PFS Overview
- PFS Goal: Provide products
and services that enable the use of natural gas
- Wholly owned subsidiary of
Chesapeake Energy
– 2nd largest producer of natural gas in US behind XOM
- GE partner company
– CNG In A Box™ system

Conversion Overview
- EPA 2010 ISX15 (MY 2010 – 2012)
- Emissions equivalent or less than
diesel operation
- Capability of operating on 100%
diesel retained
- 65% maximum gas substitution;
majority of applicable torque/speed map in 55% - 65% range
- Similar aftertreatment duty cycle –
i.e. temps, frequency of regen and catalyst degradation
4
Conversion Overview
- Mechanically simple system
- Single point post turbo injection
- Cylinder pressures and engine
temperatures similar to diesel-only
- peration
- Comparable BSFC in dual-fuel
- peration
- Identical power map in dual-fuel mode

- 485 hp/1650 ft-lb
- Removable diesel tank weighed
before and after each run
- 4 runs – 2 diesel and 2 dual fuel
Diesel DNG Distance 109.6 mi 109.4 mi Time 1:44 1:43 Diesel Used 131 lbs 66 lbs Diesel Used 18.6 gal 9.4 gal
- Overall Diesel Displacement – 50%
- Assuming $3.95/gal diesel*, $1.69/gge CNG, and 5.9 mpg
result in a $20 fuel savings over 110 miles or 26% fuel cost reduction

Fuel Storage Options
- (3) 18.5" x 78" CNG Rack (behind cab)
– Approximately 1,300 lbs incremental weight – 45 dge; 500 miles before NG refuel required
- (1) 26” x 80” CNG Tank (frame rail mount)
– Approximately 350 lbs incremental weight – 38 dge; 420 miles before NG refuel required
- (1) 73 gal LNG tank (frame rail mount)
– Approximately 650 lbs incremental weight – 38 dge; 420 miles before NG refuel required
- (1) 120 gal LNG tank (frame rail mount)
– Approximately 985 lbs full – 63 dge; 675 miles before NG refuel required

Economics
- Turnkey conversion price of $25k - $35k
– $0.20 per mile fuel savings* – 12 - 18 month payback*
- Warranty
– Conversion warranty mirrors Cummins basic mechanical warranty (2yr/250k mile/6,250 hr) – OEM warranty remains intact after conversion – Must be able to link root cause of failure to conversion to void warranty – Dealer relationship important
