The machine also has a inlet mouth for admission and discharge of the working medium. A closing element for closing and opening the inlet or the outlet has a valve disk interacting with a valve seat. Either the inlet mouth or the outlet mouth is arranged within the working chamber between the first end surface and the second end surface, and the valve seat and the valve disk are arranged at either the inlet mouth or the outlet mouth.

A radial engine-generator includes an electric power generator and a radial engine. The radial engine-generator can be a mobile and portable unit, and is employable as a primary or back-up source of electric power at data centers, manufacturing facilities, electric vehicle charging stations, medical facilities, telecommunications, and residential neighborhoods, among many other applications. The electric power generator and radial engine are coupled together. The radial engine includes, among other components, multiple cylinders, multiple cylinder heads, and multiple overhead camshaft assemblies. The overhead camshaft assemblies are located at the cylinder heads and each include one or more camshafts. The camshaft(s) receive rotational drive input from a crankshaft of the radial engine. In certain implementations, camshaft carrier assemblies can be provided to support components of the overhead camshaft assemblies.

A valve system/method suitable for an internal combustion engine (ICE), compressor pump, vacuum pump, and/or reciprocating mechanical device is disclosed. The system/method is optimized for construction of a four-stroke ICE. The rudimentary system incorporates a unitized intake and exhaust engine block cover (UEC) that enclose an intake rotary valve cylinder (IVC) and exhaust rotary valve cylinder (EVC) that control intake/exhaust flow through a respective intake rotary valve port (IVP) and an exhaust rotary valve port (EVP) into and out of a combustion cylinder that provides power to a piston and crankshaft. An intake multi-staged valve (IMV) and exhaust multi-staged valve (EMV) provide intake and exhaust flow control for the IVC/IVP and EVC/EVP. An enhanced system may include a variety of intake/exhaust port seals (IPS/EPS), forced induction (FIN), forced discharge (FID), centrifugal advance (CAD), and/or cooling channel spool (ICS/ECS).

An internal combustion engine includes an engine block, a piston, a cylinder head, and a valve train. The engine block includes a cylinder block including a cylinder bore and a crankcase defining a crankcase chamber with a crankshaft positioned within the crankcase chamber. The piston is coupled to the crankshaft and configured to reciprocate within the cylinder bore. The cylinder head is coupled to the cylinder block. The valve train includes a camshaft, a first and second pushrod, a first and second rocker arm, an exhaust valve housed, and an intake valve. The first rocker arm, the second rocker arm, the exhaust valve, and the intake valve each include at least a layer of a low friction material. The first and second pushrod each pass through a pushrod seal to prevent fluid from reaching the rocker chamber to fluidly isolate the rocker chamber from the crankcase chamber.

An OHV engine includes V-shaped banks, a crank shaft, a cam shaft connected to the crank shaft, a mechanical supercharger located between the V-shaped banks, and a power transmission supported by the cam shaft and that connects the crank shaft to the mechanical supercharger. The power transmission includes a gear mechanism with a gear ratio not greater than a predetermined value, and includes a first gear supported rotatably by the cam shaft and that rotates based on an output from the crank shaft, a second gear provided on a rotation shaft of the mechanical supercharger, and an idle gear that connects the first and second gears with each other. Cylinders are offset with respect to a center of the crank shaft on an anti-thrust side of the cylinders, and the mechanical supercharger is also offset with respect to a center of the crank shaft on the anti-thrust side. Cylinder heads are provided with oil cooling paths adjacent respective spark plugs.
