The task force on LPG vehicle stalling incidents, at its fourth meeting today (March 11), reviewed the work progress and analysed the findings of the investigation.

Since the spate of LPG vehicle incidents, the Electrical and Mechanical Services Department (EMSD) had taken 14 LPG samples from different locations including LPG terminals and filling stations, and the fuel tank of an LPG taxi which reportedly experienced severe engine stalling problems. The samples were sent to the Mainland and Germany in batches for laboratory tests. More than 150 tests were conducted on the samples sent to Germany.

All test results have been received and EMSD further confirmed and clarified the results with the laboratories and LPG suppliers. The test results showed that the quality of LPG would not affect the performance of vehicles.

The task force today also reviewed the progress of the LPG Vehicle Testing Scheme. To collect the performance data of different types of vehicles, 28 LPG taxis and two LPG minibuses have joined the scheme, and another four LPG minibuses are being arranged. So far, no vehicles under the scheme have experienced engine stalling problem relating to LPG quality.

Chairman of the task force and Deputy Director of Electrical and Mechanical Services, Mr Frank Chan, said, The task force collected extensive records and data, which cover the source of LPG supply, operation of LPG terminals and filling stations, as well as operation and maintenance of vehicles. The task force is thoroughly deliberating, consolidating and analysing all information collected including the laboratory test results from Germany and data from the vehicle testing scheme, so as to conduct a scientific and comprehensive investigation into the engine stalling incident based on facts and data. The task force understands the concerns of the public and relevant trades on the LPG vehicle stalling incidents. The task force will strive to publicise the investigation results on the cause of the incident as soon as possible.

Since the establishment of the EMSD hotline on January 4, a total of 150 cases relating to engine stalling had been received. The number of reports has dropped to single digit figures or zero since January 12.
