FPT unveils Cursor 13 natural gas engine

3 November 2017

FPT Industrial unveiled its newest natural gas engine, the Cursor 13 NG, intended for long-haulage commercial applications.

The Cursor 13 NG engine delivers maximum power of 460 hp at 1,900 rpm and 2,000 Nm torque at 1,100 rpm, thus offering 15% more power and 18% more torque than FPT’s 8.7 liter NG engine. Cursor 13 NG is a mono-fuel 100% natural gas engine; it can run with compressed natural gas (CNG), liquefied natural (LNG) gas starting from methane number 70 and biomethane.

The new natural gas engine, as all the other FPT NG engines, uses stoichiometric combustion. The C13 NG engine complies with Euro VI C emission standards using simple 3-way catalyst aftertretment. The engine does not use EGR.

The C13 engine features an inline 6-cylinder architecture with a compacted graphite iron (CGI) cylinder head, water cooled wastegate turbocharger and Ni-Resist cast-iron exhaust manifold. In addition, specific pistons rings and aluminium piston machining ensures an oil service interval of 90,000 km—the longest service interval on the 100% NG engines market, according to FPT. The engine uses FPT’s proprietary knock control technology, and a proprietary reactive air flow control management system—a new stoichiometric A/F ratio control logic that is applied during gearshifts.

Thanks to the absence of EGR as well as the multipoint fuel injection and fuel rails, the engine shows class-leading fuel consumption, with fuel cost savings up to 30-40% compared to the Cursor 460 hp diesel engine, said FPT.
