The GY6 single is forced-air-cooled, with a chain-driven overhead camshaft and a crossflow hemi cylinder head. Fuel metering is by a single constant-velocity style sidedraft carburetor, [2] typically a Keihin CVK clone or similar. Ignition is by capacitor discharge ignition (CDI), with a magnetic trigger on the flywheel.
Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel. [1] These have the largest radius rotating at crankshaft speed and therefore are the place where marks at one degree intervals will be farthest apart.
Dieseling or engine run-on is a condition that can occur in spark-plug-ignited, gasoline-powered internal combustion engines, whereby the engine keeps running for a short period after being turned off, drawing fuel through the carburetor, into the engine and igniting it without a spark.
A pair of poppet valves bent by collision with a piston after timing belt failure. The engine was running at 4500 RPM. In interference engine designs, replacing a timing belt in regular intervals (manufacturers recommend intervals ranging from 60,000 to 104,000 miles (97,000 to 167,000 km)) or repairing chain issues as soon as they are discovered is essential, as incorrect timing may result in ...
The comical element only intensified when Jason stood up and declared, “Whoops!” “Oh my God, it was so funny and I couldn’t laugh,” Kylie said on the podcast while hysterically laughing.
Pre-ignition (or preignition) in a spark-ignition engine is a technically different phenomenon from engine knocking, and describes the event wherein the air/fuel mixture in the cylinder ignites before the spark plug fires.
The GY6 might be 15 degees off horizontal. The GY6 may be a honda clone, but it sure as heck not a clone of the elite/spacey 125cc scooter engine. Somebody needs to check their facts. 21:14, October 15, 2006 —Preceding unsigned comment added by 68.215.40.190 (talk • contribs) This is a picture of a 150cc GY6 engine:
