Benefits and Features

- Tough and durable, with field-proven head design - When configured with customer-supplied air fuel ratio control and three-way catalyst, the engine is capable of meeting NSPS and non-attainment area emissions levels. - Integrated operator interface panel reduces hands-on time with the engine - Operator interface panel allows setup and servicing without a laptop - Runs on a broad range of fuels and speeds at any emissions level - Factory-installed components with single connection point eases packaging

The ADEM A4 system represents the next generation of engine management systems while reducing the number of mechanical components and easing troubleshooting. Features include: • Electronic ignition • Electronic governing/speed control • Start/stop logic • Engine protection and monitoring

Large variety of factory-installed engine attachments reduces packaging time
