A Study on the Engine Brake Character of Crankcase-Compression Two-Stroke Cycle Engines

In a two-stroke cycle engine, it is impossible to except the effect of engine brake, owing to its structure. However, since the necessity of engine brake has increased with increasing the vehicle speed, and with increasing the complexity of traffic problems, it is demanded to solved. For this reason, the authors investigated the mean frictional loss pressure of engine, and the effect of releasers on the engine brake with a crankcase-compression two-stroke cycle engine.

The results, one of the weak points on a two-stroke cycle engine be solved completely by the application of releaser.
