This form of engine, designed by Mr. Edwin W. Evans, has just (1893) come upon the market. In general it is similar to the many small vertical engines having the Otto cycle, etc., as usual with the cylinder at base. Its distinctive feature, however, is the use of but one simple rotary balance valve for performing all the functions of gas and air mixing, admission, exhaust and ignition, covered by letters patent for December 13, 1892, NO. 488,165. This is external and easily gotten at, and the concentration into one of what is usually covered by several moving parts, is certainly an attractive feature. The engine is as yet too new to have a record, but it promises to be a satisfactory one.
A bevel gear drives the valve. Tube ignition is used. The engine is handled by the Evans Gas Engine Co., 23 South Front Street, Philadelphia, and is made so far in sizes from 1½ to 5 Ind. H.P. |
