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 crankcase heater is normally on all the time, even when the unit is not running, though temperature sensors and set points may turn it off when not needed. A crankcase heater's sole purpose is to prevent refrigerant migration and mixing with crankcase oil when the unit is off, and to prevent condensation of refrigerant in the crankcase of a ...
It is possible for a lawn mower to damage the underlying soil, the roots of the grass, and the mower itself if the blades cut through the grass and collide with the underlying ground. Therefore, it is important to adjust mower height properly and choose the right tires for a lawn mower to prevent any marking or digging.
The most basic carbureted engines, such as single cylinder Briggs & Stratton lawn-mower engines, feature a single small throttle plate over a basic carburetor with a single venturi. The throttle is either open or closed (although there is always a small hole or other bypass to allow a small amount of air to flow through so the engine can idle ...
Choke valves are important for naturally-aspirated gasoline engines because small droplets of gasoline do not evaporate well within a cold engine. By restricting the flow of air into the throat of the carburetor, the choke valve reduces the pressure inside the throat, which causes a proportionally greater amount of fuel to be pushed from the ...
BUENOS AIRES (Reuters) -An Argentine court dismissed aggravated rape charges against French international rugby players Hugo Auradou and Oscar Jegou on Tuesday, drawing a line under a dark period ...
“Pennsylvania is a key battleground state, so I knew not voting wasn’t an option,” she says. Maria Fernanda Garcia Castillo is a 22-year-old originally from Smithfield, N.C., four hours from ...
A crank sensor (CKP) [1] [2] [3] is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.
