A structure for fitting a fuel tank in an automotive vehicle comprises a rear floor panel fixed at a rear portion of the automotive vehicle, a rear seat cross member fixed to the under side of the rear floor panel across the automotive vehicle, a seat belt anchor fixing cross member fixed to the under side of the rear floor panel across the automotive vehicle, and a pair of bands suspended between the rear seat cross member and the seat belt anchor fixing cross member for supporting the fuel tank in position between the rear seat cross member and the seat belt anchor fixing cross member.

An end-burning grain of a solid gas-generating composition which may be a propellant for use in rocket motors, in which an elongate metal heat conductor is embedded to increase mass burning rate by the effect of heat transferred from the hot combustion gas to the unburned gas-generating composition through the heat conductor. The improvement resides in that the heat conductor is constituted of a plurality of relatively thin wires which are loosely twisted together. This heat conductor can produce greater extent of increase in the burning rate and has a mechanical strength sufficient for embedding in a practical grain.

In an electronically controlled ignition device for a combustion engine, firstly an ignition timing and an energized angle of an ignition coil are calculated with response to running condition of the engine, secondly a non-energized angle of the ignition coil is calculated based on the result of the above calculation, thirdly the number of pulses generated with response to the angle of revolution of the engine is counted from the preceding ignition timing, so as to start the energizing of the ignition coil when the result of the above count coincides with the result of the above calculation of non-energized angle, and fourthly the number of pulses generated with response to the angle of revolution of the engine is counted from a reference position of revolution at which a reference pulse is generated by the revolution of the engine, so as to cut off the energizing of the ignition coil when the result of the above count of pulses coincides with the present ignition timing. Consequently, the ignition timing can be shifted with response to the running condition of the engine and the necessary energizing time duration for the ignition coil can be secured by correcting the energizing timing with response to the above shift of the ignition timing, so as to insure the energized time duration required for the ignition coil with a comparatively simple configuration.

An exhaust gas recirculation control system for an internal combustion engine of a motor vehicle, comprising an exhaust gas recirculation control valve for controlling exhaust gas recirculated back to the engine when opened, and means for fully opening the exhaust gas recirculation control valve for a predetermined period of time when operating condition of the vehicle reaches a predetermined level, thereby preventing exhaust gas recirculation from performing with a delayed time relative to a required timing.

A channel for recirculating a portion of an engine exhaust gas to the induction passage has an intermediately arranged converging-diverging supersonic nozzle with a valve member arranged in the nozzle to vary the cross-sectional area of the channel at the throat, so that the mass flow rate of the recirculated exhaust gas depends solely on the cross-sectional area so far as the gas velocity at the throat is sonic.
摘要:
A device for detecting whether any of a plurality of fuses has blown out. The fuses are connected between a first terminal of an electrical source and a number of loads, the loads also being connected to the other terminal of the source. The device comprises one light emitting element for each fuse. One end of the light emitting element is connected to a junction between the fuse and its load. The other ends of the light emitting elements are all connected together to one terminal of a switch, having another terminal connected to the other terminal of the electrical source. When the switch is closed, the light emitting element corresponding to any fuse which has blown out is not lit.

In an engine having an even number of cylinders, the cylinders are divided into two groups each consisting of half the number of the total cylinders, and the two groups are fed with a considerably rich air-fuel mixture and a lean one, respectively. Each of the one group of cylinders is arranged to discharge an exhaust gas rich in HC and CO simultaneously with discharge of another exhaust gas rich in air from a predetermined cylinder of the other group, and the exhaust gases are mixed and reacted with each other in the engine exhaust system.

Herein disclosed is an automotive spark-ignition valve-in-head internal combustion engine of the type which has main and auxiliary combustion chambers wherein combustion is initiated in the auxiliary combustion chamber and the resultant flame squirts into the main combustion chamber through a flame passageway whereby the flame fronts radiates out throughout the main combustion chamber from the outlet end of the flame passageway. The outlet end of the flame passageway is located about a "small-clearance-volume" portion of the main combustion chamber so that the flame fronts travel from the small-clearance-volume portion toward a "major-clearance-volume" portion. The small-clearance-volume portion largely corresponds to a squish-quench area in a combustion chamber of the turbulence type such as the wedge combustion chamber.
摘要:
An additional passageway is prevented from supplying additional air into an engine intake passageway downstream of a throttle valve and alternatively the throttle valve is prevented from being opened a predetermined amount when the temperature of a catalyst of an engine catalytic converter is below an allowable limit during deceleration of the engine.

Two headlight frames are mounted on the vehicle body front to be tilted about their lower peripheries and are usually preloaded by a spring assembly to be limitedly tilted. A manually operable lever accessible to an operator is movable to and is held in the selected one of multiple operating positions. The manual operating effort applied to the lever is transferred through a linkage including cables or rods and pivotal levers to the headlight frame to maintain it in a certain tilted position corresponding to the selected position of the manually operable lever.
