2 stroke diesel engine vs 4 stroke diesel engine
Two-stroke diesel engine Two-stroke internal combustion engines are simpler mechanically than four-stroke engines, but more complex in thermodynamic and aerodynamic processes, according to SAE definitions. In a two-stroke engine, the four "cycles" of internal combustion engine theory (intake, compression, ignition, exhaust) occur in one revolution, 360 mechanical degrees, whereas in a four-stroke engine these occur in two complete revolutions, 720 mechanical degrees. In a two-stroke engine, more than one function occurs at any given time during the engine's operation.
Renault Clio The range of petrol engines consists of three options: a 1.2-litre 16 valve straight-4 engine, with a maximum power output of 75 hp (56 kW), a turbocharged 0.9-litre 12 valve straight-3 engine, developing 90 hp (67 kW), which can have a CO2 emission level of 99 g/km and a 1.2 litre turbocharged engine which produces 120 hp (89 kW). A turbocharged 1.6-litre four-cylinder engine, capable of producing 197 hp (147 kW), will be featured on the Renault Sport version.[50]
