AT least 30% more miles per gallon of fuel-this is the prediction of the authors for the Texaco combustion process or TCP typa of engine.
The authors also make the following claims for TCP:
  1. 1.
    It ehminates combustion knock over a broad range of engine operating conditions, regardless of the octane number of the fuel used.
  2. 2.
    It can handle fuels of broad boiling range and it can burn very lean mixtures, with the re- sult that there is a high part-load efficiency and load control by fuel quantity alone.
The conditions to be met for TCP operation and the permissible tolerances on these conditions were investigated by the authors and found to be commensurate with the requirements for construction, servicing, and use of engines.
The requirements for high efficiency of engine operation are also outlined and the progress that has been made in this direction is illustrated by a comparison of TCP thermal efficiencies with those of otto- and diesel-cycle engines.
On a relative efficiency basis TCP is not yet as well developed as the other types, but its value appears to the authors to depend less on results obtainable from future developments than on what is already at hand, namely, that it combines in a single operation the best characteristics of otto- and diesel-cycle engines without introduc- ing the fuel quality requirements of either.
