| 20090183699 | Compression Ignition Engines and Methods - Compression ignition engines and methods of the type wherein the engines operate with one cylinder used as a compression cylinder and a second cylinder used as a combustion cylinder. The engines have all cylinders configured so as to be able to operate as a compression cylinder or a combustion cylinder. In the method of operation, a cylinder may switch its operation between being a compression cylinder and then operate a combustion cylinder. Switching the operation between compression and combustion operation results in an even temperature distribution within the engine, and eliminates the need for special cooling requirements, facilitating retrofit of existing engines. Also use of an air storage tank allows all cylinders to operate as combustion cylinders for short bursts of power. Various other features are disclosed. | 07-23-2009 |

A first intake air port and a first exhaust port are located in the up side of the combustion chamber. A compression chamber is connected to the combustion chamber. A central power rod passes through the combustion chamber into the compression chamber and out the compression chamber. A fuel mixture is fed into the combustion chamber and ignition means adjacent to combustion chamber to ignite the fuel mixture. At the end of each stroke, the compression exhaust valves are opened and the intake ports and the exhaust ports are open to permit air from the compression chamber to pass through the conduits into the combustion chamber for full scavenging of the combustion chamber. | 01-08-2009 |

One embodiment of the crankshaft mechanism has its crankpin roller positioned within a novel yoke-arm. The cam mechanism uses a pair of centrally positioned parallel links that are connected to roller cam followers and single or diametrically-opposed pistons. A pair of laterally extending follower arms connects to the ends of the links to provide support and alignment for the piston rods. Between the reciprocating links, cam followers and follower arms is a rotating odd-lobe plate cam. A beam mechanism uses opposite-direction extending balancing beams that are connected to links, cam followers and piston rods. | 06-23-2011 |
| 20100282224 | Combustion Engine with Heat Recovery System - An internal combustion engine has at least two double action internal combustion cylinders and a separate double action compressor cylinder.

Furthermore, the engine has a closed heat recovery system that takes heat from the exhaust of the internal combustion cylinder system and delivers power to a crankshaft. Accordingly, the internal combustion engine has increased efficiency by minimizing friction and extracting energy from multiple sources. | 11-11-2010 |

SOLID FUEL | 2 |
| 20110259286 | Common rail slurry fuel injector system - A fuel injection system is described for injecting slurry fuels into the combustion chamber of a diesel engine, equipped with a fuel common rail, and fitted with a gas to fuel contactor chamber for dissolving supplementary atomizing gas into the continuous phase of the slurry fuel, at high pressure. Each fuel injector comprises a combined double valve for starting and stopping fuel injection, so that slurry fuel containing atomizing gas is only depressurized when injected into the engine combustion chamber, when such depressurization greatly improves fuel atomization and combustion efficiency.

MULTIPLE EXPLOSION | 1 |
| 20110220041 | Accelerated compression ignition engine for HCCI - An internal combustion engine has cylinder wall cavities located near the top dead center stroke end to allow optimizing the compression ratio in first stage compression, as function of fuel octane number used. The volume of the cylinder wall cavities is designed to be adjustable, even when the engine is operating. Using a conventional piston motion, the second stage compression becomes accelerated as soon the upper piston ring seals-off the cylinder wall cavities. This is due to the sudden significant reduction in volume. During the power stroke, after the upper piston ring opens the cylinder wall cavities; their fuel content is ignited by second stage combustion products. Because the torque required during accelerated compression is no greater than during first stage compression, stresses in the crankshaft are no more than in conventional spark ignition engines. This allows small displacement engines to be of light weight and to be hand cranked. | 09-15-2011 |
