The secondary fluid may be an accelerant and the primary fluid may be a low pressure fuel/air mixture in a fuel injection arrangement for an internal combustion engine.
An engine includes: a piston; a carburetor having a diaphragm fuel pump, the diaphragm fuel pump including a pump chamber configured to suck and discharge fuel and a diaphragm chamber to which a pressure to drive the pump chamber is applied; and a communicating passage configured to connect between the diaphragm chamber and a negative pressure part in which a negative pressure is created due to movement of the piston. A flowback prevention part is formed in the communicating passage to allow fluid to move only in on direction from the diaphragm chamber to the negative pressure part..
Carburetor system for a carburetor engine
A fuel supply system for small two-stroke internal combustion engines for e.g. Chain saws, line trimmers and similar hand-held power-tools including a diaphragm carburetor (20) equipped with a purging system (80a, 81a) or priming system (80b, 81b) for facilitating starting of the engine (1).
Plugs for carburetors
In accordance with one implementation, a carburetor includes a body having a fluid passage formed therein and a counterbore located along the fluid passage. The counterbore has a first sealing surface and a central axis, and the body further includes a second sealing surface located radially closer to the central axis than is the first sealing surface.
System and improving fuel efficiency in vehicles using hho
A system and method of providing hho gas to an internal combustion engine in a vehicle involves providing a liquid electrolyte solution to an hho generator configured to produce and output hho gas therefrom, separating residual electrolyte solution from the hho gas output by the hho generator, storing a quantity of the hho gas in a pressure tank at a pressure level exceeding an ambient atmospheric pressure, and regulating a rate at which the hho gas from the pressure tank flows to the internal combustion engine with a carburetor device.. .
Carburetors for providing air-to-fuel ratio variability independent of engine load
Carburetor features, which can include but are not limited to varying slope angles in different sections of a multi-sectioned carburetor needle, can provide combustion mixtures to an engine that include a fuel-air ratio that is variable independent of the rate of air flow through the carburetor. Related methods, systems, articles of manufacture, etc.
Plunger valve for a propane carburetor
A plunger valve. The plunger valve includes a body, where the length of the body is between 13 millimeters and 20 millimeters.
A fuel carburetor includes a fuel passage, a heat medium passage, a space part, and an absorbent material. Ammonia as fuel flows through the fuel passage.
Throttle body fuel injection system with improved fuel distribution
A throttle body fuel injection system and method that is arranged to easily replace four-barrel carburetors includes a throttle body assembly with four main bores, each with a throttle plate and an associated fuel injector. Each injector feeds fuel into a circular fuel distribution ring via a fuel injection conduit, which introduces pressurized fuel into the air stream.
Process analysis system with sterile sampling of mechanically-sensitive material from a bioreactor
Method for transport of suspensions containing mechanically sensitive material with a sample-transporting device comprising transport conduits and at least one system for accelerating a sample or aliquot through the transport conduit from at least two burets.. .
Automatic choke for an engine
An internal combustion engine includes a muffler configured to reduce exhaust gas noise. The muffler has a housing defining an interior and an exterior.
Variable venturi and zero droop vacuum assist
An engine includes a carburetor including a variable venturi having a fixed surface and an adjustable surface that form a constricted section, a throttle valve downstream of the variable venturi, a governor assembly including a governor configured to detect an engine speed of the engine, a governor arm coupled to the governor, the venturi, and the throttle valve, and a governor spring coupled to the governor arm to bias the throttle valve towards the fully open position, and a vacuum actuator including an actuator linkage coupled to the governor spring and also coupled to a pressure-sensitive member for movement with the pressure-sensitive member in response to an engine vacuum, and an actuator spring biasing the actuator linkage to increase the tension on the governor spring.. .
Golf ball 2 has spherical core 4, cover 6 situated on the external side of the core 4, and paint layer 8 situated on the external side of the cover 6. The cover 6 has a shore d hardness of no greater than 61.
A carburetor includes a main fuel path connected to a main nozzle and a slow fuel path connected to a slow port. The main fuel path and the slow fuel path are separated from each other and are independently communicated to a constant fuel chamber below a fuel level of the fuel chamber.
Carburetor fuel filter
An on-board fuel filter for a carburetor includes a filter element made from a non-metallic material. The material can be a polymeric material and may be a woven or a non-woven material.
