Mechanical Engineering

Mechanical engineering is the discipline that applies the principles of engineering, physics, and materials Science for the design, analysis, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the design, production, and operation of machinery. It is one of the oldest and broadest of the engineering disciplines. Mechanical engineers are employed in operations and maintenance roles in manufacturing and services industry. It is an evergreen branch with no cyclic trend in the job market. Some of the largest areas of employment of Mechanical diploma engineers are in productions, machine tools, railway engineering, aerospace, the automobile industry, power plants, armed forces and paramilitary forces.
Automobile engineering is a branch of vehicle engineering, incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the design, manufacture, and operation of motorcycles, automobiles, trucks, etc. and their respective engineering subsystems. Automobile engineers are employed by automobile design and manufacturing units, automobile ancillary industry and automobile service sectors.
Automobile engineering is a branch of mechanical engineering, where you'll deal mostly with the automobile, whereas in mechanical engineering, you'll deal with all machines and its design and then many more basics. But literally, both are same, no big difference. Syllabus of automobile engineering overlaps with mechanical engineering between 80 to 90%. Compulsory courses on the engineering drawing, workshop, instrumentation, thermodynamics, strength of material, the theory of machines, heat transfer, refrigeration, etc. are common in both mechanical and automobile engineering but additional like automotive chassis, engine, dynamics, body engineering suspension, transmission, automotive electronics & electrical are perpetrate.
Automobile engineering is a niche branch thus it is having low opportunities in comparison to mechanical engineering graduates. Mechanical engineers are employed in automobile industry but automobile engineers may not be preferred in the core mechanical jobs.
