CARBON-REMOVER.

Specification of Letters Patent.

Patented Apr. 12, 1921.

Application filed. February 11, 1916. Serial No. 77,663.

To all whom it may concern:

Be it known that I, CYRUs B. OLSON, a citizen of the United States, residing at Chicago, in the county ,of Cook and State of Illinois, have invented new and useful Improvements in Carbon-Removers, of which the following is a specification. 1

This invention relates to devices for loosening and removing carbon in' internal combustion engines and especially in internal combustion engines of automobiles and motor vehicles, and it has particular referenceto devices for bringing about the removal of the carbon by the injection of steam which may if desired be charged with chemicals of various kinds.

The invention has for its object to produce an improved device of the class described which will be simple in construction. effective in operation, and which will include a supply tank for the water or liquid that is to be vaporized and injected, thereby avoiding the drawing of water from the cooling system, as is now sometimes practised and the disturbance which is apt to result therefrom.

A further object of the invention is to produce a device of the class described which will be simple in construction, effective in operation and capable of being readily installed for use in connection with engines of ordinary construction.

\Vith these and other ends in view which will readily appear as the nature of the" invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will'be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,--

Figure 1 is a perspective view showing the improved device applied to an internal combustion motor of conventional construction.

Fig. 2 is a vertical transverse sectional view of the tank or container and the valve structures associated therewith.

ening and removal of carbon.

Corresponding parts in the several figures are denoted by like characters of reference.

The tank or container 15 is adapted to be seated or mounted on or formed integrally with the exhaust manifold 16 of the engine which is conventionally indicated at 17. The tank 15 has .at its lower end a drain cock 18, and the top of the tank is provided with a filling opening having a screw cap 19, with a safety valve 20 and with an air intake valve 21. The safety Valve which opens outwardly is normally maintained in a seated condition by a spring 22 which at a predetermined pressure will permit the valve to open. The air intake valve 21 is normally maintained in a seated position by aspnng 23 which under predetermined conditions will permit the valve to open for the admission of atmospheric air. A steam pipe 25 1s connected at one end with the tank 15 near the upper end of said tank. 3 Said pipe is provided with a pet cock 26, and a check valve 26 and a portion of the pipe 1s coiled about the exhaust manifold 16, as indicated at 27, but the other end of said pipe is connected with the intake manifold 28, the steam pipe being preferably provided with two branches 29 that are connected with the intake.

In practice, the tank 15 may be filled with water to which any desired chemicals may be added. \Vhen the engine is running the water will be maintained in a heated, usually in a boiling condition, the safety valve 20 serving to relieve any excess of pressure above a predetermined limit. By opening the pet cock 26 the steam will be permitted to pass to the intake manifold, but the steam before being injected into the engine will be further heated by its passage through the coils 27 which are wrapped about the exhaust manifold. 'hen the steam is taken into the engine on the suction stroke of the piston, the pressure in the tank 15 will be perceptibly reduced, and atmospheric air will be admitted through the intake valve 21 which may be adjusted as delicately as may be found desirable or necessary, it being desirable to provide means such as an adjusting screw 30, whereby the tension of the spring 23 ma) be varied. The'mixture of air and steam thus produced has been found extremely efficient to bring about the loos- The air in take valve in connection with the safety valve is also efiicient to prevent splitting of or injury to the steam pipe when -the petcock is closed either by excess of pressure within the tank or by reason of the existence of a partial vacuum within the tank. The device hereinabove described is adapted to act not only as a carbon remover but as a gas saver and economizer and also as a carbon preventive. In other words, when the container 15 is supplied with water or charged with suitable chemicals in solution, the device acts as a carbon preventive, the carbon being prevented from adhering to the surfaces of the combustion chamber, valves, valve seats and the like, and being carried out by the exhaust. Secondly, even though there is no solution or liquid in the container, the air intake valve thereof continues to. work for the rea son that the spring tension on said valve is overcome when the engine is running at a speed which demands a greater supply of air, said intake valve remaining closed at low speed so as to enable the carbureter to deliver a rich mixture to the engine. \Vhen a greater demand for air occurs, the said intake valve of the container is opened automatically and any air passing through the container and through the coils is heated highly before entering the manifold; therefore it materially raises the temperature of the carbureted air passing through the intake manifold and breaks up a great or proportion of the heavier particles of the mixture thereby making a more thoroughly combustible or explosive mixture.

It has been found that with this device attached to or used in conjunction with an intake manifold, the carbureter needs a different or finer adjustment, less fuel and more air being required for the carbureter. In placing this device on engines in which there is already a considerable accumulation of carbon, it is important first to burn out the carbon, in which case the device may be used on a principle similar to that employed in the present day oxygen torch, by placing a. combination of chemicals rich in oxygen in the container, which is heated by the exhaust manifold or in any other way, and extending a pipe or tube from said container into the spark plug hole of one cylinder at a time, after removing the spark plug and while the engine is operating. In such case the engine is first run a sufficient length of time to highly heat the manifold and therefore the mixture in the container 15. If desired, instead of running the engine to obtain the heat, a burner or heater of any suitable description may be placed under the container 15.

Having thus described the invention, what is claimed as new, is I 1. The combination with an internal combustion engine, of a supply tank seated on the exhaust manifold, said tank having a filling opening and a cap therefor, a safety valve and an air intake valve; and a pipe connecting the top of the tank with the intake manifold, a portion of said pipe being coiled about the exhaust manifold.
