ARRANGEMENT FOE PURIFYING AND RENDERING ODORLESS THE EXHAUST GASES OF INTERNAL-COMBUSTION ENGINES AND THE LIKE.

Application filed September 23, 1920. Serial No. 412,341.

' rangement for purifying and rendering odorless the exhaust tion engines and t automobiles.

Numerous apparatus have already been suggested for the purpose stated which generally were based onthe principle of conducting the burnt gases ejectedthrough containers provided with chambers. The ldea of conducting the exhaust gases through a hollow body is obvious, on theone hand for reducing the noise caused by them, on the other hand to purify the gases passing through the various chambers. Heretofore, however, and in particular as regards automobiles, no such apparatus have been dlsclosed which have proved fully satisfactory. The reason for this may be sought'in the fact that the method hitherto employed for purifying these exhaust gases was one-sided only, as the gases, consisting of the burnt gases and residues of the oil were conducted through the same chambers. the disadvantage that the oil particles car'- ried along in the gases completely coated the purifying materials in the said chambers with a film of oil, whereby the effect which ases of internal combusdie like, in particular with was expected from these ,materialsbecame negative.

The essential idea of the present inventi'on'resides in the oil particles being carried along in the gases and first separated from the combustion gases. This object is obtained by means of a preliminary cleaner whilst the purifying proper of the exhaust gases is carried outin a separate chamber, subdivided into a plurality of sub-chambers anddisposed above the preliminary cleaner. This method has by experiments been proved to be particularly satisfactory and it has been found that the heavy oil particles are readily deposited by heated coke as they are This method showedkept in a liquid state, andthat the volatilegasol1ne gases separate therefrom. Only after thls process has beencompleted' the gasoline gases can be cleaned'and rendered odorless by means of a separate apparatus subdivided into a plurality of chambers.

I A considerable improvement over other known arrangements consists in the supply of fresh air into the interior of the apparatus, This fresh air, however, is introduced only lnto the gas purifying chamber andcondensed there. The water particles are carried on into the various chambers so as to keep the purifying materials, such as spagnum and other porous substances, permanentl the comli from the oil residues.

In the'accompanying drawing Fig. 1 ,is a longitudinal section,

' Fig. 2 a transverse section through the apparatus forming the subject matter of the present invention.

The apparatus consists of a container A, preferably of cylindrical section and containing two sections A and A, se arated from each other by a partition B. he exhaust gases are, afterleaving the motor conducted through a webbed steel pipe E into the lower oil-removing chamber, which is filled with small pieces of very porous coke. By means of the webbed steel pipe E the to separate and absorb the oil particles from the exhaust gases. The absorbed oil particles, which are in a very liquid state, may from time to time be drawn oif through the tap H. The exhaust gases, after having thus been freed of the burnt oil, ass through the opening D in the partition 1? into the upper, gas-purifying chamber A which is subdivided into a plurality of chambers, which communicate through openings 05. These openings are staggered with respect to each other, so that the gases, while passing through the chambers, are forced to fully utilize the purifying material in the chambers. ,In order that the latter, consisting moist and capable of absorbing stion gases which have been freed Specification of Letters Patent. Pate t d J 10 1922 i 8 5 coke will be evenly heated so as to adapt it in the direction of travel, so as to suck in fresh air. From this funnel the air is conducted through pipes F into the first chamher 0. At the inner edge of the pipes F is disposed a water pocket K, which reaches down to the bottom of the partition B. The air sucked in through the funnel is forced in the water pocket toward the heated. bottom of the partition 13, where it condenses, and the water particles thus produced will be carried along by the current of gas and be absorbed by the purifying material. The gases eventually emerge in form of white vapor and absolutely odorless through the last chamber G into the atmosphere.

The essential feature of the invention consists, aswill be apparent from the foregoing description, in the fact that the apparatus is composed of the two separate parts, in which quite different processes are carried out, namely in chamber A the absorbing of the oil, and in chamber A the actual purifying of the gases. Both parts of the apparatus cooperate in producing the final object desired. After 6 to 8 weeks the apparatus should be cleaned and the fillin be renewed. For this purpose the rear lid is detached, and the whole interior system of chambers may then be drawn out, cleaned and refilled. For facilitating its removal the partition B is guided in rebates.
