Mod 2: Engineered products

• Brake systems: 2 strokes, 4 strokes, diesel, and petrol engines
• For 4 strokes systems: induction, compression, ignition, exhaust
• In Diesel engine, an injector is used to inject diesel into the mixture of the compressed gases to ignite it
• In a petrol engine, a spark plus is used to ingnite the compressed air and power the piston down-wards
• In a 2-stroke engine, the pistons simply moves up and down and performs all four phases of a 4 strokes engine in one cycle
• Lawn mowers use two stroke, four stroke, and sometimes diesel engine depending on the lower and it's use
