Manufacturer-specification timing belts may stretch at high rpm, [citation needed] retarding the cam and therefore the ignition. [12] Stronger aftermarket belts will not stretch and the timing is preserved. [13] When designing the timing belt, a wider belt increases its strength however a narrower belt reduces weight and friction. [14]
For twin-cam or DOHC engines, VCT was used on either the intake or exhaust camshaft. (Engines that have VCT on both camshafts are now designated as Ti-VCT.↓) The use of variable camshaft timing on the exhaust camshaft is for improved emissions, and vehicles with VCT on the exhaust camshaft do not require exhaust gas recirculation (EGR) as retarding the exhaust cam timing achieves the same ...
The Volkswagen EA211 engine (EA = development order), also called modular gasoline engine kit, is a family of inline-three and inline-four petrol engines with variable valve timing developed by Volkswagen Group in 2011. [1]
When it was introduced in 1987, the Series 60 was the first heavy-duty diesel engine with fully integrated electronic controls. [2] Detroit Diesel prescribed overhaul intervals of 500,000 miles (800,000 km), then raised that to 750,000 miles (1,210,000 km) after more experience was gained with the new engine.
Honda K24A4 2.4L DOHC i-VTEC Engine installed in 2003 Honda Accord. The Honda K-series engine is a line of four-cylinder four-stroke car engines introduced in 2001. The K-series engines are equipped with DOHC valvetrains and use roller rockers on the cylinder head to reduce friction.
Camshafts normally have one lobe per valve, with a fixed valve duration and lift. Although many modern engines use camshaft phasing, adjusting the lift and valve duration in a working engine is more difficult. Some manufacturers use systems with more than one cam lobe, but this is still a compromise as only a few profiles can be in operation at ...

The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
