For instance, a 5cc dome on the top of a piston willincrease compression ratio versus a flat-top piston. Likewise, largevalve pockets will decrease compression. We'll get into the calculationslater.

Doubling a Gas Engine’s Compression Ratio Has Chaotic Results The crafty mechanics managed to get the engine to start and idle—but the party didn't last long. Ronan Glon Mar 26, 2025 10:05 AM EDT ...

The 2.0-litre VC-Turbo (short for variable compression-turbocharged), four-cylinder gas engine isn’t like a conventional combustion engine because the compression ratio can change on the fly.

Infiniti’s variable compression engine is a huge technological leap Clever new tech means changing compression ratios (and displacement) on the fly. Jonathan M. Gitlin – Aug 15, 2016 7:48 AM | 130 ...

Edited The MCE-5 engine from MCE-5 Development in Lyon, France (www.mce-5.com), varies its compression ratio and uses a combined gear and rod-crank mechanism.

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 high ...

The engine can vary the compression ratio from 8:1 under high power demand to 14:1 under low demand. The 2.0-liter engine produces 268 horsepower and 280 pound-feet of torque, good for the ...

The engine's actual capacity ranges from 1,970 to 1,997 cubic centimeters, depending on the compression ratio used. ALSO SEE: Food For Thought: Mercedes-Benz F700 Concept (Feb 2009) ...

Equally impressive is the Rogue’s estimated 33 mpg combined fuel economy with this engine. The VC Turbo achieves its compression ratios of 8.0 to 14.0:1 via a unique linkage in the crankcase.
