Compression brake actuation system and method |
摘要 |
<p>Compression brake systems using "back-fill" between combustion cylinders or requiring an exhaust valve to be opened twice during a braking cycle require brake actuation systems able to maintain control over the exhaust valve during different loading conditions. In a first opening event where a piston is at or near bottom dead center, pressures in the combustion cylinder are low. During a second opening event near top dead center pressures are higher. Movement of the exhaust valve is controlled by delivery of fluid to a brake actuator piston. Fluid delivery is slowed as the brake actuator piston moves to cover a first cylinder port and uncover a second cylinder port. <IMAGE></p> |
