BDC = Bottom Dead Center TDC = Top Dead Center * Increase the diameter or the stroke length will increase the cylinder volume, the ratio . Calculate Engine Performance Coefficient. Determining the parts that best suit your engine require some complex equations. A vehicle's gains depend on a variety of factors, including (but not limited to) the age and condition of the vehicle, its components and service history, ambient temperature . Importantly, engines (except steam) require an oxidizer now in a 1-to-1 ratio with the fuel in order to burn. This calculator gives the baseline horsepower and cubic feet per minute (cfm) that an engine will develop at its maximum rpm given the volumetric efficiency of the engine. Size required to match a 7200 RPM SATA drive (GB) Standard persistent disk. This is the same expression as we arrived at before for the jet engine (as you might have expected). p e = exhaust pressure at nozzle exit. V c = cylinder swept volume [cm 3 (cc) or L]. d c = cylinder diameter [cm or cm/10]. This seems very confusing but it is because even though it is a -cc on the piston, those same cc's are gained in cylinder volume. in Inches : 1/4 Mile ET: 1/4 Mile Top End Speed: Ideal 1/4 Mile Gear Ratio: This utility performs an approximate calculation of launch vehicle payload performance from any launch site to any orbit.
