The efficient and robust Caterpillar C18 diesel engine with exhaust aftertreatment system complies with the exhaust gas limits stipulated for 97/68/EC-EU Stage IV as well as being equipped for 2016/1628-EU Stage V. This means that it is also compatible with upcoming emission regulations in the rail industry.
The exhaust aftertreatment system consists of a wall-flow or “closed” exhaust particulate filter with an upstream diesel oxidation catalyst (DOC) and downstream selective catalytic reduction (SCR) that reduces nitrogen oxides (NOx) in order to meet the required thresholds. The exhaust particulate filter is cleaned every 5,000 operating hours and regenerated on the go using an active burner system.
The particulate filter boasts a filtration efficiency of over 97%, bringing the exhaust aftertreatment system in line with the requirements of the Swiss Federal Office for the Environment (FOEN) as well. The filter system also enables the engine to be used on German building sites in low-emission zones such as city centers – anywhere, in fact, with strict environmental regulations.
With an output range of between 429 and 470 kW, the six-cylinder in-line engine is also compact enough to be installed in narrow spaces and can be fitted with optional extra components such as a cooling system.
Project support from development through to commissioning
Zeppelin Power Systems provides a full range of services, from customized development, engineering, and manufacturing the drive units in the desired configuration right through to commissioning and final installation inspections.
“Our engineers implement our drive concepts in close cooperation with the customer,” says Thorsten Meyer, Sales Manager Rail Vehicles at Zeppelin Power Systems. “Of course, we also provide customized solutions, such as installing the engine in a narrow space, and take account of special equipment like standard or rotary snowplows.”
At the iaf, the service team from Zeppelin Power Systems will be showcasing its comprehensive range of services for rail vehicles both at its stand in the South Hall and outdoors in exhibition area A-220.
The team will give information about customized inspection and servicing plans with detailed servicing documentation and a thorough status analysis for prevention and early detection to ensure that rail vehicles run reliably. This includes extensive availability of spare parts and global service coverage via its network of Caterpillar dealers.
