A long exhaust stroke then extracts maximum efficiency. The in-cylinder gases are thus expanded and cooled as the piston descends, before being re-compressed as the piston rises again. Early closure of the inlet valves leaves a smaller window for the charge fill the cylinder. Magma boost system layout. 2016) Click to enlarge.
