What is the reason for the bending or breaking of Bare Engine?

2025-07-03

Water ingress into Bare Engine causes the connecting rod of Bare Engine to bend or break. When the vehicle is driving on a road with water on the road, the MG Roewe Maxus Engine will suck water into the cylinder.

The water that initially enters the cylinder quickly forms hydrated gas under the action of the high temperature of the cylinder body, making it impossible for the cylinder to form a combustible mixed gas.

As the amount of water inflow increases, water will accumulate on the top of the piston, reducing the effective volume of the combustion chamber, increasing the compression resistance, and increasing the pressure transmitted to the connecting rod by the piston.

When the water accumulation reaches a certain level, the compression stroke actually becomes a compression of water, and the pressure on the connecting rod increases sharply, and even bends and deforms until it breaks, or even breaks the cylinder body of the MG Roewe maxus engine.

Not all vehicle Bare Engine will have their connecting rods break immediately after water ingress, because the amount of water inflow into the cylinder body of the MG Roewe Maxus Engine and the speed of the MG Roewe Maxus Engine determine the pressure on the connecting rod.
