provide a generator-engine assembly particular compact and of reduced weight, so that it can be used also within limited rooms, and can be easily transported to the place where its use is required.
Further purpose of the invention is that the reduced overall size and weight involve also a decrease in cost of the assembly, and render it simple from the constructional and maintenance point of view.
These and further purposes according to the present invention are accomplished by providing an internal combustion engine group of the type comprising a cooling fan installed on the crankshaft of the engine together with a flywheel, characterized in that to said flywheel a rotor of a generator is structurally combined a related stator being constrained to a case encasing said fan and conveying said cooling air towards an exchanger.
The structural and functional features and the advantages of a group according to the present invention will be better understood from the following exemplifying and not limitative disclosure, referred to the attached schematic drawing, wherein a partial sectional view of an engine-alternator assembly is shown.
As shown in an internal combustion engine according to the present invention, and generally indicated with 11, a cylinder block 12 supports a crankshaft 13 operatively linked to a piston 14.
On said crankshaft 13 a blade fan 15 and a wheel 16, provided with spokes 24 of extremely reduced size, are constrained, being both encased with a case 17 fastened on to the cylinder block 12.
On the opposite side relatively to the fan 15 of the flywheel 16 an annular rotor 18 and a pulley 19, essentially intended for start purposes, are placed. Externally relatively to the rotor 18 and coaxially thereto a related stator 20 is positioned, constituting the generator, constrained to the case 17, which in an upper portion of its own 21 has the function of conveying the cooling air delivered towards an exchanger 22 installed in the upper part of the assembly. Said air indeed enters the grouppassing through the central port 23 provided in the pulley 19, passes into the inner space of the rotor 18 according to the direction of the arrows 25, and therefrom between the spokes of the flywheel 16, arriving at the fan 15. The same fan 15 delivers the air throughout the case 17 and in particular towards its upper portion 21 (see arrow 26), where the exchanger 22 is placed.
The rotor 18stator 20 subassembly is thus particularly compact, in that it is contained within the same overall dimension of the engine group, and does not extend to a noticeable extent, as it usually occurs on the free portion of the crankshaft. The rotor 18 moreover constitutes a rotating mass acting, among others, as a flywheel and it is for this reason that the very flywheel 16 is of very reduced size. It is just for this reason moreover that the weight also of the internal combustion engine-generator assembly is much lower than that of the known groups.
It should not be neglected the notable simplifying obtained by means of an assembly according to the present invention, wherein couplings, intermediate supports and additional protections have been eliminated, with the consequent elimination of components, which could cause faults and hence require maintenance.
1. Internal combustion engine group of the type comprising a cooling fan installed on the crankshaft of the engine together with a flywheel, characterized in that to said flywheel a rotor of a generator is structurally combined, a related stator being constrained to a case encasing said fan and conveying said air towards an exchanger.
2. Group according to claim 1, characterized in that said rotor is positioned between said flywheel, which is of extremely reduced size, and a start pulley.
3. Group according to claim 1, characterized in that said flywheel is of the type provided with spokes, and bears said fan on its portion opposite to that where said rotor is placed.
4. Group according to claim 1, characterized in that said rotor is of annular shape, so as to allow the cooling air to pass though it towards said flywheel, said flywheel being it too provided with ports suitable to allow the air to reach said fan and said exchanger.
