Multiple-frequency inversion method and control apparatus for internal combustion engine driven generator
A multiple-frequency inversion method and a control apparatus for an internal combustion engine driven generator includes an inverter unit that employs a multiple-frequency inversion technology, controlling the inverter unit through a low switching frequency f to obtain a 2f modulated frequency, thus resolving the problem that a low frequency switching component generates a high frequency modulated waveform. Four switching devices in the inverter unit have the same working frequency, alleviating the controller load. In addition, a high modulated frequency reduces the device parameters of the filter unit, resulting in a smaller-sized and lighter apparatus, thus giving the generator portability. Reduction of the device parameters of the filter unit means reduction of the output internal resistance of the generator, therefore increasing the non-linear load capability of the generator.

OIL PRESSURE LIMITING DEVICE AND INTERNAL COMBUSTION ENGINE INCLUDING THE SAME
Disclosed is an oil pressure limiting device including a crankcase (20) and an oil pump chamber (10) communicated with the crankcase (20). The oil pump chamber (10) in which an oil pump is arranged has an oil inlet path (12), an oil outlet path (13) and an oil return path (14), wherein, the oil outlet path (13) is communicated with a main oil passage (21) in the crankcase (20). An oil return chamber (22) communicated with the oil return path (14) is arranged in the crankcase (20). The first end of the oil return chamber (22) is communicated with the main oil passage (21) by a flow limiting component. Also disclosed is an internal combustion engine including the oil pressure limiting device. The oil pressure limiting device with simple and practical structure enables the oil pressure in the main oil passage to be controlled, the power consumption of the oil pump to be reduced, and the high-pressure oil to be prevented from directly returning into the crankcase to generate foam in the oil, and thus ensures the lubrication effect.
A piston connecting rod structure comprises a piston (10) and a connecting rod (20). The connecting rod small end (21) of the connecting rod (20) is hinged with the piston (10) through a pin shaft. Two end faces of the connecting rod small end (21), along the axial direction of a connecting rod pin shaft hole (30), form a contraction structure which contracts towards the top of the piston (10). The piston (10) has a mounting groove (11) matched with the contraction structure of the connecting rod small end (21). The connecting rod small end (21) of the piston connecting rod structure adopts a wedge-shaped structure, so as to realize the reduction of the reciprocating inertia force of the connecting rod (20) by subtracting the redundant mass of the connecting rod (20) and meet the requirement of the strength and rigidity of the piston connecting rod at the same time.
Disclosed is a cylinder head valve arrangement structure of an air-cooled diesel engine. An intake passage (10) and an exhaust passage (11) formed in the cylinder head (2) are located on two opposite sides of the cylinder head (2), respectively, and the axial direction of the crankshaft (1) is the same as the intake/exhaust direction of the cylinder head (2). An intake valve (15) and an exhaust valve (14) are provided on the intake passage (10) and the exhaust passage (11), respectively. A line connecting the centers of the intake valve (15) and the exhaust valve (14) is obliquely staggered with respect to the axial direction of the crankshaft (1) to form an included angle (α). A first cooling air passage (8) formed in the cylinder head (2) extends through the entity of the cylinder head along above mentioned intake/exhaust direction, and passes out from between the intake valve (15) and the exhaust valve (14). Also disclosed is an air-cooled diesel engine including the valve arrangement structure. The air-cooled diesel engine enables the peripheries of both the intake valve and the exhaust valve to be effectively cooled, so that the entire cooling effect of the cylinder head is improved, the uniform movements of the intake valve and the exhaust valve are ensured, and the performance of the diesel engine is improved.
