WebJun 22, 2016 · An Atkinson-cycle engine works the same way, but with a twist. In a regular engine, the intake valve stays closed when the piston moves up on its compression stroke, creating pressure in the cylinder. WebAug 11, 2015 · Very basic - it has a shorter compression cycle than the power cycle - which improves efficiency. The original Atkinson engine achieved this through bell cranks and levers. In the modern engine this is achieved by varying the intake valve event. Intake valve stays open as the piston is coming up, pushing some of the charge back up the intake port. hawthorne united states of america

Process 1-2: Reversible adiabatic compression Where r = compression ratio Process 2 -3: Heat additions at constant Volume Q in = m C v [T 3 -T 2] Process 3-4: Reversible adiabatic expansion WebThe operation of the Atkinson cycle is depicted on a p - V diagram in Fig. 5.4. The cycle comprises the following processes: adiabatic compression 1 → 2, isochoric heat addition 2 → 3, adiabatic expansion 3 → 4, and isobaric heat removal. For this cycle, we have V2 = V3, p4 = p1, CR = V4 / V3, PR = p3 / p4, and TR = T3 / T1. Fig. 5.4. hawthorne united states
