20140261297 | INTERNAL COMBUSTION ENGINES - An engine including at least two piston and cylinder assemblies that, when operating with a fuel savings cycle, establish at the end of the simultaneous compression strokes a charge of compressed air in one cylinder of one assembly and a charge of compressed air fuel mixture in the other cylinder of the other assembly. When the air fuel mixture is ignited, the high pressure conditions in the other cylinder are immediately communicated through a passage to the one cylinder to accomplish a double expansion during the simultaneous power drive strokes thus using much of the pressure energy before exhaust occurs by the pistons themselves. The improvement comprises changing the other assembly which has the charge of compressed air fuel mixture therein between the two piston and cylinder assemblies in a predetermined pattern as, for example, an operative alternation between the two piston and cylinder assembles. | 09-18-2014 |
20140261338 | In-Line Six Internal Combustion Engine - One non-limiting object of the present invention is to provide modifications to conventional in line 6 cylinder engines capable of increasing their efficiency in operation. This includes modifying the central two adjacent piston and cylinder assemblies of the engines. The modifications involve (1) changing the camshaft so that the central two adjacent piston and cylinder assemblies have their four stroke cycles in phase rather than 180° out of phase, (2) providing a communicating passage between the combustion chambers of the central two piston and cylinder assemblies and (3) modifying either the hardware or programming for the control of the fuel injectors of the central two piston and cylinder assemblies so that they can be selectively controlled not to inject fuel during the operation cycle thereof. The modifications contemplates providing a new cam shaft in which not only the cams relating to the central two adjacent piston and cylinder assemblies are modified to change 180° out of phase to in phase, but the cams relating to other piston and cylinder assemblies in order to provide a somewhat balanced application of the driving forces during each cycle. | 09-18-2014 |
20150136069 | INVERTED V-8 INTERNAL COMBUSTION ENGINE AND METHOD OF OPERATING THE SAME MODES - An internal combustion engine having two banks of four piston and cylinder assemblies arranged in an inverted V configuration so that there are four pairs of assemblies each pair having cylinders with adjacent combustion chambers intercommunicated by a passage extending therebetween. Crank shaft driven pistons in said cylinders movable within the combustion chambers thereof through successive cycles each including a compression stroke followed immediately by a power drive stroke. Computer controlled fuel injectors are capable of being selectively controlled to operate either to inject fuel into (1) both cylinders of a pair to establish therein a double fire single expansion mode, or (2) into only one cylinder of a pair to establish therein a single fire double expansion mode with the one cylinder receiving the injection being alternated between the pair every predetermined number of piston cycles. A method of operating the engine as a prime mover of a vehicle having a cruise control system manually actuated to effect automatic movement of a normally manually moved accelerator pedal either in (1) a normal mode wherein the amount of fuel injected is maintained substantially that an optimum level and power variation is obtained in response to manual pedal movements by varying the relative number of injector pairs operating in modes ( | 05-21-2015 |
20150136083 | INVERTED V-8 I-C ENGINE AND METHOD OF OPERATING SAME IN A VEHICLE - In an inverted V-8 engine capable of operating in power level steps with four pairs of piston and cylinder assemblies having fuel injectors with dual options, the improvement which comprises a three component frame structure having cooperating interengaging surfaces containing two banks of four inline crankshaft connected piston and cylinder units converging angularly upwardly from two interconnected crankshafts. The surface-to-surface contact between the block component and head component includes oppositely paired cylinder open ends covered by cam operated valving in the head component with the adjacent upper combustion chambers of each pair of cylinders being communicated by an intercommunicating polished passage formed in a two-piece insert fixedly positioned in a recess in the head component and a method of operating the engine in a vehicle. | 05-21-2015 |
20150142291 | METHOD OF OPERATING AN IN-LINE SIX CYLINDER ENGINE IN A VEHICLE - An internal combustion engine having six in-line piston and cylinder assemblies providing a center pair, an intermediate pair and an outer pair, each pair having crankshaft connected pistons mounted in cylinders through simultaneous repetitive strokes four of which together constitute simultaneous repetitive cycles including a drive event injectors selectively (1) in a (Mode 1) to inject fuel in both cylinders and (2) in a (Mode 2) to inject fuel in only one cylinder, the cylinders of the center pair being intercommunicated by a passage. The effect of skipping an injection in (Mode 2) in the center pair is a pair of shared power drive events and in the other pairs the effect in one of the cylinders is a directly fired power drive shaft and the effect in the other cylinder is deactivation and a method of operating the engine in a vehicle. | 05-21-2015 |
20150342624 | STONE EXTRACTING MEDICAL DEVICE WITH BETTER STONE RETENTION - A medical device comprising a canula having a stone extracting unit on its distal end and a hand piece on its proximal end for operating the unit through the canula. The unit includes more than four annularly arranged tubular elements with fixed proximal ends and distal ends movable between opened and closed position by the movement of an equal number of wire elements extending through the tubular elements with their distal free ends fixed to the distal ends of tubular elements so as to define a 5 or 6 pointed star configuration. | 12-03-2015 |
