The Dorman SE range of engines is the world's most integrated engine range. Covering the power band 221 kWb-1879 kWb, the SE series offers a unique range of engines, 6 and 8 cylinder Vee form, with a common design concept. The range features include exceptional power to weight ratios, commonality of components, low fuel and oil consumptions, low levels of gaseous emissions and levels of overall performance and reliability that set new standards for the design of diesel engines.
The SE series is unique in offering such high performance and reliability in a single range of premium specification engines with a common design concept. Proven in the most arduous conditions worldwide, the SE series is a major milestone in the development of the diesel engine.
High power to weight ratio
The Dorman SE series engines are noted for achieving high power outputs per cylinder and offering high power to weight ratios. In practice, these engines provide power outputs normally only associated with much larger engines, their compact size and low weight reduces shipping costs and allows for easier installation. As the number of cylinders for the output is lower than other engine designs, the SE offers considerably reduced maintenance downtime and lower parts costs for the power levels required.
Ease of servicing
Part of the initial design brief for the SE series was excellent service access and ease of maintenance. The individual cylinder heads can, for example, be easily removed. The unit fuel injection system considerably aids reliability and maintains overall engine efficiency whilst providing an easily serviced system without high pressure fuel pipes and pumps. Attention to detail has created an engine design with high availability and low down time. The SE series benefits from the worldwide support of the Dorman international dealer network, sophisticated parts support system and the finest trained engineers. These facilities, available in over 100 countries, provide a back-up to Dorman products that few can match. In addition, all SE customers receive the considerable benefits of the Dorman Red Seal extended guarantee scheme. The Red Seal Guarantee is a major statement of confidence by Dorman in their engines and full details are available on request.
For over a century Dorman customers have repeatedly chosen Dorman, not just because of excellent products but because they appreciate the blend of quality, reliability and total commitment to meeting the needs of customers that is synonymous with the Dorman name.
The first SE series engines were launched in 1984 and have operated successfully in the widest possible range of applications and climatic conditions, literally from Greenland to the deserts of Arabia. The range has been subject to continued research and development using the latest techniques of diesel engine design and engineering practice and are manufactured to the highest quality standards.
At an early stage, advanced computer predictive techniques and finite element analysis were extensively used. Application of such advanced engineering techniques allowed Dorman engineers to optimise component design, to achieve maximum reliability and component life and thereby further contribute to operating efficiency.
Later in the development programme, specially constructed test chambers at the Dorman factory allowed each stage of design and development of each engine to be fully tested in rigorous operating conditions, allowing years of simulated usage to be incorporated in basic design decisions. The application of techniques such as photo elastic strain analysis contributed significantly to the success of the development programme.
The resulting proven engine range is available in a wide range of turbocharging and cooling combinations to suit the application, and specific marine versions, the Dorman Sea King Series, are also available. In addition to these diesel fueled units, a complementary series of SE gas fueled engines are available to run on a wide range of natural, bio and landfill gases.
All engines are extensively test run and approved before leaving the Dorman factory and each engine is individually certified as complying with Dorman quality standards. As Dorman engines are extensively test run before dispatch, they can be they can be directly installed on site and will give full power on installation, without a period of 'bedding-in'.
In their industrial format the SE range of engines are designed to operate continuously at speeds of 1000-1800 rpm. The engines are built in a factory approved to UK MOD standards, in addition to BS 5750/ISO 9000. All engines are tested to comply with BS 5514/1-1982, ISO 3046/1.
The specific performance of each engine is detailed in the tables and more specific performance figures related to application are available on application to the Dorman sales department.
Emission levels are low, typical smoke levels of below 1 Bosch unit being achieved. Coupled with their overall compact size, high power output and low fuel consumption, the SE series is an exceptional engine range.
Electronic governing is fitted as standard with the option of hydraulic governing available to suit the engines for any specific application. The engines have electric start as standard, with air or hydraulic starting available as options as appropriate for the application. Crank case doors are fitted as standard.
Applications typically include: Generating sets, pump sets, compressor sets, excavators, cranes, off-highway earth moving equipment, stone crushers and locomotives.
