Abstract: Es wird ein Zweitakt-Verbrennungsmotor mit zwei an einen gemeinsamen Resonanzauspuff angeschlossenen Zylindern (1) beschrieben, deren Kolben (3) an um 80° gegeneinander winkelversetzten Kurbelzapfen (5) angreifen. Um einen vorteilhaften Massenausgleich erster Ordnung zu erreichen, wird vorgeschlagen, dass die beiden Zylinder (1) in einer gemeinsamen Ebene angeordnete, miteinander einen rechten Winkel einschließende Achsen (2) aufweisen, dass die Kolben (3) der beiden Zylinder (1) an Kurbelzapfen (5) zweier gesonderter Kurbelwellen (6) angreifen, denen eine parallele Ausgleichswelle (13) zugeordnet ist, die durch den Schnittpunkt der Zylinderachsen (2) verläuft und mit gleicher Drehzahl wie die Kurbelwellen (6), aber gegensinnig dazu antreibbar ist, und dass die Ausgleichswelle (13) eine mit den Ausgleichsmassen (17) der Kurbelwellen (6) zusammenwirkende Ausgleichsmasse (16) für den Ausgleich der Massenkräfte und Massenmomente erster Ordnung umfasst.

Abstract: A two-stroke internal combustion heat engine (1) with fuel direct injection, wherein the heat engine (1) has: at least one cylinder (2) with an internal combustion chamber (7) having a cylindrical symmetry around a first longitudinal axis (Al); a piston (8) mounted inside the cylinder (2) to slide in a reciprocating manner; a cylinder head (11) closing the combustion chamber (7) at the top; a spark plug (12) mounted through the head (11) and having a pair of electrodes (13) at the bottom; and an injector (14), which is arranged through the side wall of the cylinder (2), has a second longitudinal axis (A2) and is provided with an injection nozzle (15). The injection nozzle (15) of the injector (14) faces the head (11) to spray fuel towards the cylinder head (11), and the second longitudinal axis (A2) is inclined to form an acute angle with the first longitudinal axis (Al).

Abstract: A crankcase (100) for an engine includes a first bank (102) of cylinders that has a plurality of cylinder bores (104) formed therein, and a second bank (102) of cylinders that includes an additional plurality of cylinder bores (104). The second bank (102) is at an angle with respect to the first bank (102). A valley structure (106) is located between the first bank (102) and the second bank (102). A gallery (122) is located between the first bank (102), the second bank (102), and the valley structure (106). The gallery (122) has at least one rear opening (118) that fluidly connects the gallery (102) to a rear portion (120) of the crankcase. At least one front opening (210) fluidly connects the gallery (122) to a front portion (116) of the crankcase (100). At least one breather opening (124) fluidly connects the gallery (122) to an outer valley surface (107).
