This document discusses the benefits of converting diesel vehicles to operate as dual-fuel vehicles using both diesel fuel and compressed natural gas (CNG). It notes that dual-fuel conversion is more affordable and easier to implement than a full CNG conversion. Dual-fuel vehicles can save up to 34% on fuel costs compared to diesel alone. They also have lower maintenance needs than fully converted CNG vehicles since they can still operate on diesel if any CNG-related issues occur. The document promotes dual-fuel conversion as a way for transportation companies to cut fuel costs and gain a competitive advantage during difficult market conditions while avoiding the high costs of fully replacing their fleets.

• Tahografs and Moscow entrance restriction have took their toll: while before
10-11 trips Moscow-S-Petersburg per month were a standard, but now 7
trips is a kind of achievement even.
• Container delivery tariffs dropped at 10% in rubles, moreover in USD at 60%,
while one container delivery expenses increased at 20% in rubles.
• Goods turnover , by eye, decreased 2 times - basing on queues absence in
Petersburg see-port and trucks met at highway.
• Drivers income decreased from 50 000 rubles to 35 000 rubles
• Coming changes (entities overweight responsibility increasing, highway
payment for heavy-duty trucks implementation) surely will bankrupt
majority of transportation companies
• But exit the business is not a solution, because of abovementioned reasons
to sell a truck without losses is virtually impossible.

Resolution

Regarding changing of Technical Regalement “Requirements to emission of
the vehicles allowed to usage in Russian Federation ”
“Dual-fuel engines" is an engine same
time using diesel fuel and gaseous
fuel, while their ratio can vary
depending on engine regimes;

Operational saving. 1 liter of diesel fuel is substituted by 1,3nm3 of CNG for 100%
CNG engines and by 1,1nm3 of CNG for dual-fuel engines. Thus saving (taking DF
33 rub/L and CNG 13rub/nm3) is 48% и 34% respectively
Capital costs : Dual-fuel conversion is 3 times cheaper comparing with 100% CNG
conversion
CNG cylinders weight and volume. 3 times less for duel-fuel engines. For
example, for tractor truck you normally need 3 cylinders 145L each, total weight
450kg for dual-fuel and 9 cylinders 1,5 tons for 100% CNG
Conversion time. 14 days for 100% CNG and 3 days for dual-fuel. For dual-fuel
engines conversion can be made at client headquarters, no need to move vehicle
to conversion center.
Easy exit: Dual-fuel vehicle can be easily sold as diesel one, while 100% CNG
vehicle sale is doubtful

10. CNGas.RU 10
Dual-fuel vehicle is always in the ranks. Any problem with
CNG, disregarding in dual-fuel equipment or at CNG fueling
station can occur, but dual-fuel vehicle can work in diesel-
only regime.
Maintenance without change.
Service and washing any places. After CNG relieving and
bleeding down vehicle can be repaired at standard
workshops, no need special-equipped chambers needed
for CNG vehicles..

• Under present conditions transportation companies
have nothing to do but forget about fleet renewal, and
old engines do not become more efficient.
• Competition increases. Only the best in the industry will
survive.
• Dual-fuel techologies provide substancial competition
advantage at transportation market by the way of higher
fuel efficency at existing fleet.
