Device and method of regulating the start of fuel injection in an otto engine

Abstract: The invention relates to a device and a method which can be applied primarily to computer controlled fuel systems for Otto engines, with sequential injection of fuel in each cylinder to the inlet valves. In order to utilize the capacity of the hot inlet valves for evaporating the fuel, in normal operating cases, the invention is characterised in that the start of injection (60) is continuously adapted to the prevailing fuel demand and the injection time consequently required, so that the injection D is substantially completed before the inlet valve A towards which the injector is directed will begin to open (50). The control of the start of injection according to the invention provides, by simple means, improved evaporation of the fuel and more homogeneous fuel-air mixture, which in turn provides a more complete combustion and reduced emissions.

Snag free reversible camouflage netting

Abstract: A camouflage construction comprises a first base layer having a top side defining a first camouflage motif and an opposite bottom side defining a second camouflage motif. A second garnish layer, formed from a plurality of elongated strips each having a central longitudinal axis extending between opposite ends of each strip, and a plurality of slits formed transverse to each strip longitudinal axis so that a plurality of fingers are formed on each side of the longitudinal axis so that each finger has a first end that is attached to a continuous central portion of the strip and a second end that is free to move with respect to the first end and adjacent fingers, are bonded to the first base layer top side along the central longitudinal axes to form a three-dimensional motif on the first base layer top side.

Simulation of Human-Vehicle Interaction in Vehicle Design at Saab Automobile: Present and Future

Abstract: Developers, reviewers and users of human simulation tools claim that the use of these tools may reduce development time and development cost. However, before these benefits will be fully visible, there are some barriers to overcome. The aims of this case study are to identify which departments at Saab Automobile use some sort of human simulation tool today, and to identify the information flow and procedure when the tool is used. Four departments crash safety, packaging, production planning and vehicle ergonomics were identified as direct users of human simulation tools. The tools used were finite element with crash dummy representation, SAE human model, Safework and Ramsis. Communications between human simulation tool users are limited. Communications are done through the project management. The crash safety and packaging departments have formal descriptions of the human simulation process, whereas production planning and vehicle ergonomics have no formal process descriptions. To gain from the benefits of human simulation tools, Saab Automobile needs to adapt them to the organization and the organization to the tools. Integration of a working methodology is essential for effective and efficient use in the other human simulation departments where this is currently lacking. (Less)

Sensor with improved voltage protection

Abstract: A radar level gauge using microwaves for measuring a level of a surface of a product in a container, comprising a two-wire interface for connecting said measurement circuitry externally of said radar level gauge. A voltage protection circuitry connected between the two lines of the two-wire interface, the voltage protection circuitry including a transistor having an input, an output and a control terminal, a voltage regulator component connected between the output and the control terminal in such a way that the regulating characteristics of the voltage regulator component determines the voltage required to open the transistor, and a resistor connected between the control terminal and the input of the transistor.
