World's Powerfull 4cylinder Internal combustion engine.

Which is the worlds powerfull 4 cylinder engine??

Here comes the mercedes M139 lets see the architecture and technical background behind it....

This is the turbocharged((twin scroll "[exhaust from cylinder 2,3 is one scroll and 1,4 cylinder is another scroll which prevents the exhaust pulse affexting the other cylinder]" turbo)for the first time mercedes uses roller bearing turbocharger which reduces friction and spools up quickly)2l inline four cylinder(transversely mounted)engine which produces 416hp(6750 rpm) and 369 lb-ft of torque(5000 to 5250rpm) which is used in the A45, the CLA45, the GLA45, and the GLB45. The design architecture is done with flattened front which increases the aerodynamics of the vehicle, cooler side of the engine facing front(intake and intercooler).

Configurations

Firing order-- 1,3,4,2

Cubic centimetre  -- 1991

Capacity    -- 2L

Power -- 416hp

Turbocharger -- twin scroll roller bearing tech with 30.5 psi of boost

Cyl block highlights -- closed deck which increases rigidity which peaks the internal compression pressure to 2320 psi

Fuel injection -- port + direct injection


Highlighted features
Twin wire arc sprayed cylinder liner which reduces friction and wear(mercedes claims that this reduces friction of piston rings and piston up to 50%)

Electric coolent pump to cool the engine.

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
