The invention discloses a double-cylinder air cooling silent diesel power generator set which comprises a body. A pulling mechanism is fixedly connected to the left side of the top of the body. A cover plate is arranged on the left side of the body. A clamping mechanism is fixedly connected to the bottom of the cover plate. According to the diesel power generator set, by means of cooperative use of the body, the pulling mechanism, a third fixing rod, a third sliding rod, a lifting rod, a first stop block, the cover plate, the clamping mechanism, a second clamping block, a fourth fixing block,a first clamping groove, a clamping box, a first fixing rod, a first sliding rod, a first fixing block, a transmission rod, a second fixing block, a second fixing rod, a second sliding rod, a first clamping block and a third fixing block, the problems that when an existing double-cylinder air cooling silent diesel power generator set is repaired or maintained, the disassembling process of the cover plate is tedious, and as a result, a user cannot use the power generator set conveniently are solved. The double-cylinder air cooling silent diesel power generator set has the advantage of being convenient to disassemble, and practicality of the double-cylinder air cooling silent diesel power generator set is improved.
