An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines convert heat into work via various thermodynamic processes.Petrol engines run at higher rotation speeds, partially due to their lighter pistons, connecting rods and crankshaft (a design efficiency made possible by lower compression ratios) and due to petrol burning more quickly. Because pistons in petrol engines tend to have much shorter strokes , typically it takes less time for a piston in a petrol engine to complete its stroke . High quality with amazing price Easy start Low noise level and vibration. Large stable power output. Easy-pull, quick starting. Low fuel consumption.
