Nissan has always been a forerunner in the field of powertrain development. This VC Turbo engine is yet another example.
Nissan has developed a VC Turbo (Variable Compression) engine that can demonstrate the characteristics of both petrol and diesel engines. Nissan is constantly developing innovative engine technology. This time, they’ve created an engine with a Variable Compression Ratio, which essentially allows a single Wengine to exhibit the characteristics of both petrol and diesel, depending on the situation and demand. Let us now look at how Nissan was able to accomplish this.
This engine has a configuration that allows the powertrain to operate with variable compression ratios. A multi-link system is connected to the crankshaft. The length of the connecting rod can be changed by switching a lever. This also changes the size of the combustion chamber. As a result, the engine runs in a regular cycle, also known as the Atkinson cycle. The compression ratio varies between 8:1 and 14:1. At low speeds, the Atkinson cycle kicks in, and the turbocharger engages. Lowering the compression ratio eliminates the problem of knocking and allows the piston to move quickly without the risk of misfire or detonation, which is common in petrol engines with high compression ratios.
When the driver desires more power and fully depresses the accelerator pedal, a higher compression ratio is selected, resulting in high thermal and fuel efficiency. This is what happens in diesel engines with high compression ratios. That is why they have a longer range. However, Nissan’s VC turbo engine combines the best features of both engines. As a result, when needed, one gets better fuel economy and high performance. Regardless of these variables, emissions are always under control.
