Abstract: Bereitgestellt wird ein Ölversorgungssystem für einen Motor, das beinhaltet: eine Öldrucksteuerung bzw. Regelung zum Steuern bzw. Regeln einer Veränderungsverschiebungsölpumpe im Sinne einer Anpassung eines Abgabedrucks hiervon, um einen Sollöldruck entsprechend einem Betriebszustand des Motors zu erreichen, wobei die Veränderungsverschiebungsölpumpe dazu fähig ist, eine Abgabemenge von Öl anzupassen, einen Lastdetektor zum Detektieren einer Motorlast und einen Öltemperaturdetektor zum Detektieren einer Öltemperatur. Ist die Motorlast niedrig, so steuert bzw. regelt, um eine Menge eines Ölnebels, der innerhalb eines Kurbelgehäuses des Motors strömt, zu erhöhen, die Öldrucksteuerung bzw. Regelung die Veränderungsverschiebungsölpumpe im Sinne einer Erhöhung der Abgabemenge, wenn die Öltemperatur niedriger wird, wobei der Ölnebel von dem Öl, das aus einem Lagerteil strömt, das drehend wenigstens eine Kurbelwelle stützt, erzeugt und zerstäubt wird, wobei die Motorlast als niedrig betrachtet wird, wenn sie unter einer vorbestimmten Referenzlast ist.

Abstract: PURPOSE:To ameliorate the extent of fuel consumption by installing a compression type supercharger provided with an interval between elements themselves partitioning off an operating chamber, and when supercharging pressure by the supercharger is in a low supercharging area small in this supercharging pressure, controlling it so as to perform the fuel injection from a fuel injection valve. CONSTITUTION:An intake system 5 in an engine body 1 consists of a common intake passage 6, a surge tank 7 and an independent intake passage 9 leading to each inlet port 3, and in the common intake passage 6, there are provided a throttle valve 10, a supercharger 11 and an intercooler 12. On the other hand, a fuel feeding system is provided with a main fuel injection valve 15 and an auxiliary injection valve 16 installed just at the upstream side of the supercharger 11. Here the supercharger 11 is set down to what is called a Roots-type compression supercharger, say, such one that is provided with an interval between a tip of a cocoon-shaped rotor 19 and an inner circumferential surface 18a of a casing 18. An auxiliary fuel injection valve 16 is made to do its fuel injection at only the low supercharging area, and in a high supercharging area where the supercharger, is made into being hotted up, it is controlled so as not to do its fuel injection, through which any drop in charging efficiency with the carburetion of fuel is thus checked.

Abstract: PURPOSE:To reduce the intake noise generated by a supercharger effectively by making bypass passages provided to an intake passage exercise a function as a resonator to reduce the noise by the function of a resonator to the intake noise generated by the supercharger. CONSTITUTION:A Lysholm type supercharger 14 as a mechanical supercharger is provided at a collecting intake passage 10 at the upstream side from an intercooler 15. In a Vee-engine, two passages 20 and 21 are branched from a main passage connected to the intake side 14a of the supercharger 14, so as to bypass the supercharger 14 and the intercooler 15. And a bypass passage 22 is branched from a intake passage 10 at the immediate downstream of the discharge side 14b of the supercharger 14, so as to bypass the intercooler 15. And control valves 23 to 25 are provided on the way of the bypass passages 20 to 22 respectively, and the function as a resonator to the sound of a specific frequency is given to the bypass passages 20 to 22 by controlling the control valves 23 to 25.

Abstract: PROBLEM TO BE SOLVED: To optimally assist-restart depending on various operational statuses. SOLUTION: When an assist condition is satisfied and the state of a battery 80 is good, a starter motor 36 is driven (step S255), fuel is injected into a stopping time expansion stroke cylinder which is in the expansion stroke in automatic stop of an engine 1 after starting the restart of the engine 1 (step S257), and the engine 1 is restarted. On the other hand, when the assist condition is satisfied and the state of the battery 80 is deteriorated, the fuel is injected into the stopping time expansion stroke cylinder which is in the expansion stroke in the automatic stop of the engine 1 (step S2516), and the starter motor 36 is driven after the restart of the engine 1 (step S2517).
