Abstract:
Es wird ein Vergaser mit einem Anschlüsse (2, 4) einerseits für einen Luftstrom und anderseits für flüssigen Brennstoff besitzenden Gehäuse (1 ), das einen offenporigen Strömungskörper (5) zur Leitung des Luftstroms und des Brennstoffs umschließt, und mit einer Verteilereinrichtung für den Brennstoff beschrieben. Um eine vorteilhafte Verdampfung des Brennstoffs im Luftstrom zu ermöglichen, wird vorgeschlagen, dass die Poren des Strömungskörpers (5) die ausschließlichen Strömungswege sowohl für den ihn durchströmenden Luftstrom als auch für den Brennstoff bilden und dass der Strömungskörper (5) einen an den Anschluss (4) für den Brennstoff angeschlossenen, flüssigkeitsdurchlässigen Mantel (6) als Verteilereinrichtung für den Brennstoff aufweist.
Abstract:
Изобретение относится к двигателестроению, в частности к способам и устройствам для приготовления топливовоздушной смеси и подачи ее в двигатель внутреннего сгорания. Способ приготовления топливовоздушной смеси включает в себя регулирование смеси в карбюраторе перед подачей в камеру сгорания. Полное смешивание всего объема воздуха, поступающего от воздушного фильтра и топлива, подвергают в дополнительной герметичной поплавковой камере с предохранительным клапаном, имеющей два входа и один выход, путем холодного кипения, испарения и гомогенизации топливовоздушной смеси. Устройство снабжено дополнительной герметичной поплавковой камерой с предохранительным клапаном. Дополнительная поплавковая камера разделена перегородкой на два объема. В первом объеме установлен поплавковый узел с запорной иглой, второй объем заполнен металлической сеткой. Перед выходом смеси установлена нерегулируемая заслонка с нагревательным электрическим элементом перпендикулярно потоку топливовоздушной смеси. Изобретение позволяет повысить эффективность сгорания топливовоздушной смеси.
Abstract:
A fuel system for use in an internal combustion engine includes a plurality of fuel injectors, each injector including at least one capillary flow passage, the at least one capillary flow passage having an inlet end and an outlet end, a heat source arranged along the at least one capillary flow passage, the heat source operable to heat a liquid fuel in the at least one capillary flow passage to a level sufficient to convert at least a portion thereof from the liquid state to a vapor state, and a valve for metering fuel to the internal combustion engine, a controller to control the power supplied to the heat source of each of the plurality of fuel injectors to achieve a predetermined target temperature, a sensor for use in determining engine air flow and a sensor for measuring a value indicative of degree of engine warm-up of the internal combustion engine. According to a further aspect of the present invention, an initial liquid fuel pulse is purged from the fuel injector while the intake valve is in a substantially closed position so as to further minimize hydrocarbon emissions at startup.

In another embodiment, a heater (510) includes a first heater sub-assembly (519), a second heater sub-assembly (719), an access panel (511) coupled to an intake (512), and a retainer mechanism (515) coupling the first heater sub-assembly and the second heater sub-assembly to the access panel.
Abstract:
The present invention pertains to the field of engine construction and may be used in the inlet systems of internal combustion engines for processing a portion of the rich air-fuel mixture fed into the main flow, wherein the liquid fuel is pulverised and converted into gas. The purpose of this invention is to increase fuel savings, to reduce the exhaust gas toxicity and to enable the use of a cheaper low-octane fuel. The method for preparing the air-fuel mixture comprises using the heat from the hot gases produced for heating the excessively rich mixture flow that contains between 10 and 100 % of petrol to be used by the engine, wherein said heating is carried out before mixing the mixture with the second flow. The mixture is then submitted in one or more steps to the thermal action of activators with compensation for the air used during the reactions. The device of the present invention comprises a heat exchanger (1) as well as a unit for dosing the mixture components (2), wherein said unit is connected by an inlet duct (5) to the mixture circuit through which said mixture is fed into a chamber (3) with an activator (4). The hot gases are generated in this chamber and flow through the inlet duct (6) of the gas circuit as well as through the outlet duct (7) thereof into the engine inlet system. The activator (4) chamber is connected to a pipe (8) and to a plurality of nozzles (9) for supplying additional air to the activator. The heat exchanger includes a body having an embossed partition therein that defines a plurality of cells-channels for the flow of the heat-carrier and the heating medium, wherein the walls of each cell-channel are connected together at their end portion up to half the height of the channel.
