engine knock

engine knock with the help of a sketch.

• engine knock occurs when a self-ignition of a part of the mix before reaching the flame front occurs.

Why is a high boiling point of the brake fluid required?

• With more time and braking, the brake fluid heats up.
• in that case, the brake fluid boiling.

The United States Department of Transportation (DOT), Describes three classes of brake fluid (DOT 3, DOT 4, DOT 5)

boiling point table:

parameters	DOT 3	DOT 4	DOT 5
boiling temperature [° C]	≥ 205	≥ 230	≥ 260
nut boiling point [° C]	≥ 140	≥ 155	≥ 180
viscosity at 100 ° C [mm ² / s ]	≥ 1.5	≥ 1.5	≥ 1.5
cold viscosity at -40 ° C [mm ² / s ]	≤ 1500	≤ 1800	≤ 900
