US 6,575,147 B2 · Internal combustion system adapted for use of a dual fuel composition including acetylene

Abstract

An internal combustion engine adapted to use an environmentally clean multi-fuel composition, comprising acetylene as a primary fuel and a combustible fuel, such as one or more fluids selected from an alcohol such as ethanol, methanol or any other alcohol or alcohols from the group comprising C1-C12 carbon chains, ethers such as from the group comprising dimethyl ether, diethyl ether, methyl t-butyl ether, ethyl t-butyl ether, t-amyl methyl ether, di-isopropyl ether and the like, low-molecular-weight esters such as from the group comprising methyl formate, methyl acetate, ethyl acetate, methyl propionate, ethyl propionate, ethyl malate, butyl malate, and the like, or other suitable combustible fluid such as mineral spirits and the like, as a secondary fuel for operatively preventing early ignition and knock arising from the primary fuel.

Dependent claims

An internal combustion system for use with a dual fuel source comprised of a primary fuel stream comprised of an amount of acetylene and a secondary fuel stream comprised of a fuel other than acetylene, said internal combustion system comprising:

(a) a conduit having a first end and a second end, said first end adapted for accepting an air source and said second end being affixed to a combustion engine;
(b) a throttle valve disposed within said conduit between said first end and said second end to regulate airflow through the conduit into said combustion engine;
(c) a secondary fuel line received by said conduit between said throttle valve and said second end for delivering a fuel other than acetylene to be combined with said air source in said conduit for subsequent combustion in said combustion engine;
and
(d) a primary fuel line received by a fuel intake port of said internal combustion system at a location downstream of said throttle valve for delivering acetylene fuel directly into said combustion engine for combustion.

(a) a conduit having a first end and a second end, said first end adapted for accepting an air source and said second end being affixed to a combustion engine;
(b) a throttle valve disposed within said conduit between said first end and said second end to regulate airflow through the conduit into the combustion engine;
(c) a secondary fuel line received by said conduit between said throttle valve and said second end for delivering a fuel other than acetylene to be combined with said air source in said conduit for subsequent combustion in said combustion engine;
and
(d) a primary fuel line received by a member of said internal combustion system at a location downstream of said throttle valve, said primary fuel line having an outlet positioned proximal to a fuel intake port of said combustion engine for delivering acetylene fuel directly into said combustion engine for combustion;
whereby said secondary fuel line delivers said fuel other than acetylene into said conduit at a location upstream of where said acetylene fuel enters said internal combustion system.

(a) a conduit having a first end and a second end, said first end adapted for accepting an air source and said second end being affixed to a combustion engine;
(b) a throttle valve disposed within said conduit between said first end and said second end to regulate airflow through the conduit into the combustion engine;
(c) a secondary fuel line received by said conduit between said throttle valve and said second end for delivering a fuel other than acetylene to be combined with said air source in said conduit for subsequent combustion in said combustion engine;
and
(d) a primary fuel line received by a member of said internal combustion system at a location downstream of said throttle valve, said primary fuel line having an outlet positioned proximal to a fuel intake port of said combustion engine for delivering acetylene fuel directly into said combustion engine for combustion;
(e) an acetylene fuel tank designed and dimensioned to hold acetylene fuel and connected to said internal combustion system by said primary fuel line;
(f) a primary fuel valve located within said primary fuel line for controlling flow of acetylene fuel;
(g) a secondary fuel tank designed and dimensioned to hold a fuel other than acetylene and connected to said internal combustion system by said secondary fuel line;
(h) a secondary fuel valve located within said secondary fuel line for controlling flow of fuel other than acetylene;
and
(i) a control mechanism connected to said primary and secondary valves to regulate induction and flow rate of the fuels out of said fuel tanks based on the throttling of said internal combustion system;
whereby said primary fuel line is received by said conduit between said throttle valve and said second end at a location to facilitate said acetylene fuel entering said internal combustion system downstream from where said fuel other than acetylene enters said internal combustion system.
