Will stepping hard on the accelerator in N gear cause problems?

[DiCole]

Stepping hard on the accelerator in N gear can cause problems and certain damage to the vehicle. Aggressively pressing the accelerator will subject some components in the engine to significant inertial forces, thereby shortening the engine's lifespan. If the engine has just started, revving it hard in neutral can also accelerate engine wear. Relevant details are as follows: Impact on engine reliability and lifespan: When the car is in neutral, the engine has no power output. At this time, stepping hard on the accelerator causes the engine speed to rise sharply, and the rapid acceleration of moving parts such as pistons and connecting rods generates substantial acceleration forces, subjecting them to significant alternating loads. The stress on the piston, piston pin, connecting rod, connecting rod bolts, and crankshaft may exceed that during normal operation. Hazards of stepping hard on the accelerator: When the accelerator is pressed aggressively, the speed increases sharply, and the lubrication of each friction pair cannot keep up, easily leading to faults such as cylinder scoring or valve damage. Therefore, neutral acceleration should be avoided. If the accelerator is pressed hard when the engine is cold, the damage to the car's engine will be even greater and non-negotiable, as the oil film covering the internal parts may not be fully formed. Aggressively pressing the accelerator can cause excessive wear on the engine's metal mechanical components. If the cooling system is not circulating properly, it can easily lead to engine overheating. Excessive wear of piston rings and cylinders can weaken airtightness, posing risks such as oil burning or even dry friction, potentially leading to cylinder explosion.
