Transcript

  • 1. New Technologies In EnginesSubmitted BySandeep singhGaganpreet singhHarish yadavParvinder singh
  • 2. Advantages Of New Technology In Engines Economical Less Pollution More Efficiency
  • 3. IntroductionNew technology in various engine systems such as. Alternative Fuel Ignition system Designs of crankshafts Valves Pistons Aluminium Body TwinPower Turbo engines
  • 4. Alternative FuelsEngine in which the combustion of a fuel (normally a fossil fuel) occurswith an oxidizer (usually air) in a combustion chamber that is an integralpart of the working fluid flow circuit. Alternative fuels, known as non-conventional or advanced fuels, are any materials or substances that canbe used as fuels, other than conventional fuels. Algae based fuels Alcohol fuels Biofuels and vegoils Air Hydrogen Batteries
  • 5. Variable Valve Timing with intelligenceThe shaft spins just like a regularcamshaft -- but by gradually sliding thecamshaft laterally as the engine speedand load increase, the valve timing canbe optimized. There are many ways inwhich this can be achieved, ranging frommechanical devices to electro-hydraulicand camless system
  • 6. VALVE TRONIC ENGINESThe Valvetronic engine is the worlds first enginewithout a throttle butterfly. Valvetronic varieswith the timing and the lift of the intake valves.This valvetronic engines allows the engine tobreathe more freely, fuel consumption isreduced by 10%. Valvetronic reducesmaintenance costs, improves cold startbehavior, lowers exhaust emissions, andprovides a smoother running engine.
  • 7. Aluminium engine bodyAn aluminium engine body comprises a main bodyand the outer cover body A modern car engine withcomponents made of aluminium can be 24 percentlighter than one with components madeof steel, which also allows fuel consumptionto be reduced by 2 liters per 100 kilometers.
  • 8. NEW TEFLON PADS PISTONSThe Cummins V28 engines have used a new technology fortheir pistons- they have two Teflon pads and the pistons alsoincorporate a cutback headland.Teflon padded pistons will eliminate cylinder liner waterjacket cavitation corrosion and increase cylinder liner life andhence engine life. Improved oil consumption Increased piston and cylinder liner life Teflon pad
  • 9. Cavity In Pistonengine has the combustion chamber cavity in thecrown of the piston. This design is called aMexican Hat piston. This Piston have a widepressure range, can reach high pressures and thepressure can be controlled without an impact onthe rate of flow it assists in creating airturbulence, which mixes the fuel with air duringthe last part of compression in diesel engines.
  • 10. VARIABLE COMPRESSION RATIOEccentric crankshaft engine: The motor provides adjustment in 0.1s for decreasing compression ratio and 0.5s for increasing ratio.The Saab Variable Compression : optimum compression ratio of 14:1 The compression ratio can be lowered to 8:1 at high load.
  • 11. FAST SOLENOID COMMON RAILwhich enable multiple injectionevents, increased injection pressurecapability and a new closed loop controlsystem known as Accelerometer PilotControl (APC). and the system is correctlycalibrated. Solenoid valves make possiblefine electronic control over the fuelinjection time and quantity.
  • 12. TwinPower Turbo enginesTwinPower Turbo engines are made inlightweight aluminium construction and usevariable turbine geometry TwinPower Turbopetrol engines is applied throughout the series.Innovative turbocharger technology and Double-Vanos increase performance and ensurespontaneous response even at low speeds.
