Definitions

  • the present invention relates to an apparatus for the filtering of fuel in internal combustion engines. More particularly, the present invention relates to apparatus that separate air and water contaminants from fuel.
  • the diesel engine is an internal combustion engine that differs from the gasoline engine principally in that it relies on heat generated by compressing air in a cylinder to ignite the fuel, rather than on an electric spark. To generate the required heat, the diesel must produce higher compression than the gasoline engine, thereby making it bulkier, heavier and more expensive.
  • the diesel engine also operates more cheaply, on less highly refined fuel, which can give it an advantage in transportation and construction-equipment applications such as locomotives, trucks, tractors, buses, bulldozers, graters, and other heavy-duty machines, and in marine propulsion.
  • Diesel took out patents on an engine to operate on the cycle just described. Either powdered coal or liquid petroleum would be used as fuel. Diesel planned to use compressed air to introduce the coal dust into the engine cylinder but found it difficult to control the rate of injection so that the maximum pressure in the cylinder after ignition would not exceed a safe limit. After the experimental engine was wrecked by an explosion in the cylinder, Diesel gave up the idea of using the coal dust and devoted his efforts to the use of liquid petroleum.
  • a diesel engine is started by driving it from some external power source until conditions have been established under which the engine can be run under its own power.
  • the most positive starting method is by admitting air at 250 to 350 p.s.i. to each of the cylinders in turn under normal firing stroke. The compressed air becomes heated sufficiently to ignite the fuel.
  • S UBSTI UT started, the nature of the connected load, and whether or not the load can be disconnected during starting.
  • Petroleum products normally used as fuel for diesel engines are distillates composed of heavy hydrocarbons, with at least twelve to sixteen carbon atoms per molecule. These heavier distillates are taken from crude oil after the more volatile portions used in gasoline are removed. The boiling points of these heavier distillates range from 350 degrees to 650 degrees Fahrenheit. Thus, their evaporation temperature is much higher than that of gasoline that has fewer carbon atoms per molecule. Specifications for diesel fuels published in 1970 listed three grades: the first was a volatile distillate recommended for high-speed engines with frequent and wide variations in load and speeds; the second, a distillate for high-speed engines in services with high loads and uniform speeds; and the third, a fuel for low- and medium-speed engines in services with sustained loads.
