Technology Bible from Bosch

Bosch is a revered name in the Indian automobile Original Equipment Manufacturer’s scene. Many of the engine components as well as vital chassis parts are now been manufactured by Bosch India and hence taking a cue from their extensive parts bin, we have taken the time to put together a few pieces of their information from their tech bible and have incorporated them in this article.

Throttle Body:

This is located between the air box and inlet manifold. The function of the throttle body is to control the intake of air into the engine. The throttle valve, which is present inside it is started by the accelerator pedal position sensor or by a cable in the accelerator pedal.


It is a component of the valve train. It is basically a test tube, shaft or even a cylindrical projection which is a camshaft follower and converts the rotating motion of the camshaft into a reciprocating one required to close or open the valves of the cylinder.


It is the end section of the exhaust system in a car. Found in the rear section of cars, it is protruding pipe. Some of the exotic cars have multiple tail pipes. The function of it is to emit the exhaust gases from the car into the atmosphere.


It is found in the engine bay of a car and injects fuel inside the engine cylinder or in the inlet manifold. It is actually a nozzle and is made of high heat resistant substances.


The angle between the vertical and the car’s wheel is called Camber. If the top of the wheel is tilted inwards, the camber is considered negative whereas if it is tilted outwards, it is called as positive angle. To avail of better traction, the wheels have negative camber and this means that they are tilted inwards.


Sipes are the cuts or grooves found in the surface of rubber in car tyres. These function by the way of chanelling away dirt and water from the tyres in order to maintain traction on the road surface.

Longitudinal engine:

If the car’s crankshaft is placed perpendicular to the wheel axles, the car’s engine is said to be longitudinal engine. Such engines usually have higher power output and torque compared to others.


It is a phenomenon which happens when a car loses traction in slippery or wet conditions. The car may even slide out of control due to its inability to dispel water from underneath the tyres and the road. It is said that cars with wider tyres have more chances of aquaplaning.
