摘要:
The invention refers to a drive system including an engine having a pressurizable fuel rail in fluid communication with the pressurizable fuel rail and at least one fuel injector for direct injection into at least one combustion chamber of a respective cylinder, a fuel tank, a fuel pump for conveying liquid fuel from the fuel tank for liquid fuel through a conduit to an evaporation device for transferring the fuel from a liquid to a gaseous state, a conduit for conveying the evaporated fuel to the fuel rail, an electromagnetic manometer for measuring the pressure in the fuel rail and for providing a control signal to the fuel pump, and an emergency valve functionally connected to the fuel rail to control an upper pressure limit in the fuel rail wherein the evaporation device comprises a heating chamber having a heating source and the at least one fuel injector is designed to inject fuel in the gaseous state directly into the combustion chamber of the respective cylinder. The invention also refers to a corresponding vehicle and the use of a kit in such a drive system.
摘要:
The system is applied to an engine (M) having an injection system, a fuel feed line and a cooling system (CS), by means of a cooling fluid which circulates, through hot fluid ducts and cold fluid ducts, through the engine (M) and through a heat exchanger. The feed line has a first segment, connected to the injection system and provided with a first valve, to be closed when the fuel temperature is below a maximum value, and open when the fuel temperature reaches the maximum value. The feed line also has a second segment derived from the first and absorbing thermal energy from the hot fluid duct or from the combustion gases and provided with a second valve which remains open while the fuel temperature is lower than the maximum value, and which is closed when said temperature reaches the maximum value.

Um ein Motorarbeitsgerät (100) wie eine Kettensäge, ein Handschleifgerät, eine Handkreissäge, ein Rasenmäher, ein Rasentrimmer oder ein sonstiges Handwerkzeug oder Gerät zur Garten- und Landschaftspflege, aufweisend einen Verbrennungsmotor (10) mit wenigstens einem Zylinder (11) und wenigstens einem Vergaser (12), der in einem Vergaserraum (13) angeordnet ist, der durch eine Zwischenwand (14) von einem Motorraum (15) getrennt ist, wobei ein Lüfterrad (16) vorgesehen ist, durch das Luft aus dem Motorraum (15) durch eine Motorraumöffnung (17) in der Zwischenwand (14) in den Vergaserraum (13) einbringbar ist, zu schaffen, insbesondere ein Element zum Umschalten des Sommer-Winter-Betriebes weiter zu vereinfachen, wird vorgeschlagen, dass zusätzlich zur Motorraumöffnung (17) eine Warmluftöffnung (18) in der Zwischenwand (14) vorgesehen ist, durch die über den Zylinder (11) erwärmte Luft in den Vergaserraum (13) einbringbar ist, und wobei ein Stellelement (19) vorgesehen ist, das in eine Sommerstellung bringbar ist, in der die Motorraumöffnung (17) geöffnet und die Warmluftöffnung (18) geschlossen ist und das in eine Winterstellung bringbar ist, in der die Motorraumöffnung (17) geschlossen und die Warmluftöffnung (18) geöffnet ist.
摘要:
Apparatus, and method, for conditioning air and fuel supplied to a combustor comprising means (5) for electrostatically charging air supplied to a combustor at a first polarity, means (12) for electrostatically charging fuel supplied to such combustor at opposite polarity to said first polarity, and means (15, 19; 20) for preheating such fuel.
摘要:
A fuel delivery system is disclosed which includes an injector (40) having an end region (43). The end region (43) is provided from heat conducting material such as metal so that the end region can be heated by exhaust gas to heat the temperature of fuel in the injector end region so that the increase in temperature and pressure within the end region causes the fuel to flash into a vapour state immediately the fuel is ejected from the injector. The exhaust gas is supplied by an exhaust gas supply line (70, 402) and can be returned by an exhaust return line (405).
摘要:
A hollow-cylindrical heat conduction portion (44) is formed on a throttle body (42) in such a way as to protrude outwardly therefrom in the radial direction. The throttle body (42) and the heat conduction portion (44) are integrally formed using metal material such as aluminum having excellent heat conductivity or resin material containing such a metal material. A vent hole (31) communicating the interior with the exterior of a head cover (3) is formed in the head cover (3). Through the vent hole (31) there is inserted the heat conduction portion (44), and the clearance between an outer-peripheral wall thereof and an inner wall of the vent hole (31) is sealed by means of a seal member.
