FPT International introduces 8.7-liter CNG engine in China
26 May 2016
FPT Industrial has extended its range of on-road alternative fuel solutions with the 8.7-liter Cursor 9 CNG, based on the Cursor 9 diesel architecture. The Cursor 9 CNG offers power up to 400 hp @ 2000 rpm, and torque up to 1700 N·m @ 1.200 rpm, while at the same time having emissions lower than Euro VI. The CNG engine delivers equivalent performance to its diesel counterpart.
The 6-cylinder engine is suited for applications such as heavy haulage, garbage collection, city and intercity transportation, and can be fueled by compressed (CNG), liquefied (LNG) or renewable (bio-methane) natural gas.
The Cursor 9 CNG uses stoichiometric combustion to generate its power. To comply with Euro VI the Cursor 9 CNG does not need Exhaust Gas Recirculation (EGR) or Selective Catalytic Reduction (SCR), but relies on a simple three-way catalyst.
The Cursor 9 CNG, which replaces the 7.8-liter Cursor 8 CNG, features the larger displacement, new multipoint fuel injectors and a new fuel rail to allow for a higher flow rate. This, together with the modified cylinder head, characterized by intake ports with an optimized swirl angle, grants class leading fuel consumption.
Compared to the Cursor 9 diesel, the new engine has a Ni-Resist cast-iron exhaust manifold and water cooled wastegate turbocharger, increasing reliability. This is further supported by new piston rings to increase the oil service intervals by 17% vs. the Cursor 8 CNG, arriving at best in class for scheduled maintenance.
