1600 = 5 atdc
Intake Valve open 64 Degree BTDC and closes at 34 Degrees BTDC. Exhaust valve opens at 36 or 37 Degree's ATDC and closes at 79 Degrees ATDC
Arbitrary Time-Dependent Current
In mechanical terms, ATDC stands for "After Top Dead Center." It refers to the position of a piston in an internal combustion engine when it has moved past the highest point in its stroke (top dead center) and is descending. This measurement is crucial for timing the ignition and fuel injection events to optimize engine performance and efficiency. Understanding ATDC helps engineers design and tune engines for better power output and emissions control.
10 degrees btdc with spout connector unplugged.
it is 12 atdc for the 88, I assume they are the same
19 degrees BTDC, + or - 1 degree at WOT. Around 4 degrees ATDC idle timing.
5 deg atdc --------------------------------------------------------------- Motorcraft.com shows the timing on a 1986 Ranger 2.3 L as 10 degrees BTDC
With a timing light of course. Your crank pully should have 2 marks on it, the first mark is for the leading plugs and is 5 degrees AFTER top dead center (atdc) and the second mark is for trailing and is 20 degrees AFTER top dead center (atdc). Your 85 should have vacuum advance on your distributer, be sure to unplug the vacuum line and cap it off while stetting your timing. Trust me when I say, use only your timing marks, playing with your timing on rotaries causes all sorts of problems
After disassembling to expose timing belt, look for TDC and ATDC timing marks. Align them, allowing 43 centimeters. Set BTDC mark in like manner.
