One approach to providing atomic oxygen for the purpose of promoting more rapid and compact combustion is to disperse a low concentration of an atomic oxygen precursor, such as nitrous oxide (N2O), into the compressed air in the cylinder before or close to the time of ignition. The introduction of N2O may take place in the intake manifold, directly into the combustion chamber through a small orifice in the base of the fuel injector or a small nozzle located elsewhere in the cylinder head, or the N2O can be added as a solute to the injected fuel.

A power tool includes a tool head having a working element and a powerhead configured to provide power to the working element. The powerhead includes a fluid tank configured to hold a combustible fuel and defines an initial internal volume having an internal pressure. A diaphragm is formed of a flexible material and forms at least a portion of the fluid tank. The diaphragm moves from an unexpanded state to an expanded state when a temperature of the combustible fuel increases above a threshold value. Movement of the diaphragm to the expanded state increases the internal volume of the fluid tank to allow the internal pressure of the fluid tank to remain approximately constant.

COMMON-RAIL INJECTION DEVICE AND METHOD OF INJECTING A PREDETERMINED VOLUME OF FUEL

Номер: US20170321641A1
Автор: Durst Franz, Han Yu, RATLAMWALA Hussain Abdul Hussain
Принадлежит:

When fuel injections into Otto-engines are carried out, pressure pulsations occur in the entire fuel injection system. These prevent detailed information about the fuel injection to be deduced from the pressure signals measurable in the system. When specially designed dampers for these pressure pulsations are employed, pressure difference signals over the pulsation damper can readily be employed for instantaneous volume flow rate measurements. Furthermore, the inserted pressure pulsation dampers also allow the pressure reduction in the Common-Rail, due to the fuel injections, to be employed to measure the instantaneous fuel injection volume flow rates, in running Otto-engines. The authors' development work in this field is described in this paper and results of verification measurements are presented. 14.-. (canceled) The invention refers to a Common-Rail injection device as well as to a method of injecting a predetermined volume of fuel.To fulfill the more and more tight requirements of emission legislations and fuel economy needs, many new technologies have recently been developed to improve fuel direct injection systems for internal combustion engines. An important trend of the still ongoing R&D works is the precise control of the injected fuel quantity into the cylinders, as demanded by the engine load dependent combustion processes. In modern diesel injection systems, this is usually achieved by the selection of the injector, the start of the injection and the coordination of the injection pressure and the valve opening time. In this context, many new developments emerged in the last years, such as new magnetic/piezoelectric actuators with optimized opening and closing properties, optimization of the needle structure, and improvements of the injection orifice geometries, etc. In spite of this, the control of the fuel injection is still far from being perfect. Due to the rapid opening and closing of the injector valves, pressure pulsations are caused that ...
