Bifuel Approach to Burning Residual Fuels in Diesel Engines

THIS paper describes the Sinclair bifuel combustion process, a process basically different from either the dual-fuel gas or dual-fuel residual oil systems in its method of fuel utilization as well as its effect on engine operation.The benefits of the bifuel process are not the same for all types of engines. However, the authors report that the following favorable performance results have been observed in tests run in one or more of several engine types: 1. Permits low-quality fuels to be effectively burned under conventional engine operating conditions and at an acceptable exhaust-smoke level. 2. Reduces wear and deposits to a level considerably below that generally obtained with low-quality fuels. 3. Allows the smoke-limited power output of an engine to be increased. 4. Allows operation on fuels normally not considered feasible or practicable in conventional diesel engines.
