Abstract: A two part intake or exhaust valve comprising an inner and an outer valve, both circular in shape, with the inner valve having a longer stem of a smaller radius to extend above the outer valve. The outer valve has a hollow stem large enough to accept the inner valve, also a valve seat in the center of its bottom face to seat the inner valve, and the top side of its base is equipped with vents. Both valves have separate springs of appropriate size affixed under valve spring retainers and retainers locked in place with retainer locks. The inner valve is equipped with a groove under the retainer to accept a heavy clip or stop disc. The purpose of this valve mechanism is to create a two stage event when atmosphere enters or exits a combustion chamber. This will allow more atmosphere to enter or exit the combustion chamber than is possible with a single valve arrangement. In addition, this will cause two different speeds of atmospheric movement, creating low pressure in the center, via the inner valve, creating a vortexial storm or swirl effect. The result is more power and better fuel efficiency than can be realized with state of the art valve arrangements.
Abstract translation: 一种两部分进气门或排气门，包括内外两个形状的圆形外阀，内阀具有较长的半径较长的杆，以在外阀上方延伸。 外阀具有足够大的中空杆，可以容纳内阀，也可以是位于其底面中心的阀座，以安置内阀，并且其底座的顶侧配有通风口。 两个阀都有适当尺寸的单独的弹簧，固定在阀弹簧保持器和保持器上，并用固定器锁定在适当的位置。 内阀在保持器下面装有凹槽以接受重的夹子或止动盘。 该气门机构的目的是在大气进入或离开燃烧室时产生两级事件。 这将允许更多的气氛进入或离开燃烧室比单个阀装置可能。 此外，这将导致两种不同的大气运动速度，通过内部阀门在中心产生低压，产生涡流风暴或漩涡效应。 结果是比现有技术的阀装置可以实现更多的功率和更好的燃料效率。

Abstract: A combustion chamber of an internal combustion engine includes a co-axial valve mechanism with a hemispherically concave exhaust valve disk actuated by a single overhead camshaft. A piston face is provided including an offset shallow bowl for accommodating the spark gap of a spark plug when the piston is at top dead center and at least one groove situated at least partially about the shallow bowl. The co-axial valve mechanism and piston face configuration results in more complete combustion and greater power development.

Abstract: A combustion engine has a combustion chamber separated from the compression and expansion chamber(s). Passages are provided between the combustion chamber and the compression chamber(s) and the combustion chamber and the expansion chamber(s) with respective valves in the passages and inlet and exhaust valves provided in the combustion and expansion chamber. The combustion chamber maintains the combustion after passing fuel into the compressed air received from the compression chamber. The valves and piston heads are formed to prevent dead space in the cylinders in order to obtain a good efficiency by full discharge of the compressed air into the combustion chamber. Fuel cleaning means like, for example, a rotary separator and pure gas collector are provided in the combustion chamber to separate unclean fuel particles, as, for example, ash or sand in coal, from the burned gases and collect the unclean particles in separated collection spaces. The engine can thereby burn unclean fuels, as for example coal powder or coal sludge and the like. The valves can be timed for different styles of combustion cycles if so desired. The engine may use conventional four stroke or two stroke engine arrangements and provide them with combustion chambers, pistons and cylinder heads of the invention to modify them from gasoline combustion to coal combustion or other cheaper and more available fuels for the combustion in the compressed air.

Abstract: A four-stroke piston engine in which air or a fuel-air mixture is drawn into a cylinder. Fuel may be injected into the air in the cylinder while a further fuel supply is located on the axis of the cylinder and supplies at least one jet of fuel during the compression stroke, which jet of fuel in cooperation with the fuel-air mixture forms at least one zone of enriched mixture within the cylinder. The piston may have a recess in the upper end into which the nozzle carrier is partially received when the piston approaches top dead center. An ignitable mixture is formed in the recess or in the region of said recess which can be ignited by electrodes disposed adjacent the further fuel supply.

Abstract: This invention presents a method to improve the volumetric efficiency of a reciprocating internal combustion engine using a common transfer port between the exhaust and intake port. The engine employs a poppet valve as part of the intake and exhaust valve to control the flow from the transfer port into the combustion chamber. Two plate type valves outside of the combustion chamber are located at both ends of the transfer port to control the flow coming from the intake and out the exhaust. The timing for opening and closing of the poppet type valve is regulated to remain open for a longer duration which provides complete evacuation of air in the exhaust stroke. The ejector effect from the exhaust flow through the transfer port draws a vacuum into the cylinder. When the exhaust plate closes, the vacuum diverts the intake into the cylinder.
Abstract translation: 本发明提出了一种提高使用在排气和进气口之间的公共输送口的往复式内燃机的体积效率的方法。 发动机采用提升阀作为进排气阀的一部分，以控制从输送口进入燃烧室的流量。 在燃烧室外的两个板式阀位于输送口的两端，以控制从进气口排出的流量。 调节提升阀的打开和关闭的时间，以保持打开较长的持续时间，从而在排气冲程中完全排出空气。 从排气流经传输端口的喷射器效应将真空吸入气缸。 当排气板关闭时，真空将进气进入气缸。
