What causes the vibration of the Lynk & Co 03 three-cylinder engine in the later stage?

[JakeMarie]

The reasons for the vibration of the Lynk & Co 03 three-cylinder engine in the later stage are: 1. The spark plug is damaged, and the gap wear of the spark plug pole leads to insufficient spark plug ignition, resulting in incomplete combustion of the mixture; 2. Poor quality of gasoline leads to poor atomization effect of the fuel injector, and the mixture does not burn completely in the cylinder; 3. The throttle is too dirty, and the fuel injector has excessive carbon deposits; 4. The fuel pump supply pressure is abnormal, or the intake pressure sensor value is incorrect and the operation is poor. Taking the 2021 Lynk & Co 03 as an example, it belongs to a compact car with a body size of 4639mm in length, 1840mm in width, 1472mm in height, a wheelbase of 2730mm, and a curb weight of 1395kg. The 2021 Lynk & Co 03 has a MacPherson independent front suspension and a multi-link independent rear suspension. It is equipped with a 1.5T turbocharged engine with a maximum horsepower of 156PS, a maximum power of 115kW, a maximum torque of 245Nm, and is matched with a 6-speed manual transmission.
