Car shaking while driving can be caused by: 1. Aging engine mounts; 2. Unstable oil pressure, abnormal fuel pump supply pressure, or incorrect readings/malfunctioning intake pressure sensor; 3. Severe engine carbon buildup, where gasoline injected by cold start injectors gets largely absorbed by carbon deposits, resulting in excessively lean air-fuel mixture during cold starts; 4. Ignition system issues, including malfunctioning ignition system or spark plugs; 5. Significant tire pressure differences causing uneven force distribution while driving. Solutions for car shaking include: 1. Check oil pressure and replace faulty components; 2. Inspect or replace spark plugs; 3. Replace brake discs promptly; 4. Clean fuel system, check idle control valve for carbon buildup, promptly clean and inspect oil pressure, replace problematic parts; 5. Inspect engine to identify faulty components; 6. Clean fuel filter.

What are the reasons for the ABS light to come on?

ABS light comes on because: There is a fault in the ABS system, manifested as deterioration in the vehicle's braking performance, increased braking distance, and reduced handling performance during braking. Therefore, when the ABS light comes on, the fault should be promptly addressed. ABS is the Anti-lock Braking System, developed by Robert Bosch GmbH for use in motorcycles and cars. When a vehicle encounters an emergency situation and emergency braking is applied, ABS can prevent loss of control and increase the braking distance to enhance vehicle safety. Generally, the ABS in family cars is always on and in standby mode, meaning it cannot be manually deactivated or turned off.

What is the normal RPM when starting a car?

When starting a car, an RPM of 1200 to 1500 is normal. In cold seasons, the engine RPM may be even higher because the vehicle may stall if the RPM is too low. A slightly higher RPM helps warm up the engine faster. However, during a cold start, the RPM should not be excessively high because the lubricating oil cannot reach the upper parts of the engine. To minimize wear, keeping the RPM below 2000 is ideal. Once the engine stabilizes, the RPM will drop to around 800. An engine is a machine that converts other forms of energy into mechanical energy. It originated in the UK and can refer to both the power-generating device and the entire machine, including the power unit.

What are the correct steps for parking a car?

Correct steps for parking a car are: 1. Manual transmission: First press the brake, when the speed decreases to near stop, then press the clutch, then press the brake firmly to stop the vehicle; 2. Automatic transmission: Put into N gear and pull the handbrake, release the brake pedal (letting the handbrake take the load), then press the brake pedal again, shift to P gear, and then turn off the engine. Manual transmission is also known as MT, which means manually moving the gear lever to change the gear meshing device inside the transmission, altering the gear ratio to achieve speed change. Automatic transmission usually refers to the car's automatic gear-shifting mechanism, where the control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load while driving.

Where is the cabin air filter located in an Iveco vehicle?

Iveco vehicles have their cabin air filter positioned inside a black box above the engine compartment. While driving, the vehicle draws in external air into the cabin, which often contains numerous impurities. The cabin air filter serves to purify the air entering the vehicle interior. With prolonged use, the cabin air filter may become clogged and requires regular replacement. There are two types of cabin air filters: one without activated carbon and another with activated carbon, with the latter offering better filtration performance. The dimensions of the Iveco low-roof short-wheelbase model are: length 5151mm, width 2011mm, height 2307mm, with a wheelbase of 3000mm.

What is the working principle of an expansion valve?

The working principle of an expansion valve is to automatically adjust the refrigerant flow rate based on the temperature of the refrigerant at the outlet of the evaporator. This type of thermal expansion valve is rarely used in fluorine-based systems. Thermal expansion valves are categorized into internal balanced and external balanced types according to their balancing methods. The external balanced thermal expansion valve comes in two structural types: F-type and H-type. The expansion valve is a relatively common component widely used in refrigeration systems. It enables medium-temperature, high-pressure liquid refrigerant to be throttled into low-temperature, low-pressure wet steam, thereby controlling the valve flow rate. It is often installed at the refrigerant inlet of the evaporator.

How to Tell if Engine Oil is Synthetic or Semi-Synthetic?

To determine whether engine oil is synthetic or semi-synthetic, check the bottle label: Full synthetic oil will be clearly labeled as "full synthetic" on the bottle, while semi-synthetic oil will be marked as "synthetic type" or "synthetic technology." Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. The main functions of engine oil are to reduce friction and wear on moving parts, remove sludge and varnish from the engine, neutralize acids produced by fuel and lubricant oxidation, improve piston ring sealing, and cool the engine by carrying away heat from moving components.
