Portable generators provide electricity by running a gas-powered engine that turns an on-board alternator to generate electrical power. Power outlets on the unit allow you to plug extension cords, electric-powered tools and appliances into it.

The muffler, also known as a silencer, is designed to reduce the noise generated by the exhaust gases. It incorporates sound-absorbing materials and baffle chambers to dampen the sound waves, resulting in the quieter operation of any silent portable diesel generator.
