Gen 5 DD Platform Operators Manual Forward Introduction This manual is intended to be used by the operator of Detroit™ Gen 5 Heavy Duty engines. The manual covers basic information on engine components, engine operation, Detroit Diesel Electronic Controls (DDEC®) system, engine systems, aftertreatment system, instrument panel indicators, preventative maintenance, how to procedures, and customer assistance. Electronic engine controls have been instrumental in aiding engine manufacturers meet federal emission requirements and the ever-increasing performance demands of the customer.
Non-Genuine and Rebuilt Component Quality Alert Maintenance procedures must be followed in order to continue satisfactory performance and durability and to ensure coverage of the engine under the manufacturer's warranty. Many of these maintenance procedures also ensure that the engine continues to comply with applicable emissions standards. Proper maintenance procedures, using specific components engineered to comply with emissions regulations, may be performed by an authorized Detroit™ service outlet, an independent outlet, or the operator or owner.
The owner is responsible for determining the suitability of components to maintain emissions compliance during the engine's useful emission life. Detroit™ cautions that the indiscriminate rebuilding of precision components, without the benefit of specifications, specialized equipment, and knowledge of the electronic operating system, will jeopardize performance or lead to more serious problems, and can take the engine outside of emission standards compliance.
There are several other components in an engine, including but not limited to the turbocharger, fuel injectors, camshaft s, pistons, diesel exhaust fluid pump, which are specifically designed and manufactured to exacting standards for emissions compliance. It is important that these components, if replaced, modified or substituted, can be verified thus ensuring that the engine remains in compliance with emissions standards. The use of inadequately engineered, manufactured or tested components in the repair or rebuild of the engine may be in violation of federal regulations.
Furthermore, modern engines exhibit operating parameters which require the use of proper fluids, such as fuel, coolant and lubricating oil, to maintain long engine life. The use of fluids that do not meet Detroit™ specifications may result in premature wear or engine failure.
