What is a car link -1.3T
The "1.3T" in the car 1.3T refers to the engine's displacement of 1.3L, where the "T" stands for turbocharging technology . Turbocharging technology increases the power and torque of the engine by increasing the intake of air, giving the 1.3T engine a power advantage, as well as lower fuel consumption and faster power output .
Specifically, the turbocharger uses the exhaust gas generated by the operation of the internal combustion engine to drive the air compressor, thereby increasing the intake volume and increasing the power and torque of the engine. The 1.3T engine is roughly equivalent to the 1.6-litre naturally aspirated engine in power, and can even reach the power level of the 1.8-litre naturally aspirated engine, but its fuel consumption is usually lower than the 1.8-litre engine .
Therefore, the car 1.3T is a technical solution to seek a balance between power and fuel economy, suitable for those who pursue a certain power and want to save fuel consumers .
The role of the connecting rod in the 1.3T engine mainly includes converting the linear reciprocating motion of the piston into the rotating motion of the crankshaft, and transferring the pressure borne by the piston to the crankshaft, so as to output power. In particular, the connecting rod is connected with the piston pin through its small head and the big head is connected with the connecting rod bearing of the crankshaft to achieve this conversion and transmission .
Working principle and structure of connecting rod
The connecting rod is mainly composed of three parts: connecting rod small head, rod body and connecting rod big head. The small end of the connecting rod is connected to the piston pin, the rod body is usually shaped in an I-shape to increase strength and stiffness, and the big end of the connecting rod is connected to the crankshaft by bearings. The connecting rod must not only withstand the pressure generated by the combustion chamber gas in the work, but also withstand the longitudinal and transverse inertial forces, so it is necessary to have high strength, fatigue resistance and toughness .
Damage form and maintenance method of connecting rod
The main forms of damage to connecting rods are fatigue fracture and excessive deformation, which usually occur in the high-stress areas on the connecting rods. In order to ensure the stability and reliability of the connecting rod, modern engines use high-strength materials and carry out precision machining and debugging. When the bearing performance of the connecting rod becomes poor or the clearance is too large, the new bearing should be replaced in time .
