It depends largely on just how small an engine you are talking about, and how many cylinders it has. A car with 4cylinders for example may idle at around 1,000RpM, whereas a motorbike with 3 should idle at closer to 1,300RpM.
You can generally tell if an engine is idling at the correct speed by the sound of it. If it sounds like it's going to fast, it probably is. If it stutters or dies, chances are it's idling too slowly.
Very small engines, such as those found on lawn mowers or chainsaws, etc are a bit trickier to adjust, as their operating temperature is attained faster due to their size. Generally these engines should idle slightly faster than is necessary to keep them running.
It may take several days, even weeks of constant adjustment & testing to any engine before it will idle at its correct speed. If you have a manual for a particular engine it should tell you exaclty how to set the adjustable parts (needle valve clip, spark plug gap, timing, points gap, main and sub-jets, mixer screw, etc). It helps if all these are adjusted correctly to begin with, as re-adjusting one thing may make something else perform worse.
It is 3600 RPM
No it did not, But it did like to spen rod bearings at high RPM. Oiling problem
Standard transmision, 750 rpm. Automatic transmission, 600 rpm in drive.
that isn't always true. however, smaller engines are made towards higher rpm's. and also rev up faster. larger engines are more for torque, and smaller engines are more compact and for lighter cars.
there is no RPM settings for a chain saw, it is controlled by the gas trigger, when cutting wood run it full throttle, the rpm settings for stihl varies depending on the model of the unit. all stihl products have an idle rpm setting and wot rpm setting
Horsepower is calculated from RPM and torque. The higher the RPM you can sustain an engines torque at, the higher the Horsepower. Horsepower and Torque are always the same amount at 5250 RPM with all but diesel powered engines. Also the more rotational mass you can spin at a higher rpm, the more energy it poseses.
It is 730 RPM +or - 50
its to do with the air/fuel intake valves F1 cars have RPM of 18000 meaning they run at high revs for acceleration and sheer horsepower low RPM 6000 engines are purely for economical and safety purposes as used in roads cars
Diesel engines have much more torque at low rpm.
(i) Reciprocating spark ignition engine 60 to 90 rpm.(ii) Rotary spark ignition engine 150 to 180 rpm. (Hi) Diesel engines with glow plugs 60 to 140 rpm. (iv) Diesel engines without glow plugs 100 to 200 rpm.
Torque is the force that causes rotation measured in pounds/feet. The more torque, the more rapid the acceleration to the achieved speed. Maximum torque varies from engine to engine based on engine size, and aspiration (turbo vs non- turbo) . In short stroke crankshaft smaller engines, torque occurs at a higher RPM (3,000-4000 RPM) and the transmission should be in the proper gear ratio to allow the engine to achieve that goal. On long stroke engines, usually big truck Diesel engines, maximum torque occurs at a much lower RPM (1,500-2,000RPM) and is limited in it's power band of useful power. That is why large engines have a lot of gears to keep the engine in it's designed RPM power range to do useful work to achieve it's speed goals.
Due to the newer carb standards their is no universal rpm or settings for a weedeater you would have to contact a service center to look up the settings for your weedeater, they also normally take a special tool nowdays that you would have to have to adjust it.
