Abstract:
A fuel injector adapter for providing nitrous oxide to an internal combustion engine is disclosed. The nozzle has a fuel injector passage, having a central axis and terminating at an injector outlet, for passing fuel from a fuel injector to an engine. The nozzle also has one or more first auxiliary passages, which may be arranged in an annular pattern around the fuel injector passage, and which terminate at first outlets. The nozzle furthermore may have one or more second auxiliary passages, which also may be arranged in an annular pattern around the fuel injector passage, and which terminate at second outlets. The first auxiliary passages and second auxiliary passages are adapted to supply nitrous oxide or other additional combustion reactants to the engine. The nozzle may be attached to an engine intake and may be adapted to fit between a fuel injector and an engine without substantial modification to the engine.
Abstract:
The present invention relates to a modified intake manifold having short runner valves in the manifold tuning valve. Anti-chatter devices are disclosed for reducing shaft chatter without placing friction on the shafts. A lost motion linkage is used to ensure closure of the short runner valves. Radiused seating surfaces are used for seating of the manifold tuning valve.
Abstract:
A surge tank structure in an intake manifold has a serge tank to which a plurality of branch tubes are joined at one end. The branch tubes are joined at the other end to a cylinder head mounting flange, and one end of each branch tube in the surge tank is enlarged to have a horn-like shape. The serge tank comprises a main body and a top plate. The main body has through holes provided therein for accepting the branch tubes and has its top side opened. The top plate is joined in a plane to the top of the main body. The main body has a bottom which has engagement recesses formed by raised portions, so that each engagement recess has a horn-like surface that conforms to the horn-like shape of one end of each branch tube.
Abstract:
A core for producing a molded resin product having a bent hollow portion, including two-forked and multi-forked products used as parts for automobiles, and a process for producing the aforesaid resin product having a bent hollow portion by using said core.
Abstract:
Die Erfindung betrifft einen flexiblen Schlauch, vorzugsweise Ladeluftschlauch für die Automobilindustrie. Ladeluftschläuche mit starren und flexiblen Abschnitten sind bekannt. Der Erfindung liegt die Aufgabe zugrunde, einen Schlauch, insbesondere Ladeluftschlauch mit starren und flexiblen Abschnitten bereitzustellen, der kostengünstiger herstellbar und gegenüber Materialversagen bei Dauergebrauch weniger anfällig ist als ein herkömmlicher Schlauch. Zur Lösung dieser Aufgabe stellt die Erfindung einen flexiblen Schlauch bereit, umfassend zumindest ein vernetzbares Material, wobei der Schlauch bereichsweise unterschiedliche Vernetzungsgrade aufweist.
Abstract:
The invention refers to an intake manifold (10) for supplying air and exhaust recirculation gas (EGR) to an internal combustion engine (12), the cast manifold (10) comprising:
an air intake port (24); an intake chamber (40) receiving intake air from the intake port (24); an outlet plenum (42) communicated with the engine (12); an EGR inlet port; an EGR outlet passage (68) communicating the EGR inlet port with the plenum (42); a wall (90) separating the intake chamber from the EGR outlet passage, said wall creating turbulence in the intake air as the EGR from the EGR outlet passage (68) mixes with intake air from the intake chamber (24).
Abstract:
An intake manifold comprising a plurality of intake pipes (3) connecting a collector to an intake pipe mounting part, wherein the intake pipes (3) bent in specified shapes, respectively, are formed by bending a generally straight metallic dual tube, set so that a clearance (3c) between an outside tube (3a) and an inside tube (3b) is 0.2 mm or less, to bring the outside tube (3a) into contact partially with the inside tube (3b) at its middle part, whereby each intake pipe (3) is structured so that the outside tube (3a) is brought into contact partially (slidably each other) with the inside tube (3b) at its middle part, and an air layer of approx. 0.2mm or less in thickness is formed between the outside tube (3a) and the inside tube (3b) in those areas other than a contact part (3e).
Abstract:
Bei diesem Verfahren wird in einem ersten Schritt ein tellerförmiger Grundkörper (1) aus einem metallischen Werkstoff hergestellt, der außen einen durchgehend ringförmigen Bereich (1a) aufweist und der zwischen dem ringförmigen Bereich (1a) und einem rohrförmigen Innenteil (1b) mindestens zwei Aussparungen (4) aufweist. In einem zweiten Schritt wird jeweils ein scheibenförmiges Teil (2) aus einem Kautschuk mit seinem Außenbereich (2a) auf jeweils einen umlaufenden Randbereich (1a'), der eine Aussparung (4) umgibt, auf die konvexe Außenseite des Grundkörpers (1) aufgelegt. Anschließend erfolgt in einem dritten Schritt die Verbindung des scheibenförmigen Teils (2) mit dem umlaufenden Randbereich (1a') durch Aufvulkanisieren.
