Description
Die Erfindung betrifft eine Einrichtung zum Vorwärmen der Ansaugluft beim Starten eines Ottomotors, vorzugsweise mit Direkteinspritzung gemäß dem Oberbegriff des Hauptanspruches.The The invention relates to a device for preheating the intake air when starting a gasoline engine, preferably with direct injection according to the preamble of the main claim.
Vorbekannt
ist es, bei Diesel- und Ottomotoren Vorwärmeinrichtungen im Saugrohr
für den
Startvorgang vorzusehen. Derartige Einrichtungen sind vorzugsweise
als flächenförmige, im
Ansaugkanal angeordnete, elektrische Heizelemente aufgeführt und
dienen bei Ottomotoren mit Saugrohreinspritzung als Verdampfungsflächen für vor dem
Ansaugventil durch eine Einspritzdüse in den Ansaugkanal eingebrachten
Kraftstoff. Der
Es ist Aufgabe der Erfindung, eine Einrichtung zum Vorwärmen der Ansaugluft beim Starten eines Ottomotors vorzugsweise mit Direkteinspritzung zu schaffen, so daß ein williges Anspringen mit beschränktem Schadstoffausschuß erzielt wird.It The object of the invention is a device for preheating the Intake air when starting a gasoline engine preferably with direct injection too create, so that one willing leap with limited Pollutant Committee achieved becomes.
Erfindungsgemäß wird diese Aufgabe durch die im Hauptanspruch genannten Mittel gelöst.According to the invention this Problem solved by the means mentioned in the main claim.
Die Gestaltungsmerkmale der Unteransprüche werden in der nachfolgenden Beschreibung zusammen mit ihren Vorteilen erläutert.The Design features of the subclaims are in the following Description along with its advantages explained.
