Abstract: A liquid primary fuel is ignited by HCCI with the assistance of the early injection of a liquid pilot fuel. Pilot fuel injection and/or ignition are preferably controlled so as to permit the injected pilot fuel to become thoroughly distributed through and mixed with the primary fuel/air charge in the combustion chamber and vaporized prior to ignition. Pilot fuel having a lower autoignition temperature will be ignited by compression ignition, followed by the ignition of the homogeneous mixture of the primary fuel and air. HCCI combustion of the primary fuel is facilitated by 1) selection of the properties of the primary and pilot fuels and 2) obtaining a homogenous mixture of primary fuel and air by injecting primary fuel into the engine's intake air stream in the form of finely atomized droplets having a mean diameter in the micron range.

Abstract: A rotary engine with one or more toroidal chambers defined by rotors that rotate within cylindrical housings. Pistons project into the chambers from the rotors. The pistons cooperate with valves to define compression regions and expansion regions in the chambers. The rotors, the pistons, the valves, or a combination thereof define or include combustion regions of constant volume wherein a fuel-air mixture compressed in the compression regions burns and then is ejected to the expansion regions. Fuel is injected into both the compression regions and the expansion regions, so that the engine operates according to the Trinkler cycle. In a first embodiment of the engine, the valves are rotary and include recesses that accommodate the pistons as the pistons pass the valves. As a piston transits from a compression region to an expansion region via a valve, the space in the valve recess not occupied by the piston is the combustion region.

Abstract: Prior art linear bearings generally have a roller element which, in such a reciprocating motion application, tend to creep or slide along the surfaces upon which they roll. This is due to unequal frictional forces between the rolling surfaces. The linear bearing of the present invention substantially prevents straying and/or sliding of roller elements, and therefore provides bearing functionality at high speeds and great loads with longer longevity and reliability. The linear bearing can be used in many engineering applications, such as in a rotary engine, for example.
