A stratified scavenging two-cycle engine includes: an air passage for delivering pure air to a scavenging passage; an air valve for opening and closing the air passage; and an auxiliary air passage for delivering the pure air to the scavenging passage when the air valve is completely closed. An amount of air for air-fuel mixture sucked in a crank chamber is reduced to increase the concentration of the air-fuel mixture, and air that supplements the reduced amount of the air for air-fuel mixture is fed into the scavenging passage through the auxiliary air passage, which enables the engine to be smoothly accelerated even when being suddenly accelerated from an idling state with an appropriate concentration of the air-fuel mixture sucked in a cylinder chamber during idling.
A power transmission mechanism between an engine starter and an engine capable of securely engaging the ratchet wheel of a rotatingly driven part with the lever-like engagement/disengagement member of a centrifugal clutch mechanism when the engine is started. The side face of the lever-like engagement/disengagement member facing the ratchet teeth of a second ratchet part is formed in such a shape that is recessed in a direction apart from the peripheral surface of the second ratchet part in an area starting at its pivoting part toward an engagement/disengagement claw part. The engagement/disengagement claw part formed at the tip of the lever-like engagement/disengagement member is engaged with the ratchet teeth of the second ratchet part by surface contact, and the ratchet teeth of a first ratchet part and the ratchet teeth of the second ratchet part are disposed at a prescribed phase difference.
An insulator (30) in which an acceleration pump fixing portion (51) is provided at the lower part of a heat insulating section (31), and an acceleration pump (50) is fixed to the acceleration pump fixing portion (51). A passage (41) is formed at the lower part of a heat insulating section (31), a groove (42) connecting an insulator air passage (32) with the passage (41) is formed in the connection surface (43) with an engine (1), and a passage (61) connecting the passage (41) with a negative pressure introduction chamber (70) is provided at the upper part of the acceleration pump (50). Consequently, the acceleration pump (50) can be easilyarranged in a space under the insulator (30), which has been essentially a dead space, and, since external piping for allowing communication between the insulator (30) and the acceleration pump (50) can be eliminated, space saving can be achieved and the communication structure can be simplified.
In a brake system (30) for a chain saw, an elongated hole (371) for protrusion is latched to a protrusion (119) when the front end (321) of a belt (32) latched to the body by a latching member (35) is unlatched at the time of an impact and the front end (321) is pulled by the spring force of a compression coil spring (33), and since movement, following up the movement of the front end (321), of the rear end (322) on the side opposite to the pulled side is regulated, a drum (31) can be wound/tightened strongly with the belt (32). Since a chain (20) can be stopped surely, the chain (20) can be protected against breakage when a chain saw (1) is dropped by an impact.

An insulator (2) in which a housing (5) is integrally molded with a heat insulation section (20) at its lower part, where the housing (5) forms a part of a housing (64) of an acceleration pump (6). The construction enables the acceleration pump (6) to be placed at that portion directly around the insulator (2) that is conventionally a dead space, eliminating the need for a dedicated space for installing the acceleration pump to achieve space saving. In addition, because the acceleration pump (6) is at a portion around the heat insulation section (20), even if a pipe is used to interconnect a leading air passage (21) in the insulator and the acceleration pump (6), the length of the piping can be reduced to simplify the structure of the interconnection. Also, since the housing (5) is integrally formed with the heat insulation section (20), the number of parts can be reduced to reduce costs and facilitate assembly of the acceleration pump (6).
An engine blower having a blower (3) and an engine (4). The blower (3) is provided with a fan received in a volute case (31). The engine (4) drives the fan and has a volute (43) for producing cooling air for cooling the engine. The fan, and not a cooling fan for producing the cooling air, is attached to the output shaft of the engine (4). An outlet opening for sending out a portion of pressurized air produced by the fan to the engine (4) side is provided in the volute case (31).

An engine blower having a centrifugal blower, an engine, and a frame for supporting the centrifugal blower. The centrifugal blower is supported by a back stopper with an elastic vibration damping section in between them and fastened to the back stopper by a belt-like stopper (6). An engagement hole (8) is formed in at least either the centrifugal blower or the back stopper section, and a thick-walled engagement section (63) engaged with the engagement hole (8) is formed at the end on at least one end side of the stopper (6). When the stopper (6) is inserted into the engagement hole (8) and the one end side of the stopper (6) is pulled, the engagement section (63) is caused to bite into the engagement hole (8). Thus, the stopper (6) can be reliably attached to the centrifugal blower or the back stopper section.

An engine blower comprising a centrifugal blower having a volute case containing a fan, an engine (4) fixed to the centrifugal blower and driving the fan, a carburetor (5) fixed to the engine (4) through an insulator (40), and a lead wire (7) for allowing the engine (4) and the carburetor (5) to conduct electrically. Since potential difference between the engine (4) and the carburetor (5) can be eliminated, generation of discharge between the engine (4) and the carburetor (5) can be prevented even if static electricity is accumulated on the volute case or the air duct. Consequently, the electronic circuit in an ignition unit can be preventedfrom being influenced by discharge that causes incorrect ignition timing.

