UA104558C2 - Device for supply of liquefied gas to combustion engine - Google Patents

Abstract

The technical solution proposed relates to the devices for supply of liquefied oil gas (for instance, propane) to combustion engine (CE) and can be used in automobile machine-building. The technical solution claimed is based on the problem on decrease of gas consumption due to collection of rests of gas in the system with its following combustion at next start of the motor. The problem set forth is solved by the fact that in the device for supply of liquefied gas to the CE that includes a vessel for collection of gas that is connected to the pump output of which is connected by means of main for gas supply to inlet collector of the motor through fuel ramp and nozzles the fuel ramp is a body in which a horizontal through channel is provided, this is connected to the gas supply main through electric valve at the inlet and check valve at outlet, at that the nozzles are installed on the body of the ramp, where the gas supply channel is arranged in the lower part of those before dosing needle and connected to horizontal channel of the body of the ramp, besides that the device is additionally equipped with a system of collection of gas rests from fuel ramp after shutoff of the engine, this includes a receiver input of which through the valve for pressure release to receiver is connected to the gas supply channel of the fuel ramp, and the outlet through the valve for pressure release from receiver – to the inlet collector of the engine.
