Abstract:
The diesel engine vehicle has a passenger area, and a substantially vertically oriented ventilated chamber separate from the passenger area. The ventilated chamber can be in air flow communication with an engine compartment to evacuate heat therefrom. A heat-emitting exhaust treatment unit can be housed in the ventilated chamber and connected between the diesel engine and an exhaust outlet in an exhaust system of the vehicle.
Abstract:
The diffuser can be used at an end of a vehicle exhaust system. The diffuser can have a generally hollow body with an inlet for receiving exhaust gasses from a substantially vertically-extending component of the vehicle exhaust system, and a substantially flat outlet grate through which the exhaust gasses are to be released to the atmosphere, the outlet grate being configured and adapted for use in a roof of the vehicle, in an aligned position therewith, with the hollow body of the diffuser positioned inside the vehicle and below the outlet grate.
Abstract:
The wing flapping mechanism (100) includes a main frame (110), a pair of opposite wings (120) laterally projecting from the main frame (110), and a linkage arrangement to convert rotation of a motor (150) into a three-dimensional cyclic wing motion of each of the wings (120). The linkage arrangement includes torque-transmitting couplings extending from inside the main frame (110) into the wing structures (122) to transmit an alternating pivoting motion, created as a result of the rotation of the motor (150), to the distal end of a corresponding third torsion-responsive tube (140, 144′″). Each torque-transmitting coupling extends inside a shoulder joint (130), a first torsion-responsive tube (132, 144′), an elbow joint (134), a second torsion-responsive tube (136, 144″), a wrist joint (138) and the third torsion-responsive tube (140, 144′″) of the corresponding wing structure (122).
Abstract:
The system includes a keel fitting that can be rigidly attached directly to the keel of the hang glider. It also includes two elongated frame members symmetrically mounted on opposite sides of the keel fitting. At least one electrical motor is mounted on each frame member and there are at least two propellers, each in driving engagement with a corresponding one of the electrical motors. The system further includes an electrical power unit mounted on the back of the pilot. The electrical power unit includes at least one battery and a pilot-actuated control circuit to vary the electrical power supplied to the electrical motors. The system gives the pilot the capability of taking off from a flat terrain. Once airborne, the system is not operated and the hang glider can then be used as an unpowered one.
