Why Does the Car Feel Bumpy on a Smooth Road?

The reason why the car feels bumpy on a smooth road is due to faults in the vehicle's chassis system components. When the hydraulic shock absorbers fail, the repeated extension and compression of the springs cannot be effectively suppressed, causing the car body to bounce up and down, resulting in a bumpy sensation. There are three main scenarios where the car feels bumpy on a smooth road: 1. Suspension system failure causing bumpiness during smooth road driving; 2. Tire imbalance leading to bumpiness during smooth road driving; 3. Improper wheel alignment resulting in bumpiness during smooth road driving. The solution to address bumpiness on a smooth road is as follows: First, drive at a low speed and then perform a sudden brake. If the car shakes severely and the occupants feel uncomfortable, it indicates a problem with the shock absorbers, and they should be replaced.

Why does the car shake violently after being parked for a month?

There are several reasons why a car may shake violently when started after being parked for a month: 1. Poor fuel quality: Low-quality fuel often has poor volatility, especially in winter when temperatures are low. During a cold start, the engine block temperature is low, making it difficult for the fuel to atomize. This results in insufficient mixing of fuel and air in the cylinders, causing starting difficulties and severe body shaking. 2. Carbon deposits in the engine valves and intake manifold: Carbon deposits can absorb a certain amount of fuel, leading to incorrect judgments by the electronic control unit. The actual fuel-air mixture controlled by the computer does not match the required parameters, and even if the mixture burns completely, it fails to provide the necessary power, resulting in shaking.

What is the actual fuel consumption of the Benelli Silver Blade 250?

The fuel consumption of this motorcycle is 3.2 liters per 100 kilometers. The fuel consumption of a motorcycle is not only related to the motorcycle itself but also to the driver's driving habits and road conditions. If the driving habits are poor and the motorcycle is frequently driven on roads with severe traffic congestion, the fuel consumption will be relatively higher. When a motorcycle starts from a stationary state, it requires a very high acceleration, and the engine needs to output a significant amount of power at this time. Therefore, frequent stop-and-go driving will inevitably increase the motorcycle's fuel consumption. If you want to improve the fuel efficiency of your motorcycle, the first step is to change your driving habits. When riding a motorcycle, try to avoid sudden acceleration and deceleration as much as possible, and aim to maintain a steady speed while driving.
