The Navistar DT (Diesel Turbocharged or Diesel Turbo) engine family is a line of mid-range inline-6 diesel engines.With horsepower ratings ranging from 170 hp (130 kW) to 350 hp (260 kW), the Navistar DT engines are used primarily in medium-duty truck and bus applications such as school buses, although some versions have been developed for heavy-duty regional-haul and severe-service applications.
With an optimal diesel particulate filter (DPF), soot emissions may be decreased to 0.001 g/km or less. [10] The quality of the fuel also influences the formation of these particles. For example, a high sulphur content diesel produces more particles. Lower sulphur fuel produces fewer particles, and allows use of particulate filters.
It is a family of 3-cylinder and 4-cylinder diesel engines featuring modular diesel engine system (MDB (Modularer Diesel Motor Baukasten)), [5] [6] [7] with dual-loop EGR system, with high pressure EGR and a cooled low-pressure EGR loops; variable valve train (VVT) with a camshaft adjuster, Bosch CRS 2-20 2000 bar common rail injection system ...
[1] Water can get into diesel fuel as a result of condensation, rainwater penetration or adsorption from the air — modern biodiesel is especially hygroscopic . The presence of water then encourages microbial growth which either occurs at the interface between the oil and water or on the tank walls, depending on whether the microbes need oxygen .
The Navistar VT engine family is a line of diesel engines that was produced by International Truck and Engine (Navistar International) from 2003 to 2016.Developed as the replacement for the T444E V8, the VT V6 and V8 diesels were the smallest diesel engines used in Navistar vehicles, slotted below the DT inline-6 engine family.
International Motors, LLC (formerly Navistar International Corporation) is an American holding company created in 1986. The successor to the International Harvester manufacturing company, International produces trucks and diesel engines under its own brand; [3] the company produces buses under the IC Bus name.
Typically, the frozen DEF is melted by heat from the engine, e.g. engine coolant passing through the DEF tank, governed by a thermostatic coolant control valve. This method may take significant time before the SCR exhaust cleaning system is fully operational, often up to an hour. [4]
