Clean Air Power withdraws Genesis-EDGE engine from testing

Clean Air Power sent its shares firmly into the red on Thursday after announced that its US Genesis-EDGE Dual-Fuel test engine has been temporarily withdrawn from testing thanks to a technical issue.The group, which develops compression-ignited natural gas engine management systems for heavy-duty engines, said that while in pre-certification testing, a technical issue was found with the selective catalytic reduction (SCR) after-treatment system on the base diesel engine, preventing the completion of a full test cycle.It added that once the issue is resolved the engine will be returned to complete certification "at the earliest opportunity". "Whilst technical issues have led to a short temporary delay in the progress of our US Genesis-EDGE product, the success of the engine in meeting emissions targets in pre-certification testing means that I am confident of achieving EPA approval once testing is resumed," chief executive John Pettitt said."We are now focused on resolving the technical issues, in the next few weeks, so that we can continue the testing programme and achieve certification and our first US sales as quickly as possible."The news had pushed shares 13% lower to 2.17p by 10:00.
