4. FAQ
Q: What damage will thermal cycling and uneven temperature bring to pistons for BYD Han DM DM-i 1.5T engine? A: Repeated cold start, heating and cooling creates cyclic thermal stress on pistons. Long-term thermal alternating load triggers thermal fatigue and microcracks, which expand and cause piston fracture. Large temperature difference between piston crown and skirt leads to uneven thermal expansion and slight warping. Our barrel arc skirt profile pre-compensates such uneven deformation, ensuring uniform contact between skirt and cylinder wall under working temperature for BYD472ZQB engine.
