The combustion engine includes a crankcase (14) in which a crankshaft (16) is rotatably mounted about a rotational axis (44). A pressure sensor (27) and a temperature sensor (26) are arranged on the crankcase (14). The pressure sensor (27) and the temperature sensor (26) are arranged in a common sensor housing (31). In the typical put-down position (8) of the work apparatus, the pressure sensor (27) and the temperature sensor (26) are arranged below a plane (45) which is parallel to the horizontal storage surface (7) and contains the rotational axis (44) of the crankshaft (16). A connecting channel (25) is formed in the sensor housing (31). The connecting channel (25) connects the pressure sensor (27) to the crankcase interior (20) and the base (35) of the connecting channel (25) slopes down toward the crankcase interior (20) in the typical put-down position (8) of the work apparatus. | ||||||

| A hand-guided apparatus may include an operating lever, a switch, and an intermediate lever. The operating lever may actuate a function of the hand-guided apparatus, be constructed in an elongated manner and be pivotably attached to a housing of the apparatus. The switch actuates the function and is arranged in the housing. The intermediate lever mechanically actuates the switch. The operating lever includes a safety element enabled to be pretensioned and shifted along a longitudinal axis of the operating lever. The operating lever and the intermediate lever are enabled to be mechanically coupled by shifting the safety element into a pretensioned state to enable actuation of the switch by pivoting of the operating lever. The operating lever and the intermediate lever are enabled to be mechanically decoupled by shifting the safety element into a relaxed state to prevent actuation of the switch by pivoting of the operating lever. | ||||||

| A chainsaw that increases the level of operator safety by reducing or eliminating cut through and kickback injuries without impeding cutting operations, and increases operator comfort through ergonomics, therefore extending stamina. This is accomplished by a dual stage multi-hinged bar device that physically inhibits kickback and cut through injuries. The device, which returns to it's original position after cutting, will open up a total of 88 degrees to allow for cutting of items that are larger than the length of the guide bar. Relocation of the handles leads users toward physically holding the saw in such a manner that creates an ergonomically advantageous body position, reducing fatigue and strains. The body of the saw and the bar device will rotate 45 and 90 degrees both right and left while the handles and operators grip remain in the same position. The chainsaw also incorporates an easy to use chain adjustment. | ||||||
| 170 | Device and method for communication between a control system for small internal combustion engines and an external computer | US11817064 | 2006-03-28 | US07953543B2 | 2011-05-31 | Johan Olsson |
| By incorporating digital control systems for ignition of, and to some extent for fuel injection in, small internal combustion engines, opportunities have been created for the connection of external computers, in order thereby to be able to change the characteristics of the control system, as well as to be able to read operational data from the same. The operational data may be e.g. operating time and trip meter. The method according to the invention means that a combined communication port and stop entry is created, which will result in a cost-effective implementation of the communication interface when a stop entry with an associated transient protection already exists. | ||||||

| A cooling fan includes: a hub; a plurality of cooling vanes provided along an outer circumference of the hub; and an annular connector for connecting the cooling vanes. The hub is provided with a through hole that axially penetrates the hub. A first cover on a case for covering an outward side of the cooling fan is provided with a first outer-air intake. A second cover for partitioning between the cooling fan and a crankcase and for covering an inward side of the cooling fan is provided with a second outer-air intake. With this arrangement, even when one outer-air intake (for instance, the first outer-air intake) adjacent to where the cooling vanes are provided is clogged by a large amount of dust generated during operations, the cooling vanes can breathe from the non-clogged other outer-air intake (for instance, the second outer-air intake) through the through hole, thereby restraining reduction in air flow. | ||||||

| A chain saw has a body in which a stratified scavenging 2-cycle engine for driving a saw chain is laterally housed and a top handle provided above the body. In other words, by laterally disposing the engine, an air port can be installed upward to a cylinder, and an air quantity adjusting device for feeding scavenging air to the air port and the carburetor can be well housed in the top handle. Accordingly, there is no need to separately prepare a space for installing the air quantity adjusting device, so that miniaturization can be achieved. | ||||||
