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.

I was deeply impressed by the VC-Turbo engine when purchasing a car. This model, Nissan's variable compression ratio turbocharged engine like the KR20 used in the Altima, intelligently adapts to road conditions through compression ratio adjustment. It delivers noticeable fuel efficiency in city driving without compromising acceleration. As an average driver, the most practical benefit is the 20% reduction in fuel consumption, saving money on long trips and requiring fewer gas station visits. The engine runs smoothly with minimal noise – a stark contrast to the noticeable vibrations in my friend's older car. After Nissan incorporated this technology into the QX50, it proved highly reliable with straightforward maintenance, offering long-term cost and hassle savings. Choosing such an innovative model when buying a car is always a wise decision.

New drivers learn that VC-Turbo is Nissan's variable compression ratio engine model. The compression ratio refers to the proportion of the air-fuel mixture compressed by the engine, which can automatically change to save fuel while delivering strong performance. Used in the Altima, simply put, while driving, the engine acts like a smart robot adjusting itself to eliminate hassle, with low noise and straightforward maintenance. Nissan's design makes it easy for beginners to get the hang of it.

Can Revving the Engine in Neutral Charge the Car Battery?

Revving the engine in neutral can charge the car battery. As long as the engine is running, the battery is being charged. It is better to turn off electrical equipment such as the radio and headlights. If the battery is not old, it can be removed for charging. If it has been used for more than two years, it is recommended to replace the battery. The engine, alternator, battery, and electrical loads in a car form an interconnected system. When restarting the engine after it has been turned off, the charging state of the battery must be considered. The battery can be seen as an energy storage device that powers various loads, while the alternator must charge the battery, acting as the energy provider. If the battery's discharge exceeds its charge, the battery will also discharge.
