Next, the spark plug ignites the fuel mixture, sending the piston back down to bottom dead center. The four cycles are:. Cookies make wikiHow better.
The crankshaft spins, and the connecting rods pull and push. This is measured in degrees of rotation. How much does it cost to adjust the timing on a motor?
Then tighten the distributor back into place. Electronic systems may be of the inductive discharge or capacitive discharge type.
The "screwdriver" tip is then touched to whatever is being tested for voltage -- if there's power, the test light will show results by illuminating a small light bulb embedded in the handle. This symphony plays itself out thousands of times every minute as you drive down the street.
Injector, cam camshaft sensor, and spark plugs have already been changed. At this point the spark plug fires and ignites the air-fuel mixture, causing the piston to be pushed back down to the bottom of the stroke.
Tips Clean the timing mark index on the harmonic balancer and mark the top dead center mark with a white or yellow paint marker to make it easier to view. First, it sucks in air and fuel.
Luxury Sedans Sponsored Listing. When set, the ignition system and engine are timed so the fuel in a cylinder is at its peak burn just as the piston compresses the fuel vapors into the smallest amount of space. My Tata indica lsi 2007 model idles high and takes up to 10 minutes to come down to normal. At this point, the crankshaft has turned one and a half full rotations. All modeled in 3D We've created the most detailed 3D model ever produced so we can show you everything working.
Continue rotating until the timing mark is in the correct position. Every part explained There's ridiculous detail on every part. It carries only a very small current, which is fed to a power transistor which switches on and off the heavier LT current to the coil.
