The Nissan HR12DDR is a 1.2 l (1,198 cc, 73.11
cubic inches) straight three, four-stroke supercharged internal
combustion gasoline engine from Nissan HR family, manufactured by Aichi
Machine Industry.
The HR12DDR is a direct-injected (Direct Injection Gasoline system or
DIG), supercharged engine. The engine used the Miller cycle in witch
intake valve is open even during the compression stroke. This engine is
also equipped with Continuous Variable Valve Timing Control System
(CVTCS), variable capacity oil pump and electronic, distributor less
type ignition system with individual ignition coil for each cylinder. It
has a cast aluminum engine block with four main bearings and aluminum
DOHC (dual overhead camshaft) cylinder head with 4 valves per cylinder.
The cylinder bore is 78.0 mm (3.07 in) and the piston stroke is 83.6 mm
(3.29 in), compression ratio rating is 12:1 or 13:1. The Nissan HR12DDR
produced 98 PS (72 kW; 97 HP) at 5,600 rpm of max power and 143 Nm (14.6
kgm; 105.5 lb-ft) at 4,400 rpm of peak torque.
