Detailed Description
The invention is further described with reference to the following examples and accompanying drawings.
An efficient energy-saving low-noise internal combustion engine generator comprises a crank connecting rod mechanism and a generating set;
the crank connecting rod mechanism comprises a cylinder body 1, a cylinder sleeve 2, a piston 3, a connecting rod 4, a crankshaft 5 and a flywheel 8;
the power generation device comprises a sliding pin 6, a sliding rack push rod 7, a guide sliding pin 9, a generator shell 10, a sector gear 11 and a generator 12;
the crank connecting rod mechanism formed by the high-efficiency energy-saving low-noise internal combustion engine generator, the cylinder body 1, the cylinder sleeve 2, the piston 3, the crankshaft 5 and the flywheel 8 is a conventional engine mechanism;
when the connecting rod 4 reciprocates, the sliding pin 6 pushes the sliding rack push rod 7 to reciprocate, and the other sliding groove on the sliding rack push rod 7 is in sliding fit with the guide sliding pin 9 to ensure the reciprocating motion of the sliding rack push rod 7;
the rack on the sliding rack push rod 7 is meshed with the sector gear 11, the sector gear 11 is pushed to rotate in a reciprocating mode by the reciprocating motion of the sliding rack push rod 7, the sector gear 11 is fixedly connected with the rotor of the generator 12 to rotate concentrically, and the rotor of the generator 12 is driven to rotate in a reciprocating mode by the reciprocating rotation of the sector gear 11, so that electric power output is generated;
when the piston starts to do work after passing through a top dead center, the top thrust of the piston 3 is transmitted to the crankshaft 5 and the sliding pin 6 through the connecting rod 4, the crankshaft 5 drives the flywheel 8 to rotate, the power output end of the crankshaft keeps unpowered output, and the engine is in an idle motion state; meanwhile, the sliding pin 6 pushes the sliding rack push rod 7 to move, a normal acting force is generated between the sliding pin 6 and the sliding groove of the sliding rack push rod 7, the normal acting force is overcome by the combustion thrust at the top of the piston 3 through the connecting rod 4, if the friction between each kinematic pair is neglected, the motion direction of the piston 3 is equal to that of the piston 3 directly pushing the sliding rack push rod 7, therefore, the work done by the combustion at the top of the piston 3 is efficiently transmitted to the sliding rack push rod 7, and then the generator 12 is driven to generate electricity through the efficient meshing transmission of the sliding rack push rod 7 and the sector gear 11, the problems of larger noise, vibration and low energy utilization rate caused by smaller transmission angles of the connecting rod 4 and the crank 5 when the traditional crank-connecting rod mechanism burns and does work after the top dead point of the piston 3 are overcome, although the transmission angles of the connecting rod 4 and the crank 5 are gradually increased after the piston 3 passes the dead point, the work done by the combustion at the top of the piston 3 is also gradually reduced, therefore, the performance of the traditional internal combustion engine is poor, and particularly the energy utilization rate is low.
Because the structure of the original engine is unchanged, but the original engine does not have power output, which is equivalent to idle running, the continuous work of each stroke is ensured under the cooperation of the flywheel 8, and the engine has smaller power consumption and low noise during idle running;
the acting force directions of the motion pairs of the rod pieces are reasonable in a transmission system from the piston 3 to the generator 12 and are efficient transmission pairs, work done by the piston 3 is mainly directly used for power generation through the efficient transmission system, the energy utilization rate of an engine is obviously improved, and noise and vibration of the engine are reduced.
