Isuzu Motors Limited has recently-developed 2.5 liter and 2.8 liter diesel engines to power Isuzu ELF trucks (payload 1-2 tons). These two engines are high fuel economy direct injection diesels featuring a square cavity combustion chamber and Bosch VE distributor type injection pump. To reduce the D.I. diesel engine noises, the combustion chamber, fuel injection system, and cylinder block construction have been improved. In addition, a vibration damping sheet oil pan, timing belt drive, and cylinder block cover are employed. The two diesel engines are small size, light weight, highly reliable engines to be successors to the 2.0, 2.2 and 2.4 liter Isuzu C-series diesel engines. To date, 2 million of these engines have been produced to power the Isuzu ELF trucks and other vehicles as well as a wide variety of industrial and marine applications. The basic engine specifications are: 4 cylinder, OHV, bore 93mm, stroke 92mm (2499CC), 102mm (2771CC), maximum power output (DIN) 50KW/3,600rpm (2.5L) and 57KW/3,600rpm (2.8L).
