A leaf blower, commonly known as a blower, is a device that propels air out of a nozzle to move debris such as leaves and grass cuttings. Leaf blowers are powered by electric or gasoline motors . Gasoline models have traditionally been two-stroke engines , but four-stroke engines were recently introduced to partially address air pollution concerns.
Walter Owen Bentley replaced the Bentley 3 Litre with a more powerful car by increasing its engine displacement to 4.4 litres (270 cubic inches). A racing variant was known as the Blower Bentley. Bentley buyers used their cars for personal transport and arranged for their new chassis to be fitted with various body styles, mostly saloons or ...
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
Gas-powered leaf blowers can register as high as 100 decibels at the source (the levels decrease with distance). It seems everyone has a leaf blower or a landscaper who uses one, often at ungodly ...
The four-stroke engine is more efficient when running at full throttle, while the opposite is the case for the two-stroke engine. When a small car under heavy load runs at half speed, the engine automatically switches to the two-cycle mode, which is then more efficient. The research on this showed a 27% reduction in fuel consumption. [8] [9]
Blower: touring model 175 bhp (130 kW) @ 3,500rpm; racing model 242 bhp (180 kW) @ 2,400 rpm; The Blower Bentley was born, [8] more powerful than the 6½ Litre despite lacking the two additional cylinders. [12] The downside was that Blower Bentleys consumed 4 litres of fuel per minute at full speed. [10]
The outcry over leaf blowers has grown so loud that in October, California Gov. Gavin Newsom signed a bill that will spell an end to the use of gas-powered devices in the state.
Four-stroking is a condition of two-stroke engines where combustion occurs every four strokes or more, rather than every two. Though normal in some instances at idle, extremely high engine speeds, and when letting off the throttle, such firing is uneven, noisy and may, in cases of malfunction, damage the engine if allowed to continue unabated.
