  • US20150034047A1 - Control device for internal combustion

    Oct 16, 2019 · An object of the invention is to provide a control device for an internal combustion engine that regularly and forcefully removes deposit that is accumulated in cylinders and restrains consecutive occurrences of pre-ignition beforehand. The internal combustion engine has a low-speed pre-ignition region in which a possibility of occurrence of pre-ignition increases, in a low-rotation and high

    Jul 08, 2004 · I was trying to remember but not sure. I show to be running around 32 BTDC maybe as high as 37 when off lite throttle. 0-30 = 41. 30-60 = 35. 60-90 = 34. 90-120 = 32. 120 - 150 = 27. this is around 3500rpm, the left column is kpa and the right is actual timing.

    This is not the case for diesel engines. Diesel engines do not use spark plugs; turning off the engine ignition switch does not shut down the ignition source. Stopping the fuel supply is also ineffective because the fuel is present in the intake air. The only way to prevent mechanical failure and

  • Understanding Ignition Timing and it's effect on your engine.

    Nov 15, 2019 · Ignition timing curves are usually not just a liner line. As engine speed increases so does the timing requirements. Most of the time the ignition will advance the most at lower speeds. Usually by the time the engine is at 3000 rpm it will have 60% of its total advance already in.

  • Signs and Symptoms of Spark Plug Problems

    Jul 27, 2019 · How the Spark Plug Works . Fire requires three components: oxygen (O2), fuel, and heat.In your engine, every time a cylinder pulls an intake stroke, it pulls in air (≈21% O2).Port-injection engines inject fuel during the intake stroke, while direct-injection engines, gasoline or diesel, might wait until the compression stroke. Finally, heat is provided in one of two ways: one or two spark

  • Engine Hesitation Problem: Car Hesitates When Accelerating

    Hesitation is when the engine stumbles, misfire or when you step on the throttle or you accelerate it lacks of power. The issue occurs most generally due the air/fuel mixture is going lean or isn't being enriched properly. Or when the air/fuel mixture going to lean or the engine comes under load, the ignition system is weak and misfiring.

  • Understanding Ignition Timing: Making Maximum Power Means

    Sep 01, 2017 · In a spark ignition internal combustion engine, the purpose of advancing the timing of the engine spark is to get past ignition delay. Ignition delay occurs during the time that it takes to fully ignite the mixture with a spark plug. That is typically 15-35 degrees before TDC (top dead center) of the power stroke depending on the engine speed.

  • How engine timing works | How a Car Works

    For an engine to work at its best, the fuel /air mixture in each cylinder must fire just as the piston reaches top dead centre ( TDC). It takes a certain time for the spark-plug to ignite the mixture and for the combustion to build up. This time stays roughly the same no matter how fast the engine is running. The timing mechanism is set to fire the plug a short time before the TDC.
