Applicable to Cummins M11QSMISM engine Jiankebo solenoid valve 3871711

      JackBrake engine brake device is a set of vehicle deceleration equipment, its main working principle is to change the engine exhaust valve valve phase, so that the vehicle deceleration. At the end of the compression stroke, the exhaust valve is opened, so that the work done by the engine when it compresses the air in the cylinder is released to the exhaust system, and the energy is not returned to the piston, and the impulse of the vehicle is transmitted to the engine through the wheels and the transmission system, and becomes the only power for the operation of the anti-drag engine.

      Essentially, the JackBrake turns an energy-producing diesel engine into an energy-absorbing air compressor. This transformation is carried out by a set of electrically controlled hydraulic equipment, triggered by an electric current, and completed under the condition of hydraulic lock. The engine brake can be mounted on the cylinder box or built into a rocker arm system, which is mechanically activated by the engine's rocker arm. If the power switch on the instrument panel is in the on position, the engine brake is activated as soon as the driver releases the accelerator pedal when the clutch is engaged. When the driver uses the service brake, the engine brake device will also maintain its braking effect, so that under the combined action of the JackBrake engine brake device and the vehicle service brake, the vehicle will obtain the maximum deceleration effect.
