    Abstract: An internal combustion engine is provided. Facing pistons eliminate a cylinder head, thereby reducing heat losses through a cylinder head. Facing pistons also halve the stroke that would be required for one piston to provide the same compression ratio, and the engine can thus be run at higher revolutions per minute and produce more power. An internal sleeve valve is provided for space and other considerations. A combustion chamber size-varying mechanism allows for adjustment of the minimum size of an internal volume to increase efficiency at partial-power operation. Variable intake valve operation is used to control engine power.

  • Publication number: 20090232673
    Abstract: A method and a device for controlling the oil supply of an automatic transmission (gearbox) and to a starting element. The method can guarantee a sufficient supply of oil to a hydraulic control unit of the automatic transmission and/or the starting element, in particular an oil-cooled friction clutch, both during the operation of the internal combustion engine (4) and when the latter is at a standstill with the aid of an oil pump (2) that can be mechanically driven by the internal combustion engine (4) and a second oil pump (3) that can be electrically driven. In addition, the cooling oil supply of the starting element is guaranteed by the provision of a low-pressure oil by way of the electrically driven oil pump (3), at least during the starting operation, the stream cooling the starting element (11).

  • Publication number: 20090064947
    Abstract: An oil-release space (18) is formed along a lower side portion (17) of a cylinder lateral and peripheral wall (3) below an oil-cooling jacket (4). A reinforcing plate (19) spans between the lower side portion (17) of the cylinder lateral and peripheral wall (3) and a bottom wall (10) of a push-rod chamber (8) below the oil-release space (18). The oil-release space (18) is communicated with an oil outlet (20) of an oil-return passage (7). Engine oil that has passed through the oil-return passage (7) is released from the oil outlet (20) into the oil-release space (18). The engine oil released into the oil-release space (18) is guided by an upper surface of the reinforcing plate (19) to drop from a led-out end (25) on a rear side of the reinforcing plate (19) onto a rear side space (24).

  • Patent number: 7409927
    Abstract: The invention relates to a method and a device for cooling an internal combustion engine. An aqueous, non-ionic coolant composition is used in a cooling circuit (14) of the internal combustion engine (11). In order to also ensure long-lasting protection against corrosion for light metal components of the engine that come into contact with the coolant, e.g. components made of magnesium or magnesium alloys, the cooling circuit has at least one deionization device (28), for example, an ion exchanger, for the coolant.

  • Patent number: 7337755
    Abstract: A cylinder head cooling structure and an oil temperature control system are provided for an internal combustion engine having a plurality of cylinders, each having a plurality of intake ports and a plurality of exhaust ports. The engine includes cooling oil jackets surrounding the spark plugs in the cylinder head, a thermostat attached to the front surface of the crankcase independently of an oil filter, and an oil temperature sensor disposed on a rear face of the cylinder block above the crankcase in an oil supply path formed on the cylinder rear face for supplying oil to the oil jackets. Oil passages conducting oil into the oil jacket are provided between two separate parts of a bifucated intake port and between two separate parts of a bifurcated exhaust port, and only cooling system oil reaching high temperatures is allowed to flow through the thermostat, thereby improving temperature control response.

  • Patent number: 6938605
    Abstract: An oil cooling system to provide enhanced thermal control for internal combustion engines wherein the oil cooling system of the present invention works in conjunction with the standard oil lubrication circuit and typical liquid coolant system of an engine to maintain the engine temperature in a constant range even when operated in an environment with extreme thermal conditions for a prolonged period of time. The present invention detects when the oil temperature has exceeded a pre-determined range and sends the oil to a radiator with heat sinks and a fan for extracting the heat therefrom and dissipating it before recycling it back to the oil sump where it serves to lubricate and cool the heat-generating components it comes in contact with.
