Different Types Of Cars

1) Sports Cars- Sports cars are the perfect example of best automobile engineering, sports cars are usually two-seater small cars that are designed for quick response to move fast for spirited performance and nimble handling. They are brutal acceleration (0-100kmph in 2.3 sec Bugatti Chiron) and can achieve very high speed (436kmph hennessey venom GT). Some example of sports cars are Nissan GTR, Lamborghini Veneno, and Maserati Alfieri, Koenigsegg Agera etc. 2) Muscle Cars-A type of car designed for power and high performance, these cars have powerful engine, mostly V-8 and above with 2-door. Apart from this their performance, their look is muscular and aggressive. They are good for street driving and occasional drag race. Some common...

Multiple Injections In Modern Diesel Engine

Modern diesel engine feels very smooth, responsive and less noisy. They have very less emission and more efficiency. The fact behind all these improvements in diesel engine is diesel multiple injection. Multiple injection employs more than one injection in a single engine cycle (upto 5 injection in a single cycle). The 5 injection which occur in single engine cycle are:- Pilot injection Pre-injection Main injection After injection Post injection Pilot injection and Pre-injection- The small amount of fuel injected one or more times before the bulk fuel injection (main injection) is known as pre-injections. Injection far before the main injection is called pilot injection and the injection that occur just before the...

Variable Turbine Geometry (VTG) OR Variable Nozzle Turbine (VNT)

The simple turbocharger though increasing the power output of IC engine, also has some disadvantages at low and high RPM of engine. Turbo-lag (producing no turbo boost at low engine RPM) and Engine choke ( Due to high RPM of compressor, highly compressed air enters cylinders which is difficult to be compressed more in compression stroke). The waste gate technology was used to avoid the engine choke at high RPM by bypassing the exhaust gases directly to catalytic converter thus removing one disadvantage. The VTG is a technology that removes both the disadvantages of a turbocharger to some extent. The VTG has a movable guide vanes, which can change the angle and speed of exhaust gases striking on the turbine. LOW RPM At low RPM...

Variable Valve Timing In SI Engine

The goal is to increase the air entering the cylinder and thus burning more gasoline. The requirement of varying the different parameters is to allow more fuel to burn at high rpm, to give the good torque at high rpm and also to let more fuel to enter the cylinder during cold start. Name of this technology by different automobile companies VTVT (Hyundai) VVT-i (Toyota) i-VTEC (Honda) VCT (Ford) VVL (Nissan) Vario Cam (Porsche) Valuelift (Audi) Working of VTVT    Click Here ...

How Brake Booster works?

The brake booster is the device that decreases the brake pedal effort by the assist of vacuum, renaming the common brake as Power brake. The power brake works on the principle of pressure difference in brake booster. The brake booster has two chambers vacuum chamber and pressure chamber. Initially when brake pedal is free the power booster is completely vacuum on both sides of diaphragm (both chambers) and there is no entry of atmospheric air into any chamber of brake booster. The vacuum is created by connection of brake booster with the intake manifold of the engine, the suction of air by the engine pistons. When the brake pedal is pressed the vacuum chamber is sealed up and the atmospheric air is pressurized into the...

Automated Manual Transmission ~ AMT

It’s not automatic transmission that uses the hydraulic torque converter and gears on a single shaft but it’s the manual transmission that using various hydraulic actuators to engage and disengage the clutch and shift the gears. The sensors are mounted into the transmission box that sends the feedback and input to the Transmission Control Unit (TCU). The TCU has replaces the hands and the brains of the driver. First time AMT was seen on road in Ferrari 355 F1 in 1997.AMT is available in Maruti Celerio, Alto k10, Tata Zest, Tata Nano Genx in india It has three modes for driver Neutral Mode, Reverse Mode and Drive Mode Advantages  Same fuel efficiency as that of manual transmission Not much costlier than manual transmission...
