摘要： A four-cycle internal combustion engine has a single or multi-stage pre-cooled compression, which allows the temperature and pressure of intake air to the combustion cylinders to be tightly controlled, so that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the air/fuel mixture auto-ignition threshold. The minimal threshold pressure of air intake is determined to be >1.8 Bars at sea level and a minimal temperature drop of at least 50° C. at the heat exchanger air cooling radiator. Because this design can effectively regulate and set the maximum pre-ignition temperature of the fuel-air mixture, it can combust virtually any type of liquid hydrocarbon fuel without knocking This four-cycle engine, due to its higher compression ratio, generates power equivalent to or greater than a standard four-cycle engine in a smaller and lighter engine and at a higher efficiency.

摘要： A two-stroke engine includes a crankshaft that is rotatable about an axis, and an engine block that includes a combustion cylinder and a compression cylinder. A first piston is slidably disposed within the combustion cylinder and is operatively coupled to the crankshaft for reciprocating movement within the combustion cylinder through a power stroke during each rotation of the crankshaft about the axis. A second piston is slidably disposed within the compression cylinder and is operatively coupled to the crankshaft for reciprocating movement within the compression cylinder such that fresh air is received and compressed in the compression cylinder during each rotation of the crankshaft about the axis. A conduit provides fluid communication between the combustion cylinder and the compression cylinder, and a fuel injector is in communication with the combustion cylinder for admitting fuel into the combustion cylinder.

摘要： Constant pressure internal combustion engine having compression and expansion chambers of variable volume, an elongated combustion chamber of substantially constant volume between the compression and expansion chambers, and a fuel inlet for introducing fuel into the combustion chamber where it mixes with compressed air from the compression chamber to form a mixture of fuel and air that burns as it travels through the combustion chamber. In some embodiments, the combustion chamber is folded back upon itself and has a rough, twisting interior side wall, with long, sharp protrusions extending inwardly therefrom and forming hot spots which help to provide complete combustion of the fuel mixture throughout the combustion chamber. These protrusions, together with flow turbulators within the chamber, promote complete mixing and, hence, combustion of the fuel and air in the combustion chamber.

摘要： An engine block is disclosed in one embodiment having a cylinder shape bore, which forms the outside wall surface of a cylindrical air chamber. Radially outwards from the cylindrical air chamber there is an annular shape combustion chamber, which has a circular inner wall surface, circular outer wall surface, closed annular shaped top surface, and an annular shaped open end opposite of the top surface. The bottom end of the circular inner wall surface of the annular shape combustion chamber and the bottom end of the outside wall surface of the cylindrical air chamber defines an annular shape surface. This surface fits inside the annular shape air chamber in the piston assembly. In one embodiment, in the lower part of the circular inner wall surface of the annular shape combustion chamber there is a circular groove for an oil scraper ring of conventional design.

摘要： Valve assembly and method in which a valve member is connected to an elongated lever arm for controlling communication between two chambers in an internal combustion engine. The valve assembly is disposed at least partially within one of the chambers, and the valve member is moved between open and closed by an actuator connected to the lever arm. In some disclosed embodiments, a pilot valve is opened to equalize pressure on both sides of the valve member prior to moving the valve member toward the open position. In others, where a piston in an expansion cylinder is driven by hot, expanding gases from a separate combustion chamber, the exhaust valve is closed before the piston has completed its exhaust stroke, and pressure is allowed to build up in the expansion cylinder to a level corresponding to the pressure in the combustion chamber before the valve member is moved toward the open position.
