Hyundai I20 2017 Exhaust Camshaft: High-Quality Replacement Part

Genuine Hyundai I20 2017 Exhaust Camshaft (Part #2420003010) – MOBIS/GENUINE, Korea – Brand New, Guaranteed Quality, Best Price

The Hyundai I20 2017 exhaust camshaft is a crucial engine component responsible for precisely controlling the intake and exhaust valve timing. This vital part receives rotational energy from the crankshaft, typically via gears, belts, or chains. The camshaft’s rotating motion, facilitated by its precisely shaped lobes, opens and closes the valves, ensuring optimal engine performance.

The camshaft’s location varies depending on the vehicle’s design. The position sensor, which monitors the camshaft’s position, might be adjacent to the rocker arm or integrated into the rocker arm cover. Modern gasoline engines often place the camshaft atop the cylinder head. Depending on its placement, the camshaft may directly actuate the valves or use intermediary components such as pushrods and rocker arms. This arrangement enhances operational efficiency and reliability, but necessitates a camshaft located at the cylinder head. In piston-driven internal combustion engines, its primary role remains the precise control of valve operation.

This component comprises a cylindrical shaft extending the length of the cylinder bank, featuring several precisely shaped cam lobes. The camshaft is supported by bearings integrated into the cylinder head, allowing for lubrication and stable operation. These bearings, which possess oil passages, ensure proper lubrication and secure the camshaft using specialized shims.

Understanding the Exhaust Camshaft’s Function

The exhaust camshaft is an integral part of the internal combustion engine’s valve train. Its primary task is the controlled transfer of energy, optimizing engine efficiency and performance. Synchronized with the crankshaft (generally at half its speed), it governs exhaust valve operation. Fundamentally, the camshaft comprises three key elements: intake cam lobes, exhaust cam lobes, and bearing journals. The lobes are strategically arranged according to the engine’s cylinder firing order. The precise height and profile of each lobe dictate the valve’s lift and duration, impacting engine performance.

Its functions encompass: precise timing of intake valve opening during the intake stroke, controlled opening of the exhaust valve during the exhaust stroke, and the simultaneous closure of both valves during the remaining engine cycles.

As mentioned previously, the camshaft’s location isn’t standardized across all car models. Its position sensor placement varies accordingly, often near the rocker arm or on its cover. In contemporary gasoline engines, its typical location is at the top of the cylinder head. Whether directly activating the valves or through intermediaries, this design prioritizes ease of use and reliability while mandating its position at the cylinder head.

In short, within piston-driven engines, the camshaft is essential for valve actuation. It’s a cylindrical component, running parallel to the cylinder bank, with multiple precisely-shaped lobes (cam lobes) that drive the engine valves. Furthermore, integrated bearings with oil passages and shims firmly secure the camshaft within the cylinder head, facilitating reliable operation and lubrication.
