摘要： A ventilation device of an agricultural vehicle such as a combine, forage harvester or tractor having an engine (10) and a cooling device (12) for cooling the engine (10) and/or additional parts to be cooled that are in a heat conducting relationship. The ventilation device comprises a fan (20) a fan drive (18) and a control system (26) connected to the fan drive (18) to regulate the feeding rate of the fan (20). The control system (26) is arranged to control the fan drive (18) in the most energy-efficient way while making allowance for the amount of ambient air required by the cooling device (12) and the drive power requirements of the fan (20) using a flat logic (fuzzy control).

摘要： This invention concerns a two-stroke cycle engine, more specially it concerns a two-stroke cycle engine using a preceding air-layer for scavenging. It has a scavenger passage connected to a branching scavenger passage opened to said scavenging port. The engine has a connecting passage to link the air passage and the fuel passages so that negative pressure in the air passage forces the fuel-air mixture in the fuel passage into said air passage. Further, the engine according to this invention has a removable guide with a surface forming a curved smooth channel which is attachable to the scavenger passage in the crankcase from the mounting surface, and forms a portion of said scavenger passage with the curved channel. The blow-up angle of the scavenger passage varies along the circumferential direction of the cylinder. The crankcase is configured in such a way that the front and rear portions, which are separated by a block, and a scavenger passage is provided inside both said front and rear portions of said crankcase, and the cylinder. The air cleaner has two air passages running from it in parallel, the first one is connected to said air passage, and the second one is connected to the air inlet of the carburetor to provide air for the fuel passage, and a choke valve on the air cleaner is provided to open and close both of the first and second air passages.

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： An electronically controlled magnetorheological fluid based fan drive assembly 60 used to increase the rotational speed of a coupled radiator cooling fan. Introducing a magnetic field within a working chamber 99 between a drive ring 74 and an output member 86 increases the viscosity of a magnetorheological fluid by changing the state of the fluid from a free flowing liquid to a semi-solid state. The shear rate of the magnetorheological fluid can be increased to create additional torque to drive the output member 86 and coupled radiator fan at a higher rotational speed to cool the engine coolant flowing through a closely coupled radiator. The magnetic field is induced by directing a flow of electrical current through an electronic coil 62 coupled within the fan drive assembly 60, and an electronic control unit coupled to the electronic coil 62 controls the amount of electrical current flowing through the coil 62. This maintains the temperature of the engine block within an acceptable temperature range at a particular engine speed.

摘要： A hand-held working tool has a housing and an internal combustion engine arranged in the housing and comprising a crankshaft and an air filter. A tool is driven by the crankshaft of the internal combustion engine. A fan housing is attached to the engine housing and has an air inlet. A fan wheel is arranged in the fan housing and is driven by the crankshaft of the internal combustion engine to supply cooling air, sucked in through the air inlet, to the internal combustion engine. The fan housing has a bottom extending radially to the crankshaft. The bottom and a side of the fan wheel facing the bottom define a chamber in the fan housing. The bottom has a combustion air outlet. A combustion air channel is connected to the combustion air outlet and to the air filter. The combustion air outlet is axially supplying combustion air from the chamber through the combustion air channel into the air filter of internal combustion engine. The fan housing has a channel wall having a bottom portion connected to the face of the bottom remote from the fan wheel and covering the bottom partially to form a double-walled bottom. The end face portion of the combustion air channel is defined by the bottom and the bottom portion of the channel wall. In an alternative embodiment the combustion air channel is provided in a hollow beam of a support that supports the drive unit of the working tool.
