Why Your Truck Engine Shakes and How to Fix It

Anh Tuan, owner of a building materials store on Nguyen Trai Street, Thanh Xuan District, Hanoi, recently purchased a brand new Dongfeng truck to facilitate the transportation of goods. The truck is the family’s livelihood, cherished and cared for like a prized possession. However, his joy was short-lived when the truck suddenly started shaking every time he started the engine. Worried about a serious problem, Anh Tuan rushed the vehicle to a familiar garage on Le Van Luong Street for inspection.

Anh Tuan’s story is not uncommon. Engine shaking is a frequent issue, causing discomfort while driving and potentially leading to accidents. So, what are the causes and how can this problem be resolved? Let’s explore this in detail with XE TẢI HÀ NỘI.

Causes of Engine Shaking

Engine shaking when starting or running can be attributed to various reasons, ranging from simple to complex:

1. Faulty Spark Plugs or Ignition Coils

Spark plugs ignite the fuel in the engine. When they malfunction, the combustion process is incomplete, leading to shaking. Similarly, damaged ignition coils disrupt the electrical current to the spark plugs, causing the same issue.

2. Warped Cylinder Head or Damaged Head Gasket

The cylinder head connects the engine block to the cylinder head cover, and the head gasket seals the combustion chamber. A warped cylinder head or a damaged head gasket allows combustion gases to leak, resulting in engine shaking and even stalling.

3. Fuel Pump or Fuel Filter Problems

The fuel pump delivers fuel from the tank to the engine, while the fuel filter removes impurities. A weak fuel pump or a clogged fuel filter starves the engine of fuel, causing shaking and sluggish performance.

4. Clogged Fuel Injectors

Fuel injectors spray fuel into the combustion chamber. Clogged injectors prevent fuel from being evenly distributed to the cylinders, leading to engine shaking and uneven running.

5. Worn Engine Mounts

Engine mounts connect the engine to the vehicle frame, absorbing vibrations. Worn engine mounts amplify engine vibrations, especially during acceleration or deceleration.
