SERIES 60 ON-HIGHWAY ENGINE OPERATOR'S GUIDE INTRODUCTION This guide is intended for use by the operator of a Detroit Diesel Series 60® engine used in the following applications: specific components engineered to comply with emissions regulations, may be performed by an authorized Detroit Diesel distributor or dealer, 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.
On-Highway Vehicles Fire Truck or Crash/Rescue Vehicles Non-Genuine and Rebuilt Component Quality Alert Electronic controls and components have significantly increased in sophistication, but the fundamental objective remains the same — precise timing and delivery of fuel. The very heart of the Detroit Diesel Electronic Controls (DDEC®) is the electronic unit injector (EUI). The proper functioning of the EUI is absolutely paramount if the benefits of electronic controls are to be realized. Detroit Diesel Corporation has built over 650,000 engines with electronic unit injectors — more than anyone else in the business.
In recent years, electronic engine controls have been instrumental in aiding engine manufacturers in meeting the stringent emission requirements of the U.S. Environmental Protection Agency (U.S. EPA) and the California Air Resources Board (CARB) and also in meeting the ever-increasing performance demands of the customer. Maintenance procedures are to 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. The U.S.
EPA specifically defines an engine's “useful emission life” currently established as 435,000 miles (700,000 kilometers) for on-highway engines. Proper maintenance procedures, using Detroit Diesel 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 compliance with U.S. EPA or CARB emissions standards.
