Westport LNG System for Heavy-Duty Trucks: 2006 Specifications

2006 Cummins ISX

Engine weight (dry): 3,021 lbs
Major engine features such as Cummins Intebrake™ and cruise control are retained.
Engine specifications to be confirmed by Westport before engine order.

2006 U.S. EPA & CARB Certification:

NOx+nmHC 1.2 g/bhp-hr CO 0.5 g/bhp-hr

PM 0.02 g/bhp-hr CO₂ 446 g/bhp-hr

Taking the place of a muffler is an integrated oxidation catalyst.

Two engine ratings are offered.

Engine Model	Advertised Horsepower (hp)	Peak Torque (lb-ft)
450	450	1,650 @ 1,200 RPM
400	400	1,450 @ 1,200 RPM

Currently available in models from:

Kenworth

Compatible models from:

Volvo Peterbilt International

transmission compatibility
Available with manual transmissions compatible with the Cummins ISX and appropriate for the engine rating.

OEM to provide options based on vehicle application.

Tanks are installed along the frame rail, like diesel tanks, and can be used in any combination (maximum of two tanks). To estimate vehicle range, multiply the standard diesel vehicle fuel economy for the applications by the usable diesel equivalent gallons (DEG) value provided in the table below.

Gross Tank Size (US Gal)	Tank 1 Volume (US Gal)	Tank 2 Volume (US Gal)	Nominal Volume (US Gal)	Diesel Equivalent Gallons¹ (DEG)	Approx. Incremental Vehicle Weight² (lbs)	Approx. Chassis Wheelbase³ (inches)
70	70	—	63	33	790	165
100	100	—	90	46	905	170
120	120	—	108	56	970	180
140	70	70	126	66	1,350	190
170	70	100	153	79	1,465	195
190	70	120	171	89	1,530	210
200	100	100	180	92	1,580	210
220	100	120	198	102	1,645	210
240	120	120	216	112	1,710	215

Calculated on an energy equivalent basis.
Estimated incremental vehicle weight is based on the weight of the Westport LNG system,
less the weight of removed diesel components.
Actual wheelbase requirements dependant on vehicle specification.
