Nissan to expand its production line from VCR Engine to HV
Nissan announced its expansion of the production line for the Variable Compression Ratio (VCR) Engine due to the world’s first success of Nissan’s actual implementation with 2,000cc engine with the expectation to implement as the power generator for the hybrid system of which the technology was under development in order to increase the thermal efficiency of the engine from 40% to 50% in 2050, offering fuel efficiency to travel further. The VCR Engine helped reduce pollution caused by the internal combustion engine.
Engine ring and actuator were placed on top-under of the piston in the VCR Engine’s piston layout structure of Nissan which helped the engine to work smoothly with the compression ratio from 8–14 while running. This led to the reduction of the compression upon heavy loads, the prevention of the abnormal combustion, and the increase of the compression upon light loads for the reduction of fuel consumption and the enhancement of the running efficiency.
The 4-cylinder turbo 2,000cc engine would be used in “QX50” SUV, the new model from “INFINITI”, the luxury brand which had the maximum wattage power of 220 KW and the torque of 380 Nm, equivalent to 6-cylinder 3,500cc engine.
At present, the VCR technology is under development in order to be used by other engines such as the 3-cylinder engine.
In addition, Nissan had also forecast the implementation of the power generator of the “E-POWER” engine
