ඩීසල් දුමෙන් වාහනයේ වේගය අඩු කර ගැනීම | Exhaust Brake | Reducing vehicle speed using diesel exhaust

Hello friends, I work as an automobile instructor and. I have worked in Sri Lanka and the Middle East countries. I expect to teach you, how to maintain and repair a vehicle properly. If you want to learn more, visit the https://automobileteacher.wordpress.c... channel and web site is very important to the students, who are following technology subject. I expect your comments, to develop the channel. Thank you, for watching the video. Website - https://automobileteacher.wordpress.com/ Face book -   / devapriya2020   Twitter -   / dpakdevapriya   #engine #automobile_teacher #exhaustbrake Drivers need to know a little bit about its functionality and maintenance. I am ready to provide the necessary knowledge for free. I hope to offer more lessons in the future. I learned technology not just for a job but as a hobby. Industrial payments are saved and I get unlimited pleasure. I, as an automobile instructor, take pleasure in imparting knowledge to you. In addition, I have mastered auto electricity, home electricity, plumbing, web design, and internet marketing. So, how does an exhaust brake system work? Essentially, it works by trapping engine pressure in the exhaust system, which forces the engine to rotate slowly. Normally, pistons travel upward of the exhaust stroke in cylinder bore to force spent exhaust gasses out of the engine via the exhaust valve. When the exhaust brake is applied and the inline butterfly valve is partially closed, additional force is required to push the spent exhaust from the engine. The additional force slows the engine R.P.M. As the engine slows and the vehicle decelerates. In some exhaust brake systems, the vehicle E.C.U controls their operation. In others, the driver can manually actuate the exhaust brake. With either system, the mechanism that closes the butterfly valve may be powered by hydraulic pressure, air pressure or rely on an electronically operated servo motor. One main benefit is enhanced control and improved safety when navigating downhill slopes or carrying heavy loads. The system minimizes brake fade, heat buildup and wear on the brake liners and brake drums abd discs, extending their life and reducing maintenance costs. Additionally, the exhaust brake system aids in maintaining a consistent speed while descending steep grades, ensuring good stability of the vehicle. there are various types of exhaust brake systems designed to suit different vehicle configurations and engine types. The most common types include pneumatic, hydraulic and electronic exhaust brake systems. Pneumatic exhaust brakes function by restricting the exhaust flow through a butterfly valve in the exhaust pipe, creating back pressure to slow down the engine speed. Hydraulic exhaust brake system use a similar principle but use a hydraulic piston to restrict exhaust flow. Electronic exhaust brakes, on the other hand, use electronic controls to modulate the exhaust system, providing good braking force adjustments and integration with the vehicle's engine control unit (ECU).
