The main reasons for feeling a lack of power when pressing the car accelerator are related to the car's valves, fuel injectors, and pedal sensors. The specific situations are as follows: 1. Valve failure or intake pipe blockage: If the throttle valve fails or the intake pipe is blocked, it will result in insufficient air intake. Throttle valve failure affects the opening and closing degree, while carbon buildup in the intake pipe directly impacts the air intake volume. Reduced air intake affects the combustion efficiency of gasoline, leading to delayed acceleration. 2. Carbon buildup in fuel injectors or fuel line blockage: Carbon buildup in fuel injectors or fuel line blockage affects the fuel intake volume of the cylinders. Carbon buildup in fuel injectors affects the fuel spray volume, while fuel line blockage directly impacts the fuel intake volume or causes insufficient fuel supply. Insufficient fuel intake leads to an imbalance in the air-fuel ratio in the combustion chamber, resulting in incomplete combustion. 3. Pedal sensor failure: If the pedal sensor fails, the signal transmission when pressing the accelerator will be abnormal. This is also one of the reasons why there is a delayed response after pressing the accelerator.

Can You Buy a Mortgaged Car Without the Green Book?

It is not recommended to purchase a mortgaged vehicle, as many mortgaged vehicles may eventually lead to disputes. Although the price may be relatively cheap, you cannot have any traffic violations while driving the car, because handling violations requires the original owner to deal with them, which can be quite troublesome. Below are specific details about mortgaged vehicles: 1. Illegal Mortgaged Vehicles: When a motor vehicle is used as collateral, it is called a mortgaged vehicle. An illegal mortgaged vehicle refers to a car that is still under mortgage status with the vehicle management office and the bank, and the owner privately sells such a vehicle, making the purchase illegal. 2. Purchase Conditions: You should check the mortgage registration details in the "Motor Vehicle Registration Certificate." If the mortgage registration has been canceled, it means the vehicle's debt has been settled, and it is no longer a mortgaged vehicle, so it can be purchased. If the mortgage registration has not been canceled, the vehicle management office will not process the transfer procedures.

What does EGR mean in cars?

egr valve, namely the exhaust gas recirculation valve, is a mechatronic product installed on gasoline engines to control the amount of exhaust gas recirculated back to the intake system. EGR in cars stands for Exhaust Gas Recirculation system, which refers to redirecting a portion of the engine's exhaust gases back to the intake manifold, where they mix with fresh air-fuel mixture before re-entering the cylinders. The function of the EGR valve is to reduce nitrogen oxide emissions in the exhaust. Symptoms of a faulty EGR valve include: 1. Difficulty starting the engine and poor acceleration; 2. Failing emission tests; 3. Black smoke from the exhaust pipe; 4. Unstable idle or stalling at idle; 5. Check engine light flashing; 6. Engine oil burning; 7. Increased fuel consumption. Causes of EGR valve failure: 1. Quality issues with the exhaust gas recirculation system itself; 2. Improper maintenance; 3. Poor fuel quality; 4. Aging of the valve.
