Examination of LPG and Petrol Fuelled Ford Engines

摘要

This technical note covers the examination and comparison of the condition of Ford 4.1 liter XB engines operated for approximately 100 000 km on liquified petroleum gas (LPG) and petrol. The LPG engines exhibited less wear and were much cleaner than the petrol engines. However, the LPG exhaust valve faces were badly pitted and combustion chamber carbon build up was excessive. (Author)
