BS6 - Bharat stage 6 Emission norms

On 1st of April, the government of India upgraded the BS4 emission norms. These emission norms were a big step forward from the previous BS3 emission norms.
.
Though BS4 a huge step, it was a new emission norm after nearly a decade. The government thought of compensating the time hence decided to launch BS6 after BS4.
.
A Bharat Stage 6 ready engine has major modifications to its components to make it cleaner and adhere to the BS6 emission norm. Modifications like improved fuel quality composition and a DPF (Diesel Particulate Filter) and SCR (Selective Catalytic Reduction) in diesel cars are integrated with the exhaust system to make the vehicle BS6 ready.
.
BS6 emission norms which are stricter by reducing NOx emissions by approximately 25-70%. Additionally, under BS6 emission standards, the hydrocarbon emissions, and particulate matter emitted from tailpipes of vehicles would be controlled and reduced. India currently follows BS4 standards and it will the first country to transitioning to an emission norm by skipping an emission level, which would be BS5, entirely.

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
