A Honda K24A Engine with i-VTEC. VTEC (described as Variable Valve Timing & Lift Electronic Control, but stands for Valve Timing Electronically Controlled) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM.
Since those days, lift, velocity, acceleration, and jerk curves for cams have been modelled by computer [6] to reveal that cam dynamics are not what they seemed. With proper analysis, problems relating to valve adjustment, hydraulic tappets , push rods, rocker arms, and above all, valve float , became things of the past without desmodromic drive.
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.
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 ...
In late July, Super Micro's auditor at the time, Ernst & Young (EY), raised concerns about the company's governance, transparency and internal control over financial reporting, prompting its board ...
Another feature of the i-VTEC system on the TSX and RSX-s was that, unlike other Honda K-series motors, variable timing was used on both the intake and exhaust cams in its three rocker design. For the 2006 model year, the K24A2 was updated to produce 205 hp (153 kW). The diameter of the throttle body and intake valves were slightly increased ...
