| Advantages of vehicle engine braking.
The first important advantage of engine braking is that its use significantly increases the life of parts of the main braking system. The average brake pad life of different Rme vehicles and its limits of reliability are given in Table 1. Table 1 – Average brake pad life R me of various vehicles and its boundaries Vehicle’s type R me thousands km Boundaries, R me thousands km Low High GAZ-3221 13.8 13.1 14.5 VAZ-2110,2115 24.5 13.7 35.3 KAMAZ-5320 76.0 54.0 98.0 IKARUS-280 54.5 34.8 74.2 Mercedes Benz 0 302 S 33.8 19.6 48.0 MAZ-64229 64.2 36.5 91.9 It is clear from the table, the average service life of brake pads of passenger vehicles is rather small – 13... 24 thousand km, therefore regular use of engine braking during braking, can give significant economic effect. The second advantage of internal combustion engine braking is that it uses less wear on the tire tread, as they are smoothly loaded with the braking torque. The third advantage of frequent use of combustion engine braking in service braking on modern automobiles is a significant fuel saving by stopping its consumption in this mode (fuel pump stopped). 34 The fourth advantage of ICE braking is that it can be used on vehicles with any drive: front, rear, full wheel drive. The fifth very important advantage of ICE braking is that its frequent use can improve many important performance features of the vehicle: 1. Increase the controllability and stability of the vehicle, especially when braking on slippery road surface, as well as in case of loss of stability due to exceeding the critical speed of the vehicle with excessive turning; 2. Increase the reliability of the vehicle's braking system by reducing the wear of brake pads, drums, disks and preventing brake failure in the case of overheating on tight and steep slopes, as well as due to the fact that it allows you to stop the vehicle in case it is not possible to brake it the usual way. 3. improve the fuel efficiency of the vehicle by stopping its consumption in the ICE braking mode. жүктеу/скачать 6,6 Mb.
