Abstract: A remote monitoring system is disclosed. In one such embodiment, a system may comprise a first measuring unit disposed within a structure, a first processor disposed in operative communication with the first measuring unit, and a second processor disposed within the structure. The first measuring unit may comprise a first sensor adapted to detect a first parameter. The first measuring unit may be adapted to output a first signal associated with the first parameter. The first processor may be adapted to receive the first signal and to control the first measuring unit. The second processor may be disposed in operative communication with the first measuring unit and the first processor.

Abstract: A large-bore (at least 180 mm diameter) diesel engine cylinder configuration featuring a piston crown bowl having an acute re-entrant angle and, optionally, an anti-polish ring. The acute re-entrant angle crown bowl involves a maximum radius of the crown bowl exceeding a minimum crown bowl radius, wherein the maximum crown bowl radius is located farther from the squish face than is the minimum crown bowl radius. The acute re-entrant angle crown bowl applied to large-bore, medium-speed diesel engines yields an improvement in performance and emissions characteristics. The anti-polish ring may be integrally formed with the cylinder liner and used in any internal combustion engine.

Abstract: A diesel engine intake cam profile creates two intake valve events separated by a short dwell period each engine cycle. A relatively low valve lift during an engine exhaust event allows a portion of the exhaust gas to flow into an intake manifold and mix with intake air. The intake valve is then nearly closed for a dwell period until a normal intake valve opening occurs, drawing the mixture of air and exhaust gas back into the combustion chamber for compression and burning, upon closure of the intake valves.
