As altitude increases, the air becomes thinner and less dense. This means that there is less oxygen available for the engine to burn with the fuel. Without enough oxygen, the fuel cannot combust properly and the engine will stall.
Yes, changes in altitude can significantly affect a petrol engine's performance. As the altitude increases, the air pressure decreases and the air becomes thinner. This can lead to reduced power, increased fuel consumption, and potential stalling of the engine.
The air-fuel ratio is crucial for proper combustion in a petrol engine. At higher altitudes, the air is thinner and there is less oxygen available for combustion. This means that the air-fuel ratio needs to be adjusted to compensate for the reduced oxygen levels, otherwise the engine may not function properly.
Yes, there is a difference in how petrol and diesel engines perform at high altitudes. Diesel engines have a higher compression ratio, which allows them to compress the thinner air at higher altitudes and maintain their performance. Petrol engines, on the other hand, may struggle with the reduced oxygen levels and may experience stalling or reduced power.
Yes, a petrol engine can be modified to perform better at high altitudes. One way to do this is by adjusting the air-fuel ratio to compensate for the thinner air and ensure proper combustion. Some engines may also benefit from modifications to the fuel injection system or the addition of a turbocharger to increase air intake and improve performance at high altitudes.
