Mount Erciyes is renowned in Turkey for high altitude winter sports, towering over the city of Kayseri located on the plains below. Connecting the ski resort with the city center and the villages along the way is bus route 4, running a fleet of Temsa-compressed natural gas (CNG) buses powered by Cummins 8.9-litre engines.

The Diesel Particulate Filter (DPF) is a critical component of your buses’ diesel engines. By capturing and keeping diesel particulate matter, nitrogen oxide and hydrocarbons from entering the air we breathe, DPFs play a critical role in meeting EPA standards for diesel engine exhaust quality.

One of the most crucial aspects to engine performance is fuel cleanliness. With the use of high-pressure common rail with higher injection pressure and atomized fuel (compared to pre-2010 engines), any fuel-contaminated debris can cause downstream issues. Therefore, it is critical that the fuel going to the injectors be as clean as possible and any debris is trapped securely for removal.

Oil is a critical component to the diesel engine life and performance. Besides lubricating internal components, oil helps remove excess heat and cleans and seals internal components. It is in contact with more critical components of the engine than any other fluid.
