What is the model of Nissan's variable compression ratio engine?
2 Answers
Nissan's variable compression ratio engine model is VC-Turbo, which is a 2.0L 4-cylinder naturally aspirated engine. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by burning the expanded gas in a sealed cylinder to push the piston to do work. Nissan models include: Bluebird, Sylphy, Teana, Murano, X-Trail, Qashqai, etc. Taking the 2021 Sylphy as an example, it is a compact car with body dimensions of: length 4631mm, width 1760mm, height 1503mm, wheelbase 2700mm, fuel tank capacity 50L, and trunk capacity 510L.
I'm particularly fascinated by automotive engine technology. Nissan's variable compression ratio engine is called VC-Turbo, with specific models including the KR15DDT and KR20DDT series. It was first introduced in 2018 and used in models like the Infiniti QX50 and Nissan Altima. Variable compression ratio means the compression can automatically adjust from 8:1 to 14:1 under different driving conditions, achieved through a unique mechanical linkage system to optimize combustion. The driving experience is exceptional - it delivers race-car-like power at high speeds while being fuel-efficient and quiet in traffic. Nissan spent nearly 20 years developing this innovative technology to address fuel waste in traditional engines. Personally, I believe this represents the next step in engine development as it balances performance and environmental friendliness, with potential future applications in more vehicle types like SUVs or hybrids.
