Jd Bug 28 HP Diesel Engine

Diesel engines typically operate at elevated intake manifold pressure (e.g., via turbocharging) and are not prone to knocking or pre-ignition as are premixed charge gasoline fueled SI engines. As a result, diesel engines can produce significantly more torque at low engine speeds than naturally aspirated SI engines.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 diesel engine to complete its stroke
