Aspects of the disclosure present a cooler driven by an engine turning a generator wherein the engine and the cooler are not linked by a direct drive shaft.

A compression ignition engine system allows use of hydrous fuels, in particular hydrous biofuels, with high water content (e.g., 20-85% water). The hydrous fuel is pressurized, and also preferably heated via the engine's exhaust gas, to increase its enthalpy, and is then directly injected into the engine cylinder(s) near top dead center. The system provides brake thermal efficiency increases of 20% or more versus a comparable system using conventional diesel fuel, while allowing the use of inexpensive undistilled or lightly distilled biofuels.

Operating a machine system for co-production of electrical power and filtered potable water includes operating an electrical generator by way of rotation of an engine output shaft to produce electrical power, and collecting water condensed from cooled treated exhaust from the engine for delivery to an outgoing water conduit. Operating the machine system further includes supplying electrical power produced by the electrical generator to an in situ electrical load, and to at least one ex situ electrical load such as a power grid. The in situ electrical load is produced by at least one of an exhaust conveyance device, an air conveyance device, or a water conveyance device in a water subsystem.

Operating an internal combustion engine includes conveying fuel of spray plumes of directly injected fuel out of a swirl pocket in a combustion bowl in a piston, and impinging the fuel upon an anti-sooting ramp transitioning between a radially inner shelf surface of the combustion bowl and a radially outer squish surface of the piston. The shelf surface is spaced an axial distance (FA) from a plane defined by the squish surface that is from 1% to 2% of an outer diameter (OD) dimension of the piston. Impinging the fuel upon the anti-sooting ramp directs the fuel upwardly from the squish surface to limit wall-wetting in the combustion cylinder.

A 2-cycle, direct-injection diesel engine configured to accommodate low cetane diesel and jet fuels. The engine includes combustion chambers having surfaces which are operable at high temperatures during engine operation to increase the combustion rate of low cetane fuels. The engine is further configured to reduce starting times in cold and/or low pressure situations such as those experienced during attempts to restart a plane engine at relatively high altitudes.

The present disclosure relates to methods and fuel compositions for reducing fuel injector deposits in gasoline engines operated at high fuel pressures. The fuel compositions include hydrocarbons boiling in the gasoline range and a synergistic fuel injector cleaning mixture.
