  3. changes of pressure • 1912 • reliability and fuel efficiency • 12 • two-stroke • increases efficiency and overall power of the engine • connecting rod

  4. dieselengines are internalcombustionengines, p.2 • combustion • compression • ignition • relatively • comparison • economical • prevalent • mixture

  5. Diesel Enginetypes, p. 3 • Diesel engines can be divided into groups according to … • If we divide them into two/three groups according to …, we can say we have … • Next, we have the division by … • And finally, disel engines can be …
