In order to solve problems modular type camshafts have, that is, reducing weight, increasing oil filling time and designing multi-valve system, research was initiated about feasibility for DfE (Desing for Environmrnt) about ultralight camshaft . Through LCA (Life Cycle Assessment) and properties and process evaluation, an attempt has been made to develop cost-effectvie process for ultiralight aluminum camshaft without the problems modular type camshaft have.

Abstract:
This paper presents the structure and static model of engine camshaft analysis. For the purposes of this analysis, the finite element method is used. Camshaft is one of the critical components for effective and precise work of internal combustion engines. This camshaft rotates at high speed causing pressure and vibration in the system. Camshafts are also subject to varying fatigue burden due to cam plunger contact. These precise values are required to be determined to prevent failure in the camshaft. The objective of the project is to model and to perform pressure analysis on the camshaft mach

Camshafts play a critical role in internal combustion engines, dictating the timing and duration of valve opening and closing events. To ensure optimal engine performance and longevity, camshaft design must balance factors such as strength, durability, and weight.

Abstract To analyze the dynamic characteristics of diesel engine camshafts and the factors affecting camshaft speed fluctuations, a multi-body dynamic model for gear transmission analysis is established.

Abstract:
Induction hardening (IH) is a popular choice for automotive components such as camshafts for its ability to harden portions of a component selectively. The camshaft will contact the tappet, connected to the rocker arm, to open and close the valve whenever the engine is running. This contact between the camshaft and the tappet causes wear on the camshaft surface. IH of the camshaft is required to improve wear resistance and service life, as well as core elasticity to absorb high torsional stresses. It is known that studies about IH on camshafts are still very limited. This study aims to determi

Camshafts are crucial components in combustion engines. Their purpose is to control the opening and closing of intake and exhaust valves, which affects various aspects of an engine’s performance. The valves control the intake of the air-fuel mixture in the combustion chamber and the exhaust of combustion gases. The synchronization of this task with the engine’s cycle is essential for the system to work as desired, and timing parameters such as valve duration affect the engine’s power and efficiency.

Results show cracking to occur mainly in the opening ramp of the most abusively ground cam lobes.
