Two-stroke engines which use crankcase compression do not require a crankcase ventilation system, since all of the gases within the crankcase are then fed into the combustion chamber. Many small four-stroke engines such as lawn mower engines and electricity generators simply use a draught tube connected to the intake system.
The sensed temperatures are compared and if the compressor temperature is not a specified amount higher than the lower of the other two sensed temperatures, then the crankcase heater is energized. When the compressor temperature rises to or is a specified amount above the lower of the other two temperatures, the crankcase heater is de-energized ...
The lawn mower was invented in 1830 by Edwin Beard Budding of Stroud, Gloucestershire, England. [1] Budding's mower was designed primarily to cut the grass on sports grounds and extensive gardens, as a superior alternative to the scythe, and was granted a British patent on August 31, 1830.

Rope start (also called pull start [citation needed] or rewind start [citation needed]) is a method of starting an internal combustion engine, usually on small machines, such as lawn mowers, chainsaws, grass trimmers ...
Core plugs can also sometimes prevent freeze damage to the motor. During the early stages of the freezing of the engine coolant a freeze plug will sometimes burst, and thus allow the coolant to exit the engine, before it might expand within the engine during the freezing process and potentially crack the engine block.

An early documentation of the design occurred sometime between 1174 and 1206 AD in the Artuqid State (modern Turkey), when inventor Al-Jazari described a machine which incorporated the connecting rod with a crankshaft to pump water as part of a water-raising machine, [8] [9] though the device was more complex than typical crank and connecting ...
