No. of applications: 7
Last issue date: 05/24/2012


Application No.Application TitleIssue Date
20120125298Two stroke opposed-piston engines with compression release for engine braking
In a two-stroke opposed-piston engine, a ported cylinder with a pair of opposed pistons is equipped with a decompression port including a valve and a passage with an opening through the cylinder wall that is located between the cylinder's intake and exhaust ports. The d...
