When to use dynamometer to test engine performance?
The dynamometer must have the capability to test the performance of the engine when the engine is operating at the maximum RPM and horsepower range (full power). The engine crankcase pressure, often referred to as engine blowby, is an important factor that indicates when the piston rings have achieved…
Can you drive with a bad mass air flow sensor?
You can drive with a bad mass airflow sensor, but you shouldn’t as it can lead to the damage of other engine components and your vehicle will use a lot more fuel than it should, especially at higher speeds.
What kind of diagnostic system does Mercedes R129 have?
For those fortunate to own post 1999 vehicles of the R129 stable your car should be equipped with a fully compliant OBD2 diagnostic system, 16 pin standard diagnostic port and the capability to be interrogated by most any off the shelf OBD2 reader. (Lucky you!)
What should the idling speed be on a Stromberg engine?
For most cars it should be 850-950 rpm – judge it by ear if your car does not have a tachometer (or rev counter). Adjust the idling speed by turning the throttle-stop screw. If tuning fails to make the engine run properly, the carburettor may need cleaning (See Air filter change ), or the air filter renewing.
Can you measure engine rpm with a multimeter?
If your multimeter has a HZ or FREQ function, with the right amount of fussing and experimentation, you may be able to calculate engine RPM’s from the HZ or FREQ readout.
What kind of light does a RPM meter use?
Tape Tabs (Sheet of 35) Shine a bright flashing light at a moving object to make it appear slow moving. Use to measure speed and to visually inspect belts and pulleys for signs of wear, such as cracking and fraying, without turning off the machine. This unit has a 1/4″ -20 female threaded bushing for tripod mounting.
How to monitor your rpm gauge to get the best performance?
A car tachometer, or RPM gauge, shows the speed the engine is spinning. Watch your RPM gauge to improve your car’s performance and fuel efficiency. When you start your car, the crankshaft inside the engine begins to turn. The engine’s pistons are connected to the crankshaft, and they rotate the crankshaft through their up and down motion.
What does the Red Line mean on the RPM gauge?
The highest RPM range at which you start to run the risk of seriously damaging your car’s engine , referred to as the red line, is marked in red color on the RPM gauge. Exceeding an engine’s red line can result in significant engine damage especially over extended periods of time.
