For the tests the vehicle brake for which the replacement linings are designed is installed in an inertia dynamometer instrumented for continuous recording of rotative speed, brake torque, brake line pressure, number of rotations after brake application, braking time, and brake rotor temperature.
A DC injection brake system can be used as an alternative or addition to a friction brake system. DC injection brakes only require a small module located with the other motor switchgear and/or drivers, mounted in a remote and convenient location, whereas a friction brake must be mounted somewhere on the rotating system. Friction brakes ...
Maximum brake torque (MBT) is the use of optimal ignition timing to take advantage of an internal combustion engine's maximum power and efficiency. There is always an optimal spark timing for all operating conditions of an engine. MBT is ideal at wide-open throttle (WOT), but not desirable when the engine is at idle.
A compression release brake (also known as a Jacobs brake or "jake brake"), is the type of brake most commonly confused with real engine braking; it is used mainly in large diesel trucks and works by opening the exhaust valves at the top of the compression stroke, so the large amount of energy stored in that compressed air is not returned to ...
The brake system for FE is similar to the rest of the FM/FH family of trucks with EBS however a new integrated air dryer system called APM or Air Production Management was introduced. APM combines the functions of air dryer, regulator, four-way protection valve, pressure limiting and safety valves, pressure sensors and blocking valve into one ...
The government will require heavy trucks and buses to include automatic emergency braking equipment within five years, the federal traffic safety agency said Thursday, estimating it will prevent ...
The driver requests the torque or engine speed requirements via accelerator pedal potentiometer thereby sending a signal to the engine ECU which then, depending on its mapping and data collected from various sensors, calculates in real time the quantity of injected fuel required, thus altering the fuel rack to the required position.
The UGN U 300 has a combined hydraulic/pneumatic braking system; all other models are equipped with a solely pneumatic braking system. The Unimog 405 has disc brakes on all wheels, and automatic load-dependent brake force control (ALB) as well as anti-lock braking (ABS). [25] The parking brake is spring-loaded, and acts on the rear wheels. [31]
