Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...

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 ...

The compression ratio clarification wasn’t the only one issued by the FIA. For some time now, F1 has used ultrasonic fuel ...

A running engine produces heat, which expands its metal body, thereby increasing its compression ratio. This is true for ...

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 ...

SAE Transactions, Vol. 110, Section 3: JOURNAL OF ENGINES (2001), pp. 1234-1252 (19 pages) Using methanol as a fuel, this study examines the chemical-kinetics mechanism responsible for the enhancement ...

With Infiniti having recently revolutionized internal combustion engines by the introduction of a variable compression ratio mill, we're here to take the time to zoom in on the tech introduced by the ...
