摘要： The present invention provides a method and apparatus for efficiently cooling a motor. Three components may be used to provide forced air through a motor and a motor bearing. An air guide plate may direct air in and out of a motor and move air through a bearing seal, a shaft, and the motor. The air guide plate also may shield the bearing from heat. A series of holes, with every other hole an inlet hole or an outlet hole, within the motor housing may be arranged in a common radial plane. The incoming air does not mix with the outgoing air. A series of fins on a rotor may move air in and out of the holes within the motor housing.

摘要： A flywheel (1) for an internal combustion engine is provided for generating a cooling air flow and is especially for a two-stroke engine on a portable handheld work apparatus such as a motor-driven chain saw, cutoff machine or the like. The flywheel (1) carries a parallelopipedly-shaped permanent magnet (5) for a magnetic ignition system. The permanent magnet has a short edge (6), a center edge (7) and a long edge (8). The permanent magnet (5) is polarized in the direction of the short edge (6). To provide a high moment of inertia of the flywheel (1) while achieving a low weight, the short edge of the permanent magnet (5) runs tangentially to the peripheral direction of the flywheel (1) and that the long edge (8) of the permanent magnet (5) is aligned parallel to the rotational axis (11) of the flywheel (1).

摘要： A malfunction of a thermostat in a coolant circulating path is detected from an engine side coolant temperature in consideration of the following behavior of the coolant temperature. When an open-malfunction occurs, the coolant temperature becomes different considerably from that in the normal time in the temperature range in which the thermostat is to be normally closed. When a closure-malfunction occurs, the coolant temperature becomes different considerably from that during the normal time in the temperature range in which the thermostat is to be normally opened. Alternatively, the malfunction may be detected from a difference between the engine side coolant temperature and a radiator side coolant temperature.

摘要： A cooling unit includes a radiator and an axial flow blower that draws air through the radiator along a longitudinal axis and a cross-flow fan that draws air along a lateral axis. The cross-flow fan forces air through the radiator along the longitudinal axis. The axial flow fan draws air through the radiator long the longitudinal axis. A moveable baffle is operable to selectively block air flow from the cross-flow fan.

摘要： The invention relates to an intake system (1) for the combustion air (2) of an internal combustion engine (3) in a portable handheld work apparatus (4). The intake system (19) includes a filter housing (5) having an air filter (6) for purifying the combustion air (2). The clean space (8) of the air filter (6) is fluidly connected to an outlet opening (10) of the filter housing (5). The outlet opening (10) communicates with a carburetor (7) of the engine (3). A centrifugal-force separator (13) is mounted forward of the air filter (6) for separating large amounts of dust in the inducted combustion air (2). The separator (13) is so positioned ahead of the filter housing (5) that a central core flow (14) of the separator has a lower particle density (15) and is supplied to the filter (6). A tangential flow (16) surrounds the central core flow (14) in the interior of the separator (13). The tangential flow (16) has a great amount of dust or dirt and is conducted away via the suction side (11) of a blower (12), especially of a cooling-air blower (19) of the engine (3) having vanes on the back side thereof.

摘要： A fan drive arrangement and method is provided for facilitating the cooling of engine coolant flowing through a radiator and an engine. The fan drive arrangement includes a variable pitch sheave assembly which moves between a first high speed position and a second low speed position. Variable pitch sheave assembly is interconnected by first and second drive belts to first and second drive pulleys operatively connected to the crankshaft of the engine and by first and second fan belts to corresponding fan pulleys connected to a fan shaft of a fan. Variable pitch sheave assembly includes first and second drive belt receiving grooves for receiving corresponding drive belts therein and first and second fan belt grooves for receiving corresponding fan belts therein. The depths of the fan belt grooves and the drive belt grooves of the variable pitch sheave assembly are varied in response to the temperature of the engine coolant flowing through the radiator so as to vary the fan speed accordingly.

摘要： A temperature sensing device for an internal-combustion engine includes a carrier structure, a first sensor element accommodated on the carrier structure, a second sensor element also accommodated on the carrier structure, an engine air guiding device for feeding an engine intake air flow to the first sensor element, and a radiator air guiding device for feeding a radiator air flow passed through an engine radiator to the second sensor element. By way of a compact constructional unit, which can be preassembled, it is possible to centrally sense the temperatures of the two air flows. The obtained measuring signals can be coupled into a cable tree system provided on the vehicle side while the cabling expenditures are reduced.
