A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

Mazda's hotly anticipated SKYACTIV-X Spark Controlled Compression Ignition engine has been described as the "Holy Grail" of gasoline motors—something with diesel-like fuel economy, but far lower ...

The automotive industry continues to be a hotbed of innovation, with activity driven by factors such as auto-ignition properties of the fuel, fuel concentration, and residual rate, and growing ...

SAE Transactions, Vol. 96, Section 4: RECIPROCATING ENGINES–SPARK IGNITION AND DIESEL (1987), pp. 614-623 (10 pages) A single-cylinder, variable–compression ratio, direct–injection diesel engine was ...

Fuel effects on combustion characteristics, including combustion robustness/stability, for partially premixed compression ignition (PPCI) combustion was investigated using Delphi’s second-generation ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...
