Volkswagen's EA888 series engines


This TSI(Turbocharged stratified injection)is the heart of volkswagn GTI comes under the family of EA888.

Now what is EA888??? The EA888 is the four or three cylindered engines made by volkswagen groups.These GTI uses four cylinder EA888 engine with advanced technologies which are mentioned below and has number of sensors and mechatronics which increases the engines intelligence and good man machine interface.

⚡Specifications(It has more types only the 2.0 litre is discussed)

💥Engine : 2.0L turbocharged inline 4 cylindered.Engine block Made of iron and aluminium alloyed head. 

💥weight : 320 pounds (145.15kg) approx. 

💥Firing order : 1-3-4-2. 

💥Bore : 82.5mm .

💥stroke : 92.8mm .

💥Displacement : 1.984L(1984cc) .

💥Power : 220HP @ 4700RPM. 

💥Torque : 258lb-ft(347NM)@ 1500-4500 RPM.

. 💥Redline : 6800 RPM. 

💥Compression ratio : (9.6 : 1). 

💥Cam : Dual Over Head Cam (DOHC)*chain driven cams

💥Valves : 16 valves (VVT @ inlet) (VVL @ Exhaust).
.
. ⚡Technologies and highlights.

💥water cooled Exhaust : The exhaust manifold is integrated with cylinder head so the coolant is heated up very qucikly with increases the thermal effeciency, reduces the wear,enhances the catalytic convertor's work. 

💥variable valve lift : It has four sliders on the exhaust cams.The cam slides during operation which has more lift on the cam.The higher lift increases the exhaust flow during higher RPM. 

💥Balance shaftes :mounted up higher in engine block.It eleminates the secondary forces made by engine and reduces the Noice and vibration of the engine. 

💥varying link intake manifolds : It optimizes the torque and horsepower throughout the RPM range. It has adjustable flaps which helps the engnie a lot above 3.8k RPM. 

💥Fuel injection system : Direct injection.The nozzle contains 6 tiny poers for the fuel to be sprayed directly into the cylinder.The fuel comes out roughly at 50 degree cone it prevents the fuel hitting the intake valves and avoids the valve damage.It can function over 200 bar.The fuel injection is controlled by the solenoid coils.

. 💥variable oil pressure,EGR system,cam controll by chain and sproket etc..,

Retarder braking system

Image
RETARDER BRAKING SYSTEM Breaking the truck generates high amount of pressure,wear and heat on the brake disks and brake pads and in some cases,continuous braking during downhill or in traffic leads to the decrease of brake pressure,The truck needs to halted in safe place to recharge the compressor. The best solutions for these safty less conflicts is the RETARDER BRAKING SYSTEM. The reatarder brake system gives the smooth braking experience with no energy loss,wear,noise while slowing down the heavy loaded trucks.It saves the maintainance cost on replacing the brake disks,linings and brake pads. HOW RETARDER WORKS? Retarder is a hydraulic system that is integrated into the output end of a truck’s gearbox and uses high-pressure oil as a braking medium Via a gear transmission, the Retarder acts on the output shaft of the gearbox and thus directly on the propeller shaft. Once the Retarder is applied, it generates a braking force on the propeller shaft corresponding to up to

IVTEC system

IVTEC SYSTEM . .  IVTEC stands for intelligent- variable valve timing and electronic lift control is a system developed by honda to increase the volumetric efficiency of an internal combustion engine, resulting in higher performance at lower RPM. Here the cam phasing is implemented by computer controlled, oil-driven adjustable cam sprocket or the electrically actuated cam phaser (it replaces the oil pressure actuated cam phaser). Thus, this system provides continuous cam phasing and discrete variable valve lift controls using CPS concept. This system consists of a camshaft with a centre high lift cam and outer low lift cams and associated rocker arms. For light load operation, the valves are operated by the two outer, low lift cams and associated rocker arms. For high power operation, hydraulic pressure is used to insert a pin to lock the middle rocker arm to the outer rocker arms for operation on the high lift cam. Cam phasing is accomplished with a hydraulic cam phaser.

Gate exam 2022 subjects for mechanical Engineering.

Image
WHAT IS GATE?                                                  The GATE is abbreviated as Graduate Aptitude Test in Engineering which is a national-wide exam of India, conducted by 7 IIT'S and IISc Bangalore. This exam is completely a computer-based test that tests for the comprehensive understanding of various subjects in the undergraduate program. This score is mainly required for admission for master's program in various IIT's IISc's and several other government-funded top colleges in India with financial assistance.  GATE score is very much important for recruiting graduate engineers in public sector units.            Cracking this exam is very much easy for those who have a complete application and aptitude-based knowledge in engineering subjects. Proper planning and hard work can get you a better rank in this test.     SYLLABUS FOR MECHANICAL ENGINEERING(ME)  SUBJECTS FOR ME:  GENERAL APTITUDE: Verbal aptitude, Quantitative aptitude, Analytical aptitude, Spatial
