When Perodua launch its new model Axia recently, one of the most interesting fact is the new engine they are using under code of 1KR-DE2.
Most of us noted that Perodua Axia is base of underpinnings Daihatsu Ayla and Toyota Agya model, but it seem the previous engine code is stated 1KR-FE, after that 1KR-DE is launched and the latest is 1KR-DE2, here some fact from Wikipedia website,
1KR-FE used in Daihatsu Sirion, Toyota Aygo, Citroën C1 and Peugeot 107
The
1KR-FE is a 1.0 L (996 cc) version built in
Japan and
Poland. Bore is 71 mm and stroke is 84 mm, with a
compression ratio of 10.5:1. Output is 67 PS (49 kW) at 6000 rpm with 91 N·m (67 lb·ft) of torque at 4800 rpm or 71 PS (52 kW) at 6000 rpm with 94 N·m (69 lb·ft) of torque at 3600 rpm. When originally on sale it met
European emission standard EU4 requirements and had
CO
2 levels of 109 g/km, but current applications meet
European emission standard EU5 and can have
CO
2 levels as low as 99 g/km.
[1] This engine has been given the 2007, 2008, 2009 and 2010
[2]International Engine of the Year awards in the sub-1.0 liter category.
Applications:
The
1KR-DE is the non
VVT-i variant of the 1KR engine. It produces less power and
torque than 1KR-FE. Output is 65 PS (48 kW) at 6000rpm and 85 N·m (63 lb·ft) of
torque at 3600rpm. Bore is 71 mm and stroke is 84 mm, while the
engine displacement is 1.0 L (998 cc).

1KR-DE2[edit]
The
1KR-DE2 is the more powerful variant of the 1KR-DE engine which is redesigned by Perodua. It produces 66 PS (49 kW) at 6000rpm and 90 N·m (66 lb·ft) of
torque at 3600rpm. Like the 1KR-DE, bore and stroke are at 71mm and 84mm respectively, and
engine displacement remains at (998 cc)
[6][7] The 1KR-DE2 achieves
Euro IV emission standard, but still lacks
VVT-i when compared to 1KR-FE. The compression ratio for this engine is 11:1.
