What causes diesel engine to surge?
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.
What is pulse type turbocharger?
PULSE TYPE TURBOCHARGING :- IN PULSE SYSTEM, MAXIMUM USE IS MADE OF THE ENERGY IN THE EXHAUST GAS DURING THE BLOWDOWN PERIOD, BY DESIGNING THE EXHAUST VALVES SO THAT THEY HAVE THE LARGEST POSSIBLE PORT AREA. THE EXHAUST CAMS ARE DESIGNED TO GIVE THE MOST RAPID POSSIBLE OPENING OF THE EXHAUST VALVE.
How bad is turbo surge?
Since the turbo is actually making significant boost, is at high RPM, and the pressure is fluctuating wildly because of the surge, these conditions do have the potential to cause greatly accelerated turbo bearing wear and/or damage to the compressor wheel.
What causes turbo chatter?
Essentially, the noise is caused by what is known as “reversion”. When a turbocharged vehicle builds up boost, and the driver backs off the throttle, the throttle body snaps shut, but the turbo is still spinning, trying to compress air.
What does engine surging mean?
Engine surging is when an engine starts easily and accelerates smoothly, however after a few minutes at a steady speed, it either surges in speed or misfires. Misfiring happens when one of the cylinders of an engine’s combustion cycle fails.
How do I know if my turbo is working?
The most common signals that you may have a blown turbo are:
- The car has noticeable power loss.
- The acceleration of the car seems slow and noisy.
- The car doesn’t easily maintain high speeds.
- There is smoke coming from the exhaust.
- There is an engine fault light on the dashboard.
How often should you clean your turbo?
For severe problems and faster cleanup, fill the fuel filter and add the remainder of contents to 100L of diesel fuel. Use at least once a month to keep the turbocharger in optimal condition. Don’t worry about over-treating. This is a case where more is better.
What is labyrinth seal in turbocharger?
The bearings are separated from the blower and turbine by labyrinth seals. These seals are sealed by air supply from the discharge of blower to prevent oil entering the blower and to prevent contamination of the oil by the exhaust gas.
What is axial flow turbocharger?
>> Axial flow turbochargers are similar to gas turbines and are common in aircraft engines. >> Axial flow compresses air into increasingly smaller spaces using a series of impeller or axial compressor fans. Yet they are more efficient than centrifugal or radial turbochargers. …
What is turbocharger surging in ships?
:- Turbocharger is the most vital part of the propulsion system of any ship known to mankind and turbocharger surging is a phenomenon which is responsible to affect the performance of the turbocharger directly and reduce its efficiency. [ Types of Turbocharger ]
What is a turbo surge?
Other terminologies such as turbo surge or engine surge may also be used to describe this phenomenon, but the directly involved component in surging is the compressor of the turbocharger or the turbo-compressor. The turbine side or exhaust gas side of the turbocharger does not play a direct role in the surging process.
Why is the efficiency of a turbocharger highest near the surge line?
The efficiency of compressor is highest near the surge line. This means that if high turbocharger efficiency is desired, a compromise between high efficiency or surging needs to be made. Surging leads to a sharp fall in the flow and acceleration of air mainly because of the reversal pressure.
What are the disadvantages of turbochargers?
This means that if high turbocharger efficiency is desired, a compromise between high efficiency or surging needs to be made. Surging leads to a sharp fall in the flow and acceleration of air mainly because of the reversal pressure. This imbalance in the demand and supply also leads to heavy damage of the turbocharger
