Driving at 50mph or above what causes a loud knocking clicking sound during acceleration?
ok where is the knocking coming from, brakes, engine ? only happens during acceleration ? if it is truly an engine knock, check oil immediately, but maybe to late, again need more info.
Timing chains will normally last the life of the engine and are replaced during a complete engine rebuild.
One of the causes of a high-pitched whine during acceleration on a 1999 Nissan Maxima is a fan belt that might be a little too tight. A drop or two of any dish soap on the inside of the belt should cure the loud whine. If not, make sure all of the pulleys on the fan apparatus are turning properly.
If a 2006 Nissan Sentra 1.8 Liter will not accelerate by stepping on the gas pedal, it is probably a compression problem. Check the MAP (Manifold Actual Pressure) Sensor. This sensor is responsible for letting the computer know how much pressure is in the manifold when the engine is running. Also check the EFI (Electronic Fuel Injector) or carburetor and the Speed Sensor.
Timing chains are designed to last the life of the engine and are normally replaced during a complete engine rebuild. Unless it becomes noisy no maintenance is necessary.
To calculate acceleration, divide the change in speed by the time during which the acceleration occurs. :)
It all depends on the nature of the 'knocking':Cheap gas - light rattle during acceleration indicating 'pre-ignition' is happening.light knocking all around the engine -low / expired engine oilLow oil pressure - plugged filter to failing oil pumpHard knocking - could be a piston coming lose and banging on the side of the cylinder walls - not good(!)Way too many variables to diagnose over the internet.Have the car inspected by a good, reputable mechanic
That's true throughout any period of time during which the acceleration is constant.
During acceleration? I'm not sure. But when both idling and acceleration the engine's combustion can cause a lot of vibration in the steering wheel if you are in an older vehicle.
Your Nissan may just idle high during the warm up of your engine. These cars are designed to do this based upon the fact the cars have an optimum running temperature. If they idle high when for the first 15 minuets it's to achieve that optimum running temp. If not then you may have a vacuum leak.
It does not affect its acceleration in a vacuum, that is, no air resistance. The acceleration s the acceleration of gravity which is constant
Acceleration means speeding up or slowing down, a change in velocity. Since the velocity was constant, the acceleration was. 0
Dividing change of velocity by the time it takes to change the velocity. If acceleration is not constant, this will give you the average acceleration during the period; to get the instantaneous acceleration, you have to take the derivative of the velocity.
The shift of velocity per unit of given time is called acceleration. The types of acceleration are negative acceleration and positive acceleration.
replace that factory carb. they are junk,dont even try to have it rebuilt,get a webber 32/36
No, it's only the acceleration. By (-)ve acceleration ,it means retardation or deceleration..
Average acceleration during any period of time = (change in speed during that time) divided by (length of the time period).
do u mean that does yor engine move side to side during acceleration. well no because your foot is on the accelerate
sounds like you are using poor quality fuel, fill up with premium and see if it goes away. you may be able to go back to the cheap stuff for a while after.
Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.
It may or may not be true: it depends on the direction in which the acceleration is being measured.
