Book Description:

Automotive Mechanics book PDF Engine Testing Theory and Practice book by A.J. Martyr, M.A. Plant brings the through information about Engine testing processes and methods and how to implement them. It includes the contents of vehicle mechanics also. This exclusive book is a genuine must-have reference for automotive engineering and car business, in addition, to understand the process and background of vehicle manufacturing.

The auto mechanics is the branch of mechanics that studies and applies the proper principles of physics and mechanics for the generation and transmission of movement in automotive systems, such as motor vehicles.

The mechanical term refers mainly to call all professionals who are involved in the construction of industrial equipment and machinery, as well as its assembly and maintenance when the machines years of learning both theoretical and practical. This training is explained in the Vocational Training Institutes. This Automotive Mechanics Book PDF Engine Testing contains this information also. In their professional tasks, the mechanics handle a good amount of tools and measuring instruments. Automobile Suspension system plays a vital role in mechanics of a vehicle enabling it to absorb shocks and vibrations.

Automotive mechanics involves:


It is the element responsible for the generation of movement.

Timing belt

The timing belt also referred as Cam belt in some Automotive mechanics books, or toothed belt, is one of the most common methods of transmitting mechanical energy between a trailing pinion and a driven pinion, by means of a mutual toothing system that has both the belt and the pinions, preventing their mutual sliding. It is very often used in Otto and 4-stroke diesel engines testing between the crankshaft and the camshaft, in motorcycle engines and industrial machinery, it is a rubber belt that normally links a motion generator to a receiver thereof by means of pulleys or pinions.


A camshaft is a mechanism constituted by an axis in which different cams are placed, which can have different shapes and sizes and be oriented in different ways, to activate different mechanisms at repetitive intervals, such as for example valves, say, constitutes a cyclic mechanical timer.

Motion transmission


The clutch is a system that allows both transmitting and interrupting the transmission of a mechanical energy to its final action voluntarily. In a car, for example, it allows the driver to control the transmission of torque from the engine to the wheels during testing.


The gearbox or gearbox (also called simply box) is the element responsible for obtaining enough torque on the wheels to start the vehicle from a standstill, and once it is underway, obtain enough torque to overcome it. the resistance to the advance, fundamentally the aerodynamic resistances, of rolling and slope. In Automotive Mechanics Book PDF, different types o the gearbox are discussed with clear process diagrams.

Transmission shaft

The transmission shaft or transmission system in automobiles is the element responsible for transmitting the movement of the engine to the wheels. Most of the Engine testing is done with transmission shaft.

Conical-differential group

It is the element of the transmission that distributes the power of the movement to the wheels, stabilizing the speed of the wheels depending on the curves.
