摘要:
The present invention relates to an air supply apparatus (102) for a two- stroke stratified scavenging combustion engine (100). The air supply apparatus includes an air cleaner (124) having an air outlet (130) and a partition (131), such that the partition substantially divides the air outlet into a first section (132) and a second section (134). The air supply apparatus further includes a carburetor (126). The carburetor includes a passage (136), a throttle valve (140) and a choke valve (138), such that the throttle valve and the choke valve substantially divides the passage into an air portion (142) and a mixture portion (144). Further, a first aperture in communication with the first section of the air outlet is provided corresponding to the air portion, and the second aperture in communication with the second section of the air outlet is provided corresponding to the mixture portion. Moreover, an area of the first section is different from that of the second section.
摘要:
The types of gasolines having different distillation characteristics and various compositions are identified accurately and rapidly. A pulse voltage is applied for a predetermined time to a liquid type identifying sensor heater including a heater and an identifying liquid temperature sensor provided in the vicinity of the heater. Then, a gasoline to be identified is heated by the heater, and a liquid type is identified with a voltage output difference V0 corresponding to a temperature difference between an initial temperature and a peak temperature in the identifying liquid temperature sensor.
摘要:
The aim of the invention is to reduce, if not eliminate, the combustion instabilities in a gas turbine, by injecting the fuel along an axis that is off-center relative to the axis of the air/fuel mixing system, thereby inducing a flow of fuel that is no longer perfectly axisymmetric. Specifically, an air/fuel mixing system for a gas turbine combustion chamber according to the invention comprises at least one compressed-air intake swirler (2), the swirler (2) having a central axis of symmetry (X' X), and a fuel injector (3) provided with an injection head (31) having an axis of symmetry (C'C). Each injector (3) is mounted in the corresponding swirler (2) using guide means (23, 22), such that the axis of symmetry (C'C) of the injection head (31) is off-center relative to the central axis of symmetry (X'X) of the swirler (2).
摘要:
A fuel injection system having a fuel injector (22) disposed in a first bore (38) formed in the wall of an air intake passage of an engine. A porous tubular element (32) having a mixture passage (44) open at both its ends is received in a second bore (36) in close contact with the fuel injector (22). An air passage (34) is provided for introducing air into the mixture passage (44) through fine passages formed in the wall of the porous tubular element (32). This air will atomize the fuel (F) adhering to the inner surface of the mixture passage (44) into fine particles (B) in order to form a homogeneous mixture.
