DDT series
HR10DDT
The HR10DDT is a 1.0 L dual direct injected, supercharged, turbocharged, straight-3 engine that was anticipated for use in the 2010 Nissan Micra,[1] but was ultimately dropped in favour of the HR10/12DE and still-simpler HD12DDR/DDT variants, dependent on vehicle and application.
HR is a family of straight-3 and straight-4 automobile engines co-developed by Nissan (Aichi Kikai) and Renault. Renault calls it the H engine. There are two basic designs with 72.2 mm bore resp. 78 mm bore diametre. The smaller engines are available as 3-cylinders with a displacement of 0.9 l or 1.0 l, 4-cylinders at 1.2 l or 1.33 l (4-cylinders also with direct injection). There are rumors about a 0.8 litre 3-cylinder in India. In the list below the HRA2DDT is the only engine from this small design.
The below mentioned HR10DDT, HR10DE, HR12DE and HR12DDR are part of the bigger design.
