DECELERATION FEELING

From the point of view of driving characteristics, the time and smoothness of deceleration are considered when braking the engine and can vary significantly between different cars under the same external conditions.They depend on the following design features of the car:

• the type of transmission and gear ratios of the transmission – a mechanical one usually gives a more noticeable deceleration by the engine than an automatic one
• engine type – gasoline turbo engines have delays, engines with a higher torque give a more intense deceleration
• calibrations of engine control systems – due to the correct calibrations, suitable deceleration speed and smoothness are achieved
• car weights – heavy cars slow down more smoothly and more slowly, light cars slow down faster but less smoothly.

When the engine is braking, the deceleration occurs gradually – the engine begins to resist after releasing the PA when the gear is engaged.Engine braking is always smoother compared to sudden braking by the service braking system.

The deceleration process should proceed evenly, without sudden jerks – the traction force should decrease sequentially.

The wheels do not lock when the engine is braking, which reduces the likelihood of skidding even on slippery roads.
