  • Patent number: 8662032
    Abstract: A crank device and an adjusting device of a combustion engine. The system adjusts the cylinder pressure of the motor in accordance with the required power. Adjustment of the cylinder pressure takes place by changing the compression ration by means of the adjusting device (19). The adjusting device (19) changes an eccentric wheel (3) through an adjusting wheel (4) to a such position that a connecting rod (2) lifts a piston (1) to a desired distance from the combustion chamber head. The adjusting device measures the volume of the air entering the cylinder and adjust the compression ratio to be appropriate. The adjusting device also takes into account the speed of rotation so that the compression pressure increases or decreases to be appropriate.

  • Patent number: 8662036
    Abstract: A method for operating an internal combustion engine includes controlling a variable valve drive for at least one intake valve and at least one exhaust valve of at least one working cylinder of an internal combustion engine in dependence on operating states of the internal combustion engine. The valve drive is variable with regard to valve control times and/or a valve lift. The operating states of the internal combustion engine are defined by load demands, rotational speeds, load conditions and/or torque conditions. Valve operating states of the variable valve drive are set in dependence on the operating states of the internal combustion engine. The valve operating states can increase a charge of a working cylinder, provide an overlap of opening times of intake and exhaust valves, minimize fuel consumption or operate an intake valve in an expansion mode or according to a Miller/Atkinson process.

  • Patent number: 8662040
    Abstract: The invention relates to an oscillating-motor camshaft adjuster having a hydraulic valve, which has two working ports. These two working ports each have a standard opening axially adjacent to one another and an opening for the utilization of pressure peaks as a consequence of camshaft alternating torques. A hydraulic pressure can be guided from a supply port to the working port to be loaded, while the working port to be relieved of pressure is guided to a tank port. In order to also keep the control performance high in the case of internal combustion engines with very greatly fluctuating camshaft alternating torques, it is proposed according to the invention that a position of hydraulic valve can be controlled proportionally, in which the pressure peaks of the working port to be relieved of pressure are blocked relative to the supply port and the working port that is to be loaded.

  • Patent number: 8662058
    Abstract: An electronic ignition module for vintage automobiles that utilizes existing components and wiring to retain the look and operation of the original system but with superior performance. The ignition module replaces the original roller and contacts of a vintage automobile ignition timer with modern control electronics that actuate the original coils and original spark plugs using the original wiring in the original manor. Electronic ignition operation is user programmable to emulate the original roller/timer performance or provide automatic spark advance similar to modern automobile operation for optimum power and efficiency while freeing the operator from manual adjustment of spark timing. Ignition module programming is accomplished without any external switches, buttons, jumpers or modification to the vintage automobile by simply sensing the presence or absence of ignition coils connected to the system when power is applied.

    Abstract: An ignition device has a high voltage transformer having a primary side and a secondary side, of which the primary side is connected to a high voltage source and the secondary side is connected to a spark path to provide the ignition spark. The time variation in the primary current flowing on the primary side is measured and subdivided at least into a spark burning phase and a subsequent free-running phase of the high voltage transformer. The transition from the spark burning phase into the free-running phase is equated to the moment of extinction of the ignition spark. The time variation of the primary current in the spark burning phase is mapped by a first function and in the free-running phase by a second function, and the intersection point of the two functions is equated to the moment of extinction of the ignition spark.

  • Patent number: 8662064
    Abstract: The invention disclosed is an apparatus and method for stabilizing an archery bow and reducing recoil during arrow draw and release. The apparatus comprises an adjustable arm clamp assembly; a rod; a support body for attaching the arm clamp assembly to the rod; and a mounting block for attaching the rod to an archery bow. The archery recoil stabilizer is lightweight, adjustable and relies on bracing the arm from the forearm position to restrict translational and rotational movement of the bow as well as minimize recoil impacts. It supports the arm by bracing the forearm relative to the bow, and reduces or eliminates bow hand torque, providing improved stabilization during both arrow draw and release. Additionally, this invention reduces the stress and recoil on the arm of the archer that can cause pain or injury, or can compromise the flight of the arrow and the accuracy of the shot.

  • Patent number: 8662065
    Abstract: The present invention relates to a portable composite roaster that is small in size, enables a user to selectively use gas, charcoal or the like as a heating means, and is simple and convenient to use for anyone. The roaster has primary, secondary and tertiary heat-isolating screens arranged outside the heating means to effectively isolate heat and to protect a table on which the portable composite roaster is placed or users from heat generated by the heating means such that the users may use the roaster in accordance with the needs thereof. The portable composite roaster of the present invention enables users preferring charcoal-cooked food to roast food using charcoal, and enables users inconvenienced by charcoal to easily use gas instead of charcoal and enjoy delicious food.

  • Patent number: 8662067
    Abstract: Devices and methods for accelerating the combustion of non-gas cooking fuels used in barbequing. The devices include a starting fuel for preparing, or starting, a cooking fuel, such as charcoal briquettes, for use to cook food. The starting fuel is contained in a kindling chamber beneath an upper chamber containing the cooking fuel. A powered air delivery mechanism may provide an airflow to the fuels to increase combustion and heating thereof. In some embodiments, the device is a breach-loading device. In some embodiments, the air delivery mechanism is battery-powered. The device may be configured to provide, and/or may be automated to provide, different operating states responsive to the degree of ignition and/or combustion of the fuels in the device. In some embodiments, the device is adapted to automatically be transitioned between forced-air and natural-draft operating states, which may be controlled responsive to sensed operating parameters of the device.

  • Patent number: 8662071
    Abstract: A household gas appliance includes a gas supply valve which is operated using a magnetic key. The gas supply valve itself may be magnetically operable. In this instance, when a magnetic key is placed adjacent the magnetically operable gas supply valve, the gas supply valve would open. When the magnetic key is removed, the gas supply valve would close. In other embodiments, a magnetic sensor may sense the presence or absence of a magnetic key. If the magnetic key is present, the magnetic sensor would generate an opening signal which causes the gas supply valve to open. When the magnetic key is removed, the magnetic sensor would generate a closing signal which causes the gas supply valve to close.
