HOW IT WORKS

The Diamond Logic Engine Brake is a bleeder brake – it holds the exhaust valve off of its seat to bleed off compression while overcoming backpressure produced by the turbocharger vane turn-down system. While bleeding the compression against the backpressure, a pumping loss is created, converting the vehicle’s rolling momentum into retarding power.

During deceleration, with the Diamond Logic engine brake switched on, the EVRT Vane Turn-Down optimumizes exhaust backpressure and high intake boost at any engine speed. Simultaneously, the Diamond Logic engine brake deploys actuator pistons onto the exhaust valve bridges to hold open one exhaust valve per cylinder. Once fully-deployed, the actuator pistons will hold open the exhaust valves through all four engine strokes until the driver steps back on the accelerator, or the engine reaches idle speed. Once deactivated for acceleration or idling, the bleeder brake pistons retract and allow the exhaust valves to function normally for combustion cycles.
