Patent ES-412100-A1 (ES)
Title: Internal combustion engine
IPC: F02M67/00
Filed: 1973-02-27
Abstract: An improved self-injection reciprocating diesel or stratified charge type engine which utilizes pressure in the cylinder to air inject fuel into an adjacent combustion chamber. The combustion chamber and the cylinder space are connected by three separate passages, a small fuel passage, a primary air passage, and a secondary air passage, the secondary air passage being smaller than the primary but considerably larger than the fuel passage. Fuel is delivered by pump pressure to the fuel passage well before top dead center of the piston. As the piston approaches top dead center, it blocks the primary air passage the resulting rapid pressure increase in the cylinder over that in the combustion chamber causes air from the cylinder to flow through the secondary air passage and create a swirl in the combustion chamber, and air to flow through the fuel passage which atomizes part and ejects the remainder of the fuel onto the wall of the combustion chamber from where it evaporates and burns. The secondary air passage, subsequent to the blocking of the primary air passage, provides the flow path for most of the air flowing from the cylinder to the combustion chamber and hence, controls the pressure differential between the cylinder and combustion chamber. Because the fuel passage is substantially smaller than the secondary air passage, it may be cooled without excessive heat losses and at the same time prevent premature evaporation and decomposition of the fuel. This separation and function of the secondary air and fuel passages in combination with self-injection, swirl creation in the combustion chamber, initial atomization of a small fraction of the fuel, and surface deposition of most of the fuel followed by evaporation are the distinguishing features of this invention.

Title: Acceleration enrichment for closed loop control systems
IPC: F02D41/10
Filed: 1978-09-26
Abstract: An acceleration enrichment feature for a closed loop fuel management system controlling the air/fuel mixture delivered to an internal combustion engine to regulate the roughness of the engine at a predetermined level. The enrichment feature provides increased fuel to the engine for operator induced transient conditions proportionately by sensing the rate of change of throttle angle. A throttle angle position signal is modified by circuitry providing a transfer function that introduces a lag term into the throttle angle position signal which differentiating the signal to determine the rate of change of throttle angle. The modified throttle angle position signal is additionally corrected by the amount of roughness sensed by the closed loop control and enriched for rough operations of the engine beyond a threshold and leaned for smooth operations of the engine. Acceleration enrichment pulses of a frequency dependent on the magnitude of the corrected throttle position signal are then combined with the basic fuel injection pulses of the closed loop fuel management system to provide a desired A/F ratio during operator induced transients.

Title: Method of making sign
IPC: B41M3/12
Filed: 1978-10-04
Abstract: For producing character-bearing signs, a transfer material and a temporary intermediate backing film are used. The transfer material comprises a transparent or translucent backing film bearing on one side a plurality of transferable characters. The latter either themselves have sufficient adhesion to permit them to be transferred onto the intermediate backing film or have an adhesive layer on the surface side facing away from the backing film. However, with the aid of an adhesive layer on the temporary intermediate carrier film, the characters can also be transferred onto said temporary intermediate carrier film. The characters are transferred in the arrangement required for the desired sign inscription onto the intermediate carrier film, on which they adhere. Then, with the application of heat and pressure, they are applied onto a transparent sign film on which, with the removal of the intermediate carrier film, they remain adhering.
