ABS brake system working in tamil

An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses.[1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface. ABS is an automated system that uses the principles of threshold braking and cadence braking, techniques which were once practised by skillful drivers before ABSes were widespread. ABS operates at a much faster rate and more effectively than most drivers could manage. Although ABS generally offers improved vehicle control and decreases stopping distances on dry and some slippery surfaces, on loose gravel or snow-covered surfaces ABS may significantly increase braking distance, while still improving steering control.[2][3][4] Since ABS was introduced in production vehicles, such systems have become increasingly sophisticated and effective. Modern versions may not only prevent wheel lock under braking, but may also alter the front-to-rear brake bias. This latter function, depending on its specific capabilities and implementation, is known variously as electronic brakeforce distribution, traction control system, emergency brake assist, or electronic stability control (ESC) Module (ECM)? What is the ECM, and how does it work? The Engine Control Module (ECM), also called the Engine Control Unit (ECU), ensures that your vehicle operates at optimal performance. The ECM monitors the sensors in the engine bay of your vehicle by managing your vehicle’s fuel mixture and regulating the emission control system. The ECM regulates four main parts of your vehicle’s fuel injection system: air-fuel ratio, idle speed, variable valve timing, and electronic valve control. In terms of the air-fuel ratio, the ECM uses sensors to regulate the oxygen to fuel level detected in your car to detect an engine rich/lean reading. For the idle speed, the ECM relies on sensors located in the crankshaft that track your vehicle’s RPM and engine load while the vehicle is idle. The variable valve timing is in relation to the flow of air into your vehicles cylinder to increase either power or fuel economy. Lastly, the ECM controls the hydraulic pumps which determine the rate of fuel injection that maximize the valve rate of opening per intake stroke to improve engine performance. #YouTubeengineering
