Abstract: An electrical system to provide a continuous source of energy AC/DC within a vehicle. This system charges the batteries thus exerting a natural braking effect on the motor at those times when it is desired to slow the forward motion of the vehicle such as when going down hill or needing to come to a stop. Due to the batteries being thus intermittently charged, somewhat smaller batteries may be used than are used in the prior art, and the recharging interval can be lengthened. The system is environmentally friendly, with zero emissions and is economical to operate. In addition, the vehicle is quiet and gives a smooth ride.

Abstract: An air filter assembly for a heavy duty motor vehicle generator is disclosed. The assembly includes an adaptor plate and connecting means for rigidly connecting the adaptor plate to one end of the generator. The assembly further includes a housing enclosing a chamber and an air filter element removably disposed in the chamber, the housing having a circular threaded collar threadably engaged to the adaptor plate. Through the air filter element, and apertures provided in the housing and adaptor plate cooling air flow is permitted to flow but particulate foreign matter is excluded.