A guidance section (23) for guiding the exhaust gas in the exhaust gas guidance member (21) is formed such that the closer it is to the discharge opening (23A), the more it expands to the top surface (24H) side of the cover hood (22).
A muffler for a small two-cycle engine comprises a muffler body having an expansion chamber, an exhaust gas guide member (21) for covering an exhaust gas feed port formed in the muffler body, and a cover hood (22) for covering an exhaust gas discharge port formed in the exhaust gas guide member. An attachment (20) is structured by integrating the exhaust gas guide member (21) with the cover hood (22). The attachment (20) can be so slid in relative to the muffler body that the attachment is capable of freely engaging with or disengaging from the muffler body.
Screw holes (79A, 79B, 79C, 79D) are formed in a joint surface (76) of an insulator (7) so as to enable a carburetor (8) to be fixed to the insulator at any of positions about the axis of an air intake hole (74). The insulator (7) is fitted to a predetermined position of a cylinder (3), and the carburetor (8) is mounted on the insulator (7) by inserting bolts (11) into the screw holes (79A, 79B, 79C, 79D) through through-holes (85A, 85B) of the carburetor (8). Because the carburetor (8) can be fixed to an engine body (2) at any of positions about the axis of the air intake hole (74), the direction of projection of a throttle lever (84) fromthe carburetor (8), i.e., the direction in which the throttle lever (84) is operated, can be changed.

A stratified-scavenging two-cycle engine (1) has a leading air passage (700) for feeding leading air to a scavenging passage (9), an air valve (430) for opening and closing the leading air passage (700), and a sub passage (100) for feeding the leading air to the scavenging passage (9) when the air valve (430) is fully closed. The above construction reduces air for air-fuel mixture sucked into a crank case to increase the concentration of the air-fuel mixture, and as a result, air with an amount equivalent to the amount of the reduced air is fed into the scavenging passage (9) through the sub passage (100). This enables the engine to be smoothly accelerated even in quick acceleration from its idling condition, with the concentration of the air-fuel mixture sucked into cylinders during the idling maintained at an appropriate level.

A two-cycle engine (1) has a starting fuel feeding passage (200) for feeding a starting fuel from a starting fuel containing part into a crankcase (24) and also has a flow passage opening/closing means installed in the middle of the starting fuel feeding passage (200). The starting fuel feeding passage (200) is always opened at a position communicating with the inside of the crankcase (24). Therefore, operation for feeding the starting fuel into the crankcase (24) can be started at the same time when a negative pressure is produced in the crankcase (24) when a piston (27) changes its direction of movement to upward movement from the bottomdead center. Because the starting fuel can be fed into the crankcase (24) for a time period longer than that required in conventional products, the amount of fuel sufficient to start the engine can be fed to the engine. Consequently, startability of the two-cycle engine (1) can be improved.

A muffler (10) of an engine blower as a working machine includes a muffler body (11) and a diffuser (15) covering an exhaust gas exhaust opening (13) arranged on the muffler body (11). The diffuser (15) has a diffusion space for diffusing an exhaust gas and an exhaust plane (31) where a plurality of exhaust circular holes (33) are formed for exhausting the diffused exhaust gas outside. The opening ratio obtained by the exhaust holes (33) with respect to the exhaust plane (31) is gradually increased from the portion corresponding to the exhaust opening (13) toward the external circumferential side.
A start device for a small-sized engine, which can start the engine in an appropriate start time and which is ultimately reduced in size and weight by rational design. The start device has a small-sized electric motor (131) and secondary batteries. The batteries are used as the power source necessary for the drive of the small-sized engine, have a relatively large capacity, and are extremely reduced in size. A reduction gear mechanism (132) with a reduction ratio of 1/30 - 1/90 is placed between the electric motor (131) and a cushioning and force storage section (110). The start device can start the engine in an extremely short time of 0.4 - 1.3 seconds which does not cause any inconvenience to the operator.
A chain saw 1 has a body 3 in which a stratified scavenging 2-cycle engine 5 for driving a saw chain 21 is laterally housed and a top handle 41 provided above the body 3. In other words, by laterally disposing the engine 5, 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 41. Accordingly, there is no need to separately prepare a space for installing the air quantity adjusting device, so that miniaturization can be achieved.
A chain saw 1 includes a body 3 in which an engine for driving a saw chain 21 is laterally housed; a top handle 41 provided above the body 3; and a muffler 6 arranged below the engine, in which an exhaust outlet 640 for discharging exhaust from the body 3 side to the outside opens forward from the body 3 side. Accordingly, not only the exhaust can be discharged forward from the side of the body 3, but also the exhaust sound can be propagated forward so that less exhaust sound is heard by the operator, thereby improving the work environment.
A carburetor 1 includes: an intake passage 21 for allowing intake air to an engine to flow therethrough; a fuel storage section 22 for storing fuel from a fuel tank; a starting fuel supply passage 30 for supplying starting fuel from the fuel storage section 22 to the intake passage 21; and a solenoid valve 3 provided in the middle of the starting fuel supply passage 30. At least a part of the starting fuel supply passage 30 between a fuel intake portion 31 and the intake passage 21 is formed in a straight line. Thus, pressure loss of the fuel between the fuel intake portion 31 and the intake passage 21 is suppressed, so that the fuel can be easily extracted to the intake passage 21 by the negative pressure generated in the intake passage 21without stagnating. Accordingly, the optimal amount of the starting fuel can be supplied to the engine when the engine is cold, so that the startability of an engine can be secured.
