MTC installs Bosch EPS815 test bench for servicing

MTC, one of the fastest growing transport corporations in the country, recently installed the advanced diesel pump calibration machine, Bosch EPS815, to service its growing fleet of buses fitted with BS111 engines. This makes MTC the first transport corporation in India to invest on such a high technology machine. It has a fleet of over 3,000 buses, including more than 1,500 buses fitted with BS111 engines. The pumps fitted on these engines require high injection pressure for servicing.

The EPS815 is an advanced test bench used to check high-performance pumps for the newest generation and also common rail injectors from passenger cars to heavy commercial vehicles. It ensures that automobile manufacturers adhere strictly to emission norms.

The Bosch universal test bench is suitable for pumps up to 12 cylinders. As per the emission norms proposed by the Government, all trucks and buses in metros will have to be fitted with BS IV engines (currently it is BS III) by 2010. Once you move to BS IV, the engines will be fitted with common rail injectors, and to service these pumps you need advanced test benches like the EPS 815. It ensures increasing peak injection pressures, larger element diameters, new injection-pump types and injection systems (e.g., control-sleeve pump) resulting in heightened requirements and an increase in test-bench performance.


The EPS 815 is environmentally compatible and user-friendly due to reduction of oil vapour/oil mist. Outstanding rotational properties and speed stability ensure high repeat accuracy, especially during the injection process. Also ensured are high user comfort and high measuring accuracy. The weight compensation during vertical adjustment of the measuring device simplifies work considerably. It has longer service life because no rebending work has to be performed on the test lines (the measuring device can be adjusted in all three levels).

The EPS815 is fitted with integrated tachometer, stroke-counting mechanism and temperature controller which ensures ease of operation.
