Filed:

Dec 12, 2008

Appl. No.:

12/316577

Inventors:

Kent A. Lobsiger - Nashville IN, US

International Classification:

F02B 63/00
H02K 7/18

US Classification:

123 2, 290 1 B

Abstract:

A system includes a shipping container having air inlets at each end and an air outlet at a top and approximate center. The system includes two engines positioned one on each side of a center region, with two generators—each positioned between one of the engines and an end of the container. The center region includes a fuel tank and an air director. An air flow path on each side flows air in the air inlet, over the generator, over the engine, through an engine radiator, mixes the air with exhaust from the engine, and flows out the air outlet. The system maximizes an exhaust flow path length back to the air inlet to prevent exhaust gas recirculation. The system further configures the exhaust air to be heated and released at a higher location than the inlet to minimize potential exhaust gas recirculation.

Abstract:

This disclosure relates a system for heating fuel supplied by a common rail fuel supply to an internal combustion engine. The system includes a high pressure fuel line, plural fuel injectors connected in series along the high pressure fuel line in the common rail, and a continuous low pressure passage including a heat exchanging portion in close proximity to the high pressure fuel line. A heated fluid source is operative to fluidly communicate with the continuous low pressure passage and circulate heated fluid to heat fuel present in the high pressure fuel line prior to, and during a cold start operation of the internal combustion engine. Other embodiments relate to a method of providing fuel to an internal combustion engine that includes sensing the temperature of fuel supplied to a fuel system and determining whether the sensed fuel temperature is greater than a predetermined value. The method includes circulating heated fluid in a continuous low pressure circuit to heat fuel present in a high pressure fuel line if the sensed fuel temperature is less than or equal to a predetermined value, and evacuating fluid for heating fuel from a portion of the continuous low pressure passage and fluidly connecting the evacuated portion of the continuous low pressure passage to a fuel leakage detection device if the sensed fuel temperature is greater than the predetermined value.

Abstract:

A generator set comprises an engine including a crankshaft rotatable in a first direction about a longitudinal axis of the generator set, and a generator including a generator shaft. A gearbox is positioned between the engine and the generator, all mounted on a chassis. The gearbox couples the crankshaft to the generator shaft. The gearbox includes a gearbox housing having a first end and a second end. The first end is coupled to an engine first end and the second end is coupled to a generator first end. The gearbox also includes a gear set including a plurality of gears, a first gear shaft coupled to a crank shaft first end, and a second gear shaft coupled to a generator shaft first end. The crankshaft and at least a portion of the plurality of gears, and the generator shaft are axially aligned along the longitudinal axis of the generator set.

Abstract:

A genset chassis for mounting a genset includes an engine and generator thereon includes a pair of inner beams and an outer beam coupled to an outer sidewall of a corresponding inner beam. The outer beams are vertically offset from the corresponding inner beam such that at least a portion of the outer beams is higher than a corresponding inner beam. The outer beams are structured to be positioned on mounting members positioned on a surface so that a first distance between the at least a pair of inner beams and the surface is less than a second distance between the plurality of outer beams and the surface. The inner beams are structured to mount at least a portion of the genset thereon such that a part of the at least a portion of the genset is lower than the plurality of outer beams.
