Thank you. The quality and condition of the fuel are critical on a diesel engine. The diesel engines that powers modern generators are built with an integral onboard fuel pump. Diesel fuel is the liquid fuel used in diesel engines (a compression engine as opposed to the automobile spark ignition engine), and the most common is a specific fraction distilled petroleum, generally boiling (within the boiling range of fuel oil) between 200–350 °C (392–662 °F) at atmospheric pressure. This pump moves more fuel than the generator will consume at any given load. • Pressure drop in nozzle ~30 bar << driving pressure (~1000 bar) • Injection velocity 500 m/s @ P of 1000 bar 2 P u fuel u L d Fuel Atomization Process • Liquid break up governed by balance between aerodynamic force and surface tension • Critical Webber number: Wb,critical ~ 30; diesel fuel surface tension ~ 2.5x10-2 N/m In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. Specific volumes above and below the critical pressure are obtained by linear interpolation 55 806 T.J. ~'VILLIA,MS for pressure form the critical pressure curve. Under sub-critical condition, the injected fuel undergoes primary and secondary breakup processes, followed by classical interphase vaporization. The difference between both values may be significant in some cases, which affects the control sizing calculations. Precise control of fuel injection is critical to the performance of a diesel engine. There are many different formulas thanks to which you can calculate the vapor pressure of water. Specific volumes above and below the critical pressure are obtained by linear interpolation 55 806 T.J. ~'VILLIA,MS for pressure form the critical pressure curve. At higher temperatures, the gas cannot be liquefied by pressure alone. True Or Pseudo Critical Pressure For Sizing Control Valves - posted in Chemical Process Simulation: What do you recommend for sizing control valves, true or pseudo critical pressure? The liquid is At the critical point there is no change of state when pressure is increased or if heat is added. This is where the turbocharger is critical to the power output and efficiency of the diesel engine.
Diesel engine fuel-injection systems are typically designed to provide injection pressures in the range of 7 to 70 megapascals (1,000 to 10,000 pounds per square inch). 8I~/8P is taken as a linear fmlction of tem- perature having one of two forms depending on whether the temperature is above or below 500 K. This article explains 7 of the most common causes for low oil pressure in a Caterpillar C7 but the principals can apply to the majority of diesel engines. 7 Reasons For Low Oil Pressure in a Diesel Engine. Gasoline or Petrol, Diesel, Fuel Oil etc. This pump will draw fuel from the day tank or fuel supply header and deliver it to the fuel injectors at the correct pressure.

Under super-critical condition with respect to both pressure and temperature, no distinct phase exists between liquid and gas. However, most issues can be resolved with simple solutions. The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. What do you think for hydrocarbons (diesel, fuel oil, HVGO...)?
