Estimating the term…
A reciprocating internal combustion engine with balancing and pre-compression is provided. The internal combustion engine comprises: at least one active cylinder, at least one auxiliary cylinder positioned at right-angles to the active cylinder, the throw of the pistons of the relative cylinders positioned on the same drive shaft, and fuel supply parts. Further, the internal combustion engine comprises the auxiliary cylinder equipped with cylinder head with a one-way valve for air inlet and a one-way valve for air outlet. Additionally, the cylinder head of the active cylinder has at least one outlet valve and at least one opening for the inlet of the air into the active cylinder. Finally, the phase of the piston of the auxiliary cylinder precedes the phase of the piston of the active cylinder by 90 degrees. The description includes two-cylinder versions, two-and four stroke, for petrol and diesel cycles, as well as multi-cylinder and turbocharged versions.
Reciprocating combustion engine with balancing and pre-compression, comprising:
Combustion engine as claimed in the previous claim, characterized in that it has a single active cylinder and a single auxiliary cylinder, with both piston rods connected to the same throw of the crankshaft.
Combustion engine, as claimed in one of the preceding claims, characterized in that it has an exhaust turbo-compressor device for the air inlet, connected for its supply upstream of the one-way inlet valve of the auxiliary cylinder and for the exhaust gases downstream of the one or more said outlet valves.
Combustion engine, as claimed in one of the preceding claims, characterized in that the said one-way intake valves and outlet valves of the auxiliary cylinder can be more than one for each intake and/or outlet function.
Combustion engine, as claimed in one of the preceding claims, characterized in that, to achieve the diesel cycle, the said fuel supply parts consisting, advantageously of a pump-injector positioned on the axis of the cylinder head of each active cylinder.
Combustion engine, as claimed in one of the preceding claims, characterized in that, to achieve the petrol cycle, the said fuel supply parts consisting, advantageously of a fuel injector positioned in the supply tube upstream of the said inlet opening/valve in the cylinder head of the active cylinder;
