      Other types of engine designs; Atkinson Cycle Engine. Uses the idea that the intake valve is left open longer - past BDC compression. When used with a variable valve timing system, it allows control over engine displacement! Highway = 2.0 L. WOT or high load = 2.5 L. Advantage, efficient. Disadvantage requires variable valve timing and extra ...

      What he did was to run one engine at idle, and the other at high power, thus reducing overall TSFC (fuel flow). In other words, to get total thrust T, instead of operating each engine at thrust T/2, he operated one engine at very low thrust and the other at high thrust. Figure 6.4. Specific Fuel Consumption vs. Engine RPM for Typical Turbine Engine

      When the engine is charging the storage batteries, it is beneficial to adjust the engine speed and load to maximize the fuel efficiency and therefore increase the overall miles/gallon capability of the car. The fuel efficiency can be maximized when the engine output (brake horsepower or watts) is high and fuel consumption rate (kg/sec) is low.

      This is the amount of spark advance where the engine just begins to knock. On a normally aspirated, low compression engine, BDL occurs at advance values higher than MBT. On high compression or supercharged engines, BDL can occur at advance values lower than MBT. Raising the octane value of the fuel moves the BDL point higher up.

      I disagree. 15% leakdown is a worn out engine. 3% is good, 5% is fair but I would not accept 5% it for a new rebuild. I shoot for 2-3%. Guess it depends on what they call "rebuilt". My concern would be the difference in compression between #2 and #3. 15-PSI variance high to low is too much for a new engine. That is 10% of the higher compression ...

      In this part we assume that the torsion produce by the rotation of crankshaft will affected directly the rod, and the force of compression is the same of force P acting on head of piston rod by static, the torsion acting on rod produce by crankshaft will be: T = Rcranckshaft * F (compression of crankshaft) = (1.5/2+.5)*0.0254* (532.4KN) = 16.9 KN-m

      High and low pressure systems are used to drive aircraft and engine components or accessories, while the interstage bleed valves are required to ensure compressor stability. Low pressure bleed air is taken from the back end of the low pressure compressor. High pressure bleed air is taken from the back end of the high pressure compressor
