Shock absorbers are usually fitted with the frame of the vehicle and the operating lever is connected with the axle by means of a link. As the axle goes up due to road bumps, the shock absorber is operated by the lever through the link. The shock absorber resists the effect due to road shocks and thus helps in absorbing the shock.

There are two types of wheels: * Group 'A' Solid Wheels * Group 'B' Pneumatic Wheels Solid Wheels This consists of a rim which contains sole of solid rubber. This is heavy in construction.

Two types of springs are used in the suspension system, i.e., * Group 'A' Leaf Springs * Group 'B' Coil Springs. Leaf Spring A Leaf Spring consists of a number of laminated leaves combined into one unit by means of a center bolt and rebound clips. The master or main leaf contains eyes at both ends, which provide connections for the spring to be fitted with the chassis frame by means of pins.

Live Axle Live axle contains the differential mechanism and the engine power flows through it towards the wheels. Dead Axle The dead axle is a dummy one and is the axle of not connected to the engines power. The dead axle, if it is the front axle, consists of the main beam of 'I' section, at both ends of which are fitted the stub axles by means of king-pins. The stub axles are free to moving the vehicle to different directions.

In order to have combustion in different types of engines, different types of equipment are required. For the petrol engine, Spark Plug, Magneto/Distributor, Carburetor or Fuel Injection Throttle-Bodies etc. are necessary accessories, whereas for a diesel engine, Injector and Fuel Injection Pump are e… Tue, 03 Mar 2009 14:21:48 +0700 http://www.rookieracing.info/dokuwiki/doku.php/engine?rev=1236064740&do=diff Power, which is required for the propulsion of an automobile, is developed by means of Power-Unit or Engine. Starting the engine develops the requisite power. In order to see how the power is developed, is to know how the engine is put into operation. If an engine is in the working order, the following checks have to be made for the development of power: Tue, 03 Mar 2009 14:19:00 +0700 http://www.rookieracing.info/dokuwiki/doku.php/start?rev=1236059541&do=diff An automobile is a self-propelled vehicle, which is used for the transportation of passengers and cargo upon the ground. Vehicle Vehicle is a machine, which is used for the transportation of passengers and cargo. Vehicle consists of two parts, i.e., carriage portion and machine portion.
