Problems solved by technology

Therefore, in order to be able to run stably without stalling when the traditional engine is idling, it is necessary to increase its idle speed, which will virtually increase the fuel consumption of the engine and reduce the economy.

Abstract

The invention discloses an inertia variable engine. The inertia variable engine comprises an engine and a flywheel. A crankshaft of the engine is fixedly connected with the flywheel directly or by a variable speed gear, the flywheel is connected with an inertia body by a mechanical engaging and disengaging gear or an electromagnetic engaging and disengaging gear, the inertia body is a rotary structure with a certain inertia, and the variable speed gear or a control device of the mechanical engaging and disengaging gear or the electromagnetic engaging and disengaging gear is linked with an engine throttle. Idle speed of the engine is reduced by changing moment of inertia of the engine flywheel. The inertia variable engine has simple structure, reliable operation and good environmental protection performance and saves fuel.

Description

technical field [0001] The invention relates to the field of engines. Background technique [0002] The "idling speed" of the engine refers to the minimum speed at which the engine is not connected to the external load and only maintains the normal operation of the engine without external work. When the engine maintains its own operation at a lower speed, it generally only needs the engine to emit less than 10% of the usual rated power, and the speed is about 20% of the rated speed. At this time, the speed and combustion volume of the engine are not in the best state in the original design of the engine, the state of fuel supply and ignition is on the verge of being stable and stopped, and the flywheel of the engine does not have enough inertia at this time. A little bit of air leakage, lack of oil, misfire or load change can no longer maintain this low-speed operation. Therefore, in order to be able to operate stably without stalling when the traditional engine is idling,...
