The engine used clockwise rotation as a standard, but some counter-clockwise engines were produced.

However, in earlier engines, the governor would cut off the fuel air mixture completely. Eventually such engines were rendered obsolete by the lister stationary engine dating of a universal power take off PTO system on tractor s, which could drive stationary equipment as well as mounted implements with much higher outputs than the average small stationary engines.

Today, most governors open and close a butterfly valve to control the amount of fuel-air mixture entering the engine.

The governor can use one of two techniques for controlling speed. The four-stroke cycle design was by far the most common, but Pettera British manufacturer, developed a successful two-stroke cycle design. Later for safety, cleanliness and longevity the design moved towards enclosing the working parts and using sump lubrication.

Whilst large power station. On a medium size engine such as a 6hp, the engine can be adjusted so that it only fires every 10 seconds or so when it is not under load.

The fuel tank was moved from halfway up the engine to the top, and the shaft-drive magneto was replaced by a chain-driven unit in the early s.

This outward movement is used to restrict the engine power to limit the speed.

As the speed increases, centripetal force causes the weights to move outward against the pressure of a retaining spring. D's were originally painted mid Brunswick green, but some World War II engines were painted in olive drab. For non-PTO equipment the arrival of the reliable electric motor or the small, light, high-speed petrol engine meant that even small machines could be driven by their own motors, making dedicated power units unnecessary.

When the engine is running above a certain rpm, the exhaust valve is held open, and the magneto is prevented from generating a spark. Sectioned Lister D Throughout the years of production, the engine changed very little.

This was easily corrected by the use of a rubber pipe. This is a simple negative feedback control system.

Once the speed drops, the governor allows the exhaust valve to close and the magneto to fire. The engine was a 4 stroke poppet valve engine, and, surprisingly, has overhead valvesinstead of side valves and a simple centrifugal governing system.

A paraffin-fuelled engine was also available, called the Lister DK. The engine was started on petrol, but could cut over to paraffin by means of a 3-way tap.

If the engine slows down, the centrifugal force reduces and the weights are pulled inward by spring pressure, and this movement is used to increase the engine power to maintain speed under increasing load.

These engines generally drove a wide flat belt to run a firewood cutoff saw, a pump, a reciprocating log saw, etc. The engine fires and speeds back up, causing the governor to keep the exhaust valve open again.

It had two separate tanks, one for paraffin, and another for petrol. Electricity Generation Before mains electricity and the formation of nationwide power gridsstationary engines were widely used for small-scale electricity generation.

While they were a very sturdy, reliable engine, they did have a few flaws, one of which was that the water tap poured water over the oil filler. The engines were used to power water pumps, generators, cement mixers and much more.

These engines are often called " hit and miss " variously called "hit or miss" because they do not fire on every available power stroke. A centripetal governor system was usually incorporated to regulate the engine's speed under varying loads. The engine speed is sensed by a pair of weights that rotate with the crankshaft.
