The different types of engines used in automobiles include gasoline engines, diesel engines, electric motors, and hybrid powertrains.

The engine is the power source of an automobile and is responsible for converting fuel into mechanical energy to propel the vehicle.

The main components of an automobile include the engine, transmission, suspension, steering system, braking system, electrical system, and body structure.

The different types of automobiles include cars, motorcycles, trucks, buses, and off-road vehicles.

Tyres colour is black due to the proportion of carbon mixed in it during the vulcanization of the rubber, to make the tyre shear resistant. Without vulcanization tyres won’t be able to bear the friction heat and stress of the road. Thus carbon is responsible for giving tyres the prominent black colour. Adding of carbon…

In case of cars the torque is applied to the rear wheels, thus limiting accelerator due to front wheel drive due to weight transfer. This drive is bolted to the chassis of the car. Modern manufacturers therefore design rear wheel drive to have similar handling to front wheel drive wherever possible via suspension tuning.

The basic difference of BS2 and BS3 engines is the presence of catalytic convertor. Catalytic convertor is present in BS3 engine which helps in reducing the formation of HC and CO. While in BS2 engine, no catalytic convertor is present which forms HC and CO. Thus in BS3 engine there is no emission of harmful…

The kingpin offset is the part, basically called as pivot used in the steering of the vehicles. This offset helps in rotating of the steering and thus it’s very useful in steering mechanism of the cars.Applications: This is also used to measure scrub radius with the help of geometric parameters of wheel plane above and…

Large tyres provide larger surface area touching the ground, thus providing the more pulling power. Basically tractors have larger rear tyres because tractors don’t have to operate at higher speeds, thus getting the same ground speed with larger tyres. Moreover gear ratios don’t have to be as high as b/c of the tyres.

Automotive engineers, also referred to as “automobile engineers”, work with other engineers to enhance the technical performance, aesthetics and software of vehicles. Common responsibilities of an automotive engineer include designing and testing various components of vehicles, including fuel technologies and safety systems. They may also come up with and design new vehicle models or vehicle…
