Is 6000 rpms too high?
Some engines with a long stroke will destroy themselves if you rev over 4,000 rpm. Some engines can rev up to 10,000+ rpm with ease. Essentially 6,000 rpm on some engines is completely fine, and on others is impossible.
Is high revs bad for engine?
Maintaining higher RPM not only increases the temperature of the engine but also degrades the quality of the engine oil and which results in frequent oil changes. Also, the life of the engine deteriorates when it is continuously abused by the driver by red lining it in the shorter gears.
What should resistance be for idle control motor?
Connect an Ohm meter to the two and measure the resistance between them. Fords are designed to operate with the resistance in the solenoid in a range between 7.0 to 13.0 ohms. If the resistance is outside that range, the idle control motor needs to be replaced.
Can a bad distributor rotor cause an engine misfire?
Engine misfires can occur for a number of reasons. Checking your distributor rotor and cap to see if they need to be replaced is one way to ensure that everything is in solid working order.
Why does the flame not expand across the bore?
When the mixture is lean, the flame cannot expand across the cylinder bore since it requires both fuel and oxygen to accomplish this. In most instances, the flame does begin since the air-fuel mixture by design is concentrated around the spark plug electrode.
Can a weak ignition system cause an engine to misfire?
For an engine to start and run properly, the energy must arc the plug and keep that arc going until all of the combustible mixture is consumed. Anything less and the engine will be weak, run rough, stall, and misfire. Weak ignition is often confused with a fuel problem since the two systems are codependent.
How many times does each cylinder fire per second?
A 1,000cc 4-stroke engine with 4 cylinders is running at 1k RPM. How many times does each cylinder fire per second? How can this be calculated? Also, does the piston provide force to the crank shaft with each stroke, even during the exhaust stroke?
Why does the RPM of an engine matter?
An internal combustion engine is an air pump, and if we turn that pump faster, we can theoretically burn more fuel in a given amount of time and consequently produce more power. For example, an eight-cylinder engine running at 6,000 rpm fires its cylinders 24,000 times in one minute (assuming perfect combustion).
Are there engines that run at high RPM?
However, with the technology developed in NASCAR and in Pro Stock, racers are learning how to build engines that operate reliably at high rpm. Research and development on valve materials, springs, rocker arms, and pushrods are now being applied to serious sportsman drag racing engines.
How many RPM does a 500cid stock engine turn?
It’s difficult to believe that 500cid Pro Stock engines now routinely turn 10,000 rpm, but the truth is plain to see on the data recorders and on the time slips.
