1. Atkinson cycle
Atkinson cycle engine in comparison with the conventional work cycle, which is the power stroke than the maximum characteristic length of the compression stroke, that is, we often say that the expansion ratio greater than compression . Longer working stroke can be more effectively utilize high pressure exhaust gas remaining after combustion, the fuel efficiency is higher than some of the conventional engines. Can understand this point, Atkinson cycle to understand Qi Cheng. When
In 1882, James Atkinson invented an engine, and then Otto-cycle engine is different is that this engine compression stroke and power stroke, the piston displacement is not the same. As we all know the work process is divided into the engine intake, compression, power, exhaust four stages, four stages of a conventional engine piston stroke it is the same, and the Atkinson cycle is how to do different work stages and compression stroke it?
Atkinson engines use a more complex link as a power output from the crankshaft to the piston, the actual stroke of the piston as shown
