Internal combustion engines have a flaw. When the piston reaches the bottom of the power stroke in a traditional four-stroke engine, there is still a high pressure contained within the cylinder. This pressure is released when the exhaust valve opens, ultimately wasting energy. One potential solution is an Atkinson cycle engine, which increases the expansion ratio, relative to the compression ratio, resulting in greater efficiency.

The problem with the Atkinson cycle is that because it reduces the intake stroke length, less air and fuel are drawn into the cylinder, and overall less power is created. In this video, we’ll explore GM’s solution to this problem, which is to create a variable compression ratio Atkinson cycle engine. Check out the video to learn all about GM’s patent!
