timing belt

[′tīm·iŋ ‚belt]
(design engineering)
A power transmission belt with evenly spaced teeth on the bottom side which mesh with grooves cut on the periphery of the pulley to produce a positive, no-slip, constant-speed drive. Also known as cogged belt; synchronous belt.
(mechanical engineering)
A positive drive belt that has axial cogs molded on the underside of the belt which fit into grooves on the pulley; prevents slip, and makes accurate timing possible; combines the advantages of belt drives with those of chains and gears. Also known as positive drive belt.

[ClickPress, Wed Jun 19 2019] Manufacturers in the global Automotive Timing Chain and Belt Market are focussing on the introduction of new application specific product offerings to address customer specific requirements.
Your timing chain experience is not a one-off, according to online reports.
The chain wear test was a fired engine dynamometer lubricant test, which evaluates the ability of a test lubricant to reduce timing chain wear.
(2) Midstream costs include fluid and recommended filter changes for all engines and mid-time gearbox, alternators and timing chains for Continental engines.
Friction losses have also been reduced, notably by using a new low-friction timing chain. And although it's still one of the lightest engines on the market, more weight has been saved by introducing a cylinder head with an ingenious built-in exhaust manifold.
By using Stanyl polyamide 46 (a non-Diablo version) to produce a timing chain guide, the reduced friction can, says Akins, result in a reduction of fuel consumption by as much as 1%.--GSV
It has no clutch; the starter motor and alternator are integrated into the system, so require no servicing or replacement during the vehicle's lifetime; and instead of a timing belt it uses a maintenance-free timing chain.
The network management system (NMS) is responsible for configuring the network including the wavelength ([lambda]) assignment, collecting the mean fiber link delay (D) by the T-BC, and processing the fiber link delay asymmetry (A([lambda])) in (8) to determine the asymmetry compensation in the timing chain. The sum of A([lambda]) in the timing chain can be written as
The inlet and exhaust valves keep opening and closing at appropriate time (with the help of timing chain or belt) to regulate entry and exhaustion of fuel air mixture.
Other features of the engine are a double overhead camshaft, 16- valve layout and a silent timing chain.
The automaker is replacing the engines because of a defective timing chain and guide, which can cause a clattering noise.
The 4.0-litre design includes Electronic Throttle Control with secondary mapping in 4LO (4x4 models), Continuous Variable Valve Timing Control System (CVTCS), Nissan variable Induction Control System (NICS), silent timing chain, microfinished camshaft and crankshaft surfaces, molybdenum-coated pistons and lightweight aluminium block.
