When should I use an engine retarder?
A retarder is a device used to augment or replace some of the functions of primary friction-based braking systems, usually on heavy vehicles. Retarders serve to slow vehicles, or maintain a steady speed while traveling down a hill, and help prevent the vehicle from “running away” by accelerating down the hill.
What is Scania retarder?
Scania Retarder is a hydraulic system that is integrated into the output end of a truck’s gearbox and uses high-pressure oil as a braking medium. Via a gear transmission, the Retarder acts on the output shaft of the gearbox and thus directly on the propeller shaft.
What oil goes in a Scania Retarder?
Retarders: – Scania Retarder May also use CASTROL TRANSYND, CASTROL TRANSMAX OFFROAD 10 or CASTROL TFC 410.
How does a retarder work?
An engine retarder captures the exhaust from the engine and compresses it so that the engine must work harder to push the gas out of the cylinders, and it therefore retards and slows the engine through resistance.
What are the 4 types of retarders?
Retarders are mechanisms in some vehicles that help slow the vehicle and reduce the need for braking. The four basic types of retarders are exhaust, engine, hydraulic, and electric.
Do retarders keep you from skidding when the road is slippery?
Q: Retarders keep you from skidding when the road is slippery. True or False? A: False. Your wheel may skid when roads are wet.
How does a retarder work on a truck?
Engine retarder brakes are used in many heavy trucks as a supplement to the vehicle’s service brakes. The principle behind the engine retarder brake is that it changes the action of the exhaust valves, turning the engine into an air compressor. Reduced wear on engine, tires, and service brakes.
How does a diesel exhaust brake work?
So, how does an exhaust brake work? Essentially, it works by trapping engine pressure in the exhaust system, which in turn forces the engine to rotate slower (backpressure). Normally, pistons travel upward in their cylinder bore to force spent exhaust gasses out of the engine via the exhaust valve.
What oil goes in a Scania retarder?
What oil goes in Scania gearbox?
Mobil Delvac 1 5W-40 is a fully-synthetic diesel engine oil with Scania LDF oil approval. Suitable for Scania Euro II or Scania Euro III engines requiring extended oil drain intervals, Mobil Delvac 1 5W-40 delivers both exceptional performance and outstanding high and low temperature protection.
What should I do if my Scania retarder fails?
The yellow indicator on the instrument cluster is on. If the control unit software update fails, try the update again. Otherwise, erase all fault codes, stop and restart the car engine. If the DTCs continue to display, replace the control unit.
What are the diagnostic codes for Scania transmissions?
Scania diagnostic trouble codes (DTC): Transmission (GMS) and Retarder (RET) Control System 1548413, 1724590, 1757823, 1763365 Control block Incorrect or unreliable data. Internal malfunction. No retarder braking is possible. The yellow indicator on the instrument cluster is on. If the control unit software update fails, try the update again.
When is the fault code deleted on a Scania?
Gear shift adaptation is disabled. The DTC can only be set when the engine speed is more than 200 rpm. This DTC can be set by setting DTC 1809. The fault code is deleted automatically if the car has gone through 40 startup cycles, during which the fault was not registered again.
When to set a fault code on a retarder?
The reason for setting this fault code can be long driving and / or driving in difficult conditions without blocking, or prolonged braking by a retarder. This DTC is set if the oil temperature exceeds 126 ° C for at least 10 seconds. This code can also be set as a result of valve sticking. Allison DTC: P0218.
