Petrol diesel combustion differences
Introduction Petrol diesel combustion differences | When you press the accelerator, the engine has to turn fuel into useful mechanical power within a fraction of a second. But petrol and diesel engines don’t accomplish this in the same way. The fuel may serve a similar purpose, but the combustion process, ignition method, compression ratio,…

Spark ignition vs compression ignition
Introduction Spark ignition vs compression ignition | When people compare petrol and diesel engines, they usually look at fuel economy, power, mileage, or maintenance costs. But the most important difference actually starts inside the engine cylinder: how the fuel is ignited. A petrol engine normally uses an electrical spark to start combustion, while a…

Diesel Engine Combustion Process
Introduction Diesel Engine Combustion Process | A diesel engine can keep a heavy truck moving for hundreds of kilometres, power construction equipment, run generators, and deliver strong torque without using a conventional spark to ignite its fuel. But how does that actually happen inside the cylinder? The answer lies in the diesel engine combustion…
