Abstract
The utility model discloses a variable inertia engine which comprises an engine and a flywheel, wherein a crank shaft of the engine is directly and fixedly connected with the flywheel or is fixedly connected with the flywheel through a speed change device, the flywheel is connected with an inertia body by a mechanical or electromagnetic type clutch device, the inertia body is a rotating structural body with a certain inertia, and the speed change device or a control device of the mechanical or electromagnetic type clutch device is linked with a throttle of the engine. The utility model can reduce the idle speed of the engine by changing the rotating inertia of the engine flywheel and has the advantages of simple structure, reliable operation, fuel saving and good environment-friendly performance.
Description
Technical field
The utility model relates to engine art.
Background technique
" idling " of motor is that mean engine is not connecting extraneous load, just keeps the minimum speed that runs well when motor does not have externally acting.And motor is to keep self when running than the slow-speed of revolution, generally only needs motor to send less than rated power 10 at ordinary times, and rotating speed is 20 percent of rated speed approximately.At this moment the rotating speed of motor and burning capacity are not the optimum states in the original design of motor, the state of fuel feeding and igniting is in edge stable and that stop, engine flywheel seems that also inertia is not too enough this moment, at this time motor just can not continue to keep this more slow-revving running state again as long as a little gas leakage, oil starvation, catch fire or load variations.Therefore, be unlikely to flame-out for running that can be stable during the conventional engines idling, need its idling is heightened, so just increased the fuel consumption of motor virtually, Economy decline.And the desirable idling of motor should be to have the stable slow-speed of revolution, small oil consumption rate, and can open the throttle at any time enters high rotating speed running state.Just need the new work engine that rotating speed is lower, fuel efficiency is high under a kind of idling mode of invention for this reason.
Summary of the invention
In order to realize the purpose of motor slow-speed of revolution under idling mode, low fuel injection rate, the utility model discloses a kind of inertia variable engine, comprise: motor, flywheel, the bent axle of described motor directly or through speed change gear and described flywheel connects firmly, described flywheel is connected with the inertia body through mechanical type or electromagnetic type engaging and disengaging gear, described inertia body is the rotational structure body with certain inertia, the control gear of described speed change gear or described mechanical type or electromagnetic type engaging and disengaging gear and the throttle linkage of motor.
The utility model is to utilize engaging and disengaging gear that the inertia body is connected with flywheel or disconnect the variation that realizes flywheel inertia, or utilize speed change gear to realize the variation of Rotary Inertia of Flywheel by the rotating speed that changes flywheel, or adopt engaging and disengaging gear and speed change gear to reach to change the purpose of Rotary Inertia of Flywheel simultaneously, or be arranged on removable balancing weight on the inertia body realizes changing inertia body inertia to the distance of inertia body rotating center purpose by change.
The utility model mates its work requirements by the inertia of adjusting engine flywheel, can make motor that several operating modes are arranged, as high speed, middling speed, low speed and idling isotype.Turn inertia during high speed down, transfer big inertia during low speed.Motor can be worked under limit speed, and for example several commentaries on classics in a minute or a few minutes one change, and the fuel injection quantity of each burning is certain, and how promptly no matter load changes (how rotating speed changes), and the operating mode of in-cylinder combustion can be in best state.Because of the idling speed of motor has reduced, so the fuel injection rate in the cylinder also just descends thereupon, the oil spout total amount in the unit time has just reduced.Based on best combustion operating mode in the cylinder and the minimizing of oil spout total amount in the unit time, oil consumption and emission pollution problem that motor is under the idling mode also just are readily solved.
The utility model has following useful effect: simple in structure, reliable operation is saved fuel oil, good environmental protection.
