Usually not. The seals in a rotary that does the job of the piston rings in a piston engine have a much harder job to do, and tend not to last as long.
Agreed. The "Wankel" was a good concept, an engine with one moving part but never lived up to it's potential. The above answer is an excellent example. The trouble mostly came from balancing the rotor, as it did not rotate in a perfect 360 degree circle and oil seals were prone to failure

Which is best Rotary compressor or reciprocating compressor?
Receip or Piston type compressor are used for large duty cycle work (A/c or other equipments), energy hungry but last longer (Heavy Duty). Where as rotary compressor are energy efficient with higher ( Energy Efficiency Ratio) but lower duty cycle and shorter life. Selection of compressor are based on the nature of application. Normally, for room A/Cs with capacity less than 3 ton, most companies offer rotary compressor due to it's EER and less duty cycle. For heavy duty A/Cs, recip or piston compressor best suited.
What is intake stroke in a diesel engine?
In a gasoline engine, it is a fuel-air mixture that is drawn in during the intake stroke, unless the engine is fuel injected. In a fuel injected or a diesel engine, it is air, because the fuel (gasoline or diesel) is injected at the "last moment" before ignition.
How do engines last so long?
There is very little metal to metal contact as the metal parts are separated by a film of oil. Newer EFI equipped engines last longer due to better control of fuel, as they completely shut off the fuel when decelerating, which prevents fuel from washing the cylinder walls .
Find the yield strength from a stress-strain graph?
Follow the graph's positive slope (across the first quadrant) until the graph is no longer linear. The yield strength is determined to be the last point (with concern given to the stress value) on the linear section. After this point the graph is irregular because the material has failed to a point of no return and can no longer handle the load (stress).
How long do Heat Exchangers last?
The average life span of a heat exchanger is roughy 20 to 25 years. Some can and will make it longer some will go after a few days. It is due to the expading and contracting of the metal with the heat involved.
Do you have to repair a rotary engine every 100000 km?
Theoretically the rotary engine could last up to 200k miles but it depends on how hard you drive the engine
If a 1987 RX-7 1.3 B rotary engine has 223000 km's will it last?
yes it will if you maintanance it regularly.
Will my car engine last longer if I replace the cylinder head that is bad and knowing that the engine has 200k?
Yes, the engine probably will last longer but have your mechanic inspect the vehicle to see if the rest of the vehicle will last longer. It may not be worth the expense to repair the engine if the rest of the vehicle needs more $$$$.
How long do starter last on rotary engine?
That all depends on if you abuse the starter by cranking too long. I have 170,000 on original starter.
What mileage do you have to change your timing belt to your Mitsubishi montero sports?
This engine is what they call an "interference" engine. That means unless the valves are closed when the piston reaches TopDeadCenter they will collide and the pistons will bend the valve, driving it into both the cylinder heads and piston crowns with devastating results. Your timing belt is usually rated for 60,000 miles. It may last longer. Waiting for it to fail to save money is not really a good option as when, (not if) it does fail while in service, your engine will be destroyed.
How long do distributors for cars last?
Normally they last the life of the engine or longer. No real guarantee.
How does a 4 stroke engine work?
As the name states there are 4 strokes in a 4 stroke engine. Intake, when the piston draws in air/Fuel mixture. Compression, when the intake valve closes and the piston moves to the top off the stroke. Power stroke, when the compressed mixture is ignited, forcing the piston down. Last the exhaust stroke when the piston starts moving up and expells the burnt gases.
How is car engine classified?
A car engine can be classified based on the number of cylinders it has. It could be a 4 cylinder, 6 cylinder, 8 cylinder, 10 cylinder, or 12 cylinder (the last two engines are mainly used in exotic cars). There are also rotary engines, electric engines, natural gas engines and hybrid (electric/gas) engines. Each of these has subcategories as in the most common piston engines listed above.
Is nitro piston as powerful as the spring and last longer?
This question sounds more like a statement than a question. To try to answer you, you have to understand that Nitro is a fairly new product, it's going to take time to find out which will last longer. It's too soon to tell.
Is an oil cooler necessary on a 350 Chevy?
It don't have to have it. But it will make the engine LAST LONGER.
Who was the last NASCAR driver to win the piston cup?
NASCAR has never had a Piston Cup in any of their series. They did have a Winston Cup and the last winner was Matt Kenseth.
What was the last war using piston engine propellor aircraft?
In 1969. El Salvador and Honduras in the Football War.El Salvador had P51 Mustangs and Honduras flew F4U Corsairs.The above was the last instances of fighter piston aircraft seeing combat. Most militaries continue to this day to use piston engine aircraft for certain specialist duties: transport, forward fire control, observation, COIN, and other light duties. However, even here, most are slowly being phased out in favor of the turboprop.
