DOE Warns Against Use of Dual Fuel System in Vehicles
June 27, 2008 by Tsikot
Energy Secretary Angelo T. Reyes has warned the transport sector on the ill-effects of the use of liquefied petroleum gas (LPG) on an engine system that has not been yet properly tested.
Specifically, Reyes was referring to a dual fuel system which utilizes in-line blending of diesel (70 percent) and LPG (30 percent).
“The results of the tests made by the DOST (Department of Science and Technology) on this system have been proven to be very inconclusive,” Reyes said.
He pointed out that “LPG and diesel combination are not proven to be safe.”
Reyes said the DOE and its partners will provide the guidelines and accreditation requirements for the retrofitting of public jeepneys and buses from diesel (compression ignition) to spark-ignition engines to allow the 100-percent utilization of alternative fuels such as LPG, compressed natural gas (CNG) and 85 percent bioethanol blends.
President Arroyo on June 16 ordered the fuel conversion of jeepneys and buses to LPG and CNG.
Reyes has recommended to Executive Secretary Eduardo Ermita that the DOE conduct an appropriate test prior to the full enforcement of the mixed-fuel technology.
Meanwhile, the DOE shall initiate the retrofitting of public jeepneys and buses from diesel to spark-ignition engines to enable the full utilization of LPG, CNG and 85 percent bioethanol blends.
The move to utilize alternative fuels is one of the government’s ways to combat the continually rising prices of fossil fuels.
At the same time, it will boost public safety, health, the environment and compliance with standards as primary concerns.
