摘要： A cooling system for cooling intake air in an internal combustion engine. The system comprised of a two-stage turbocharging subsystem having two turbine driven compressors in series with two intercoolers and a closed-loop refrigeration subsystem having cooling coils within or in close proximity to the insulated intake manifold of the engine. This cooled intake air results in a lower peak combustion temperature which results in lower levels of nitrous oxides emitted by the engine exhaust.

摘要： An apparatus for providing a gas phase film lubrication between a reciprocal piston and a cylinder of an uncooled oilless internal combustion engine; the piston is effective to drive a rotary crankshaft in response to an expanding gas charge. The apparatus comprises: (a) means connecting the crankshaft to said piston for transferring reciprocal thrust into rotary thrust, such means aligning the piston concentrically within the cylinder wall to limit the imposition of side loads on said piston (i.e., less than 80 psi); (b) interfacing walls on the piston and cylinder (i) sized to provide a predetermined annular gap therebetween at ambient conditions that has a radial dimension in the range of 0.001.+-.0.0005 inches, (ii) consisting of matched materials that prevent closure of the gap due to thermal expansion under the maximum temperature differential to be experienced between the piston and cylinder wall, and (iii) are preshaped to anticipate any thermal growth of the interfacing walls for maintaining the annular gap substantially constant at elevated temperatures.

摘要： A carbon ignition temperature depressing agent is disclosed along with a method of regenerating an automotive particulate trap using the ignition temperature depressing agent. The agent is effective to promote oxidation of on-board collected carbonaceous particles extracted from the automobile exhaust. The agent comprises (a) an organometallic compound that upon heating (the combustion process of the engine) forms a readily reducible metal oxide which when finely divided promotes a carbonaceous ignition temperature in the range of as low as 450.degree. F. and up to as low as 675.degree. F., and (b) an aerosol-promoting liquid carrier effective to form a fine mist with the organometallic compound when sprayed, the carrier having a boiling point in the range of 176.degree.-302.degree. F. (80.degree.-150.degree. C.). The organometallic compound is one or more metal octoates having the metal selected from the group consisting of copper, nickel and cerium. The organometallic compounds are readily soluble and stable in the fuel supply used with an internal combustion engine such as an automotive diesel engine. The mixture is used in a volume amount of 10-50 milliliters per gallon of fuel or the organometallic compound is present in an amount of at least 0.15-0.5 gm/gal of fuel. The organometallic compound is proportioned to the carrier in a ratio of 1:2 to 1:10. The aerosol-promoting liquid carrier is selected from the group consisting of hexane, pentane and toluene and is effective to promote a droplet size for said mixture when sprayed of substantially less, on average, of one mircon.

摘要： A low-friction piston construction for use in an oil-fed cylinder bore with the piston skirt relieved to define lands that are coated with SFL (graphite, MoS.sub.2, BN, and a special expoxy resin). A method of making such piston construction including provision of asperities on the skirt wall onto which the SFL coating is thermally sprayed and formation of small pockets at the mouth of the asperities to additionally act as oil replenishing reservoirs. A method of using such piston construction in an engine which comprises provisions of a slightly increased gap between the piston and cylinder wall and formation of a transferred SFL coating from the piston to the cylinder wall resulting in two polished microsmooth mating coatings, each attractive to oil films.
