Eccentric Rocker arm shaft Valve adjustment- this allows valve clearance to be adjusted externally, without having to create access into the camshaft area, similar to later Honda TR200 ATV. The advantage is not only time saved, but also no parts/shims or feeler gauges necessary.
A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower. This clearance prevents the parts ...
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.
The valve timing of a diesel engine also depends on tappet clearance of the inlet and exhaust valves. If tappet clearance is less, then valve will open early and close late. [2] If tappet clearance is more, then valve will open late and close early. Tappet clearance is measured by an instrument called feeler gauge.
Leakage in narrow clearance, spool valve. Hydraulic clearance. Flow in narrow clearances are of vital importance in hydraulic system component design. The flow in a narrow circular clearance of a spool valve can be calculated according to the formula below if the height is negligible compared to the width of the clearance, such as most of the clearances in hydraulic pumps, hydraulic motors ...
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
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:
Camless valve trains have long been investigated by several companies, including Renault, BMW, Fiat, Valeo, General Motors, Ricardo, Lotus Engineering who developed electro-hydraulic valve actuation in the late 1980s as a spinoff of their active suspension program (both utilised similar electro-hydraulic actuation and control), Ford, Jiangsu Gongda Power Technologies, and Koenigsegg's sister ...
