Abstract
Abstract A fuel-injection engine with prechamber-torch ignition is of particular advantage in vehicular transport. In this engine, an injector nozzle and a nozzle connecting the precombustion chamber with the combustion chamber are arranged opposite to each other, a channel providing for additional communication between the precombustion chamber and the combustion chamber being made in a wall of the precombustion chamber near the injector nozzle. The distance between the injector nozzle and the precombustion chamber nozzle is such, that during injection a jet of fuel touches the walls of the precombustion chamber and ejects the contents thereof into the combustion chamber, wherein the volume of the fuel jet in the precombustion chamber constituting 0.05-0.25 of the volume of said chamber. Such an embodiment of the engine permits scavenging of the precombustion chamber and removal of exhaust gases from said chamber.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
238 words
A fuel-injection internal combustion engine with prechamber-torch ignition, comprising: a combustion chamber, a precombustion chamber; at least one nozzle and at least one channel associated with said precombustion chamber, said nozzle and channel ensuring communication between said precombustion chamber and said combustion chamber; an injector, provided with at least one nozzle, said injector nozzle being arranged in said precombustion chamber and servicing for fuel feed during the process of injection into said precombustion chamber and into said combustion chamber; said precombustion chamber nozzle and said injector nozzle being arranged opposite to each other; said injector nozzle being disposed at a distance from said precombustion chamber nozzle, whereby during the injection process a jet of fuel enters said precombustion chamber nozzle, touching the inner surface thereof whereby the maximum volume of the cone fuel jet in said precombustion chamber constitutes 0.05 to 0.25 of the volume of said precombustion chamber; said volume of the cone fuel jet is the volume defined by "1" and "d" in the formula V 1 =1/3·(πd 2 /4 1), where 1=the distance between the tip of said injector nozzle and said sectional area of said precombustion chamber nozzle where the fuel jet comes into contact; and d=the diameter of the nozzle of said precombustion chamber where the fuel jet comes into contact; and said channel serves to draw a fuel-air mixture into said precombustion chamber from said combustion chamber by the jet of fuel.
Claim 2
Dependent Claim
238 words
A fuel-injection internal combustion engine with prechamber-torch ignition, comprising: a combustion chamber, a precombustion chamber; at least one nozzle and at least one channel associated with said precombustion chamber, said nozzle and channel ensuring communication between said precombustion chamber and said combustion chamber; an injector, provided with at least one nozzle, said injector nozzle being arranged in said precombustion chamber and servicing for fuel feed during the process of injection into said precombustion chamber and into said combustion chamber; said precombustion chamber nozzle and said injector nozzle being arranged opposite to each other; said injector nozzle being disposed at a distance from said precombustion chamber nozzle, whereby during the injection process a jet of fuel enters said precombustion chamber nozzle, touching the inner surface thereof whereby the maximum volume of the cone fuel jet in said precombustion chamber constitutes 0.05 to 0.25 of the volume of said precombustion chamber; said volume of the cone fuel jet is the volume defined by "1" and "d" in the formula V 1 =1/3·(πd 2 /4 1), where 1=the distance between the tip of said injector nozzle and said sectional area of said precombustion chamber nozzle where the fuel jet comes into contact; and d=the diameter of the nozzle of said precombustion chamber where the fuel jet comes into contact; and said channel serves to draw a fuel-air mixture into said precombustion chamber from said combustion chamber by the jet of fuel.
Claim 3
Dependent Claim
27 words
An internal-combustion engine as claimed in claim 1, wherein: the cross-sectional area of said channel is substantially equal to the cross-sectional area of the precombustion chamber nozzle.
Claim 4
Dependent Claim
36 words
An internal-combustion engine as claimed in claim 1, wherein: the outlet of the precombustion chamber nozzle is so arranged that it is overlapped with the piston head, when the latter is at the top dead center.
Claim 5
Dependent Claim
36 words
An internal-combustion engine ad defined in claim 1, wherein: said channel being disposed to have its end associated with the combustion chamber overlapped by the piston head when the latter is at the top dead center.
