wouldn't it help to build more intake volume/pressure in the cylinder if the exhaust was restriced some? Maybe that's done by the valve opening or duration.
Good question that likely only an old Detroit 2 cycle engineer could answer.
Would restricting the exhaust to allow the blower and turbo to pack more air in the cylinder , overcoming the loss of exhaust scavenging caused by the restriction ??
Remember, the pistons do not push the exhaust out of the cylinders in a 2 cycle Detroit. It's the fresh air blowing in the intake ports at the bottom of the cylinders that pushes the exhaust out of the exhaust valves at the top of the cylinders |
