A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Any diesel-engine manufacturer that confidently claims it produces an oil-burner with the “world’s lowest compression ratio,” will no doubt draw the immediate attention of inquisitive enthusiasts, ...

The innovative engine appears to be a victim of its own complexity. It couldn't come at a worse time for Nissan. Nissan's variable-compression engine once held so much promise. The so-called VC-Turbo ...

When Chrysler introduced the 5.9-liter Magnum engine in 1993, it was a big step forward in terms of production engine output. The 360ci powerplant was originally introduced in 1971 as a ...

Nissan wowed the automotive world when it introduced its Variable Compression (VC) Turbo technology in 2016. The innovative engine advancement, which essentially was capable of on-the-fly compression ...

Infiniti's newest engine is an engineering marvel. The VC-T engine (for "variable compression, turbocharged") can adjust its compression ratio between 8:1 and 14:1 on the fly, offering ...

A compression test reveals the condition of your engine's valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi per ...

This is a preview. Log in through your library . Abstract Using hydrogen as a fuel, this chemical-kinetics study qualitatively examines the phenomenon of "frozen equilibrium" in Stratified Charge ...

Despite the turbulence Nissan has faced over the past few years, some of its technology is undeniably impressive. Perhaps the crowning jewel of this engineering power is its variable compression ...
