Engine Deposits-and the Effect of Some Fuel Additives 400148
THE authors report equipment used and procedure followed in determining ratings of fuels and of engines in so far as they affect or are affected by fuel deposits. In other words, this paper is a discussion of fuel-residue ratings.
Their study, they report, indicates that the combustion chamber of any internal-combustion engine, operating under any given set of conditions or under varying sets of conditions, is constantly attempting to attain and maintain an overall equilibrium which is composed of, and is being constantly balanced between, many definitely interrelated and interdependent equilibriums - mechanical, thermal, and chemical.
The disturbing of any one of these equilibriums, they add, must be balanced or offset by compensating changes of one or more of the rest of the equilibriums.
It is also indicated in the study that the maintaining of the deposition equilibrium at a point which reduces its effect on the overall engine equilibrium, both quantitatively and qualitatively, is desirable, and that the obtaining and maintaining of such minimum deposition is possible by use of the proper quantity of the correct type of additive.
