Abstract
Abstract A system of fuel injection and precombustion-chamber spray ignition in piston and rotary-piston internal combustion engines is provided with a nozzle disposed in the precombustion chamber of the engine and connected to a fuel pump, and a jet pump connected to a tank filled with fuel that is provided with a device for maintaining a preset level in it. The tank and the jet pump are connected to the combustion chamber of the engine by a duct in which a shut-off valve is installed for tapping gas from the combustion chamber to the jet pump and tank, the valve having a drive functioning synchronously with the delivery of fuel by the fuel pump.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
172 words
A system of fuel injection and precombustion-chamber spray ignition in piston and rotary-piston internal combustion engines, comprising a fuel pump; a nozzle disposed in the precombustion chamber of the engine and connected to said fuel pump; a tank filled with fuel and connected by means of a duct to said engine combustion chamber; a device for maintaining a preset level of fuel in said tank; a jet pump installed in the inlet pipe of said engine and connected to said tank, designed for injecting fuel into said inlet pipe; a shut-off valve disposed in said duct connecting the tank to the combustion chamber and designed for tapping gas from the combustion chamber into the tank and simultaneously for changing the compression ratio of the mixture depending on the engine duty; the gas, flowing into said tank under pressure, facilitates the suction of fuel into said jet pump and its injection into the combustion chamber; means for actuating said shut-off valve functioning synchronously with the delivery of fuel by the said fuel pump.
Claim 2
Independent Claim
172 words
A system of fuel injection and precombustion-chamber spray ignition in piston and rotary-piston internal combustion engines, comprising a fuel pump; a nozzle disposed in the precombustion chamber of the engine and connected to said fuel pump; a tank filled with fuel and connected by means of a duct to said engine combustion chamber; a device for maintaining a preset level of fuel in said tank; a jet pump installed in the inlet pipe of said engine and connected to said tank, designed for injecting fuel into said inlet pipe; a shut-off valve disposed in said duct connecting the tank to the combustion chamber and designed for tapping gas from the combustion chamber into the tank and simultaneously for changing the compression ratio of the mixture depending on the engine duty; the gas, flowing into said tank under pressure, facilitates the suction of fuel into said jet pump and its injection into the combustion chamber; means for actuating said shut-off valve functioning synchronously with the delivery of fuel by the said fuel pump.
Claim 3
Dependent Claim
30 words
A system as claimed in claim 1, wherein the jet pump comprises an atomizer whose inner fuel delivery tube has one end immersed in the fuel contained in the tank.
Claim 4
Dependent Claim
30 words
A system as claimed in claim 1, wherein the jet pump comprises an atomizer whose inner fuel delivery tube has one end immersed in the fuel contained in the tank.
Claim 5
Dependent Claim
45 words
A system as claimed in claim 1, wherein the device for maintaining the preset level of the fuel in the tank comprises a float closing the outlet orifice of the pipe supplying fuel at its preset level, a non-return valve being installed in the pipe.
Claim 6
Dependent Claim
45 words
A system as claimed in claim 1, wherein the device for maintaining the preset level of the fuel in the tank comprises a float closing the outlet orifice of the pipe supplying fuel at its preset level, a non-return valve being installed in the pipe.
Claim 7
Dependent Claim
56 words
A system as claimed in claim 1, wherein the shut-off valve is spring-loaded and is actuated by a piston valve pusher moving under the action of the fuel delivered to it from the fuel pump, the excess fuel being discharged by the piston valve pusher along a pipe into the inlet system of the fuel pump.
Claim 8
Dependent Claim
