摘要:
An engine unit (30) disposed below a storage box is pivotable about a pivot shaft (31) together with a rear wheel with respect to a vehicle body frame. An air intake pipe (36) that defines a part of a main air intake passage (P1) is connected to an engine body (21) of the engine unit (30). An auxiliary air intake passage (K1) branched from the main air intake passage (P1) between a first and second throttle valves (40A,40B) disposed in the air intake pipe (36) is provided. The auxiliary air intake passage (K1) guides intake air into a space adjacent to an injector at least during idling. A pivot shaft (31) is disposed at a lower position than a cylinder axis (L1) of a cylinder block (22) and in a forward direction with respect to a crank case (24).

Eine Vorrichtung zum Einleiten von zusätzlichen Gasströmen in den Ansaugkanal (23) eines Vergasermotors verwendet zwei in Serie hintereinander geschaltete Aufbereitungsvorrichtungen (3,4), wobei jede Aufbereitungsvorrichtung einander gegenüberliegende Schlitze (8,9) aufweist, durch die Zusatzgas in den Ansaugkanal (23) des Vergasers eingeführt wird. Die Schlitzachsen (34) der Schlitze (8) der ersten Aufbereitungsvorrichtung (3) im Vergleich zu der Schlitzachse (35) der Schlitze (9) der zweiten Aufbereitungsvorrichtung (4) stehen senkrecht zueinander, so daß damit eine vollumfängliche Aufbereitung von Kondensat entlang der gesamten Ansaugkanalwandung stattfindet.

An intake air pipe 62 connected to a cylinder head 22 defines a part of a main air intake passage B3. Two throttle valves 69A,69B are disposed in a tubular member 64 spaced apart from each other in an intake air flow direction El.An auxiliary air intake passage C1 communicating with a portion of the main air intake passage B3 between the two throttle valves 69A,69B to guide intake air into a space adjacent to the injector 47 at least during idling is formed. The center axis F1 of the auxiliary air intake passage C1 crosses a plane G2. The plane G2 contains a straight line segment G1 that extends between the opposite ends F2, F3 of the center axis F1.
摘要:
An engine capable of use with multiple different types of fuels including gasoline, alcohol based fuels, and heavy fuels such as diesel, JP5, JP8, Jet A, and kerosene based fuels. The engine (10) includes a main cylinder (25) having a compression chamber (26) at one end and a piston (31) that is movable along the length of the cylinder (25) and which connects to a crankshaft (23) for the engine (10). A fuel delivery system (72) delivers a combustible mixture of fuel and air through a fuel delivery valve (73) into the combustion chamber (26) at a sonic velocity of flow such that the fuel is substantially atomized into the air of the combustible mixture delivered to the combustion chamber (26). The combustible mixture is ignited by an igniter (160) within the combustion chamber (26) to urge the piston (31) along the cylinder for driving the crankshaft (23) of the engine (10).
摘要:
A device for use in association with a carburetor (C) of the type used for supplying fuel at the intake manifold (M) of a gasoline internal combustion engine has an annular chamber (17) at the exit port of the carburetor (C), adapted to collect uncarbureted raw gasoline particles or globules for drainage through an external vaporizing system under the influence of the vacuum created at the intake manifold (M) during operation of the engine for reintroduction as vaporized fuel at the intake manifold (M), thereby converting raw gasoline, otherwise wastefully fed to the engine, into efficiently combustible fuel. The usual throttle butterfly valve (43) of the carburetor (C) is modified to provide a collection chamber (48) for raw gasoline which is continuously withdrawn through an axial passageway (45) in the butterfly valve pivotal axle (44) for drainage through the external vaporizing system.

摘要:
The invention relates to a fresh gas supply device (10) for an internal combustion engine (1) having an exhaust gas turbocharger (2), comprising the following: a charge air inlet (12) for letting in compressed charge air (41) from the exhaust gas turbocharger (2); an outlet (13) which is connected to the charge air inlet (12), wherein said connection can be closed by means of at least one backflow flap (24) that can be pivoted about a rotational flap axis (25); a compressed air inlet (29) for letting compressed air (51, 52) into the outlet (13); an adjusting unit (26) for adjusting the at least one backflow flap (24); at least one additional turbocharging unit (30) comprising an air turbine (33) and a compressor (34) coupled thereto, wherein the air turbine (33) is disposed upstream of the compressed air inlet (29) in the flow direction of the compressed air (51, 52) and compressed air (51, 52) can flow through said air turbine, and wherein the compressor (34) is designed to take in and compress additional charge air (42) from the charge air inlet (12) and deliver compressed additional charge air (43) to the outlet (13).
摘要:
A fuel supply system (10) for an internal combustion engine includes a housing (12) defining a chamber (14) and provided with an inlet opening (16) upstream of the chamber (14) and an outlet opening (18) downstream of the chamber (14). The fuel injector (20) sprays a fuel mist into the chamber (14). A heater (22) heats air flowing into the chamber (14) via inlet (16) to a temperature of between 110 °C-260 °C. Pressure within the chamber (14) is also negative relative to ambient pressure. The fuel sprayed into the chamber (14) via the fuel injector (20) is thermally cracked so that a mixture of thermally cracked fuel and heated air flows out from the outlet (18) for combustion in combustion chambers of the engine.
