C7 ACERT™ Water-Cooled Manifold Engine
THE RUNDOWN
Technology
- Electrical harness containing point-to-point wiring without splices in any power/signal wires - Electrical harnesses and connectors are overmolded and are routed through urethane tube for protection against impact and vertical flame propagation. - To meet safety requirements, connectors require the use of a special tool to be disconnected and bear the “do not disconnect while energized” warning. - Optional ATEX and NEC certified 25-foot customer harness - ECU is certified as part of the engine to restricted breathing per EN 60079-15. ECU is protected with a stainless steel guard. - Fuel injector connections at valve cover bases are protected with stainless steel guards
Advanced Digital Engine Management
ADEM A4 engine management system integrates speed control, air/fuel ratio control and ignition/detonation controls into a complete engine management system. control system with integrated digital ignition, engine protection and monitoring
Air System
- Separate circuit (water-to-air) aftercooler options available to match any application requirement. - Water-cooled exhaust manifold and turbo maintain ATEXcompliant skin temperature during operation
Improved Serviceability
- Front, right, and rear dipsticks - Remote oil and fuel filters - 12V and 24V electronic systems to improve application flexibility
