  Vehicle Chassis Frame and Body The function of the chassis frame is to take the full load of the vehicle. It is a skeleton of the motor vehicle especially in heavy-duty and some light-duty cars, it must be strong enough and light in design.  The chassis frame of an automobile of following components suitable mounted and bolted: • Engine and radiator  • Transmission system, consisting of the clutch gearbox, propeller shaft, driveline and front and rear axles. • Suspension system and its related parts. • Steering system, braking system and under chassis components and parts.  • Vehicle Body, fuel Tank and battery mounting unit. In the construction of an automobile chassis frame C - section Channel chassis frame, Box type section channel, Hat section chassis frame and I - section channel chassis frame used on the heavy trucks buses and mid-light duty vehicle. Normally the various components are bolted directly to the frame  Frame   The frame is that part of ...

I  The vehicle uses for transportation from one place to another place upon the ground or road like cars, trucks & buses and on the air like a plane and in water on the ship, all these things powered by Engine fuel which made by petroleum. (Petrol & Diesel fuel). In the context of Automobiles/Automotive engines, We find Internal Combustion engines (ICE), Four-stroke cycle Engine in your vehicle. Automobile Engine   An engine is a machine that converts heat energy into mechanical energy. The heat from combustion (burning ) a fuel produces power which moves the vehicle on the road. Some time engine is also called a power plant.  Automobile engines are Internal Combustion Engine (ICE) because the fuel run them is burned internally or inside the engine. It is powered by either a Petrol engine or Diesel engine. Both engines run with a four-stroke cycle operation. May rotary engine means a rotor that spin or rotates, an engine called a Wankel design in which a three-lob...

 Flex Fuel  \ Flexible Fuel Vehicle (FFV), Duel Fuel, Flex Engine & Biofuel. The flex-fuel vehicle is as same as conventional Spark Ignition Engine Vehicles based on an internal combustion engine. Flex-fuel vehicles or dual-fuel vehicles have an engine capable of operating the functioning of dual-fuel ethanol and gasoline (petrol) with the formed mixture called blended fuel. All fuels contain ethanol to some percentage, it depends on containing ethanol and gasoline (petrol) in the blended fuels according to government policy. It mixes ethanol with other relevant fuels to make them energy productive. This flex-fuel technology is not new it was first developed in the early 1990s and used in mass production in 1994, Ford Taurus according to data of car bibles by 2017. Now there were more than a 21million flex-fuel vehicles on the road in America. Around the globe ethanol flex-fuel vehicle, approximately 60 million automobile light and heavy-duty vehicles run in the world. by ...

  Automobile Braking System An automobile braking system is a mechanical device that works at hydraulic pressure using brake fluid under pressure to the brake network in each wheel in light-duty vehicles. In modern vehicles power assist braking systems for the sake of safety and convenience also less force effort for the driver. There are several power resources used for more effective braking these are main sources engine vacuum, air, engine exhaust gases, regenerative braking and electric braking. In heavy-duty vehicles, air braking is most commonly used in trucks and buses, along with an Antilock braking system (ABS) in both heavy-duty and light-duty vehicles. Purpose and function of Braking system: Automobile brake action may be defined as the which stop any motion. Brakes are applied to slow down or stop the moving car or any vehicle. The function of the brake is to reduce the speed to stop moving vehicles within a minimum possible time and a minimum possible distance and hold...

AUTOMOBILE STEERING SYSTEM & STEERING GEARS In modern automobiles or automotive steering systems one of the major control systems for under chassis components of the vehicle. " A device for controlling the directional change of vehicles travel". The Purpose of the Steering System: The steering system allows the driver to control the direction of vehicles travel. This system consisting ( made up) steering linkage that connects the steering wheel to the steerable wheels and tyres. The system may be either manual or power steering. The main energy source for the steering system, to the driver, applies to force or steer the steering wheel, quite more force to applies to steer on the manual steering system and less force/ effort applies to steer the power steering system. The steering system gets movement from the steering wheel, steering gears, steering linkage, wheels and tyres. the power steering includes additional components like a hydraulic pump and their system or elect...

VEHICLES CALIBRATION ENGINE REMAPPING ENGINE TUNE-UP ENGINE OVERHAUL The purpose of Calibration is to help assure accurate and proper measurement and to optimise efficiency, driveability, performance durability and safety measures of the vehicles. We heard the word of calibration frequently in modern vehicles when we take our vehicle periodic maintenance in the authorised dealership. Modern vehicles calibration has become a vital role play in your car. Calibration is a set of operations that under certain conditions establish a relation between values indicated by measuring the accuracy operation of electronic components as well as mechanical parts and systems.  So that your vehicle is assured smoothly and with optimal performance. Celebration, Why do we need it? The same engine may be used in several different vehicles. These vehicles will have different characteristics, How can the same engine be distinctive? The Electronic control module / Unit controls the engine using differen...

 Power Boost Devices Of The Automobiles Engine Turbocharger and Supercharger Turbocharger and supercharger are both powers booster devices, which is act as air compressors used to increases oxygen flow into the engine through forced induction. The forcing additional air-fuel mixture or air in the engine cylinders means more air or allows more oxygen into the combustion chamber this combustion process creating a greater output of power so that an engine can produce more power at the same engine speed. As well as enhance the engine efficiency. This process is called the forces induction of the engines. By these forces, induction may produce 35 to 60% more power as compared to naturally aspirated petrol and diesel engines.  The forced induction may be provided by a supercharger or by a turbocharger. These are types of air pumps or blowers that force more air-fuel mixture or air into the engine. Both are working as similarly but differently operates in the automobile engines. The ...
