TL;DR: In this article, the effects of unleaded gasoline (E0) and ethanol-ethanol blends (E50 and E85) on engine performance and pollutant emissions were investigated experimentally in a single cylinder four-stroke spark-ignition engine at two compression ratios (10:1 and 11:1).

TL;DR: In this article, the effect of compression ratio on engine performance and exhaust emissions was examined at stoichiometric air/fuel ratio, full load and minimum advanced timing for the best torque MBT in a single cylinder, four stroke, with variable compression ratio and spark ignition engine.

TL;DR: In this paper, the effects of using unleaded gasoline and ethanol blends on engine performance and exhaust emissions have been experimentally investigated on a Hydra single-cylinder, four-stroke, spark ignition engine.

TL;DR: In this paper, a back-propagation learning algorithm with two different variants and logistic sigmoid transfer function were used in the network to determine the engine torque and specific fuel consumption based on the ignition timing, relative air-fuel ratio (RAFR), and compression ratio at a constant speed of 2000 rpm and at wide open throttle (WOT).

TL;DR: In this paper, a beta-type Stirling engine, with a 192 cc total swept-volume, was manufactured and its performance tested at atmospheric pressure, and the hot-source temperature was chosen as a fundamental parameter of the experimental study.
