The KH5T is a 1.5 L (1461 cc) DIG-T (Direct Injection Gasoline-Turbocharged) inline-3 12-valve engine, with a bore x stroke of 79.7 mm × 81.1 mm (3.14 in × 3.19 in).[clarification needed]. Power output is 157 bhp (159 PS; 117 kW) and 240 N⋅m (177 lb⋅ft) of torque.The variation in compression ratio ranges between 8:1 and 14:1. This is achieved by the movement of an actuator which changes the length of the piston stroke according to the demand for power.
Applications:
The KR15DDT 3 cylinder engine is firstly introduced in the fourth-generation X-Trail.[1]
Applications:
The KR20DDET was announced at the 2016 Paris Motor Show as the VC Turbo which had Nissan's new variable compression technology. The engine was introduced to Nissan's production cars in 2019 in the Infiniti QX50 and the Nissan Altima replacing the previous V6 options.[2] It was touted as the world’s first production-ready variable compression ratio engine.[3]
