Engine Pinging Engine pinging also refered to as pinking, detonation or knocking Pinging can be anything from a loud knocking noise to a soft tinkling sound that is emitted from the engine. If an engine has a tendency to ping, it usually becomes first audible when operated in the lower rpm range and during acceleration. Pinging tends to fade away with increasing engine revolutions. What causes pinging?

Selecting the Right Octane Fuel Using a lower octane fuel than required can cause the engine to run poorly and can damage the engine and emissions control system over time. It may also void your warranty.In older vehicles, the engine can make an audible knocking or pinging sound.sing a lower octane fuel than required can cause the engine to run poorly and can damage the engine and emissions control system over time. It may also void your warranty.

- The engine “pings” or knocks on acceleration. The symptom is more pronounced when the engine is at operating temperature. Engine ping is the result of abnormally high combustion temperatures. The usual cause of engine ping is over advanced ignition timing, an inoperative EGR system or improper fuel usage.

Ford Focus Surging/Bucking Between 40 and 50 MPH Recently, it started surging and bucking between 40 and 50 MPH. Seems to run fine under acceleration, but then when backing off the accelerator, it starts the surging/bucking. The check engine light is on constantly.

What is ping? Ping is a measure of your connection speed or, more specifically, the latency of the connection. Here we'll explain ping in more depth, how to measure ping speed and how to reduce ping and improve lag in online games.f you have a ping of 98ms (milliseconds) that's the time it has taken for your computer to respond to a request by another computer. See also: Best gaming PCs of 2015. Clearly, you want as low a ping time as possible. Many online games show your ping time along with the ping of other players or servers.

What Causes Engine Knocking What Causes Engine Knocking Posted on Autos.com Editor. in Car Maintenance. on October 7, 2013. Engine knocking, or pinging, is a term often used to describe an irregular sound made by a vehicle engine when there is a problem with the handling of air/fuel mixture within the cylinders. Normally, this sound is heard when the vehicle is idling and it can be either weak or strong.

what does ping mean? Ping stands for ping (not an acronym). Ping is actually the slang name for an ICMP echo request. The idea is to send out a packet that requests a reply from the destination and monitor how much time in millisecond(ms) it take to return to the sender. This does NOT effect speed, but can effect things like response time form sites and online games.

ping (networking utility) Ping operates by sending Internet Control Message Protocol (ICMP/ICMP6) Echo Request packets to the target host and waiting for an ICMP Echo Reply. The program reports errors, packet loss, and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard deviation of the mean.

"What is ""ping"", ""download speed"", and ""upload speed""?" What is ping, download speed, and upload speed? The ping is the reaction time of your connection–how fast you get a response after you've sent out a request. A fast ping means a more responsive connection, especially in applications where timing is everything (like video games). Ping is measured in milliseconds (ms).

Oxygen Sensors|O2 Sensor | Diagnostics If a bad oxygen sensor is aligned with the ignition system on a car's engine, it can retard or advance engine ignition timing, which can cause an engine to ping.ough Engine Idle Vehicle engines that have a bad oxygen sensor often run irregularly or roughly. Oxygen sensors can control or contribute to many different engine functions, including fuel/air mixture, engine timing and engine combustion intervals.

High Octane Fuel Is Better There is a misconception in the world that high octane fuel will make your car go faster or run better. This isnot true. The octane rating only rates the fuel’s resistance to engine knocking. Knocking or pinging is a sound that an engine makes when the air-fuel mixture in the combustion chambers ignites too early.

What would make loud acceleration motor sound while driving, but quiet at idle? The noise started with acceleration and sounded like an engine revving up and sounded like it was decelerating as it slowed down. It was a consistent noise. Loud enough to sound like having glass packed mufflers on the inside of the car. You could not hear it from outside the car as it drove past.

"What Does It Mean When an Engine ""Knocks""?" Knocking in your engine, also described as pinging, can be related to one of several problems. Some may be easily fixed while others may indicate major damage. The knocking sound often occurs when the fuel and air mixture is incorrect, which causes the fuel to burn in uneven pockets rather than uniform bursts.

- 1 Vacuum leak, again like above. 2  Fuel delivery issues, like clogged fuel filter or weak fuel pump will sometimes cause an engine to chug and stall at low speeds.  Base engine issues, like cam/crank timing can really cause erratic behavior at all engine speeds, but again may be more noticeable at a stop.

Uploading and Downloading Online: The Basics What does it mean to ping something? A ping is a term used to refer to a tool that checks to see if a website is down or not. In the context of Web search, pinging a Web site basically means that you're endeavoring to determine whether a specific Web site is having issues; it could also help narrow down connectivity problems when you're attempting to upload or download something.

- The best place for wide-open throttle (WOT) air/fuel testing is at the dragstrip. Short of that, you can do Second-gear bursts of 2 to 3 seconds each and have a passenger watch the meter. For your initial work, you should shoot for WOT air/fuel ratios between 2.5:1 to 13.0:1.he engine responded with a slightly richer mixture in light acceleration of around 13.2:1, but we still had a slightly rich cruise air/fuel ratio. When we tried larger (leaner 52B) primary metering rods, it hurt light-throttle acceleration.

- engine hesitation on acceleration. when I press on gas the engine hesitates as if it's going to stall and the acceleration takes effect only after 2 seconds or around there, don know why! any response appreciated. Ooh yeah the check engine light is also on. :banghead:

Car hesitates when accelerating Fuel Pipe. One common problem that an internal combustion engine hesitates is bad fuel pipes. Check all the fuel pipes from the fuel tank to the fuel system including those small pipes around the fuel system. It is not surprise that sometimes rats had entered into the bonnet and chewed some of the fuel pipes.

- Yes. And, on engines that do not have a Mass Air Flow (MAF) sensor, the MAP sensor signal is also used by the PCM to calculate engine load -- how hard the engine is working. This is called the speed-density method of calculating engine load for engines without MAF sensors.

What is engine knock? When fuel is improperly ignited, it causes a fireball-like explosion that can interfere with the engine's cycles and can even damage engine components -- these premature detonations are the source of the ping noise. Now, let's look at the most common causes of knock. Low quality fuel.

Why Does My Car Sputter When I Hit the Gas? Look at the intake hose for cracks because if the system is not airtight and a car has a mass air flow sensor, sputtering at acceleration is one possible sign. Repair any air leaks that are present and then test the engine again. The reason why air leaks cause sputtering is that the air-to-fuel ratio is hampering the performance of the engine.
