Why Do F1 Engines Break So Easily

Formula One or F1 is a dangerous sport. The powerful turbocharged cars are driven at the speed of 200 mph (miles per hour) on the tracks, and the reported accidents of exploded cars with scattered debris from sudden crashes are an integral part of F1 sport. Here are three reasons ascertaining the breakdown of F1 cars in the racing lane.

The peer pressure of approximately 10600 times the force of gravity imposed during the racing and the resultant thermal reactions from tons of stress is considered the first reason for the sudden breakdowns. The complicated working of the six separate power units of the F1 cars has not well ascertained working experimentation research in every permutation and combination. At some point, their turbo-kinetic mechanism yields to uncalled ambushes or a shocking halt of the engine.

The Stress Quotient

The stress and pressure exerted on the machinery are incredible. A 2021 F1 car, running at 18,000 rpm (revolutions per minute), uses 360 litres of fuel/air mixture. 3 litres of coolant is pumped out with 1 litre of oil that runs through the engine. The 9.8mm (in max.) pistons are under stress of 1450 psi, developing about 350°C of heat on top and 200°C at the bottom surface. The tons of pressure creates a massive strain and exhaustion of the engineering. 

The Complicated Power Units

There are six separate systems of the F1 cars making up the engine. The first turbocharged system, along with two energy recovery systems, an energy storage system, and interconnecting machinery, forms the working unit called the engine or the power unit. Their complex working mechanism is not well assessed in all combinations. Their indefinite and doubtful working combinations bring the car to a daunting halt, as their mechanism is very complex to trace and sort.

The Fragile Tolerance

The pre-heated oil and warmth of 80°C are required to start the engine, as they are seized effectively when it is cold. The power components can last up to four or five rounds of 305 kilometres. Though the F1 cars are built with lightweight parts, their integrated working systems and combustion and thermal outputs yield fragile tolerance issues, leading to fragile tolerance.
